Well, we found the limits of my cheap all season Chinese made tires! John said theyd have a hard time holding on the drums and ended up being right.
The car ran awesome though and if I brought my slicks we could have pushed further...plenty of fuel left in it. It was 100+ in the dyno room

I ran a mix of about 75% 93 octane and 25% 110.
In the below 4th gear dyno, the tires spun just when it was starting to get fun! The boost hit 24 psi, the tires spun and turned hot and gooey, which promptly caused the boost to drop to 19-20 psi (less load on the engine).
Thanks to John at Secret Services for the fun afternoon.
