My car had:
PRCAI, Hotshot G3 header, UR pulley (2)
With stock cams timing was 18 deg
With S3 cams timing was 15 or 13 (showed no difference)
Stock cams Vs. S3 cams dyno
10 whp gain is pretty nice, but it'll be more useful once I get a higher redline.
The dyno chart on SE-R.net shows no loss in torque anywhere, but I do. I think this is the explanation why:
The excel data is eyeballed (OK, I actually put lines on the chart and read as carefully as possible) off of the chart on SE-R.net and my dyno chart, so its not perfect. The S3 cams in my car don't show any losses compared to ROb's car with stock cams. But my car with stock cams is much stronger than his car with stock cams at rpm<5500. But his car with S3 cams is stronger than mine with S3 cams below 6000rpm. I wish I knew why.
Anybody????
This next chart shows wheel torque for my car with stock cams, my car with S3's, and my old car with S3's.
I want to thank Eric W for setting up the dyno day and helping me with the charts. Thanks Eric.
