Good point but I do not have any "ducts" in or on my car. Also the cardboard was just used as a template (only good picture I had). The final design is 4 inches away from the IC. This means that the hood has a "vent". Rules say hoods are free. Also my hood is vented less than most after market bling bling ones. Thanks for the concern.

Answers for speedjunkie:

Do you have fans mounted to the back of your oil coolers? Yes one 10" fan.

Do you have any problems with oil drainage from the turbo to the pan? Not at all, and I am using the front drain also. I believe I use -10AN on that one.

Did you get that exhaust flange from Racing Beat? Yes

Did you use 304 or 321 for that runner? 321 SS from Burns stainless. everything is 321 up to the 4". The 4" exhaust is 409 and it starts at about the rear of the transmission.

Are you running water/coolant to those wastegates? Not at this time. This is one of my next season projects because I have over heated the rear diaphragm twice at a race limiting my boost to 15psi which = slow. Also I might have to relocate the WG since it is close to the DP.

I can't believe you were able to route the WG dump back into the exhaust too, that's awesome. It was not easy, also in SSM we cannot run open WG's. All exhaust must exit rearward of the rear axles.

What brand IC core is that? Did you do the same size piping on both ends of the IC? the IC is a cheap ebay core, I was experimenting and did not want to spend big bucks on a IC if it did not work. Also it is 2.5" in and out. I think I have pretty good response if not too much sometimes. Bell IC cores would be my first choice too.

Have you ever used a different IC and different exhaust manifold with that turbo? If so, is there a noticeable difference in response between this setup and that one? I have not had anything different, I plan to change something this year if I have time. I went from a stock set up to this so with that it was a BIG difference.
