are they any sets of underdrive pulleys that come with the right size belt for the 3.4.....??? and what brand of pulleys are you guys using....

thanks....

also I think lmperformance or Tybryne motorsports may have them. I am not to sure about that and maybe Thundermotorsports.com

these were the cheapest.

 

i checked out the asp's at tbyrne.....and those are cheaper than the ones i was originally going to get from jet performance....looking like i'll get the 541801 from tbyrne, does anybody what size belt i should get? i really don't want to have to buy/return belts 5 times to get the right one

the asp's are on this page....

Don't order the belt from T-Byrne, they'll send you a 755 length belt and say that it will fit, but it will only fit if you only swap out the crank pulley.

If you're swapping both, like I did, a 770 size belt will be perfect. I can run my air conditioning at full blast with no belt noise.

Trust me, I went through that experience of trying 5 different belts!

 

thank you muchly for the info man

 

also....looking at the jet performance page....the picture of their pulley's shows that it comes with 3 pulley's.....and in the ASP picture it shows 4 pulley's....just curious as to what each 3 and 4 go to respectively....

 

what areas improve with the addition of the pulley's....i'm gonna go with the crank and alt pulley set....low end/top end?? thanks....

 

With the pulleys, you should see improvement throughout the rev range. Basically, turn your A/C on and go half throttle. Then, turn it off and go half throttle. That's something like the difference that you'll see.

Good luck with the install! The crank pulley isn't too hard, but you'll have a tough time with the alt. one.

 

got this swap done today....it's a decent difference....worth the $65 think i might wait till spring to do the new gears and lsd....winters can get bad here, and the added power may get me in trouble shift kit goes in tomorrow....

neither pulley was hard to get off....uncle got out the air socket, and everything was a breeze he may love mustangs....but i love that garage....can't hold it against him

 

755 you said was the size if you only change the UD pulley..which i plan on doing....where is that? i cant find it.... and about how much smaller is it thant he belt i have now? cus i got hte pulleys..just need the belt.

 

i'm actually using the 770....i got it at Advanced auto for $23....ASP recommended getting the 760, so just for giggles i tried that....didn't come close to fitting....so in the mean time, i just threw the stock 775 back on there...till i could get back to AA and picked up the 770....needed a new one anyways...

 

thats cool..but since i am only changing the underdrive..and not the alt. one...or any other.....where can i get that belt 755 like someone said earlier? cus that is one i need i suppose..can i just go to like a local pep boys/ or auto zone??

 

yep, i got one at advanced auto....your pulley should come with a sheet that has the model number of the belt....or you can just ask for a 75.5" belt....
