Vortech supercharger install, stock belt is a no go!!!! DAMMIT!!

[1993SSP]

Bought a new stock length belt to go along with my install, it wont fit, anyone else have to run a different length belt with their install??? My car has a/c ,power steering and im running a smog pump eliminator along with a higher amp alternator from a 2000 V6 mustang, could there be a slight difference in the alternator pulley size thats causing me a problem? The belt size have is a 5060905, I tried an 5060915 I had and it's way too long! The 905 belt is almost long enough but it would have to be pried onto the last pulley, not a big fan of prying on belts

Sounds dumb but make sure you are routing it correctly. With factory a/c it should be a 90.5" belt.

It's routed correctly. I have followed everything to the exact details. I was wondering if there was a different size between the alternator pulley from what was on it stock and the newer 2000 model one I have on the car???

 

[1993SSP]

Figured it out, the newer model alternator is a little over 1/4 inch bigger in diameter!

Congrats!

See if they have a 5060910 belt -- it'll be right in between the other two.

You should compare the belt you took off with the new one. More often than not, the replacement belts are short. You can try to strecth the belt if it's close.... Put it under feet and pull up with your arms. But that is only if the belt is close to fitting. If it's way off, go back and ask for a different brand belt.

I think the vortech crank pulley is also a little thicker, mine was at least.

Take a peice of string, rout it around everything correctly, pull it tight then measure the length of the string. Thats your new belt length. Thats exactly what I did, then I went down to advance auto and picked up the belt. Have fun

I got the 910 belt, I'll try gettin it on tommorrow! I cant wait to hear this supercharger and feel how it is powerwise. Can any of you go into detail on the supercharger tensioner, Im a little confused on how it all goes on, a pic would be helpful!

what's confusing about it? You just bolt it on and make sure its lined up straight. You might need to use some washers to even it up.

Yep its very simple. I think I have 2 washers between the bracket and pulley.

 

[1993SSP]

hrmmm ok, which of the 2 round holes near the elongated slotted hole do you place the pulley???

 

[Rick 91GT]

You can use either of the holes in the bracket for the pulley...it allows adjustment.
