I have teeth gear from Bartek and can't remember if they sent me a pulley that goes on the Charger bracket where the two black plastic ones go. someone mentioned i use 8v g60 tensioner pulley and  replace one of the plastic pulley. Does that sound right? I assume because the two that are on the Bracket are bigger than the one i believe they gave me and i can t find it.

Let me know what you guys use.

Hi, to calculate the charger speed on toothed pulleys, you have to know exact numbers of caharger and chrankshaft pulley. The safe zone for charger speed is 13 000 rpms, everything above that is some kind of risk, but normally you can spin your charger even more then 14 000 rpms , but very shortly ( 1/4 mile race or eny time when your engine spins on 7000 rpm or even more , thats also depends of your engine set-up and where you have max power ).

My chrank pulley have 56 teeth, and sc pulley 26 teeth, and my charger reach 13 000 rpm on 6500 rpm engine speed. My rev limit is 7200 rpms and If I rev it on those rpms , chargers spins 14 400 rpms.

I use the 8v tensioner pulley, my belt is less swinging .

That set-up is for 65 mm toothed pulley from all dealer , but if you compare with original 6pk it is even smaller equivalent cca 63.5-64 mm.

 

PS. I made mistake a few post ago, my set-up is 56 crank 28 sc ( a few post ago I wrote 26 for sc , but I use 28 on sc , and calculation was correct for 56/28 )

Ok that makes more sense now. i was looking at older post of when you said you had 56 26 and wasn't adding up.
