we call that "rice"

but at low speed (under 20mph), it probably helps to exhaust air out of it, if fans are on.

if you look at drag car, that's a common area for induction. it sucks in air. not the other way around.

pretty good aero basic here. even though drawing is a little first grader.

thanks guys...with cold weather approaching and what Ive learned from this thread I will wait till spring and spend the winter months doing more research. thanks!

hondaf1

thanks for the link, i'll read up on it.

i also found this link which has some good info also.

I think hood is tilted because thats the only way it will fit with his new swap.

that looks more like hood spacers to me. creates an effect where air gets sucked into theengine bay at the base of teh windsheild.

turbo produces a lot of heat. heats the oil, heats the engine bay. most s2k guys that run there turbo s2k on teh track suffer from overheating, both water and oil.

it doesnt help either that a fmic is reducing airflow to the radiator.

i have never done it, but i would presume, low boost setup, smaller then usual fmic, oil cooler will give you best chance to handle the rigors of hpde.

vented hoods may help, who knows. you really want air flow thru the engine bay. not just haphazzrd holes here and there.

again, your biggest problem is the giant heat creating turbo. search this forum, i think at least one or two guys had success with turbo and road racing. funny though, at best a handful have succedded, but a lot more have failed at it.

so ive been doing some additional research and no doubt feel that the list i made is good, but im concerned the enviromental factors and additional complexity will cause additional unessesary degredation on overall reliability. The primary culpret of this seems to be between the oil cooler and winter temps. I know a tstat will resolve this but it seems a lot of folks have had oil cooler issues in the winter. so for now until i get a deep understanding of this im just venting the hood and doing a new radiator. from there i will monitor my temps and if need be will add the oil cooler next summer with a tstat.

I would think the turbo blanket would reduce underhood temps considerably as well.

psychoazn

Bump, as I'm interested.

From my research, the biggest factors in reducing under-hood temps will be to cover the manifold, turbo, and downpipe.

Additionally, it would seem that oil and coolant temperatures are the culprits of any major failures, and that carefully monitoring them would be key.

Are you running oil and coolant temperature probe/gauges?

HvRRZ

So based off current discussions...best things to do would be to coat the manifold, turbo, and downpipe, oil cooler, vented hood, turbo blanket, radiator, and cooling mods

Probably would be best to go with a v mount set up.

this is the route I'm going only thing is a turbo blanket won't fit with the Full Race kit. But as it's been suggested on this forum, I'm going to take it step by step adding the components on an add needed basis starting with wrapping/coating and a radiator. I will update the thread as things develope.
