Anyone ever seen data like this?

 

I remember Robert at FP monitored turbo shaft speeds, and turbine inlet pressures on his personal car when he was developing the Black Turbo. He has some expensive standalone ECU though.

 

Sigh you would think this is the single most important feature of a valve.... Agree or disagree?

Second to leaking at wot..i did just assume that they never leak?!!!!!? Rofl

 

What BOV do u have on there?

 

For a quick comparative test u can always remove the BOV/DV and plug the openings in the pipes etc. or disable by flipping the DV.

Are you wondering as set up, at what PSI the valve is actual cracking and lifting?

 

No wondering how much speed drops once you lift. But you bring up valid points too.

Better answer is to lose less speed.

I run a type s with single spring
