C5 put out some low dyno #s but still layed the smack down. Nice races!

Screw the damn dyno numbers! Your car obviously did great considering the stock stall and 2.73's. Is it just me or was that Cobra exceptionally slow?

Shor Tuning's dyno seems to be stingy when it comes to numbers!

I recall reading of a C6 Z06 HCI, and it only put down 510whp, when they generally knock out mid to upper 550's.

I would bet that this C5 would have put down another 30-40whp on a different dyno....

I figure the cobra would hang in there alittle better myself I knew Id blast him from a dig tho.

Its pretty stingy! I was hoping for 400 better but 375whp makes my car easier to get races haha

Vette rolled out. Spinning aint winning. I expected more from the Brah. The vette def throws down more than 375WHP but as was stated earlier its a lot easier to get the races you want when your numbers show up low on the dyno pull.

Still on stock diff? A built unit with 3.42s would be nice for cruising and performance

Yes untouched! Stock 2.73! A built unit is more then I want to pay! Id be happy with a 3.42 from a z06! Plus a auto is easier on drivetrain

True, you could always throw on some bias ply radials to absorb the shock as well if you don't care about top end mph

Your vette rolls out hard for the stall and gears! We just got done with a dyno dynamics dyno day, everyone but me was heart broken. I just didn't expect or hope for any numbers so I was happy just to see when my power fell off.
I made 399.6 but a cammed srt8 300c made 303, he wasn't so happy. I can't wait to get some runs in this summer!

You managed to find a 3.42 diff? NICE!

You will LOVE the difference of a 2.73, stock stall car to a 3.42, 3600 stall car.

I loved my Yank SS3600 and 3.73s on my old LT1 WS6 if I could have done it over again, would have did 3.42s for as much highway cruising as I did

Dyno dynamic dyno's read a little low. They are very good dyno's though. You can control the rate of acceleration with them.
