Anyone know what belt size to use for a 3.125 pulley on the Vortech System?

Wondering this as well.

Give Tony a call he has some coming in.

Should be about 0.50" - 0.75" shorter. There are a couple of guys on here running that combo, maybe they can jump in and comment.

does he have the 3.125 or the 2.87 pulleys coming in?

Awww so i cant just go to autzone and buy a genesis belt any more? lol

Andy i was the one Tony tested this setup on. The belt was not changed we reused the same belt. Most of us in here that have tried the 3.125 found it only changes the mid-range of the car. Not really worth using this pulley if you want more power in terms of numbers. Go with the 2.87 pulley.

both

Glad to see you have your shiny bright blue name already :w00t:

Correct but since we have been working to source belts and pulleys. :happyanim:

the hunt is over. :bow:https://sphotos-b-dfw.xx.fbcdn.net/h...61701197_n.jpg

OMG is this 12psi? I WANT NAAAAAAOOOOOOOW!

give us a call :w00t:

Tomorrow will do!!!! Mine mine!!!

You guys need to et some sleep!! Lolol!!

I used the stock belt on the 3.125 for a day and had a dyno on it no slipping was discovered. Frsmod.com. and Dynosty.com. @Dustin@Dynosty. Has the 2.87 pulley and belt ready to go as well.

I would say what I've heard but I don't want to relay the wrong message so hit up fa20club and he will tell you what's up.

For the pulley upgrade fuel pump is needed if you plan on doing E85 pump and injectors. And most important a tune update, that we provide for all our customers who purchase this from us.:wub:
