Time Attack Build Blog


(written on 2009.1.5)

I thought this would be a great place to start a build and race blog for my car. I thought I would start out with some brief (REALLY shortened) history of the car and the team. Some may know me as gixxer_drew, from SupraForums or here on DSMTuners. My name is Andrew Brilliant. I designed and drove this eclipse originally for Land Speed racing (since 2004) and I began the transition for Time Attack last year. During the 2007 Land Speed season, some competitors got a little unhappy about us putting 10-15mph on their records in a street driven convertible (running on hard top records) that street drove 400 street miles to the race and back. So they made some possibly valid points to the stewards and got enough rules made up to where the convertable top was effectively outlawed.

So we set out to transition the car to time attack. My first thought as you might imagine was that the peaky power band we had for land speed wasn't really going to be what we needed for the road course so I set out to design a setup that could achieve what few had done on an engine of that size, ~700whp with a usable curve and the reliability you need for a track car.

I spent all of 2008 turning the car into a "nice" car, a well mannered stable and drivable platform. Reliable at the power level was the priority. The chassis flex in particular required some close attention and getting around the basic problems of a FWD car much as possible or at least more than the other competitors in FWD class were. Late fall we got it on the dyno and this was the result of the engine development ambitions:

AVI (high res):

Quicktime (high res):
MobileMe Gallery

Now that I had the power-plant in line I have to focus on the other development aspects, cooling, tires, suspension, management, data, brakes, etc. Although some of those aspects can be worried about a lot less than a typical road course setup in time attack.

Here is a link to the car information. The mod list will be updated and the photos when I get new ones.

Douro Oni

The plan for this year is to run 2-3 time attack events (west coast tracks) , hopefully Silver State classic (at least for the standing mile) in the late fall and Super Lap Battle (if I can get an invitation). 4-5 races total, it's a self funded effort

Our team is sort of hodge podge mix and just a bunch of guys who live/breath/eat/sleep racing and built our own cars in our own garages. We need sponsors! The more help we get the faster we can go, ambition is not our limitation our own personal paychecks are.

We are lucky to have a couple of good sponsors for Matt and Curtis' car. My car has just started out into Time Attack. My Land Speed sponsor shop, KBR Performance stuck with me. YoshiFab (built my cage and a ton of other stuff) LG Motorsports and the guys over there have been really great to me and many long conversations with their crew has contributed much to the things I've learned. I cannot forget to thank Team NABR and the guys there. Thank you to my brothers.

This is our Driver:

Matt Andrew's


Matt is an amazing driver. You ever hear of the traction circle? Well I've never datalogged a driver where it was actually a circle on the G-plots before Matt.

Here is a photo of Matt and I at the close of last season with his Miata. This miata won the RWD Limited class overall for the season in Redline.



This is our crew with Curtis' Supra after winning Street RWD honors at Super Lap Battle:


A couple of quick action shots of the cars:






This is the Redline results poster. Check out the Miata next to the Brian Crower/Hancook tires car! I think I can speak for the whole team to say that was a real honor for us.




initial blog entry:

Unfortunately I had to pick a starting point somewhere so I decided to forgo the entire car history and start from today. Jan 5th 2009.

I decided to lift up my skirt a little bit on this and leak one of the very early conceptual body sketches and talk about some basic design concepts of the car. Things have changed a bit from the drawing, I'll talk more about when they are finalized and we tech at the first race. This sketch is pretty rough, however and many details unfortunately are intentionally omitted. I'm expecting some pretty rough feedback I know some of my ideas are unconventional but my experiences have lead me here. This is an investment in learning how to be fast as well as an effort to be fast.



The setup is a 285-295 front tire and a 245-275 rear tire. Which is looking pretty decent in the simulations although I've never seen it done like this, I have faith in the design I think the reason nobody does it like that is rules. The track is a few inches wider in the front. My goal here was to build a car with the characteristics of very mild understeer to neutral on exit, oversteer on entry as preferred for a FWD car but to achieve this without increasing rear natural frequency more than 0.25 hz over the rear and a balanced 50/50 roll resistance front to rear.

I haven't gotten to where I'm doing car simulations in CFD, I'm working on it. The aero may be adjusted down if tire loads become a problem. The tires that are legal for limited class have fairly mild maximum loads especially at the pressures we run. Warm up laps are especially worrisome. I also wanted a decent sized tire on the front to help manage the power/heat. The principle competitors in class are hondas with 2000lb curb weights so a really good weight to tire ratio. I have to capitalize on my strengths which is substantially more power production so I can push through aero drag. Downforce is critical for me.

The typical modus-operandi for FWD cars is to get the car to rotate by unsticking the rear, me I prefer to stick the front end so the rear rotates around rather than unstick the rear.

Springs and damper valves are luckily pretty inexpensive. So I can afford to take a risk there. KW (makers of my suspension) also does revalvings and turns them around pretty quick, so something pretty similar to running Koni's in terms of options, turnaround times etc. They can build to order. I can live with that.

2009.1.15:
I got the adjustable power steering working with the elecro-hydraulic pump. It's adjusted right and the steering response is now flawless. Huge improvement. Feels like stock with better feedback and slightly less assist. More linear as well, its perfect. Hopefully Matt will like it as much as I do. I can now adjust it for different tracks as well. High five myself, design goal achieved. The amp draw is extremely low for this pump but it's bulky, source was a renault clio the guy shipped it from Israel.



2009.1.21:
Overnight shipping from Taiwan is expensive. Thats the second part this month on overnight from asia. I keep thinking of all the beers I could have bought, thats a lot of beer.

Update 2009.1.29:
Short update, lots to do:
I finished up the aero package design for matt's car and send it off for him to work out with the fabricators. Gotta keep this stuff all under our hats though

Eclipse shut down on the dyno today looks like no signal to the injectors. Damn wiring again. I thought I could make one race with it as is but looks like not, I wont be re-doing it all for the AEM. Finally time to get a better ECU. I'll try to combine the Traction Control and the ECU into one box would be nice see what my options are for MoTeC.

Update 2009.2.2:
TEM Machine shop is building me the spherical bearing coaxial upper spring perches and they are almost done.

I first learned about KW in 2005 when I was at the britcar 24 hr race (the same race the famous top gear crew ran their diesel 3 series in, that episode was hilarious. highly recommended). I was shocked when I saw that about 50% of the field was running KW's including a mosler MT900R that I know comes factory with some well dialed penskes.

heres a photo I snapped in the pits:

sorry for the bad photo, it was a really dark nasty day.

A few pics I snapped of that GORGEOUS mosler just for some gratuitous motorsport pr0n. IIRC that car won the race.



I never got the perfect shot with the whole car framed motorsport photography is difficult 400mm lens in low light on a 140mph moving target.



Speaking of that race, there was this one driver that was hot, photo thrown in as an attempt to self promote my blog. I think shes famous? Anyone know who she is?


So back on topic, when KW showed up selling suspensions in the US and just so happened to be making a double adjustable drop in fitment I figured I'll give it a shot

some details on the dampers:
here is the front damper body, I dont give the germans much credit for picking color schemes but they are pretty damn good engineers. The upper spring perches that come with cup perfectly into the standard bilstein sleeve 2.5" upper hats to adapt to the 61mm ID springs. I want to try that out for the shelf springs to get an idea for where I want to move with the spring rates later in the year. I'll probably machine some new lower perches for 2.5" so I can use standard hypercoils.

Timken needle bearings for the spring perch lower are here. Need to get the upper hat designs over to TEM Machine then get the attachments for the linear pots.

Some details on the KW's

front damper assy, with the 61mm KW spring perches cupped over the bilstein 2.5" upper hat. Prototype spherical bearing to spring perch standoff shown.


closer photo showing the perfect (coincidence?!) fit of the KW spring perch and blisten upper hat


This is the compression adjuster on a rear shock, reminds of the Penske "sweep adjuster"

Auchung! Das instructions ist en Deutsche! (or something)



Apparently they didn't bother with such trivial pursuits as an english language instruction manual before selling the US market.

A shot of one of the VEI gauges, I havent tried it yet but the billet aluminum housing is pretty cool looking


This will be the basis for the airbox intake. Have to see how much I can increase the ramp without bumping into stuff under the hood, but wont know till I have the new hood in my hands



Update 2009.2.8:

here is my project for the next 8 days:



Nick form NS Fabrication is flying in to redo the car's wiring.

The car had gotten to where the only 3 times I had any trouble with it were all wiring related. The time has come to walk away from the factory harness. I sure as hell wasn't going to rewire it all for the AEM, that thing has been a thorn in my ass. So with the help of Nick we'll be knee deep in it. The milspec wires are amazing that spool on the left is 400ft of 14 gauge wire. The spool weighs more than the wire. The load ratings on the wire is amazing you can use a 10ga wire for a battery primary its nuts.


evening update 2009.2.10:

wheeldude.com is hooking me up with some very generous pricing on the new front wheels I needed 18x10 to match my rear wheels. Need a tire sponsor, desperately!

UPDATE: this one semi rendered, some small detail changes, dive planes, wing end plates, fixed perspective on the rear wing, fender louvers, rear wing wicker



side note: Solidworks is really cool, I'm learning as fast as I can. Its so much better than the stuff we learned when I was in University. When I'm camping out for 3 wks in socal while the cars in the body shop, I'll spend my evenings studying. I think solidworks is like learning another language. You can get proficient but it takes a decade not to have an accent. I'm not sure I could even count the number of features.

2009.2.11:
picked up the DG style upper hats today from TEM Machine


test fit on the KW using the bilstein upper hats. I need to draw up some new lower standoffs for bilstein specific upper spring perch and I think I can gain back some more travel if I revise them a bit.

complete damper/spring floor assembly



coaxial upper hat close up



Thanks to Rich at TEM for the hard work on those

2009.2.13:

I got a call from Matt today. Nitto tire is onboard, sort of. They are helping us out with a set of tires but we have that one set and have to prove the car with the tires. Pressure is on!

2009.2.14:

I've been camped out in Vallejo at the shop since thursday morning. Nick is cranking out the wiring and its coming out awesome. The SPAL fan controller is really cool. Had to sort out some details on the VEI gauge senders and wiring them into the Data aqusition. Worked out the pinouts for the datalogger and realized I had more sensors than inputs. I'll have to switch inputs as needed for a while until i can afford the Dash2 .

freq1: ground speed
freq2: RPM
freq3: TC MUX wheel slip rate
freq4: unused
1: coolant pressure
2: coolant temp
3: oil pressure
4: oil temp
5: transmission temp
6: boost pressure
7: fuel pressure
8: AFR
------- expansion module or Dash-3 needed for these extra inputs
9: suspension position 1
10: suspension position 2
11: suspension position 3
12: suspension position 4
13: steering angle
14: fuel temperature

Tired but still have a lot to do need to be ready to get the body shop so we have to be almost race ready before next friday. The suspension is the only thing we'll do just before March race.

There is so much info here to try to absorb. It's hard for me to believe you're doing what you're doing especially in this economy. The fact that you don't have sponsors makes it an even more impressive feat! You sure got a handful of work ahead of you though, I wish you the best of luck.

Wow! Your car is something that most of us can aspire to!

I love the "artwork"! FUNCTIONAL aerodynamics and nice looking. You wouldn't happen to have a shot of your rear diffuser would you? Maybe it'll give me a few good ideas, it's been something I've been thinking about for a bit. Do you have a full under-body tray as well?

I wish you the best with the car. I'd be willing to donate a bit towards the project, maybe you can get "tuners" to partially sponsor your car! Got a paypal address, someplace I could send a money order, etc? If enough people got involved, and behind your effort, all the little bits of change would add up!

The diffuser I dont have any good shots of I was just about to finish it up super clean like but now I redid the whole design which I dont have sketches yet and hasnt been built yet, its just in my head. This car is really being built by me and my friends, I never imagined that people would really come to help me like that but its great.

Thanks a lot man. I can tell you that would be REALLY appreciated I'm basically on a budget where I live on the absolute minimum to focus on the car. I camp out at the shop wake up early and work from 6am-3pm and then work on the car. I'm very fortunate to have such a great job and boss.

Your right those little bits would help a lot. Right now I have things like maintenance on the supra time with family and everything piling up on me because I'm putting all my chips on the table right now. I would take any kind of support I could get!

My paypal is andrewbrilliant@yahoo.com. If anyone sends money I'll keep it tracked, your name and everything and I'll let everyone know what the money was spent on in a spreadsheet. I had thought about that before like instead of people giving their money to vendors and then vendors deciding who to sponsor why not have people just sponsor cars directly. You can pay to have your name on the car, your own name or whatever name you wanted on there like "John Smith" or make up a name or your screen name or whatever you wanted. Maybe the top 5 contributers get big stickers and stuff. That would be kind of cool wouldn't it? Everyone I told that idea to figured nobody would donate or that especially DSMers wouldn't. I guess they were wrong! Maybe we'll probe to see what people think about the idea and see what to do about it if anything from there.

Update 2009.2.15:
rewiring in full swing, I have to get the car tuned on the dyno on monday. Nick put in long hours at the shop yesterday night. I'd been short on sleep for a while and fell asleep while he worked into the night.

This is the mess coming out of the car:

There were some connections with as many as 6 crimp/solder joints in a single wire.

nick constructing the new body harness

This was made more complicated by the alternator rewire to use an external voltage regulator, SPAL PWM fan controller and the trans cooler pump controller.

less is more! I can actually fit this ECU somewhere in the car besides taking up half of the passenger leg room


side view


In terms of sq/cm its less than 1/4 the size. The AEM box has a ton of empty space and a cheap, bulky circuit board. On my car space is at a premium and organizing things for easy maintenance is critical.

more of the mess that came out of the car, destined for the trash can


wiring up the fuse box


the new harnesses are compact, lightweight and clean. The wires are milspec which really cuts down on the space


fuse box all cleaned out for unused relays and fuses fitted in its new home for easy maintenance.


new alternator wiring, there used to be a huge jumble of crap down there


Here is Nick from NS Fab and the Piece de resistance:

BLinG!

That $865 for the Dash 2 is a pretty good deal man. Car is coming along great. Keep it up.

Yah it's pretty decent. I also looked into the AIM sports which is on Matt's car, the thing that had me sprung on the Dash 2 was integration with the data aquisition box I already have. AIM would be all on its own software which I didnt like their software (race studio I think it was called) as much. The ultimate would be to integrate the motec dash with the motec ECU but that thing is way more money than I can afford. SDL is $2300 plus I would need GPS and accelermoters and I think an input expander just to do what I have now, so roughly $3400. Its totally worth it for the motec hardware/software its way ahead of what I have now but I just cant afford it.

I think you should lean in favor of the Motec dash display for a few reasons. First, the construction will be far superior. It's hard to explain this over the internet, but with my Stack display the wire construction was all Raychem DR-25 construction. The connectors were high quality, not your typical Radio Shack crimp connectors. Rubber and metal used, not plastic. I can only imagine the Motec being the same (based on the the super car manufacturers that use both).
Secondly, technical support will be better as well as parts available. My local race shop (3R Racing) uses both Stack and Motec on their race cars, it's obvious who I go to if I need help. Motec also has an impressive forum. The sensors will more than likely be a higher quality. Also room for expansion with the unit. I know this is where it gets expensive. Before I committed to a system I considered my options, Stack and Motec have very impressive options for expansion.
I just think if you are building a proper race car, then use proper equipment. I know it costs a significant amount more (I even think they are super expensive), but I can tell from the outset this isn't budget build.

BTW, ever look at what McLaren Electronics has to offer? Ok ok, it will make anything else look affordable.

I couldnt agree with you more about motec and I AM leaning toward that dash, no question its what i want. Their software and hardware like I said are worth EVERY penny. The problem really is that theres just no way to make the money happen for that. At least in time for this season and I need to sort out those extra sensors asap because they are critical to getting the car dialed in. Its a question of wait until i can do it all perfect and go without it for now, or get something on the car so that I can do the minimum that I need to be out there racing, maybe winning and getting sponsors. I just dont really have a choice frankly. Your right its not a budget build, but I can't afford everything. Every experience I had with motec has been top notch. I also had a stack dash before which I sold but thats another story but yah I'm right there with you on the same page, I just dont have a choice right now.

I could have selected a Motec Dash and kept the AEM for example but I prioritized and this is where it ended up. I only had so much money to spend for this year. This is all my personal paychecks going in. If I wait till next year to have it that one degree better, the competition will be stronger by then as well. I think sometimes with racing you have to unwillingly compromise between doing it right and doing it right now.

3R racing is crazy

I see what you're saying. In your case I'd say go for the cheaper alternative for this year, and then upgrade maybe next year.
My buddy is considering upgrading his data acquisition system on his 125 shifter to a Pi System (from AIM), Pi Research is a good company out of England. It's coming down to cost for him as well, but the advantages a proper system offers is amazing. Alex Speed I believe is the only racer in his Super Pro class that uses Pi. And I can only imagine that is worth about 1/10.You can only feel the car out so much.
I know for Pi and Motec you can stream telemetry off the car in real time. But that is definitely going to be more money. There are some very cool/ geeky things you can do with those systems.

Telemetry is really cool yah, but we're not there yet. I'm the only crew guy who can even understand the logs haha

Pi systems are really good, agreed. I took their class in 05. It's really great but also super expensive.

I was just looking at the concept sketch of your car and I was wondering where the wing bases will be mounted. To the exterior body of the car or directly to the 'chassis'?

for the wing: Directly to chassis by still unknown means but a few ideas on the table

There is a definitely some under body work but no sketches for that yet.

Update 2009.2.16: Its 5:20am PST I just woke up, Nick's been working since around this time yesterday. The motec is all hooked up and things are strarting to shape up. John Reed emailed us a tune last night which worked flawlessly for the triggerdisk.com disk we were using before. Coils and INjectors were triggering properly, thats the last thing I saw before I passed out. Nick's been running "zombie fab" for the last 10 hours. Thats some hard work right there, start with 12 hour days for 3 days and then finish it off witha 24 hour day thats a 60 hour work week in four days.

Last night I ground out the openings in the center vent gauge pod for the VEI gauges. They are really nice the machined alum cases are just gorgeous here are some pics:





from left to right the gauges are for coolant (temp & pres), oil (temp & pres), boost/AFR




Kevin,

Thank you for those words! I never thought of myself as an inspiration, just some speed obsessed car nerd haha

Why not get a Painless fuse panel instead of using your stock fuse box. The Painless one will be smaller and more compact.

Drew, you're really taking this car to a level the DSM world hasn't seen yet (at least I haven't). The thought and engineering behind it all is simply awe inspiring. I'm interested to see how the modified KW's work out for you, that looks to be a great combo. I'm really digging the gauges, 2 in 1 for space savings and they're really affordable! Are you using their oil pressure sender for water pressure?

Oh, and feel free to send Nick my way after he's done with your car. I got a harness waiting to be finished

Nice Work.

And I told you that compromises are required sometimes

My budget of a car build while I was earning pennies as a co-op didn't quite cover what you've been doing for the past few years. Just curious, (and I know this won't be at all exact) but how much do you have into the car for just this build (as in, it's been through several iterations, but if you were to put a dollar value on the car as a whole after this road course transition...)

As for Solid works/design softwrae it shouldn't take that long... the first few months will be awkward. But it's more planning the model prior to starting that takes the effort. Getting a really good idea of the exact shapes you need, and thinking about the most efficient way to create those. Once you use it for a while, you start to be able to look at an object and build it in your head as a solid model, similarly as a machinist looks at an object and thinks about how it was machined.

Update: writing quickly! We are still working, so tired so tired. Motec ran awesome on the dyno got the tune 99% of where it was on the AEM. The motec is really really good, wow the car just runs better in every way cold start hot start idle, cruise all flawless and thats really amazing on 1600 injectors. John Reed moved over a lot of the AEM map for me and emailed it over the car started up instantly on the first try. Nick mostly and myself dialed it in the rest of the rest of the way we did have to change a lot of the map but that starting point was so invaluable and saved us likely an entire day. Nick wasn't sure before about the Motec but now loves it. Testing the Traction control here in a minute. Nick is going on something like 36 hours solid on the car. Wiring worked flawless from the first try, amazing.

Sorry when I get more time I'll reply to the other messages.

Yah but theres a difference between not having that last degree of wicked awesomeness and then having a total crap something But I'm reallllly opinionated on suspension stuff.

Wow, thanks a lot for saying so! I tried to do the best I could with what i know on every component and really think about the synergy of systems together. The gauges look amazing when they are lit up as well. Yep I'm using the same pres sender for water and oil!

Thats a really good point. This will work though could have just saved some space and weight by doing that. Nick pulled out all the relays and such that were unused I have lots of spares now.

Wow thanks man, I'll try to keep the reputation up! Also that bumper in your pic is that made of fiberglass? I been trying to track down a fiberglass bumper with no luck yet. Everyone is making urethane ones now.
