Engine/Transmission (1994 - 1998) Too much boost?

[WMonroe]

How much boost is too much for the stock turbo and headgasket? After installing the #11 and boost elbow I can see about 36 psi of boost. Is this too much?



I will be sliding the #11 all the way forward tomorrow. I set it at the factory position at first just to get a baseline, and it feels slightly more powerful than the stock plate full forward. That will all change tomorrow though. Oo.

Seems to vary between trucks. But anything over 35 psi from the stock turbo is bad news for the turbo.

Thanks for the reply. I kinda thought that I was at or getting close to too much. I guess I just need a bigger turbo.

If you still have the OEM clutch, you may want to wait to slide the plate. It might not take the extra power.

SLIDE IT. If the clutch slips, SLIDE IT BACK. easy.

Slide the plate. If the clutch slips... . get a southbend Con OFE



The stock HX-35 is a stout turbo and is capable of 40+ psi. It isn't very efficient at that pressure and does generate a lot of heat but it will hold it. Wait on a bigger turbo until you have the fuel for it. Save your money, those clutches ain't cheap



You are fine at your current boost level. I know many guys who spin those -35's to 45+ psi. Get some 370's, some delivery valves, more timing, THEN worry about that turbo

I can hit 42-45 with my hx35.
