What psi?

[Shingler4596]

Would 10psi of boost be too much for stock internals?
What boost would you recommend for a 1.3
It's on a TD04 turbo

the pistons are the weak link shingler

 

[Shingler4596]

I figured as much... fingers crossed sometime in the near future I will have a forged engine for it but just need to know what PSI would be OK to run...

 

[frank]

probably 5psi on the stock ecu, or 12psi if mapped

 

[Shingler4596]

I'm on micro squirt so it's fully mapped ... so 10 PSI should be safe if mapped correctly? I'm going by 10 as that's about the stock wastegate on my td04

 

[frank]

yes paul (pollyp) ran 10 psi for a while, with a nistune remap

I ran 12psi using a vl37 no problems. Sometimes the turbo would boost upto 15psi on an incline and no issues. Now I’m running a gt2554 at 9psi and all good. Mapped by fusion motorsport

So stock ecu will take 5psi without anything
