New Supreme Tool, Piston driven exhaust valves

[mtn-doo]

The new Piston driven exhaust Valve from Supreme Tool is finishing testing. They will begin production shortly. They are an all aluminum cylinder with an internal piston that is screwed on the top of the Valve shaft. An internal pressure port accesses the inside of the cylinder below the piston and pushes the piston "up" to open the valves. They are 100% boost proof. No bellows or springs etc. to fail under boost. They also do not require bleeding any pressure from your system which gives you the quick spool-up and throttle response you need.
Mark at Supreme Tool has finished testing on the Cat motors with over 25lbs of boost in race sleds. They have finished testing perfectly in the Cat applications.
I have been testing them for Supreme Tool for a month now on my Turbo Performance XP with the Garrett 2871 turbocharger and 12 to 14 lbs boost, with tremendous results. Give Mark a call at Supreme Tool, or feel free to shoot me any of your questions. Thanks

Sounds cool post some pics when you get a chance

Any pics or more info? Sounds like what we have been needing. The STM valves work great, but can't use them on a turbo. VERY INTERESTED, will call Mark Monday.
