What is the maximum boost a 15g turbo will produce with appropriate mods???
i used to run 20.8psi from mine, but the turbo is well out of its efficient boost levels running that high. 15-16psi is about as good as you can expect from it
30psi is fine

I used to run mine at 18 PSI and had no problems and will be running the same again in the new car.
i would go for 18psi for longivity of turbo and other bits, but upto 20-21 acceptable, or just push the right foot pedal a little harder :-)
I would change the turbo for a more efficient item if you want high boost numbers. They are really inefficient when out of their respective efficiency island if you take a look at their compressor efficiency maps. Really much beyond 18psi is not worth it from a 15g even with extensive cooling mods and WI.
Out of interest, what's the maximum (efficient) boost on an 18T Alan? Around 1.7bar?
Cheers Frankie, my guess wasn't too far out then.

This is a compressor map for the 18t.

This is the efficiency map for a 15g.
No need to be so smug about it ;) I'm getting this below...
must be cos I'm foreign lol
