  1. great idea!

     

     

    ATPturbo already released this a few years back though =(

    The VES system is a system that works “on demand” at the onset of boost on turbo and supercharged vehicles to free up all the backpressure (just as a large exhaust system would) in the exhaust stream so the engine can make maximum power. The VES system works as an active dump tube that completely bypasses the restrictive exhaust system when boost is present. As soon as the turbo spools, the valve begins to open. By the time the turbo makes full boost, the valve is fully open.

     

    Highlights of the way VES works:

     

    * Completely quiet and stock-like sounding during startup, idle, and cruising.

    * 0 delay in valve response to boost, yet very smooth transition into boost mode.

    * Automatic open/close under boost using existing boost source on turbo engine and does not rely on wing nuts or electrical motors.

    * Integrate a boost controller to control when the valve opens or completely turn it off.

    * Addresses virtually all complaints associated with large 3” cat-back exhaust systems.

     

    Highlights of how our VES components are built:

     

    * Solid billet steel construction holds up to high (turbo) temps and won’t fatigue and fail in continuous heat.

    * Precision CNC machined to tighter tolerances for a gasket-less seal.

    * Built using existing, reliable wastegating technology.

    * Standard valve built to accept most common actuator bolt patterns for wide range of spring pressures.

     

     

  2. umm.. im running a .488 lift and 260 duration (in/ex) cam on my car..

     

    Phil we have very very similar specs.. and I also have a 2mm metal headgasket...

     

    I didnt need to adjust the cam sprocket at all.. only thing I did was slide in the new cam, new springs and adjusted properly.. and changed some tuning.

     

    I didnt even bother changing the timing.. and I have great power and the turbo gets full boost at 3,600 RPM. Maybe the altitude makes a difference on spool or something.. but I love my setup right now.

  3. I've narrowed down where the noise is coming from..

     

    Somewhere in the area of Cylinder 1, the thermostat and the distributer.

     

    Now the noise is a squeeling noise(letting air out of a balloon with a pinched valve) and is related to only vacuum. The greater the vacuum, the louder and higher pitched the noise is. Also.. this will only make the noise when HOT. the engine will not do this cold or warm.. only fully warmed up or hot.

     

    Could this be a thermostat??
