Max Safe boost on stock motor

[cchase]

i make my turbo out at like 32 lol, but ive got sticks and turbo and no studs with the most custom programing you can get, you'll be fine, all though my next step is studs so i can run compound turbos

I run a 10K mod, but what is the advantage of the 5.6K version?

Since ive put my gauges in ive seen 19-20 psi on stock and 26 turning up the bully dog. Not very much i guess. Oh and ive got a AFE stage 2 intake. Does that sound about right?

So whats the 10k mod? or 5.6k?

There are pics somewhere around the internet. That was Cale that did that. I have it on good authority that the block was already cracked when he split the block.

As far as the original question, good luck on blowing the head gaskets. You can go above 40psi without too many issues, but it all depends on your tuning. It isn't the boost psi (per se) that that will give you issues, it's timing and cylinder pressures that cause the most problems.

My vote? You'll window the block from a busted rod before you lose a head gasket. Or chew up a piston or two...

30 psi with my mods. no problems so far

i can hit about 28-30lbs with my DP. my cousin used to be able to hit 45-50 in his truck. but he has stage II's and jody's aggresive tune. you'll be happy with the DP they're great tunes.

I've hit 34 a few times with the H2E and stock sticks in the 120 setting. It makes me nervous to push it that hard without studs. I'll be studding it while I've got it apart for the big injector install.

If you push the stock turbo past 25psi on a reg basis you won't have it for long!! I have been around these things to long to be told otherwise!! Some of these boost numbers seem way high with no real tuning, but that's all I am going to say about that!!

Could the gauge be off?
