N/A PSI rates
With an s4 turbo charger and n/a motor. How many PSI would this engine be able to handle?
I've tried searching...Come up with 10
Anyone?
thanks

10 safely with the stock fuel and everything... are you talking about how much the seals can hold? i read someone running around 700hp with the stock 2mm seals.. thats all just about tuneing.. and i think the stock S4 turbo is good till i think around 13psi then it starts to crap out... if your doing the j-spec sway and keeping it stockish for awhile look for the S5 turbo and manafold

The stock s4 fuel system will crap out on you long before you can get 10psi anywhere above 6K. My fuel pump runs out of volume at 8300rpm and I'm still n/a....

theres no way the stock fuel system is going to keep up with 10 psi. I was reading about a guy that was supercharging and had bigger injecters (550cc?) and a fuel pump and he still out ran the fuel system on his na engine. He was pushing 10psi.

The engine will handle whatever you want it to handle...the question is, for how long? I personally wouldn't go past 14 PSI (stock turbo) on the NA block. Fuel upgrades are a given.
