I don't know how this dyno compares to others, but I feel the numbers are pretty accurate. In any case, this will be my baseline. Next dyno will be with a 2.8, then finally with the TVS.

I could skip the 2.8, but I feel that with so many people running OTTP Stage 1, it would benefit the community to share my results going from 2.8 to TVS.

Comments and criticism welcome. :twothumbs

nice numbers!

very nice

great numbers similar setup to mine !! have you tried increasing the rev limiter to 7250 rpms ? thats the only reason i want the gm stage 3 computer. i wont have to worry about bouncing off the rev limiter at 7000 grand in first :) 1st gear is soo friggin short.

wow just looked at the temp. 96F !! those are fantastic numbers for that temp.

It's a corrected reading. Meaning it would dyno the same numbers in 30* or 90*. That's the idea of dyno corrections.

In some cases a dyno will over correct and produce better numbers in warmer weather.

got ya ... regardless excellent numbers !! i don't remember what my dyno print out look liked when i had mine done. its been awhile .... so i forgot about correction factors and such :twothumbs

Thanks guys. :D

I'm not one to make excuses, but my car was misfiring really bad that day, so I told the operator to only wind it up to 6750. I shouldn't have even put it on the rollers but decided to risk it anyway.

About the misfiring: I was getting a P0354 Coil 4 Control Circuit code. I put in new spark plugs and swapped around my coil packs to see if the code would change, but had no success. I finally found it to be a wire (part of the coil 4 circuit as indicated) that had rubbed through and was shorting out when it would make contact with anything. Every time it would short, the car would misfire. Damndest thing.

I plan to go back next month and will re-do this run all the way to 7250, despite the scary IDC and IPW numbers I was seeing that day, since it seems to have still been making power.

I'm almost tempted to invest in valve springs just to experiment with going to 8k with GM S3, but that is probably a very foolish thing to do on these injectors lol.

Deff. PM me or let me know how you make out when you wind her out to 7250. i want to see if the power keeps climbing. i know it wont be much more, but im looking to buy the gm stg 3 ecu so im just curious.
