Im finally going to break down and get my lazy a** out in the driveway this weekend and put my arp studs in, the instructions say torque to 95ftlbs with their molylube, but the stock bolts are at 110... I have done my research on previous posts and it seems 125ftlbs is what most are doing, does that sound about right???? Hope it doesnt rain, this no garage for the truck thing sucks...

 

90psi to start then do a heat cycle on them and retorque to 125psi is what we do here.

 

Thanks Pat, will do. The heat cycle will be interesting since I am outside and it is only 50 degrees F for a high and at night it is getting below freezing. I guess I will have to put the valve cover on button it all up and run it with the high idle, otherwise it will take forever to reach operating temp.

By the way I love my BD twins... Cant wait to spool them after cam install.

 

I do 125... Go through several heat cycles with no added power. Then break each one individually and retorque to 125

Pat, How is the s300/s400 twin set coming along?
