head bolts

how far(what psi) have turbo guys taken head bolts before lifting the heads? Been running 17psi on my twinchg setup for a bit now with no issues. Ran the car with 15-16 on a 2.6 pulley for over 1.5 yrs pre-twin, without issue.
Thanks for any input.
 


Depending on who you talk to it seems the limits that most people push them are right around 18psi. Most people that have a build pushing up there already have ARP head studs.

Let us know when you find the limit ;)
 
lol yeah, i would be lying if i said i wasnt a little nervous. The studs are sittin in my shop ready for install. i just couldnt bring myself to tear it apart to install them prior to the twin setup. maybe ill turn that boost controller down..... ;)

also, people seem to always seem to talk bad about the mls gaskets, but they have been on my car for, i think 4 years now, holding strong. i dunno

Sounds like you both should. Heck.. you could egg on the tow truck guys to race once they pick ya up.

Dan, I think most of the bad talk about MLS come from guys installing them improperly. There's a few different ideas abot how best to install them. Also new/used may make a difference.

I wouldnt expect factory stock headbolts to show issues at any 'boost level' I would look more at horsepower and timing to determine what the head bolts will handle.
