Remember buying $80 worth of $4/gallon race gas for my black 944 Turbo for Autocross day.
There was a local gas station that had it on one of their pumps. Don't know if it is still there or not.
They limited buyers to $80 of that stuff.

The compression on the GTS is high at 11:1. Not nearly as high as the 944Turbo at 16 PSI boost, just under 17:1 was supposed to be max at max boost.

The 944Turbo was built to handle 21 PSI boost, but if you don't re-torque the head bolts, they stretch, let the heads lift and burn a hole in the head gasket at only 16 PSI. Don't care if you heat cycle the head bolts using infrared it ain't the same as the pressures/stresses of a running the motor.
