How Much Boost On A Stock 34 Turbo?

[rad s15]

hi guys, quick question,how much boost can a standard r34 turbo safely run.

any help appreciated

[Strik3r]

the rule of thumb is less than 1 bar (~14psi) but this probably wouldnt be healthy for extended periods of time.

If your going to use a boost controller you could run 0.5 bar (8psi) all the time and then flick to ~0.9 bar when you need that extra grunt.

i think bass junkys died at 12psi

Mines been on 14 psi for about 3 months, i was told that's about highest to go before you start cutting into turbo life dramatically

[paulr33]

r32 @ 14psi != r34 neo @ 14psi

the engines will flow diferent exhaust gas, temperatures and state of tune will affect it. so an rb20 with a er34 turbine at 14psi probably wont fail

12psi is probably more sensible then on a rb25, swear i read that the guy at the top had a rb20 in his s14 (although i also swear they have sr20's in them and i dunno why anyone would downgrade lol) man im tripping today, guess thats what happens when u sit on the pc all day coz ur line has a cracked windshield -_-
