Damn that's some power!

I'll post up my measly power graphs. All are bone stock k20z3:
Here is my previous log manifold setup, IWG GT3076 on pump gas:

Same setup, pump gas, on IMW dyno:

Same setup on c16:


Current turbo setup, t3 sheepey manifold, GT3076, recirculated EWG:
~11 psi, pump gas:

13-14 psi:

~16 psi:

Log setup went 13.2 on half finished race gas tune on street tires, definitely had more in it, but never got a whole lot of seat time at the track with it. Current setup went 12.044 at 119 on pump gas with slicks. Has more in it as well, but had to pull motor out as it is making a bottom end noise.

OK gotcha. Thanks for the advice. And I sure will post the graph once I get everything sqaured away. Which 4 port should I go with ? And how would i run the boost lines ?
