Who has ran one of these with a 1bar actuator?

I had mine on the dyno with it and when it had absolutely no preload on the ball so I could freely blow through the bottom the lowest boost level I was able to achieve was ~19psi. Boost was then tailing off to 17.5psi; I assume due to not enough preload causing it to operate like a traditional bleeder.

On the std rb20 and rb25 actuators it was rock solid; held boost perfectly.

On a mates external gate setup with an 8psi spring it too was rock solid; just didn't like my stiff wastegate. :S

Im assuming the hole drilled was a tad too big and bleeding too much off.

The boost controller on ebay is here.

I bought one couple weeks ago. Easy to attach and use, great results on a close to stock setup. I upped from factory boost (5-7 psi) now running up to 11-12psi. Very happy! :unsure:

interesting 1 for ya. i had my car on a mates dyno a while back. Got 179rwkw @11psi using one of these boost controllers. changed it over to a new turbosmart one just to see if any difference was made to output and got 186rwkw at 11psi.....

interesting huh.... can anyone shed some light on why this might have been??

The bloke selling them on ebay is ok to deal with, its cheap, easy (too easy) to install cause you dont need to buy anything else and it works. Installed mine about 3 days ago all seems to be ok so far, im happy with it.

Has anyone else had an issue of boost dropping off higher in the rev range?

Mine has been working fine for ages & i just came back from holidays and noticed it was dopping off about 1.5psi.

I've given the spring a slight stretch but it didn't seem to do anything.

My boost is set at 12psi and it hits it, but it drops down to 10.5psi.

I've done the exact same thing, back to back, with my car, without touching a thing. It's just how the dyno calcs to give minor changes.

I'm running one of these with a hks actuator and with almost no preload on the ball it makes around 15psi...with preload and adjusting it i get about 18psi with a 2-3 psi spike in 4th gear...i guess its because i'm using a longer hose with the valve and also because it is a mechanical system and it takes time to stabilize...

i use one, it works not much better than a turbosmart ball and spring in my opionion, yet much better than all bleed type (needle valves) ive seen, it works instead of bleeding off excess boost it restricts boost from getting to the actuator by blocking it off till it has enough pressure at the ball to push back the spring

      No not yet.  Hopefully this weekend if I can pluck up the confidence!  I had to sit in the car at one point yesterday to unbolt the rear struts.  As mentioned in an earlier post when I was putting it together there is still a bit of rotation possible so when I sat in the car, it rotated a little bit.  I near shit myself thinking the whole thing was coming down!  I do 99% of my own shit in the shed but I think I might call on some assistance the first time I spin it!

      Strong first post. On a Skyline-centric forum. Have you considered actually going out into the world, visiting the actual dealership, and asking the parts guy over the counter? Or at least just call them up on the phone?

      2004 Subaru Forester X Under Cover craziness!

      By Apache23 · Posted

      Trying to find the plastic under cover for an 04' Forester X. The main under cover that covers most of the front of the vehicle under the engine. This has turned out to be a crazy experience. Normally I can find parts for vehicles, if I have the correct info, no problem. But not this! The Forester is a non-turbo btw. In a Forester parts catalog, for model years 03'-06', it shows part# 56410SA070 as being the correct part. So I go to the local Subaru dealership's website to order it. I type in the part#, hit search and there it is, the under cover. "DOES THIS PART FIT YOUR VEHICLE?" I type in my VIN# and sure enough, "This Part Does Not Fit Your Vehicle. See Similar Parts For Your Vehicle." I click on that and part# 56410SA000 comes up. Looks absolutely nothing like the previous part. Not even close. So I go to a different Subaru dealer website and put in that 2nd part# (56410SA000) and "This Part Has Been Replaced By" 56410SA070, which is the first part I looked up. I thought OK, makes sense. They replaced the strange looking part, with the one I looked up first, so I add it to the cart. "Does This Part Fit Your Vehicle?" I type in my VIN#, and sure enough, "This Part Does Not Fit Your Vehicle." I've basically been doing this with various parts suppliers and dealerships, for the past 4 hours! Does anyone know what the hell is going on?? Thanks in advance!
