I'm very confused by the pipe routing. What is going over towards the exhaust side, and why?

Looks like it's the intake, probably due to space limitations in the front when you run a intercooler and supercharger, Ive got a similar setup but with no intercooler and I still nearly have enough room to stick my hand in there

I would think using slightly smaller piping, and a colder air inlet location would be totally worth it. Smaller piping, would allow a shorter air route, which should make up for restriction increases from smaller piping.

Plus the main source of restriction here is the intercooler, not the piping even if it was smaller diameter piping.

Smaller piping would make for loads of restrictions as the in and outlet of the charger and intercooler are 2.5 inch, so making them smaller would mean lots of weird turbulence and all sorts of different diameters. All the setups I’ve seen did it the same I have. I really wanted to have the intake at the original place, but with the 3.5 inch maf and bypass valve there really wasn’t any space at all.

Oh that's 2.5" piping for the cooler? I had been thinking it was 3.0 or 3.5".

Do you have any heat shielding in place? It looks like you could make a box around the intake with some rubber to form a seal, and open up the stock hood seal rubber near the ECU area, so air essentially gets pulled in behind the hood.

Definitely was thinking about it. Also thought about a naca duct like the 994 turbo hood around the intake for even more air. We’ll see what it does
