Engine bay cooling improvements? DIY?

XwChriswX

98, are they doing any modding to your hood or engine bay to help with cooling since your turbo is up higher and in front? Not to mention the exhaust pipes coming back into the engine bay instead of out the rear?

Nothing has been done other than what I listed above. I'm contemplating modding the OEM hood or getting the VIS AMS hood, although I don't prefer the CF look and I don't want to take my chances of screwing up the OEM hood. I'm also contemplating buying a spare bumper to mod. I already have my design drawn up, it's just a matter or finding a body shop willing to work with urethane.

-create louvers
-making more holes in the front is not effective and creates lift (which is why louvers are needed)
-move radiator to the rear
-relocate fuse boxes and all plastic covered computer / electronic parts for more room in the engine bay - make walls (compartments) in the engine bay to direct the heat out to the louvers efficiently.
-wrap exhaust manifolds, intake manifolds, etc.
-front v mount and radiator shroud is a choice
-more suitable viscosity fluid for your motor and trans
-keep the heater running constantly as it uses heat from your radiator

if you want to use a fan or make louvers, try making walls (paths) for the heat to travel through before pulling out through the louvers. a fan spinning freely without walls to channel the air is ineffective.

also depends if you are building a race car or a street car.. it's all about channeling the heat.

This is for a daily driven street car with Stage II TT on the way.

So perhaps there's enough air coming in from the air dam?

Hood louvers? I would love to mod my OEM hood with louvers provided I can find something that's not too tacky, but functional. Hmm... I would love to get the manifolds wrapped. These two ideas shouldn't be too cost prohibitive.

Good thread I've been looking into this for a while now too. Looking for someone locally to mod my hood...

If you're going turbo, get some turbo blankets for the turbine housings. Wrap the downpipes. Manifolds are so small that I don't think you could practically wrap them, though you could possibly cover them a bit with a custom sheet metal heat shield.

If you use wrap on anything, I recommend the "DEI Titanium" wrap over fiberglass since it holds up to heat better, easier to work with, doesn't get brittle like fiberglass. I've seen old fiberglass wrap just crack and flake like potato chips after being on a car a while.

Downpipe and uppipes are fully wrapped and I have a turbo blanket. Check and check.

I want to see a good vented hood, something that is not just vented to look good but has true functional value.

No problem... I appreciate the advice. So far it's just the kit installation without any mention of wrapping anything, but it's definitely something to consider.

I talked to someone who would be happy to vent my hood with a pair of naca ducts. They would go near the front the hood on either side. To help you imagine where they would go...it would sit right over a Stillen SC.

Anyone interested in having their stock hood vented like that? If you pop your hood and look under it, you will know exactly what I'm talking about.

Oh and they sell those fender vents for audi's, I'm sure we can retrofit something.

what is in that corner of the bumper to cool?on the preproduction cars that was where the oil cooler sat, so it makes sense but for most people venting that spot will just reduce the pressure in front of the radiator. vents in the bumper for intake and brake cooling, vented hood, and vented fenders connected to the back of the engine bay to let the air out is probably going to be it for engine bay cooling without making a full under tray to suck the air out under the car.

With temps hitting 100F+ all week, are you guys hitting 220F oil temps? Last year, I hit 220F numerous times and the car would lag often. I don't know what it is, but I've not seen anything higher than 210F the past several weeks of driving even with the A/C blasting.

Opening up the fang vents can't possibly make much difference right?

It's difficult to tell what happened since the accident repairs late in March, but something's different.
