I'm gonna do some runs at the track in a couple weeks with race fuel and see if the 3.2 helps or hurts.
So Allmachtige, what is your conclusion on the 3.2" ?
I had been getting only 9.0 psi with the 3.4" pulley.
With my 3.3" I get about 1/2 lb boost to about 9.5 psi and it seems to run great.
With the 3.2" the boost jumps another 1/2 lb to 10. psi the engine runs hotter.
It feels stronger.
Don't laugh but I still don't have a laptop to run with my AutoTap to check for KR.
I have reinstalled the 3.3" and it runs cool and strong now.
