does anyone know what the max boost i can run on 440s with a to4 turbo? i'm hoping to hit 18psi, but i don't know if im going to be maxing out my injectors or not.

i ran 18psi daily on mine with 440s and a 60-1 single, afr's stayed in the 11.2-11.7 range the entire time, even took it to 21psi on accident and it still stayed in a good afr range

Actually...
If you're running a stock downpipe, with 20psi...
This would be more likely to cause failing turbos.
When you're running that much boost, restriction is the last thing you want.
(ie. Running a 7M at 20psi on a CT26 with a stock exhaust).
You're choking up those turbos when they really need something well-flowing enough to let out all those exhaust gases.
Very gutsy, though.
Got any numbers?Jeff

Actually if those ceramic babies spins more than it is doing right now they have a greater chance of disintegrateing. I have a 3 inch exhause split to 2 1/2 in the rear with no cats or resonator so im still getting most of the backpressure out at a decent rate ,the other thing that puzzels me is everyone i know with a downpipe blown their twins .I dont have any numbers but when i do get some i will definately post it up .

Lol seriously....But im going by experience .This is my 3rd 1j sc. Its either im just lucky to get perfect engines or its becuase i never had a downpipe. oh well only time will tell.

Ok, most people have been posting the turbos with their pressure. I never check peoples profiles. Sorry.10secdream;1078319 said:
