qwick questions guys and girls what sort of boost can a standard g40 lump withstand???25 psi 30 psi any ideas?

it will cost you to find out if someone hasnt had the misfortune already 

Factors such as the engine condition and the efficiency of the overall set-up will come in to it, one engine might live for 20k with 20psi, another might only manage 10k. A k03 turbo runs out of puff at anything over low 20's psi from what ive read anyway. Even a roller ball bearing GT25 is listed for 22psi maximum!?

If you find out post up the pics though, will be interesting to see!
