Default exact HP/TQ of LS1

Ok, I think we all know that the LS1 power capability was underrated. However, I'm not sure if I've ever heard an EXACT number for HP/TQ ratings. So, what exactly does the LS1 produce at the fly? Thanks!

I'd guess about 380 @ the crank. With a 15% loss, it would 323 @ the wheels. For an '02, that would be close.

340 LOW 380 high every engine is different so most will be in that range

Flywheel? Not many members here have actual engine dyno's. Most of what your going to get is RWHP.

Mine was 330 rwhp and 345 rwtq (weird I know it ends in 5's and matches factory numbers) stock.

Well most M6s dyno around 310RWHP/320RWTQ. That comes to about 365hp/375tq at the flywheel.

Bone stock. I've got the sheet around here somewhere and a video of it not to mention another moderator as a witness. Car doesn't even have the 345hp option.

Bone Stock?!? Like down to the paper filter, stock catback, everything!?? I just don't see how this is possible.....the only reason I'm not throwing a big bs flag is b/c your name is green.....

A car with good tires will dip into the 12 on a good day. Look at the horsepower numbers of cars of similar weight and you'll see they gotta be around 400 at the crank to good 12's. So an ls1 that dips into the 12s on a good day having that kinda power is a pretty reasonable assumption. If you wanna calulate the power from the mph there is a formula.

Use a conservative estimate of a stock car weighing in at 3600 lbs with driver and your making 373 hp at fly if your trapping 104 mph.
