Hi guys,

I'm doung eaton swap to my mm 2004

it's all done but there is a problem with the belt size foe supercharger

I don't know the size for the pully (there is no written on it) but the kit comes also with 3.100 pully

i try to fit gates k 080537 it's small

I search for something about cobra kit then i found this thread on the net

http://svtgarage.com/showthread.php?240-03-04-Cobra-Eaton-M112-Tork-Tech-Terminator-Install-4-6-SOHC-2-valve/page7

he said biger than 3.100 should take gates k080550 even size was 3.4 or 3.65

i try to fit gates k 080550 it's fit yes. but not very tighten as it should:alone:

now I don't know what should I do?? I need to chack if k080545 works well or not but
on the thread there thay said 3.100 will fit gates k080545
also this size not available in saudi arabia so when i buy it it'll cost alot on shipping without Returns the amount:bigcry:

soo I think for 2 idea

first: to change the pully to 3.100 beacause i had belt for it but i afraid the boost will be high and my car is stoke.

so advise me is there any problem with change the bully to 3.100 and how many psi of boost will be???

secound: I don't know if someone here worked with gates k080550.
also is it ok to run the car with this belt ? I mean if it's not very very tight

here is photo for the pully3.100 and the other

I have question how many psi of boost i can run my car with?





I appreciate your help all.:bows:

Has 3.1 upper and #2 lower. The pulley on it already is the stock pulley and needs to come off . The belts go to the 3.1 pulley. It's fine, same pulley setup as impalaslayer and Zach said its fine also for boost

I'm looking for the stock size lower pulley..When you take it off to put the 2lb on,I'll buy it from you..
