Hey guys need help setting up my boost controller. I can seem to get it to run anymore then 0.4 bar of boost. Have a gt3076 with 38mm external gate.

Any help would be much appreciated.

What settings should I be on?

Here are the instructions on how to install it to an internal gate and an external gate. Makes a world of difference when its wired up properly :)

I have the newer one to that it's the digital one and it's silver.

Yeh I have it plumbed right it's just the settings I just can't understand them.

SET is how much boost you want

GAIN simply put it, too much and boost will spike too little and it's lazy

Newer Profecs also have the Start boost, which works similar to the GAIN

if nothing is happening, you've plumbed it wrong

Oh ok well when I turn the controller off it goes unlimited boost. When on it runs .40 bar. I'm surprised that there is a .40 bar spring lol who wants to run. Like 6psi wtf

Sounds like you've plumbed it wrong already

When it's off it should only be gate pressure

Sounds like you have the NC and NO mixed up, try swapping the fitting into the other hole if it has one.

You have an external gate, why don't you just swap in a heavier spring? No need for an electronic controller really...

yes and no, the gate cracks open a touch before it reaches its defined gate pressure (if you want to call it that) running an EBC and utilising both top and bottom ports can keep the gate closed a little longer giving you a flatter boost response, instead of gentle ramp

I tend to like to let it spike a little and then the boost to settle, but that's just me :)

      I transferred from full time service to Army Reserve, so I still have access, work has been super keen to get me in to work in the OPS realm, so just turning up to use the gym......and ovens, isn't causing any issues, apart from me needing to keep on telling them that I won't be doing any reserve days until I get my joint in Goulburn sorted  Basically I can now work whenever I want, for how long I want now, and it's all tax free Next time we have some fires or floods you might see me covered in mud, or cutting sick in some plant equipment cleaning up, the Reserves love getting in the news, LOL

      Final finish outcome of 80°c was typical to the pics, I've turned the oven down to 50°c and will pick them up after the gym tomorrow  The before and after difference was amazing, the wrinkle paint has covered all of the casting marks completely It did take a couple of hours to key it all and get in all of the crevices, but, for me it was time well spent for the final outcome, but I have all the time in the world to do it at the moment  Ended up with 4 coats, each sprayed at different angles to get optimal coverage and thickness As for the fixtures and intake box thingo that hasn't made it, the supplier is apparently posting the fixtures, and, are now sending a different CAI that is in stock The replacement CAI is actually better than what I originally ordered, but will require a pod filter that locates under the front bar, still serviceable, but it basically removes the whole OEM filter box and ducts into the front bar, so filter cleaning will require ramps and the removal of some front bar undertray, not a war stopper, just some ramps and an additional 10 minutes work every few months From looking at it it is made from alloy pipe from the throttle body, through the CAI hole in the rad support, then right turning under the bar, luckily the wrinkle paint was on special and I got 2 cans for $30ish, so the alloy will get the same wrinkle treatment as the intake manifold, hopefully it turns up soon, either way, the car will be getting booked in soon, if the parts aren't here, I'll just get MX5 Mania to " make it work"

      I'm so glad base security is so high. I see they stopped some random codger from being able to just wander in off the street... 😛   PS, intake looks good!

      Is there a good place to learn how an engine works online?

      By RA708 · Posted

      Exactly how each part works and how they all work together to make the engine function. That's all I'd need to do a basic build. Maybe how forced induction works. I probably need to learn some of the maths behind it all as well.
