Default 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.

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.

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!

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

Hey Slowhawk and Lance.
You want dyno numbers?

How about 361rwhp/378rwtq with lid, headers, pulley, maf and exhaust.
Corrected.

Believe it.

I was backing Zulater up. It's not impossible for a car to pull that. Stock he pulled 300 rwh AND? Slowhawk assumes his car was super strong because of his mods/hp ratio. You can't assume that man, because every car reacts to each mod differently. You can NEVER assume what a car might have pulled stock after it has been modded for the reason I stated above. Yea, it probably was uncorrected but who cares? Don't roll your eyes at me again.
