Those seem like air fitting connections, correct? They look pretty neat!

Right now we're working on wiggins clamps for the intake and cooling systems to make those jobs much faster and testing some inexpensive alternatives to wiggins.

What alternatives are you looking in to? My brother and I would love to do wiggins clamps, but can't justify the price.

Have you considered dry break connections for the fuel and cooling system?

I haven't considered them for this car, I'm not sure how that would work with a lot of the configurations on it now.

There are a few alternatives on the market now. After this race when we get some testing I'll detail more.

Racecar Engineering is a fantastic publication from the UK that I highly recommend you grab a subscription to. Aside from the fact that pretty much every article in there would be right up your ally, the advertisers are fantastic. There's a lot of plumbing companies in there, offering dry break connectors and even Wiggins-type plumbing connectors. You can grab a copy at most well stocked Barnes and Noble or whatever major bookseller you guys have out there in California.

Racecar Engineering is automotive geek porn, no question about it. I just wish it didn't cost as much as it does to import it over here ($128/year). (I have a subscription to Practical Photography, another great UK magazine, and it's also small fortune; luckily, it's a magazine both my wife and I can enjoy, so it's easier to justify. I already have my Grassroots Motorsports subscription, and the wife wouldn't get much out of RE. )

Although, they do have an online version (individual issues) that you can subscribe to quite a bit cheaper. They made their December 2008 issue available for free, if you want to take a peek at the format.

But I'm a big fan of dead trees.

I think wiggins are better suited for the things I'm redoing in the near future anyway. I've read racecar engineering a few times and liked it. Some useful articles in there. I been meaning to subscribe and that online version is perfect! then I can search and archive thanks for that link!

on the race car, I have an update today.

So the bad news is the body shop is behind schedule. David got a metal splinter in his eye and a couple other things conspired to pull us off schedule. Problem is we dont have any extra time in the budget. So Bret is coming down here tomorrow and we will start working on the final fab work to prep or the race. We will be camping out at a hotel near the body shop. We'll be literally working on top of eachother. Test day is 21st at Infineon NASA event.

 

[logic]

It's the DSM way: finish the project the day of the event, then go race.

Since this is NASA, you have to hit a dyno before race day, right?

 

[gixxerdrew]

thats the way of all racing from what I seen!

Not following why do I need to go to the dyno before race day?

Since the 21st is a Saturday, I think I will come down to check it out and offer a hand if you need one. Let me know.

I'm a bit fuzzy on NASA regs, but I thought they handled classification based on power/weight? (I could very well be talking out of my backside here, though.)

 

[gixxerdrew]

Then I'll just tell them how much power we're making on that tune, I dont think we care which class we end up in since we're just shaking down the car. This will be my first time at an event run by NASA as well.

Dan, of course your help would be appreciated so give me a call or just plan to be there!

I usually pick up an issue or two a year for giggles. The information you can pick up from just one of those is amazing.

Damn read that whole thread... Started at 8:30 i think and actually understood and tried to research the things you do... I love straight track racing but i am starting to get into suspension mods and alot of things that i didn't know before i know now. I swear i learn more stuff on this site then i do in a college class( well some ).

The stuff you guys do to prepare is nuts... I love wiring( I am majoring in Electricity) but i dk how you could spend 60 hours in 4 days on it ...

I hope all goes well with you race. I'm sure you guys will do decent on your first run...

Its like forza 2 in real life

Best of luck and it is great to have someone who inspires people like you do...

This may have been answered on page 3 or 4 and I just missed it. But from my understanding, the louvors "vents" in the fenders is to take air from the wheel well and use it as a way to force the air traveling over the tops of the fenders and edges of the hood over the mirrors and upward. Is that correct or am I way off? This is an amazing thread, keep the updates (and pictures) coming man!

 

[gixxerdrew]

Simple explanation is that tires are a rolling disaster aerodynamics wise. They make a huge puddle of high pressure under the nose of the car and in front of the tire increasing lift. Not only are they a large protrusion but their motion pumps air the opposite direction of the cars travel. By removing the high pressure from the wheelhouse or even to the point that the wheelhouse is lower pressure than the air under the body you decrease lift or even create negative lift (downforce).

 

[e85_4g63]

Now I understand, so the benefits are 2 fold then? I understand what your saying. I'm just frankly stupid when it comes to aero, as I've never really learned about it. I'm learning a lot just reading and such, thanks for the explanation, it helped a lot.

Wow I'm really honored!! But honestly I'd rather see you spend it on some gear to protect yourself better or make your day to day life over there better. This is just a racing car and your over there doing a service for us with your life on the line.

I will keep updating the content because I know from my buddies who were deployed how its either your bored or your knee deep in $%@. So I'll try to keep the content coming in!

Much appreciated Andrew! I love to see the new content, it's so overwhelming at times though . But yeah since I'm a mechanic I've only been out a couple times in the past two months, so really haven't seen too much trouble. But yeah definately keep us updated, loving everything I'm seeing! Thanks for the kind words and keep up the good work!!

 

[gixxerdrew]

I'll do what I can to keep it rolling, you guys stay safe out there.

the entire vents on that scoote 2 hood are not centered. I'm going to have to live with it for now still happy overall with the look. They are both not centered and not parallel with the car. The hood is officially a POS but he's trying to make it work the best possible

 

[kahl23]

That has got to be the sexiest thing I've seen this week... Damn... I need a new girl.

Awesome thread, very impressive! I wish I noticed it before.

I was wondering, wouldn't it make more sense to have the louvers be on the inside of the fender, pointing below the surface, rather than having the blades stick up into the airstream?

Thanks guys!

I think your question the answer is depends on what your looking for them to do and where on the compromise spectrum you decided to build.

 

[KBR]

WTF is that hood Drew!? take that shit off and put the old hood back on!!


aite, peace.

 

[gixxerdrew]

I take it your not too fond of the hood karlo haha

Are you going to be running with the TT group? I'm just guessing you're around 3000lbs, and at your power level you'll probably be put into the TTR group. TTU has a maximum adjusted power/weight ratio of 5.5.

I'm really tempted to see if I can leave work early to get a look at the car.
