Ls1
Im posting this here cuz there are alot of ls1 guys on here. butDo Stock Ls1s dyno 300 rwhp. I have a friend who i want to read thhis thread who does not belive they dyno at 300rwhp. He believes there only rated at 310 at the the crank. so therefore there is no way they can dyno at 300rwhp.

RE: Ls1
Mine made 305rwhp stock and 325rwhp with a lid/exhaust setup. This was through an automatic as well....my buddies car made 312rwhp stock through a manual. We both have the "slower" of the LS1's since we didn't have the LS6 intake stock. '01-'02 LS1's are known to make over 310rwhp on a regular basis, some see over the 320rwhp mark.
If you see an LS1 dyno under 300rwhp, something is wrong with it...I've seen cars make anywhere from 293rwhp, at the lowest end, to 325+rwhp on the upper end.

With respect to dyno numbers, there doesn't seem to be any real standard with respect to calibration, tie-down procedures, and other things that can affect the numbers so you shouldn't put too much importance in them. Elapsed times are a much better criterea because all 1/4 mile strips are the same length (1320 feet, duh!) and there are weather correction factors that can be applied to any timeslip.
