when someone claims brake horsepower they dont mean at the brakes, but rather at the flywheel, the brake was just a mechanism they used for measurment.
although there are no wheels on the car, the dynapacks numbers are meant to be at the wheels. a dynapack actually measures torque where as a dynojet calculates horsepower based on the amount of time it takes to accelerate a drum. the biggest advantage of the dynapack is the steady state feature. this allows to dyno to lock the car at a certain rpm, and by applying a load to counteract the engine. This load forced the motor to sustain the same rpm but increases the load on the motor(imagine going uphill, more throttle but rpm doesnt move much). This allows the tuner to hit cell's on the tuning software they wouldnt normally be able to simulate without a load bearing dyno.

good info to know about dynos and such. Just goes to show that every dyno is different and unless 2 cars are measured on the same dyno, numbers are just numbers. It's more of a tuning tool.

Wow, glad to see you guys got into the balts. I was out there a few months back when the Ryans from RD Fabs came out w/ the RHD civic. If you're going to get into HPT w/ the Cobalts, then I need to talk to you. Shoot me a PM when you have a chance. This is very good news cause Ryan and I are digging into a project this winter...
That guy is a joke around here.

Thanks for the dyno post! This is great news. Someone correct me if I'm wrong, but aren't these detuned electronically for the first 500 or so miles? I noticed that you dyno'ed at a pretty young age. Like to see another dyno at around 600-700 miles.
Thanks again!
Thanks again!

I believe that the first 500 miles are "sugar coated" by the PCM, I'd also like to see results after the car has a few more miles on it...

hp tuners just repsonded to me after i sent them the data from our cobalt. it looks like they should be able to support the cobalt ss/tc with their next update due out soon. this will open up many doors for this market.
