Boosted Performance single turbo build

Boosted Performance

I can't hear the audio...the links want me to pay for it for some reason...Anyway, I will check the spring once the car is ready for tuning. It may be too stiff, and the waste gate is fluttering.

Will have to also drill and tap the IM so the BOV has it's own dedicated vacuum source. Since I did not have a base map on hand, the stock injectors were left in place and the IM did not have to be removed. So it was never drilled/tapped for the BOV vacuum source.

I have had my kit on my own car for 4 years now, and there is a bit of flutter only on light acceleration between shifts. With 25,000 miles on the system there is no issue to date. The only thing that would be of concern is compressor surge while in boost. A softer spring could also be beneficial...but it is hard to say without knowing the exact vacuum at idle while the engine is warm.

Either way, nothing to worry about.

I might turbo the Z at some point, hoping this option works for people...

Eto Kurto!!

Thanks Nix,

I love it, very deep down low and winds out nicely, not to loud at idle just a deep rumble. Cant wait to hear what it sounds like under a WOT shift.

Sent a PM a while back. Lost a lot of my mail. Is that jig ready for the stock type exhausts?

Boosted Performance

Never got a PM regarding that...but yes, the stock exhaust hook-up is now available.

Resent. When will you start your line with those?

Boosted Performance

That is a simple change, and it is available now. The entire kit stays the same, including the first down pipe that attaches to the turbine housing, as well as the recirc pipse. Insted of the Y-section that comes with/for the F.I exhaust you get a sinle 3" pipe.

on the flutter sound, or compressor surge.. whatever u wanna call it, people can only theorize that this is bad... however, u will NEVER find a case of a turbo failing because of it. slowing down the turbo doesn't hurt anything any more than coming out of boost does...

if someone can find a case of that causing turbo failure, i will eat my own hand

Through my research after this was pointed out it seems that a bit of flutter is ok. Its when you get to much of a delay in the valve opening do you really start to stress the turbo. Its the fact that the boost is very low when the flutter occurs, under high boost I think you would have some issues.

This is very true, and only happens during light decelerations. If you were to go WOT and shift you would not have this at all. Light decel will cause the flutter because you are not going to deep vacuum and the BOV does not open up right away. I have driven a few TT Z's as well, and can duplicate the sound in the audio clip heard here.

Correct as well. In order to have the BOV open fully the spring has to be overcome. If the spring is rated to at -18hg, and you shift at -10hg, there will be some flutter, naturally since the BOV did not open right fully.
