Pretty cool cooling mod

[roywilk1960]

Anyone try raising the back of the hood 1/4"? Might give just a bit more front down force.
It would let the air out and lower the temp.

It won't let the air out when driving. The base of the windscreen is a high pressure zone. Cowl induction after all is a way to force feed air into the engine.

worked in the past. Have done it many times.

It also lets the air out along the fender to hood gap.

How did you determine that it worked? Lower temps, better lap times, etc..?

Not to be a smart ass, my job is how I know it works. I've been making my living in motor racing for 28 years, Trans-Am with Jack Roush, Grand-Am with Riley, CART/IRL, been there done that...

Also not being a smart ass but most here don't know you from Adam. That is why I was asking for a little tech to back up your claim. 8)

Not a probem.
Just trying to use what I have learned to help.
They can take it or leave it, their choice.

Do we just use a 1/4" steel/aluminum shim at the back of the hood? Will the stock hood latch still hold or would we need to add pins?

 

[roywilk1960]

Good question. I'll look at mine tonight.
I do know that one big mistake that I've seen made is, lots of air in and no way to get it out.
There is a lot going on under the hood of this car.
If raising the back saves you from spending $850 on a new rad...

 

[908ssp]

There is no seal along the side of the hood now stock. How is raising it .250 at the back going to make a difference? What did you do for Roush sweep the floors?

 

[PTRocks]

There is a seal. I know for sure, because I detailed all around it on Saturday. Are you always this snarky with people?

Yes when they say stupid stuff like you just did. The seal is along the back so if raising the back would help removing the seal would help even more. Since neither will help and the guy making the suggestion of raising the back already admits that he suggests it draws air out of the side where there is no seal and there all ready is a gap. So raising still does NO GOOD.

Can you post some photos of what you did to raise your hood?

Hey 908, civility goes a long way. If you raise the rear of the hood, naturally the gap on the sides increase. Is it enough to do the job? Don't know, but bit sounds feasible. Either way, you can prove him right or wrong by trying it. Otherwise, you won't impress anyone with brash comments.

I'll take some pics after this weekend, been busy getting ready for Mid-Ohio.
I will leave the comment from 909ssp alone.

You going to NASA nationals? What class/car?

 

[roywilk1960]

I'm the crew chief for the #34, Conquest Racing Indy Racing League car. We race at Mid-Ohio this weekend.

I'm pretty sure there are some 1/2" round nylon spacers from McMaster-Carr. I will look up the part # and post.

Ordered one (M-8005-MGT) this morning. Should have it next week, prior to going to High Plains Raceway on August 5th. Sure hope it works.

How about an update John ;D
