Well i finally got enough money to purchase my itb's after saving for 8 months. question is i have to hoods a cf hood thats going to be on the car mainly but i have the stock hood. I want to do a ram air intake throught he hood with custom horns kinda like a blower system on a supercharged chevy. but for those that running itbs would it be increase of power sucking in alot of air mainly outside/warmer air or would ti be more to get a air box and do cold air intake on it. its going to be a whild before i get these ont he motor cause of rebuilding but a little info before cant hurt.

 

Try contacting user AssPenny. He's working on something and has done a lot of research on this.

 

To get some ideas, check this page:

You can see the custom airbox and filter feeding the itb's.

Hopefully, that will give you some ideas.

Yup. ^^

 

i was thinking of something custom like this. custom runners with a modified STI looking hood where the ends of the runners would be for like a ram air.

it would only be used on track days regular driving i was put back on the other hood and runners.

what do you think yea i know my art skills suck didnt have photoshop

 

Interesting.

 

its something different. works for those v8's with a supercharger tap into it and see if it works. cant hurt to try

 

If you have horns or something going right to the cowl with an opening there, you'll gain from the ram air effect. It'd have to be street tuned after it was tuned on the dyno. You would also need to make a cover you can fit in incase it rains (just like V8's that have the filter sticking through the hood).

 

fwiw, make your scoop reversible and try it both ways. the reason i suggest this is because there is a low pressure area at the bottom of the windshield at the back of the hood. i personally just used spacers to lift my hood approximately 1".

well the place i will be having it tuned mainly street tune. but i guess ill be doing a lot of trial and error with this

 

If the entire rear of the hood is propped though, then you're sucking a lot of air into the engine bay. Something to think about if you're aero minded.

The direction of air flow is dependant on speed, btw..... it's pretty strange.

I'd suggest testing in different configurations. Cowl vs ram air would be a good one. Then you could try propped rear of hood vs closed.

 

At speed, the cowl will suck air in.

When I say cowl, I mean the very back of the hood. Not 6" foward from the back of the hood like muscle cars had from the factory.

Simple and quick test is to tape some yarn to the hood in various places and go for a drive.
