NEED a smaller vortech pulley but which 1 should i get that would be safe enought for the motor and do i need a new belt with the smaller pulley where could i buy 1 from thanks.
I've run all three cog pulleys and both serpentine pulleys. What's safe I can't say as I'm at 6000 ft, but I'm running well over the generally accepted max 8 psi on stock internals. So far no problems, but who knows next time I punch it. Here's a little chart I made of what each combo netted.
Got mine from my installer, who ordered it directly from Vortech. I paid $87 for the 30T. You might ask here and the LX forums to see if someone is selling theirs. They pop up from time to time and you could probably save a few bucks.
