Hi guys, I was wondering how much psi I can push before I need fuel upgrades. I've read someone stacking a 70mm pulley/178 crank pulley with just a sl55 fuel pump, regulator and filter. Thats not bad in my opinion.

I was thinking about getting my pulley turned (after reading Sweet2002's thread) to 66-69 mm, haven't decided yet. I may or may not get a crank pulley (1k for new ones is a bit steep for me right now).

Another option is the 62mm sc pulley but I would have to find one used correct?

I'm really leaning towards getting my turned b/c:
1) Its cheap
2) proven to be reliable
3) I can upgrade to the next level when I'm ready where as with a 62 mm I might need fuel upgrades.

Thanks for the help guys!!!!!
