the curve looked jumpy, like the spark was getting blown out. i thought timing was an issue. i advanced timing 10 degrees and no change. fuel was 11:1. even if it was a fuel issue i wouldnt be 100hp short of last years dyno. at 12psi i was at 352 this time i'm at 250ish.....yuck.

i think its airflow. i had to do some major portwork when i put the T4 flange on the collector. but really i need to get the car back in my possession to look over the car again. it was a rushed install so i may have leaks that i couldnt hear because of the 4" dp.

the car drives like ass. spoolup is at 5,000rpm maybe 5,500. the curve looks smooth until the wastegate takes over then it gets all curvy and doesnt increase power like it should

right when it hits 12psi the hp curve is shooting straight up, then the fluctuation begins where the boost creeps and falls. and the hp stops gaining. i need to check the car over. i'll see if i can get copies of the wintech data for you.


i do appreciate your thoughts on this. dont let my frustration sound like i dont
