PPE IS350 Headers

[AZ JB]

Sorry about the delay guys... I think the results were TOTALLY worth the wait though!



BEFORE HEADERS - 265rwhp and 232 ft. lbs torque

AFTER HEADERS - 286rwhp and 246 ft. lbs torque


GAIN = +21rwhp and +14 ft. lbs torque.

Both runs were done on pump 91 gas from QuikTrip.


I am SO pleased with these numbers and so is PPE. We are also gonna keep looking for someone who might be able to tune this car. If we can raise the rev limiter we're sure the HP will keep rising, especially with the way the graph reads and the hp goes up.

Thanks again for all the support everyone! These results are so much more than anyone expected!! Let me know if anyone has any questions..

EDIT: I posted this later in the thread as well:

Alright, so I got it straighted out from PPE and where I got 21rwhp from..

At the dyno, the run showed a graph with a peak spike at 286RWHP. Once the computer smoothed out the graph to show what it shows, it printed a peak of 281. Ultimately you can expect a gain of 16-21RWHP.

The peak number hit during MY dyno was 286RWHP, which is where I got that number from.
