Jesus christ...the rest of the stuff seemed within range...but $5,200 for installation labour and tuning?



What in the actual f*ck?

Unless you put in a BOV, yes, off-throttle compressor surge is normal.

This is my car with the same kit.

Anyone have specs on the turbo included in the T518Z setup?


I'm looking for wheel diameters, compressor and turbine A/R ratios.

Wastegate flutter or compressor surge?


My boosted install originally had a TiAL Q50 BOV. It wouldn't blow off quickly enough or at lower pressures so I still had a bit of chirping.

I hear the bov and a flutter

That's a problem. Make your BOV open earlier.

That by a tune or mechanic?

If it's a BOV controlled solely by manifold pressure, I think it would mean adjustment of the BOV itself and perhaps changing the springs in it.


What BOV are you running? My car came with a TiAL Q50, but it wasn't opening fast enough or "blowing off" at lower boost levels. I changed springs to the absolute lightest one that would still keep the valve closed at idle (needed a bit of shimming) but it didn't solve the problem 100%

So- In the end, I went to a Greddy FV style BOV which seemed to be a vastly superior design (response wise) for applications that don't need to support massive levels of airflow.

Hope this helps.

Running tial QR with a 10psi spring so maybe i need a lighter spring

The Q and QR and essentially identical. And my experience with the Q was it could not be made to work in such a low-flow application. According to TiAL tech suppoirt they are designed for 1000-1500HP applications.

They told me flat out it was the wrong BOV for my application. Said to use a QRJ, which is designed for smaller applications like ours. Problem is - the QRJ isn't supported in Canada, so getting replacement springs would take forever.


In the mean time, I checked out a Greddy FV on a friend's car, found it to be a far superior design for my application bought one and never looked back. Just be careful of counterfeits - or if you knowingly buy one make sure it's priced accordingly. If you go the QRJ route, be aware they use a completely different set of springs. And just like in the Q/QR you pick the spring rate according to the amount of vaccuum you pull at idle with all accessories off.


Good luck - hope it all works out for you.

Will swap bov thanks
Will i need a retune?
