On a stock evo 8? bout 5.32 psi on the stock turboe

The factory runs bout 19 psi but thats pushing the stock turbos ability so its just pushing out hot air. So if you turn the boost down to about 5.32 psi ull get those millions of horse powerz LOL

 

i feel u can 400 hp from ur stock turbo with out meth if properly tune and a good intercooler.

 

To the OP, good tune and supporting mods, around 400.

 

Depending on the amount of plutonium, all the way back to 1955.

 

i will pm you all the information

 

ok then bro thanks

 

I think I saw the 522 was the record on the stock turbo. I don't know how... But it must have been a 12.5:1 compression.

 

Wow. Do you know how much torque it was making?

 

The stock 9 turbo is pretty good, but it doesn't hold boost all the way through the powerband.. Meaning boost falls off on top.
