Enter the VES (Virtual Exhaust System)…….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.

That looks like it is pretty much a wastegate that vents into the atmosphere.

Like the old school exhaust cutouts... I like the concept but on a rotary? Can it be tuned to only open at certain levels of boost or is it like a light switch, boost at all and it opens up? I have driven a 12a running straight out of an open header and will never do it again without ear plugs. Dont most tracks anymore have rules enforcing at least some sort of muffler?
Im thinking on the street it would be fun untill ya get caught using it, and on any kind of ported engine im sure it would cause internal ear damage very quickly. I think on a boosted boinger it could be cool.

Any dyno numbers or any backing supporting how this increases horsepower??

SnowmanSteiner

Any wastegate that is vented into the open atmosphere is doing the same thing. This is only useful if you are running an internal wastegate. If you have an external wastegate you just have to remove the pipes going back to the exhaust and get a new dp made without the pipes to recirculate the wastegate.

Its not a wg, its a exhaust cut out except its pressure activated instead of user switch activated like most of them are. I've been looking for one of these, as a matter of fact I've been thinking of making my own. Since the last sentance says "Standard valve built to accept most common actuator bolt patterns for wide range of spring pressures" then you can swap the actuator and have it open up at different boost levels. I really want one of these, I'll set it up to open at 16psi. What I want to do is normally run 14psi and the cut out doesnt open which makes the car nice and quiet with my restrictive RB exhaust. Then have a high boost setting of 17-18psi and when I run that the cutout would open, at that point its like barely having exhaust at all. I wanted to install one at the end of the dp but that would depend on what temperature that thing is good for.

Where did you find it? Do they have anymore information like what type and thickness steel it is? What temp its good till?

How much is it???

Good find man,

I've seen this idea before but not one that is + pressure activated. The ones that are push button activate are better imo.

SPOautos

The electrical push button ones are slower, they dont open very quick. If you want to be able to turn it on and off then you could still use the actutor type but put a home depot valve in it so it doesnt see pressure unless you open it up. Plus this is really something that need to always open at the same time because its going to make a big difference in your tuning. If you tune with it closed its going ot run your lean when you open it and if you tune with it open you'd be rich with it closed. Thats why I want one that comes on at a specific boost all the time, every time. I'll just run my boost right under that level daily and if I need ot race, I turn the boost up and wola, the cut out opens!!!

SnowmanSteiner

How is this different than a wastegate with a spring venting open?

- Steiner

SPOautos

Because your wg only opens at a specific time to control boost. A cut out you can have open whenever you want to....or you can have it closed when ever you want. You dont have that kind of flexability with a wg.

This product is basically designed so people can run a real restrictive catback (or still run the stock cats for instance) which would normally choak a high hp car but with the help of the cutout you can have the best of both worlds. Very restrictive and quiet when cruising, low boost, ect....very unrestrictive when racing.

This operates similar to a wg but you run them for different reasons

Large wastegates that dump to the atmosphere will benefit the motor by relieving some of the backpresure in the exhaust manifold . This dump will benefit the motor AND the turbo by eliminating the backpressure caused by a full length exhaust system , allowing the turbo to efficiently exhaust the gas thats passing through it. No matter how "HIGH FLOWING" an exhaust sustem is , it wil restrict to a point .Almost all the racers I've seen use large gates that gump to atmosphere TOGETHER with a cut off exhaust !! , If that wasn't necessary I am sure they would have run an exhaust system to keep the noise down.

I am thinking of putting using electronic solenoid in the sensing line (to the actuator) and having the E6K switch it on and off at the specified boost .

Marcel,

I've built devices similar to this, and flow checked them for effect. One thing to note is that these have a 90deg exit angle, which is not optimum. Gases flowing at a high velocity don't want to turn that quickly. Better results if the outlet was at least 30 deg or more from perpendicular. You can also put a 16 to 24" resonator with a min of 2.5" ID on the outlet with NO penalty in flow at all and it will quite the cutout down significantly.

Marcel Burkett

I will be only using the valve and the actuator , I 'll have my exhaust guy fab up a custom system with nice smoothe angles and joints.

Doesn't the wastegate vent the pre-turbine side of the impeller? This device appears to vent the post-turbine side, effectively removing the exhaust system after the impeller. Wastegates just let out the gases that drive the impeller, not the ones after it, right?

Carl Byck

I saw that the other day as well. Neet thing is you could control the signal to the cut out from the cockpit. This way, the thing is closed, unless you are in "Kill Mode", in which case, you now have straight pipes
