are all the eaton superchargers have the same pulley connection

[kazkillinger]

for instance can i use a pulley from a cobra a 3.15 they have eatons right.

As far as I know, the cobra has a Paxton super charger, and it is not a press on pulle.

I'm pretty sure the Cobra uses a M112.

YEP IT HAS 6 RIBS , NOW THE STOCK PULLEY ON THE GTP IS 3.5 SO THEIR IS A DIFFERANCE IN PULLEY SIZES BUT THE SPINDLES ON THE EATONS ARE THE SAME SIZE SO YOU COULD USE AN AFTERMARKET PULLEY FOR THE GTP
YOU JUST MIGHT NOT GET THE PSI GAINS THEY CLAIM

ahh i see so if they have a 3.10 and saying 6 lbs its really four for us?

yep, you're right. However, the paxton was installed on some aftermarket factory upgraded cobra's. It was a special order or special dealer option on some of the 1990 time frame models.

A 3.1 PULLEY ON MY RL WOULD HIT 14 PSI AT APPX 4000RPM & GO SLIGHTLY OVER AT 6300RPMS SO THATS A FIRM 2PSI OVER STOCK
