Anyone know what the avg. stock LS1 puts to the wheels for HP and TQ? Do the SS and WS6 models differ from the Z28 and Trans Am?

 

98-00 usually 285-300
01-02 a little more so usually around 290-310

there really isn't much difference in the SS/WS6 and the standard V8 models on a dyno since the ram air setups don't do much untill at 100+mph, and the exhaust really isn't that much better

 

MY LS1 and others have made a little over 300.

 

01-02 dyno a bit higher due to ls6 intake

 

I'd say 300rwhp is a safe medium for your average non SS/WS6 LS1's. Most (not all) SS/WS6's dyno a few more HP. It can be attributed to the better flowing exhaust and intake, if that option was ordered as well

 

300~ish HP. There are high and low exceptions (280's - 320's).

FWIW, my '02 Z28 made 289 RWHP, 307 RWTQ through the A4 w/4.10's. Only power adder is a lid (I doubt the Flowmaster adds much HP? ).

Just as a note, do not even consider the factory rating of 305/310 HP as being even close to accurate.....and they didn't intend for it to be a rear-wheel rating! The later model SS's / WS6's with the lid and cat-back were actually rated 335/345 HP, which is a much closer rating (still less than the 'Vette, but it's almost accurate). The LS1 engine makes roughly ~350 HP, give or a take a couple obviously.....figure ~15% drivetrain loss on average, that comes out to 298 RWHP, so ~300 RWHP is a good "ball-park", and ~350 crank HP is certainly accurate too.

 

300 is a good average
