And I just bought a 3.8" pulley 2 weeks ago according to your old chart. I am only planning on running a 9k rpm redline would this pulley still work well for me? Or should i get a 3.9" or 4.0" made.
It's ok to go a hundred or two hundred rpms beyond for a millisecond. Five or eight hundred beyond is not something you want to do. The 3.8 pulley should work out fine. I'm waiting for a 4.15 pulley to go with the a 9600 redline.
The bottom end was assembled and blueprinted by Mike Laskey. It's his "cookie cutter" block. Stock bore and stock stroke 2 liter. CP pistons, Pauter rods, Benson sleeved block.
The head is an Alaniz competition head with a mumbo jumbo mix of parts including Supertech, Honda, Alaniz, Manley, Eibach, Skunk 2, and so on.
Tony Fuchs did the assembly including studs and inserts. Goodies include a 70mm BDL throttle body, GM 3 bar MAP sensor, modified intake manifold, 4 inch cold air intake and a Honda head gasket.
The engine is good to 10,500 rpm but the cams don't support that speed.
That said, my factory f20c bottom end was good to 9500 rpm.
This guy thinks I'm full of **** so don't believe me.
