1983 Oldsmobile Cutlass Supreme Sedan LS Turbo Build

Track will tell the true numbers, but it made 500+ whp, 600+ ft-lbs thru an unlocked TH400 and Ford 9” rear end IN SECOND GEAR 👀

Also made 18 dyno pulls and it didn't blink an eye 😀
Fixed that for you....
 
I don't get it...? Why would it be in 2nd gear?
And if it was I believe that scews the numbers obtained

With my 3.25 gear ratio, the top of third was going to be nearly 180 mph wheel speed

I believe Tony is right, I remember something about this in my hours of mindless youtubing.

Understood. However being in 2nd at 1.48 to 1, isn't the rwhp/rwtq going to be off? By a lot? Being that gears are torque multipliers and all.
😆
In theory it would look like this "diesel Volkswagen" dyno result... 😉 😉 😉

With massive torque that was higher than HP, like skewed by like 100hp.... Allegedly....

We did some wheel speed calibration to match the rpms of the tires to the dyno itself

If you can get it to hook, then you’ll know what it’s doing imo.

Well cooked tires, half *ss prepped track, 16 psi in the Mickeys and 8 degrees on the hit is what it took for me. At 10 degrees I couldn’t get traction.
Refresh my memory, 275/60R15’s on the rear?

Tony is correct. 2nd gear pulls will joy give the same result as 1:1 in 3rd gear.

Good luck Chris - hope to see some results!!!!!!
