do i need custom belt for iraggi overdrive pulley?

[Lil Poot 5,000+ posts]

i've got an iraggi 240 amp amputator with the smaller overdrive pulley. measured it with my caliper and its a half inch smaller diameter than stock. says in the instructions to use a belt half the difference smaller, so i went to advance auto and asked for a belt 1/4 inch shorter than my stock belt, they tell me they only come in 1/2 inch increments.

so i get 1/2 inch shorter than stock, put it on, start the truck, smell something, smelled sort of electrical so i thought maybe it was just the new alternator, took my eyes off it for 2 seconds to check the voltage hear a loud ting and shut it off. my serpetine tensioner was pulled so tight, it was sitting at an angle, the bearing heated up enough the thing came right off. i have no idea where the bolt went.

i ran up to the junkyard and got 2 spare tensioners real quick. but what do i do about the belt? the stock one is going to be way too long right? i haven't tried it but i seriously doubt it'll work. do i have to get a custom belt made?

my belt squeals for a second with the iraggi pulley, but then it stops.

i went a 1/2 smaller with no problems

just make sure your tesioner isn't pulled all the way tight.. if you have a tensioner

its not a manual tensioner, its automatic. i dont think theres any way i can make it go a bit looser. really sucks because i have to drive about 250 miles tomorrow, i may just put the stock pulley on the iraggi for now.

Put the stock belt on, see if it works...

If not, put the stock alt in and figure something else out after your road trip...

Indeed.

Try to put a smaller belt on... if it doesn't fit.. take it back.

the 1/2 inch smaller belt was the one i had on when it burned up the bearings. going to try out the stock one after i finish eating, will post back then.

bah... stock belt worked just fine. seems looser than it was with the stock alt, but it isnt squealing or anything. about to take it for a long drive, make sure its cool for the road tomorrow. appreciate the replies.

ya, mines a bit too tight with my new pulley, but it's at least 4 hours of work to get my car apart enough to put the stock one back on, so i'll deal with a quick screech at startup
