These are the HP numbers with the engines stripped of all accessories on the dyno's. It's still probably 50hp better then stock....but that's it.
A stock LS1 stripped makes 408-410hp, and the LS2 is closer to 500.
Once you add accessories and all that junk it robs HP from the motor.
They rate them without all the accessories OUT of the engine bay.
GM rates them IN the engine bay.
This is why prior to 1972 the HP numbers were so high. After 1972 they rated the engines power as it SAT in the engine bay, not on a dyno. It's why today's Hemi's can smoke the yesteryears Hemi's. The 60's 426 hemi had 425HP, well the new 6.1L Hemi would murder it. Hell even an LS2 would probably kill it. Different rating system. They're deceptively using the engine only power ratings like they did back then. Most engine places do......GM Crate motors don't though. They're rated the same as "In Car".
This is why teh ZZ454 is rated for 440Hp, but once you get them off the crate they pull 500HP easy on a dyno........cuz it's stripped of accessories still.
i thought it was prefferable and gave more acurate readings esp on FI applications!
Hey bro i didnt say there was anything wrong with the speed density tuning i just stated that is the type of tuning they use and maybe thats what they base there power numbers using that tuning.
Sounds like you got significantly ripped off. And after you dyno'd 315hp, you didn't go complain about that to them? Ask for your money back, or even sue them?
At least now you can warn other people, still an expensive venture though.
