Well done! I need to do the same thing now that my 4" IC shroud has shipped. A couple of questions:Zero science involved... you can tell by the zip ties that’s the case... but ended up doing 4” to both sides and just some homemade fiber glass scoops

Literally molding around a Taco Bell cup a buddy had in his truck.
Driver side is a bit fancier... used a McD’s cup and split it off to both the ITG and the 4” IC.
forgot to take a picture after it was finished and mounted
Nah it's fine. Exige engine bay is wide open above the engine anyways. If you're worried just remove the muffler heat shield and open up that area to greatly increase flow.I think that an important part of the air flow from the side scoops is to circulate air through the engine compartment and out the back.
If you route all that air from the side scoops only to the intercooler as you appear to have done the engine compartment air cooling is eliminated.
I often thought about that picture, and one member here has a small scale copycat! But in the end I decided that water cooled would be better and that NA would be even better then that for now... One day once the car is all reliable I will go to water cooled turbo K24.....
1)Well done! I need to do the same thing now that my 4" IC shroud has shipped. A couple of questions:
- How did you secure the fabricated ducts to the clam
- What are you planning to do with the center inlet from the roof scoop, i.e., did you block/seal that portion?
that’s just some cardboard and aluminum foil away from a masterpiece!! keep those amazon boxes and snag a Home Depot gift card at Xmas... bam. In all honesty you could make one hell of a strong homemade scoop like this design it just wouldn’t be as “perfect”.I will stick will the 2ZZ I would never take the k24 route, if I had the ability to make my own fiberglass, I would totally copy that method.
Thanks. I'm going to mount these after some trimming and measure the airflow vs. a couple of other ducts. They're approx 1.75x7.75 inlet and 4" outlet.1)
they are bolted to the clam on both sides to this hole.
I closed off the Mohawk scoop to the IC and kept it being fed by both 4” tubes. I did open the roof scoop itself to add air throughout the engine bay (which is still blows my mind that the tiny little roof scoop was going to cool an IC)
The engine bay itself isn’t as sealed as a stock Exige. I run the rear delete and BOE ST exhaust with a lot of crap pulled out... plus those scoops don’t seal all the way so some air gets around them. The engine bay feels no different than it normally did post-road driving. Would need to track it soon to really see the temp differences.
Long story, but these are Roush NASCAR nose ducts that were suggested as a viable option from a friend who used to work at Roush. The part numbers are 30-089-0290 (LH Upper Nose Duct version 2) and 30-089-0291 (RH Upper...). They can be found on ebay occasionally and there is another pair for sale currently.Where did you get those? Custom?
