I was thinking over sized crank pulley and then underdrive the other components ie the alternator.

Im trying to avoid the turbo route only because with the gas prices going through the roof the magnetic clutch is kinda sexy :)

I would go turbo, when I had blitz sc I always had belt slipping issues. When I had a nice sticky belt, shearing the crank pully pin was common . Used hardened pin, crank pully pin hole slotted itself .

Only way to get the 1nzfe motor to take a sc application well, would be to pull apart the motor , send crank to machine shop to get keyed , and have a custom crank pully along with other pullies made in a 6pk width.

That is the only way to prevent belt slippage and spinning crank pully on crank shaft. Many people have blitz and dont even realise their belt slips . Should hold 9 psi to redline with stock pullies . I always put some VHT on my belt at the dragstrip.
