I went to Rosen autosports in richmond today. Did two pulls. First one was with AEM CAI, HS Header, and Nology wires. I Made 124 peak hp. This is low, but last time I went when I had the AEM CAI and Nology wires and i made 111 hp, so its not a bad gain. The reason for the overall bad number's I think is because of a clogged cat. Starting at the low rpms up until about 4.5k the headers improved hp by about 4. At 4.5k the increase jumps to about 9 or 10, then the biggest increase is in betweeen 6k and 6.7k, where I gained about 13 hp at the highest point. I then did a run with just stock wires (which where used, but not to used), and I lost 4 peak hp and about 1 or 2 down low. I guess ill be keeping those nologys. I will post the actuall graphs once I get them scanned in.

Wow thats kinda low a stock Sr20 usually makes 119-123Hp you might wanna adjust your timing and get one of those High Flow Cats (Random, Catco)

Is your car auto or 5spd? That would explain the 111whp baseline.

5 speed. pretty sure its a clogged cat.

Damn, a 13 HP gain with the HS header. I hope I'm getting those kind of HP figures with mine too.
