Open floor for rule discussion for TTS. Voting on changes can only be done by the racers that have participated.
On my old setup, 109 stroker, cast unported GN1 alum heads, 210/210 110 cam I made one hit and it went 11.2 at just 16 psi boost through the stock airbox. It is a restriction, but I think I could just crank the boost up and see where it ends.It would be neat, are you considering that combination as it should fit in the proposed TTS rules. I would be curious as to what a 66 and stock air box is capable of running myself.
