20 PSI was the tire pressure
 I only came out around 2 PSI of boost, but the .63 Garrett housing was good for practically instant spooling.

A little fun with the Gn's at Atco. - Video Mine is #6653 with the primered cowl hood, ran against the Nova, then spun bad on my second pass against Huber. That day I was running 100 octane av gas.
