Dyno numbers, near stock L98

I dyno'd my 1991 Corvette last week-end. Minimal mods in sig.

251 RWHP/341 RWTQ

Going back to the dyno in a week or so and trying it with some nitrous. Wish me luck!

Excuse my ignorance, but I can't tell if you are being sarcastic or not. I kinda thought the numbers were pretty typical.

230 or so is what I see from most rock stock L98's, and mine has full exhasut so 250 seemed pretty reasonable.

Anyway, thanks for the props.

No i was serious, i've never seen one dyno that much. Or maybe nobody has ever posted up bone stock numbers before...the torque is pretty surprising though

they were rated at 250hp on motor from the factory, and should dyno around 200-210rwhp. thats incredible! great numbers! wow, longtubes and exhaust added 50hp at the wheels!

230 maybe typical for a vette L98 with the 58cc heads...its certainly more like 210-215 for the f-body L98s

nice numbers regardless, any times?

No times, the track isn't open here in Utah yet. Even if the track was open, any times from our local track are going to sound really slow. The elevation here is about 4500, but the DA is usually over 10k. Stock LS1's struggle to break 14.5 here, so I'd be lucky to turn a 15.3.

Not bad numbers at all. At a 15% loss to the rear wheels thats about 295HP at the crank. Allen
