Here are some dyno graphs for car we just finished, it has the same low compression short block that Vinny will be running, This car has also our stage 1 cylinder head witch includes our upgrades valve springs and titanium retainers with a 5 angle valve job. This car was a rocket plane and simple.
The first graph is 12 PSI
Second graph is 14 PSI
Third graph is 15 PSI
