how much boost can you run without blowing the stock headgasket or streaching
the stock headbolts? chime up if you are running meth/water injection and higher boost on your car. make sure to list your injection kit, boost pressure, and how long or how many miles you have driven it WITHOUT failure.

 

28 psi and stress starts

 

^ yup.. def by 30psi

 

does it really matter? kinda like how fast can regular rated tires can run without exploading
if your upping the boost more that 22. just get upgrades to make sure you can handle it.

but if you wanna test it out im all ears on how much it takes.

 

34 pounds, stock head studs... no problems....


its hard to stretch them with the stock turbo...

 

34lbs/stock turbo, why?

 

I have been running 30psi for 6 months

 

 

are you constantly hitting 30psi

 

455wtrq spike... 430whp... should do 123-124 traps =-)


just screwed my mbc all the way down... hold 25.5 pounds to 7600

 

That's on stock turbo?

 

 

I tested stock head bolts on dyno to 560hp/511tq. 2.3 35r 30psi. They hold LOTS of power. They are a waste of money on anything under 500 ft/lbs torque.

 

I only pulled that power on a stock turbo with a stroker engine.

 

I spiked 28psi on the stock turbo for a long time while on the stock headstuds, now I'm running 30-31psi on the Green.
