What kind of pressures can you push through a factory first gen turbo before it gets to stressful on the turbo?

 

Well, they say 18 - 24 psi for the old H1C. I might be crazy, but i get to almost 30 psi with mine if i get on it.

 

ive seen 32 turbo screaming oh gotta love that sound

 

 

im at 25 now....wonder what the new 5x.014's will do to her?

 

before the intercooler and the 60mm upgrade wheel i could just get 30, after the 60mm upgrade wheel i was pushen 45, now with the intercooler all i can get is 37, but the truck runs a heck of a lot better at 37 with the intercooler then 45 without it

 

That's some intense boost pressures through a first gen. how far can you crank the full power screw in before you approach runaway?

 

Different on every pump. Some bottom it out, some get only a couple turns. Go 1/2 a turn at a time, make sure your turbo inlet is un covered, and have a buddy stand by with a 2x6. After every 1/2 turn, snap the throttle to wide open and if it starts to run away get the 2.6 over the turbo inlet.

 

That's what i did the first time. Had the air cleaner tube off with a 2x8 ready to slap over it, but i only went about 1/2 a turn because all the places that i looked said it would runaway if you went much more than that.

 

Mine is not fully bottomed out. It is all the way in then backed out 5/8ths a turn. I have hit 27lbs before aswell.
