ok, i have been searcing for this for a millon years now. it is driving me insane. i am looking for the right belt length to run the belt in a v-pattern like speedy02. here is the link for the picture of how i want to run it. https://www.performancetrucks.net/fo...ght=short+belt the problem is, i only have the underdrive pulley, i am still running the stock alternator pulley. if anyone has this, it will be wonderful if you share

 

anyone?????

 

I would also like to know..maybe someone has the part number to a set up like that but bypasses the alternator too??

 

here's what i'm running right now.
68", 6 ribs.


for stock crank pulley bypassing alt & p/s is 60" x 6 ribs
for asp crank pulley bypassing alt & p/s is 55" x 6 ribs

 

How much of a gain is bypassing the power-steering worth? 10rwhp/.10 of a second?

 

the last time i dyno'd my truck i made a total of 3 pulls.

the first two was with the factor belt, driving all the accessories and both put down 330/330.

on the last pull i did the short belt, bypassing the alternator and p/s and it put down 340/340 just like that. oh and this was with the stock crank pulley too.

 

that is with the stock alt. pulley right?

 

correct.

 

thank you sir
