Probably just good old fashion torque from a pontiac motor.You chevy guys wouldn't know about that would you.Congrats Stacy.

Lynn,quit giving away all of your speed secrets.

Really arent any secrets. We chased torque for years and it was a total waste of time. HP is the key at least in SS.

Whatever.Horsepower doesn't produce those nice wheelstands that you show in your pic.That my friend is a product of torque.

Well, my peak torque is about 5500 and my converter never goes below 6000. Stacy's never goes below 6500. I built a converter for the peak torque and the car slows down 5 tenths. I again tried to do the same converter and multiply it back out in rear gear to equal out the gear multiplication I lost, and it was still 2-1/2 tenths slower.

Horsepower is the true potential of a race engine. It tells you the abillity to enhance the torque using time and gear multiplication. Yes it all starts with torque, but it doesn't end there.

What rpm do you launch and shift at?If you don't mind my asking.

Lynn A McCarty · 10-19-2008, 02:13 PM

The on-board computer tells the story. No matter what the two step is set at, the converter instantly flashed to 6200RPM before the car moves. The computer allows me to overlay RPM, G-Force as measured by the accelerometer. It also gives me an instantaneous "leave RPM" on the screen. It is never below 6000 on the leave, or at any point in time down the track. By decreasing the leave RPM with the 2 step we are taking inertia out, not RPM, HP or torque.

With that being said, the converter comes back to about 6000 after flash, I shift first gear about 6200, and second gear at 7000RPM. Stacy's car you can add about 600RPM to mine.

Lynn, Do I understand you think you are working with HP number not torque using a convertor 500 above torque peak? What was your HP peak? Thanks

Lynn A McCarty · 10-20-2008, 03:20 PM

Dick,

Pontiacs dont have HP peaks, they have HP plateaus

. Stacy's motor varies 5HP across about 1000 RPM and so does mine. I recently bumped my HP up about 400RPM, but I am slow to loosen the converter. That converter was for a peak torque of 5000RPM and peak HP of 6200. I will do it probably 100RPM at a time.
