So what's the advantage of this method over having one solenoid on the top and one solenoid on the bottom? Like if I wanted to remove pressure from the bottom and allow the valve to shut quickly by venting the bottom. I looked through your other videos and I don't see that you have a video on the other dual 3 port method. Very well explained video though
You wouldn't ever want to dump the bottom of the gate. That's the balancing pressure coming from the manifold to tell the gate to open when the spring force is met by manifold boost. Two things open the gate, backpressure and reference pressure (bottom). 2 things close the gate, Spring force and applied pressure to the dome from the mac valve(s). So in this case whats nice is how fast 2 3 ports work and the ability to manipulate a pressure curve very quickly and hold a target rather than just applying a little more or less to achieve a target boost. This method would allow you to do something like say 20psi on the starting line to build boost, then quickly dump some to manage launch power then ramp back in to a plateau and even change the plateau for gear changes etc. a single 3 port can try, but its not every going to be as good or fast and will be very wasteful with co2 or onboard air to achieve the same goal
@@greenshortsperformance472 The bottom solenoid would be set up to only dump between shifts. the pressure is removed from the bottom of the spring only then. I may switch to this method though, I just finished running lines and configuring my ecu, but i ciuld easy switch. I'm not running co2, just turbo pressure. Would I need to run a dome pressure sensor for this method? In my haltech i can set up dual solenoids but this is only used for co2 (i asked haltech a while back and that was what they said). So I set up a generic output to control the second solenoid. It makes sense to me that I can run it from boost pressure instead of co2 though.
Awesome video series brother! I have a request, I'm interested in an E-gate. I have been trying to find more info on using one but the info is still pretty limited. Fueltech has a controller that would work and Turbosmart has a straight gate setup. Cheers man, and thanks for sharing!!
On this setup you can only double your boost from the size of your waste gate spring so if have 10 ib spring to will 20 ib of boost and you can launch at 10 ib no lower is that how it works and what number are the tee and for the fill and vent ?
A four port will typically give more range. Four ports are good for cars using compressor source that need to leave on very low boost and still make a lot down track.
Just trying to understand, so this presentation expect us to be using manifold air pressure and not compressed CO2. Looking to implement similar dual 3-port setup with manifold air pressure, rather than with CO2. Great vid. 👍🏾
Compressed air and co2 are effectively the same one just must be refilled often but is overall lighter When using manifold pressure be sure to select compressor as the pressure source not fixed
Great videos. Should be mandatory watching for all people moving to an external waste gate setup. Thanks for posting 👍

Nice video, subscribed.

I didn’t see a video of open closed loop explanation as well as PID.

How about how to set up nitrous and how to set up a base tune!
does this way give you more range than a four port
for example i can run 40psi with 15 pound spring
