HPS CNC PORTED TB DYNO COMPARISON..

Today I was at the dyno doing some comparisons on 3 different Throttle Body's.The test vehicle for this is a UNTUNED 2002 Corvette Z06 with a CAI, and 1 5/8 Long Tube headers and catback exhaust.We tested a stock TB vs. a local shops hand ported tb vs. our CNC ported tb. The results are..



Stock Throttle Body ....................................375rwhp-359rwtq
Local Shop's Hand Ported Throttle Body ..........378rwhp-363rwhp
HPS CNC Ported Throttle Body.......................382rwhp-367rwtq

7rwhp gain and 8rwtq gain. Not a bad way to spend 175.00!

After I do a complete street tune on this vehicle, I will do another dyno run to see the gains. I have the dyno graph and pics of the TB and will post in the AM for you guys/gals.

Thanks,
Chris

Here is the pics of the LS1 CNC PORTED TB from a C5 Corvette.
Kinda hard to see the ridges, but she is pretty and perfect!
