I was wondering if the RJC bleeder valve would work on my car with spool up.My boost is controlled by a Racegate underneath the car in between the crosspipe.Would I have to get a Terry Houston Downpipe with the stock type actuator in order for the RJC valve to really work for melpaulabbott said:if you havent already install a rjc bleeder valve spool up is almost instantanious

not sure but i am sure rjc will let u knowxrunner123 said:Sorry to bust in here but I was wondering the same. Racegate mounted in crossover with knob adjust for boost. Can the RJC valve work in this config?
So I guess having a Wastegate or Racegate like I have near the crossover pipe might be a little more complicated.Maybe if I had the original style wastegate right on the Turbo like stock it would work better I would have to get a Terry Houston Downpipe for that though.For some reason my boost controller from inside the car doesn't work any more since switching Turbo's so I have to switch something around so I can adjust Boost.bison said:It will work, but usually the spring in the wastegate isnt stiff enough to keep the gate closed. The exhaust pressure pushes it right open(The boost controller has no effect on this). It will work well if you can keep the exhaust from prematurely opening the gate.

I visited the site and saw the RJC bleeder valve near the Turbo.I also saw what looks like a gauge there right next to it.I have had my setup with the Racegate for so long I can't figure it out but I doubt the RJC bleeder valve would help in my configuration??I definately got a bad setup for quick spooling. Is there that adjustable rod for the boost like with the Terry Houston Pipe or is that picture with that Turbo and the RJC valve a different configuration toolpaulabbott said:if you havent already install a rjc bleeder valve spool up is almost instantanious
yes i set the wastegate rod to 1/8 to 1/4 inch preload to where it hook on the puck arm then i adjust my boost with the bleeder 1 turn for every poundSly87 said:I visited the site and saw the RJC bleeder valve near the Turbo.I also saw what looks like a gauge there right next to it.I have had my setup with the Racegate for so long I can't figure it out but I doubt the RJC bleeder valve would help in my configuration??I definately got a bad setup for quick spooling.

I was running a racegate in the crossover on my last engine and i sent pressure to the top of the diapragm and it still would open from exhaust pressure. I just disconnected the side that pushes the gate open and kept the top side pressurized and it still opened around 14 psi manifold pressure. I was dumping the wasted energy to atmospheric and could easily hear it. The larger area on the back of the valve increases the MA of the exhaust pressure allowing it to open under pressure. You will need a much stiffer spring than the 9 lb. I specualte this is why the guys running big gates use CO2 to hold the gate closed until they need it open. Usually via an electronic boost controller. The stock setup would do the same if the wastegate hole was large enough, the valve was big enough, and the diaphragm had a weak enough spring in it, even if you didnt notice. Smaller surface area equals less MA.turbo2nr said:Most external wastegates have a diaphram on both sides, so you would not be using only the spring, but also pressure on the back side of the gate. At least that's how I got mine set-up.
Otherwise, you would never be able to get boost over the spring pressure. What would help to keep it closed?
My spring is only a 9 pound.
