Dyno results are in. After installing American Racing Header's, cold air intake, and a pulley and with some masterful tuning done by Carmen at the Vette Doctors the results are in 620RWHP

What size pulley and how much boost are you seeing? Which air intake?

Nice numbers!

If you could post the dyno would be a big help to clear up different information we are getting.

A/F ratio at that pull would be great as well.

Redmix I have had CEL issues as yoiu reade with my ARH's. Did carmen simply turn off the reaer o2 sensors to potentially aleviate this- tuning ror power is one thing and i am glad to hear your numbers are so good but tuning for emmisions/cel's appears to be different.

We really need to see a dyno sheet with A/F ratio, and max boost please. I think it will help us understand a lot about this car's fueling system and capabilities. :yup: It would be great if Carmen could answer some questions about the duty cycle of the stock injectors too.

Thanks.

Try to send Carmen a link to here. I know he posts on the vette forums sometimes so maybe he can stop by this thread.

Thanks for sharing your results dude. I MAY have to pay Carmen a visit sometime soon...

Redmix- based on your satisfaction and others I am going to try to keep the headers. Jesse/WFM has sent me an upgraded tune for a 9.5 crank pulley and high- flow cats to go with my intake mods. We'll see in a few days but i would expect 575 rwhp with conservative tune and auto trans
