Low dyno numbers

Hello, I have a 01 Z M6 and have a question. I dynoed my car at around 5k and it pulled 346rwhp and 360rwtq. I dynoed it again at 12k and it pulled 333rwhp and i think 342rwtq. I just dynoed my car again just for the hell of it and it only put down 323rwhp and 341rwtq. Only change to car was Y2K vete rims. Bone stock my car put down 300rwhp and 320rwtq with 800 miles. Any idea why my numbers keep getting lower? See sig for mods.

Re: Low dyno numbers

Those don't sound like corrected #'s.
346hp,360tq with your mod's would make your car the highest HP off the showroom floor.
Did you do A/F's when dyno'ing all those times?

The 323hp/341tq sound right for your mods.

Re: Low dyno numbers

That's right...the figures you gave are HP at
the flywheel, not the RWHP or RWT as you stated...
unless you have some freak car....never know!

Re: Low dyno numbers

The Y2K vette wheels are heavier than stock Z28 wheels and tires and will cause you to lose a few HP as well.

Re: Low dyno numbers

Blake,
Read their ENTIRE messages. They are referring to the car being STOCK. Not with headers and other boltons. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
