Hi Everyone!,
This is my first time here. I have a question on how tight to torque the serpentine belt to.
I have a 7" crank and a 2.95" blower pulley and it would always slip. The most tension I tried was 70 ft lbs. I just put on a 3.33" and 45lbs of tension and no slip but only 6lbs of boost. I called Reichard racing and talked to the owner and he said that 70ft lbs was not excessive....... I am concerned tightening it that tight. I found on the ASP website that they recommend 65ft lbs on their COG systems, so I guess 70ft lbs on a serpentine is ok???
I'm going to try a 3" Reichard racing pulley and see what kind of boost I get, and hopefully it will not slip!!
How tight do you guy's run?? Has anyone seen main bearing wear with too tight a belt? If so how tight was your belt?
Thanks everyone!! You guy's can see my car in last Nov issue of 5.0 Magazine. The red S351 Saleen. I'm making around 570rwhp with the slipping belt! I was getting 6lbs at around 4250rpm then it would start slipping.
