Could always get a nizpro overboost valve.

I love the way when you put n I a p r o in it autocorrects spelling to nizpro. That's pretty cool.

When are you getting yours tuned? Is it ready for it and who's doing the work?

Mine doesnt run a blow off valve and hasnt for 3 years. Turbo still puffing away all ok. I think with this topic as you say,their is no 100% correct answer. Just what people have heard and their own experience. The turbo could of sh*t itself for any reason and someone will say it was cos no blowoff valve. At the end of the day,most have no problems what so ever without a psshhhhhh valve.

Hi all, there appears to be some evidence that a BOV is benefical to turbo longevity.Blowoff valves are used to prevent compressor surge, a phenomenon that readily occurs when lifting off the throttle of an unvented, turbocharged engine. When the throttle plate on a turbocharged engine closes, the high pressure air in the intake system is trapped by the throttle and a pressure wave is forced back into the compressor. The compressor wheel slows rapidly and may even stall, and the driver will notice a fluttering air sound. The rapid slowing or stalling stresses the turbo and imparts severe turbo lag if the driver accelerates immediately after the surge event. Cheers.

If you don't have a blow-valve and your car is running on a treadmill it won't be able to take off :oops:

...unless you have a turbo timer installed.
