adding weight

I don't think I want to know how much more power he's getting than me. Rumor had it that his old second gen Integra was putting down 150whp. I find that kind of hard to believe but I don't know, if money wasn't an option and I had my own dyno, I might be able to do it. Might!

I predict that you'll have more torque and the power numbers will be pretty equal. What do I win if I'm right?

Actually Greg, I have to believe that you know exactly what your car's putting down, don't you?

We pulled 147 the weekend after we returned from Atlanta. That's on a full-tilt-boogie built IT motor, brand new cams and rockers, etc.

The problem is that dyno numbers are like...navels...everybody's got a different one. The numbers you get are perfectly fine for you on that day, but hardly count as ISO standards. Further, I believe Serra uses a DynoJet and I use a DynaPack: the former drives off the tires, infers the horsepower from rate of acceleration and backwards-calcs the torque; the latter bolts to the hub, limits the rate of acceleration (and can actually hold it to a specified RPM), measures torque directly, and calculates horsepower (as is done on an engine dyno). So, same way, same day is the only real way to do direct dyno horsepower comparisons...

Evan, I don't remember exactly, but I seem to recall I got 147hp at 6800 rpm (and it falls off precipitously after that) and 138 tq around mid-4000s... - GA

138 torque? Thought you'd get a little more. I guess my truck motor is good for something afterall .
