Lightbulb What wastegates you big hp guys running?

Looks like my ebay/knockoff of the hks 60mm vband gate has reached it's limit. It worked fine when i was running 10psi on the street and 18 on the track. But now since I've got a better microtech I want to be able to run 25-30 track and 15 street...

I got the 60mm gate to do 25psi on the dyno the other night, but that was with the adjustment bolt all the way in, so I've got it stuck at 25psi and no street lower pressure...

I was leaning towards turbosmart or tial. Any suggestions?

Jason

A low cost wastegate that's getting good results is the X02 60mm, or you can spend a little extra and go with a bad *** JGS unit.

My buddy just picked up a Synapse Eng. Synchonic 50mm gate for his GT42R-fed Honder. Very nice! Just over 400 shipped from Rx7store.com.

Ive got a 38mm Tial with a t04b v1v2 compressor. Got a manual bleed valve set at 8psi and a 7 pound wg spring. She hits 16.5psi priefly and then settles to 15.5 by redline.

PM me for details on the bleeder valve tied to the top wg port.
