as title states...how much boost can they handle before boom?

probably not much more to be gained past 21psi

thanks.

stace would think otherwise tho

Stace was running 24 psi on one I believe.

What's your application for this turbo, may assist in providing a more accurate indicative boost level.

All depends what you have to support it. Winding the boost up without changing anything else is only beneficial to a certain point, after that its just hot air.

ok, at the moment, 3" TBE, CAI, unichipped with boost modual......saving up for eboost 2. everyday driver and at the moment running 18psi day in day out, which im over big time...i plan on getting the eboost 2 so i can turn boost back to stock for everyday driving, then go to the track and set it back to 18 psi. what my origional question was meant to say was: is running 18 psi dayin day out bad for turbo and engine? and when i get eboost 2 whats a good psi setting for dragging?

As long as the tune suits it, 18 is fine.

What's an 'e-boost' set u back? May be worth while saving up, flog off the unichip and look at 2nd hand ecu.

$700 give or take for eboost 2.
