Default I think the numbers are low

With Torquer 2 and LS6 ported heads and boltons in list i dyno'ed 390 rear wheels. I thought for sure i was going to go over 400. The guys running the dyno said that there were several factors such as it was raining at the time which was making it extremely humid, the gears hurt the car and the convertor was also killing it. What does this relate to in terms of under the hood horsepower and how much would it have been if it was a manual?

for what I've seen on here the a4 guys with a stall always loose a couple h.p. over the m6 guys. 390 is nothing to be ashamed off. just round up and say you have 400

Mine put down the same #s with the Torquer V2. But it would run 12.01 at 114 so who cares if the dyno #s are low?

Since the convertor kept engaging it only dyno'd around 350 torque. That seems crazy low but when i took it out on the street it was laying it down so hard i could barely keep her straight. Can any one tell me what they think the dyno numbers would have been if i did not have the stall, gears and humidity.

A friend put down 350-360rwhp through an m6 at MTI, then trapped almost 120mph. Not sure why the dyno was that low, but he was consistent at the track.

Was yours dynoed locked? That could easy explain the difference...In fact with your numbers with that mild of combo, I would say yes.....
Doesn't that Trailblazer SS kick ***......

Those numbers are not that bad, especially if you have a big unlocked converter....? The bigger the unlocked converter (generally) the lower you'll dyno....Take it to the track where you'll see the power your actually making....

If the numbers are SAE corrected (like they should be), then the environmental changes shouldn't matter.

They don't sound too bad considering you have an auto and didn't lock the converter.

Just because you have ported heads doesn't mean that they were ported for velocity. Depending on who did your heads, you could have big combustion chambers or huge intake runners and actually lose power.

Your numbers are right on. I did 388 RWHP & 350 RWTQ with MS3 & stock heads & bolt ons & the car ran 7.40s @ 91.

The heads are by texas speed and yes the convertor was messing the numbers up big time. On the street it feels unbelievable im just shocked that some guys are making the same numbers with just the cam!
