I stop at 30psi myself, I'm a chicken with stock head gaskets that I really don't wanna change out anytime soon. I have had it up to 35psi a few times and never have topped it out so I don't know where it would stop at. I can hit 25psi in a few seconds and still not even feel like the turbo is spooled.

 

i run 100hp injectors, and with everything in my sig, it takes A LOT to hit 1500 degrees on the pyro. thats with the stock turbo.

steeldragon, i sent you a pm about my injectors.

with just an edge comp you can expect to see 40psi...i have had my comp for 3 years and never had any problems with head gaskets. (knock on wood)

now that im ready for some 150+hp injectors and big single, the head and head gasket is an area of concern.

 

With my setup, I get about the same heat as with the small turbo and 275's. Just takes me a little longer to get there now, but not much.
the 275's have 5 holes, the DDP 95 HP injectors have 8 holes.

Coon, what kind of injectors do you have?

 

ddp 3's

 

Roger.
I can hit 38 psi in about 1 second with that Comp.

 

I have had the 62/12 as a single, running bully dog crazy larry stacked with van aaken, mad 432 at rear wheels, but when pulling it would still run hot pulling a long grade it would hit 1400* no problem even with the fuel cut off. a good exhaust, intercooler, and then a turbo helps drop temps. I am running it compounded with HTB3 5 in exhaust, Bd intercooler and pulling heavy still hit high temps with the tst box on.

 

I made 507 and 1094 on a 62/12 so they will make great power but it can get hot quick if you let it. with the same sig as i have now except Rv 275's and the stock HY I made 377 and 810
