Tial QR50

I heard on the grapevine (just one person's knowledge I'm afraid) that TTS were swapping to a Tial BOV for their kit.

I've also gone for the Turbosmart 50mm raceport.

Due to land here today all being well. Got mine through SAS Auto Customs. Cheapest by far

Just fitted the Turbosmart 32mm Dual Port, straight on to the 25mm boss, configured to vent to atmosphere (one out of the two trumpets). It's noisy, but it works! No flutter at all, even at high revs when slamming the throttle shut. So the flow restriction was obviously the internals of the old Sytec 25mm BOV, rather than the 25mm BOV inlet port. This is good news, as it means I won't have to get a different sized boss welded on to the intake pipe.

See the photo below for a comparison. It's quite a lot bigger, and rests on the aircon pipe, unfortunately, despite cutting the joining hose shorter. I'll probably order an elbow so it fits better.

Next job is to fit the recirc outlet in place of the trumpet, with a long hose attached (but not recirculating) to see if it dampens the noise sufficiently. If not, then I'll add a boss to recirculate to the SC intake elbow, I think.

Thanks for updating on this. And glad you sorted the fluttering out. Looks like I will be ordering the same as you

If you definitely want to recirc, you might get away with the cheaper kompact recirc valve. 34mm I think, in that one.

Will have a look. Cheers for help Chris

They weren't the speediest, but were helpful.
