I was thinking about doing the cog set up but I think I am going to see what kind of boost I will get if I just increase the size of the pulley on the back side of the kit that's the pulley connecting directly to the blower pulley

On my mustang vortech setup just a 10% increase in the crank pulley jumped boost up from 12 to 14 on the top end but even better is boost was up all over the rpm range

I am seeing 8psi at 4000rpms and 14 psi at 6500rpms on my Stang
That's with a v2 vortech

928 impeller +. Water meth. And that pulley size increase a solid 13-14 psi on the top end could be possible I.e if you can keep belt slippage at a min.

More boost on the top end more boost you see on the lower end

Problem if they crack valve cam thing most of use would have to lower the boost on our cars less we want a new motor
