How much boost can be run on a stock k20?

 

29psi, dyno proven

 

Freddy is correct, look on youtube for k20 hatch. Its gold?yellow and they try to run 40 but it blows

 

opps, 41psi, my bad

That motor was blown during that test run, bud.

 

The car was running 20 or so psi and they tried to run 42 and it spiked at 41.somthing and blew

The story went, they were running at 20lbs, then they wanted to adjust for 38lbs, and it spiked at 41lbs and the engine was toast.

 

pwned

 

 

so which k20 can run 29psi stock?

Yes, it was a K20A2.

 

You guys do realize these quoted psi numbers mean nothing correct?

You can be saying that you can run 29psi on a stock motor and some idiot is going to strap on a GT47 and blow his motor.

The larger the turbo, the more CFM's it flows versus a smaller turbo at the same psi, which makes a vague boost pressure guide to engine durability a horrible idea.

Judging volumetric air displacement = better idea

You have to remember that regardless of the airflow in the charge tubing, the intake manifold should flow at relatively the same rate, given the constant in the equation (aka. the PSI).

 

so when u say stock d17 can hold 27psi does that mean daily driver and all?

Who said a stock D17 could hold 27psi? That's not the slightest bit true.

 

so how much can it really hold stock then?
the most common psi for em2 i see is 14psi. can you go higher on a stock engine?

With a stock intake manifold, the highest you'll get is 9psi. With a modified Y8 manifold, maybe you'll see 12.

my buddy's boosting ~10psi on a t25 stock mani doing fine... (i think)

 

Hahahaha this thread just got so funny.
