The 14b Drag Race Discussion Thread

[Phil1320]

Well, I'm not sure what boost level I'll land on. It depends if I can make more power above 21 psi with a better FMIC than I've had in the past. I'm not so certain much more power will come with any more boost than that, no matter what. However, some of these guys that tune for the spike may have something else to say about that. However, even though I shoot for record numbers every time I'm out....if I'm popping turbos and wrecking stuff in the process it would really cancel it out for me. Granted, my car goes to the track and comes home on a trailer no matter what, but, until my last outing I've always pulled it on the trailer under it's own power....I want to keep that trend. Basically, no one run wonders here. I'll just talk to FP and see what they recommend.

Is everyone running coolant lines? Thoughts?

Is everyone running coolant lines? Thoughts?

Up until now, the coolant lines have always been used. Once I get back out drag racing...they won't be on the car. I have an NT water pipe. But that won't last long. As soon as I go roadrace the lines will be reconnected and never come back off.

 

[GRNDSM]

I haven't run coolant lines on my "converntional bearing turbos" since the late 90's. That includes all 14b and 16g turbos. However, I do not put more than 5-6k miles/year on my own cars.

If I was driving over 15k/year, I probably would have reconnected the water lines.

And I always ran coolant line on ball bearing turbos!

My car is finally coming together with the 14b. Got a few miles on the motor now. I'll be working with pneumo tomorrow to get some street tuning done. Right now it's still on crappy CA 91 octane. Once I get the funds together to go with a fuel cell, then I'll convert to Ethanol or some form of higher octane "race gas." I have a few things left to do before the car will be optimal:

Slicks
suspension
remove nuts/bolts from interior
remove interior brackets
remove sound deadening
lightweight hood/hatch with lexan
gut the doors
remove the headlight motors/adjusters
fuel cell in place of gas tank
lightweight seats instead of stock seats
sheet metal to fill in for sunroof (when I decide to remove the sunroof)
new windshield (mine is cracked)

There are a few other odds and ends, but that's the biggest part. As you can tell, I still have a lot of weight I can save from the car. I'm not exactly sure what the car weighs right now, but I might go to the local landfill and find out. It will get me within 20lb one way or the other!

I have been running all my coolant lines. But plan to pull the Heater Core and blower motor for some decent times. But like Phil mentioned, I too will be having some sort of recirculation with the heater hoses for Road racing and AutoX.

Good to hear your making progress.

I have made some progress with mine as well. Right now just getting the weight down. Straight forward for me because I still have kept all my factory options till now. So that is easy weight to pull.
*Pulled the cruise control and all associated parts
*Pulled the A/C and all its components under the hood
*Pulled factory fan from infront of the turbo(that thing is a beast)
*Wired a single slim 14" FAL fan to handle cooling

Next will get the dash out and pull all the heater stuff(core,blower, ducts) trim up my doors, trim up the hood, pull wipers and motors, pull rear seat belts, rear seat brackets and all mounting points-still had that in there to give family and friends incentive rides

Thats the big stuff for now. I figure if I can get the cars weight down by 150 to 200 lbs, I will have an "Easy"(if there is such a thing) 11.

 

[1SloEvo]

If you've already pulled the A/C components and the cruise control, the heater core and fan along with the other random parts you mentioned will get you an easy 150 lb. My car is pretty stripped out, but as I mentioned above, still has a LOT more that can save weight. I too will be cutting my stock hood up to shave 'free' weight before I spend the money on a fiberglass hood.

Can't wait to start seeing some times reported from people hitting the track this year!

Just wanted to say thanks to Dave (pneumo) for driving up to help me out with tuning the car today. The car is running very strong, even though it's on 91 octane right now! Can't wait to get some race gas or E85 in it to see what she will really do!

Hi Brandon,
You're welcome! It's always a pleasure tuning a car that's already sorted out.(except for the idle issues, but that should be an easy fix) It leaves me free to jump in the car, do some pulls, crunch the numbers, raise the boost and watch the power climb! Props for keeping the car on the road when it was spinning the tires and torque steering all over the place!

Still on the oil pressure topic, I found this oil lubrication system tech sheet for MHI turbos from Forced Performance, http://store.forcedperformance.net/merchant2/graphics/subaru_oil/MHI_Oil_Specs.pdf. It calls for:

• Required oil pressure at full load rated speed of 2-5 kg/cm2 (28.4 - 71 psi)
• Recommended oil pressure at full load rated speed of 3-3.5 kg/cm2 (42.6 - 49.7 psi)
• Minimun oil pressure at low idle warm conditions of 0.8 kg/cm2 (11.36 psi)

(1 kg/cm2 = 14.2 psi)

I'm hitting a max of 27 psi from the head now which is a tad below the required pressure and quite a bit below the recommended pressure. I ordered a OFH feed line yesterday and I will play around with restrictors. I will keep you guys updated.

 

[GRNDSM]

The only value that I question in this spec is the hot idle pressure. Has anyone ever seen over 10 psi in the head during HOT stock idle? I haven't... So if this the case, Mitsu OEM was designed outside of their own specs? That doesn't seem to be likely.

This is what I like to hear! I respect full weight street cars and all, but a 3110 lb. 4 cylinder car is a porker.

This is the best mod for these cars bar none.....best part.....it only costs time, not money

*Update on my stock(14b) Talon*

Well, today was the first full day I was able to dedicate to the car in years(8 to be exact). My goal is to not change anything performance wise from my 12.1, 2004 pass. I just want to trim the fat on the car. So today me and my brother spent the day doing that. The pile of stuff we removed is impressive. I even pulled my front mount and bov in place of the stockers just so I can clean things up a little. My GTR front mount and bov will go back on when done. Still alot to do, but it ifeels great getting my hands dirty again.

Just reweighed the car. She is getting lighter. 2520

 

[9!'clipseDOHC]

Ran a new personal best, but not by much. Best 60' was only 2.2, I just wan't hooking tonight. I ran a 13.10 @ 112, best before was 13.18 @ 110.

I did get a sweet video of me taking down a 'vette tonight though!

[1SloEvo]

That's really good mph. That thing is going to be really quick once you get the 60' down!

 

[SBstar]

Nice job Nathan! You've got to start picking on someone your own size though, you know those heavy pigs can't hang with out little stock turbo's!

 

[1SloEvo]

A ~3300lb V8 is not such a pig when you consider an AWD 4 cylinder eclipse tips the scales within 150-200 lb of the same weight. Of course Nate being FWD makes a difference, but now you have to deal with the traction issues.

 

[9!'clipseDOHC]

Thanks! Yeah I know it's all in the launch but it just wasn't grabbing last night. I'll keep working on it.

Thanks! He wanted to race again after this too and I beat him again, .

Nathan, awesome stuff and good mph. Should be a 12 sec car easy. I was suprised how low of Psi I had to have my street tires to get them to hook properly for the drag strip. I can only imagine how difficult it would be for FWD. Were you riding the revlimiter intentionally there on 1st? From the video it looked and sounded like it took you some time to hit 2nd. That delay is when the vette reeled you in. That may have been the difference between a 13 flat or 12.9 something.

It stared spinning real bad in first but my mph wasn't high enough for second yet, that's why I held it a tad longer. This was my first run of the night and I was in the Unprepped lane. I ran a 13.9 that pass. I got down to the 13.10 later in the night.

This was only my second time using the Hoosier drag radials and I'm still trying to get the pressures right. I went down to 15 psi and it was still spinning first at wastegate pressure and a 3500 rpm launch. It was hooking WAY better in November.

I hear you man. Thought this was your 13.1 run. That is one of the crucial ingredients in killer ets. Finding that perfect tire pressure and launch rpm. Also a track that is consistently prepped well and plenty of seat time.

I swear everytime I see your outings, I get more and more motivated to get my car running right again and to the track. Cant do anything this weekend. Have to go to San Antonio. Always something holding me back. But the car is going to hit the track no matter what this year.

On a separate note, got alot out of the car. Wow I must have 20 lbs of wiring that could come out. Need to get a tuck going like you did. Just electrical is not my thing so it might be slow going for me.

Well here is some more motivation for you... I didn't just go to the drag strip yesterday I'll be updating my build journal soon with lots of pictures and videos from my busy day yesterday autoxing and dragging.

Electrical isn't my thing either, I had to struggle through it.

Car looks great in the pic. Got to have to see some of that GoPro video.

Very nice Like a base model neon now haha

What weight was your 12.1 pass?

 

[ArcticTsi]

Very nice Like a base model neon now haha

What weight was your 12.1 pass?

2740(weighed in last week at 2720 without my exhaust, just weight the exhaust seperately and it was 18.9 pounds) for the car and I am usually hoovering around 180, but back then could have been closer to 200.

Still a fair amount that could be done with the car, weight reduction wise.

Still all the factory sheetmetal and glass. But for now may just trim up the doors, trim up the hood. Cut my own driver/passenger side windows. Not yet sure exactly how far I want to go before the cars next outing. Getting a little anxious to see her run again.
