Over boosting.....with racegate

[Mkid]

I have a turbonetics Racegate on the crossover with a manual boost valve.{the manual boost valve is almost all the way open{little or no boost setting}

Its hooked up like this.........

Side port{on racegate}to------side port on the manual boost valve

Top port {on racegate} to -----a T that goes to compressor housing&bottom port on the manual boost valve.

still creating to much boost?did i hook it up wrong??

:rock:

bottom port should get boost, the upper port hould be after the boost controller

I called up turboonetics and they said that the top port goes to engine vac at Pleum and the side port goes to the compressor.....

he said to put the boost valve in the line that goes to the turbo{compressor}.

I did that and now you can feel exhaust spitting out of the wastegate at idle no matter how the boost valve is set.

I'm throughly confused.

Thanks dude.

top port open to atmosphere ( leave the 90 degree barb on)
install the boost controller between a boost source and the bottom/side port. This is how Mark Hallman (Hallman boost controllers) specifies it for ext. wastegates. This is how I run my HKS external with rock solid control. I did this with both a 5# and 15# base spring

basically think of it as this.. apply manifold pressure to the side of the wg for base boost (top open). When you also apply positive manifold pressure to the top port, it pushes the valve closed. The more pressure you apply to the top port, the more boost you should make. The regulator is there to regulate the amount of pressure forced on the valve.

To eliminate the posibility of the boost controller being an issue,. just run a single line from the turbo to the side of the wg, leaving the top completely open to atmposphere. It should make whatever spring it has in it (probably 10psi) if it is still overboosting then your wg is screwed up.

Re: Over boosting.....with racegate

I have a turbonetics racegate with boostvalve and can't seem to got above base boost.

The bostvalve is in between the turbo compressor and the bottom/side port of the racegate, the top port is vented open. No matter what the setting on the bostvalve, I only get base boost. The wastegate and the boostvalve works (I have a bicycle pump and an extra boost guage) it just don't work when I am driving.

Can I run boostvalve with the racegate , it the a different way to hook it up or do I have to get a regulator type boost controller?

Thanks
Denny

Try changing the ports at the boostvalve.

If you have it backwards boost will never blow the ball open.

I have the boostvalve hook up correctly (bottom-boost in,side port- out to wastegate). I think the problem is the wastegate spring alone can't keep the wastegate shut, maybe I need to also apply boost on the top side.

I got a lot of time to waste :lol:
The way it is now

The way I am going to try.

Re: Over boosting.....with racegate

you dont want to install the boostvalve like they mention on the racegates. Install it like this:

To eliminate any issues with the gate itself run nothing to the side and straight manifold pressure to the top. It WILL overboost if the WG is in good working order.

Mike, thanks
I guess I should first make sure the gate is working ok.
