First off, mods are in the sig.





The A/Fs are looking really aggressive XD

Basically, there are two reasons why I think I could be getting more power:

First, my wastegate. With the way my engines ported, I'm pushing lots and lots of air. It outflows a ported S4 wastegate by far, so we took an exhaust valve head off a big Chevy engine and welded it on. Ported the hole to the max size of that flapper and it STILL crept at the top of third and 4th. So we settled on blocking off the left half of my exhaust at the y-pipe->muffler joint.

I peaked about 10psi on that run. My air intake temps were about 115f at the start and about 150f (per Haltech) at the end. When I get my Greddy FMIC(Still can't decide between v-spl and r-spl..), I should have much lower intake temps and I'll be able to run about 12psi.

What do you guys think?

 

Looks good, except for the 1500rpm span where you pegged out the wideband. You have the potential to gain a lot of midrange.

 

Nice AE. Clean and intellegently modified, well done. Good luck on getting it to where you want it.

 

yes. nice clean ae. and good numbers. i'm hoping for ~250whp at 12-13psi with some race gas on mine..

get an s5 turbo and get rid of that creep
