look, he made a hood for an NSX, he knows what he's doing, ok?!?! Maybe you should show a little more respect and just buy his product without questioning him. Do not disrespect a potential sponsor.

Me thinks that each car and install is different enough to justify a "try and see if it works" approach. There are various ways to resolve each issue too. I have a big *** radiator and fan which seem to manage my coolant temps quite well in the SE summer heat, in traffic (sans a/c).
Below is an image showing my plans to restructure the interior of the mouth. The top section may be wishful thinking, but the bottom is absolutely feasible. In my case I've got a larger radiator, but even the stock radiator could be lowered some to provide direct exposure to oncoming air by dropping the lower part of the mouth shrouding as pictured.
I agree- that hole just needs an insert with a finished edge

I am also going to do a vented hood eventually, but you can see the oil cooler on the left in the photo. Vented hoods are great for getting air through whatever fits in the stock opening, but the oil cooler was going to have to go in the fenderwell, where it would be destroyed by road debris, or behind the intercooler, further sacrificing the current airflow situation. I agree the car is a lot cleaner without the hole, but I think it's growing on me. It's definitely more race-car than street car at this point anyway.

Stacking exchangers works best when you have the hottest exchanger last to reach the passing air. So your boost air in the IC is going to be the "least hot", then the rad which will benefit because the passing air is still not as hot as the surface of the rad rows/fins.
The top won't work- not with the angle that steep. Another reason to build that bolted on front support so that it goes deeper into the bumper. I think that'd make a BIG difference in air movement into the mouth and through the exchangers.
If the support was moved deeper into the nose/bumper, then I think the contours would come closer to mirroring each other as the expand into the mouth.
y8s I am awaiting your drawings

also, has anyone here used the bell air scooper? I'm going to get that **** on the car as soon as I get home to work on it again. It would be really cool if that worked...and I don't rip it off on my first trip to the track.

I'm using it, and it's a great piece, but it does hang a bit low and you have to watch the curb 'stoppers' in parking lot spaces, and some stupidly high speed bumps.

I'd have a Bell scooper, or something like it, but then I heard it hangs BELOW the R-package lip. My lip is under 4" from the ground. A meaningful scooper would reduce that to sub-3", which is just absurd.
Myron (2/3rdsCobra @ M.net) has done this really trick setup that's like a BEGi scooper, but he cut a slot in the R-package lip. The duct goes right under the IC into the rad.

I understand that I want to pull air through the radiator, but what about the intercooler? I remember some discussion that turbulent air is best for an intercooler (which doesn't make sense in respect to radiator cooling) so would it be best to seal off my intercooler inside the sealed radiator air track? I'm thinking about building a rad box like matt andrew's car, with a seperate foil for air to the rad, and not the intercooler.
