66/14 boost?
 

what are yall crankin the boost up to with a htt prostreet 66/14 with 12mm arp's and scheid valve springs? Nothing else done to the head. I was thinking 55lbs. does this sound right? Im running pretty hot right now and want all I can get to help before water. Thanks[coffee]

bump.............

I'm getting 52psi outgha my 64-13 but I turned my gate down to 47 or so (no studs). A friend of mine is getting around 60 with his 66-14 on a isb. Belive it or not he put a boost elbow on and it realy helped with is temps. He is also running mach 7's

You can run 55 if you got the fuel but IMO that is gettin off the map and not really helpin your situation. Boost is a messure of restriction and more boost aint always a good thing. Do some testin at 45, 50, and 55. I THINK for that turbo 50 is probably just about right.

Call HTT and ask them what is ideal, not what it will handle but what is the optimum boost range for that turbo.

FWIW, I am still runnin my SPS 66 (wich is a 66/14) at 47-48 lbs of boost.

yeah I'll call htt. It's not easy to adjust the boost though. It's really hard to get to it. Thanks for the replies

I dont know about the HTT but on my II it isnt too bad, it may help to pull the inner fender well, I think it is 8 8mm screw/bolt/thingies

k thanks bud
