I managed to find the head bolt torque specs for the ARP bolts and studs from Feuling, which are 10,20,25,30 and a final torque of 35ft lbs, I also have the stock harley bolts and studs torque specs of 15-17 ft lbs final torque but I cant find the specs on the SE bolts and studs..... I am putting one of these into my 09 turboed SG... thanks for any help.... Jody
i always use the sheet out of the cometic gasket package. would need to dig it up for you. regardless of what bolts i'm using. i run the se studs in my superglide, stock in the bagger.
I would call Frank @ Dragos bike works and ask him. He specializes in turbo and supercharger systems for Harley engine >> http://www.dragosbikeworks.com/
thanks, my bottom end is at Darkhorse now, just gattering a few last parts before its back here next week.... I am using the Cometic gaskets and will probably go with the ARP studs/bolts... but I see alot of guys on here using the stock ones or the SE ones, big savings there... we pushed this bike to 160hp on stock components, I rode it for 2000miles then the head gasket let go, I knew it would. Now I am building the motor like it should be, then we push it to 200hp and tune it back down to 160hp for dailly riding...
so what guys on here are saying is that which ever bolts and studs they use with cometic gaskets, they torque them with the high torque values from cometic, not the lower ones from harley or SE... ????
I'd probably pass on the SE studs and go with the ARP. With a FI engine... these would NOT be something to scrimp upon... know what I mean? Somewhere in the back of my brain, i seem to remember the SEs are brittle, but can't swear to it. I'd go stock before SE if it were me.
What CR are you setting at and how much boost? Just curious is all.
i am using JE 9.3:1 compression , I ran up to 14psi boost last year on the stock motor , and took out the head gasket after 2000miles or so, we knew it would not last but wanted to see how long with that much boost... will run the same or a little more this time around, but with a built motor...
I talked to the guys at Trask today and the ARP studs and bolts are the way to go.....thanks to all, I will keep updating my build post on the "performance fuel systems" heading...
