Apex MCX 16T waste gate actuator?

[TURBLUE]

Is this specific to MCX or can you get from a supplier of the Mits 16T Turbos? Mine had a bunch of water in it and froze( I from assume snow dust) Also the dude that installed the kit had straightened the control arm cause it was pulling to much boost and now it rubs on the housing....the boost is all over the map it seems so hopefully this is the problem... What is the max boost can I get out of that waste gate actuator without a boost controller?

I know you can get them from MCX for 250 wondering if there cheaper anywhere...seems high for a small valve actuator..

Has anyone run a actuator with a higher presure spring in it? instead of using a boost tee.... I believe the one on the mcx is only good to 12psi

Check with Ted, he can set you up, i read several posts where he gave advice to change spring in the actuator!
I highly doubt that you have only a 12psi spring tho, but everything can happen .

by 12psi i meant how short can you make the rod to get it to 17psi.....will that work with the actuator thats on there?

thanx

anyone?

I have tried to raise boost by shortening the WG arm, the highest I got (before getting uncomfortable with it) was 13 lbs/psi.

What T-Bird says can be done, I do not know about the Mitsu actuator tho, but you could always adapt a Garrett actuator to the turbo.

Is the actuator still working properly?
Bend the actuator arm so it wouldn't rub.
What sled and turbo system??? Apex with MCX260???

If your sled is a RX-1 carbed sled I would choose to buy a Manual Boost Controller like Hallman Pro RX.

rxrider,

Why for just a carb'ed sled? I bought one for my apex but haven't installed it yet, is there a catch you knwo of to using it with an EFI?
Thanks

its a apex 260kit 2006 upgraded to 310 kit with lc pistions......I was playing with it last night i think i got it bent so it doesn't rub......so 13psi is about all I can get out of that actuator? So to run 17psi I have to run a manual boost controller....

thanks for the reply

Or install a bleed valve, simple way to rise the boost.

Works on an Apex as well.

About 13 lbs in my experience adjusting the WG. A MBC would work great for raising boost. I would leave the WG arm alone if boost is at 12lbs and adjust via a MBC. I bought a few Hallman Pro RX on e-bay, paid about $80-100USD a piece.

Bleed off valves are not my favorite way of raising boost, too many problems in my opnion. Running the Hallman, no problems so far.

How tight can you go with the waste gate acuator rod? 1/4 to 1/2" of preload sound right? what if you go to much?


are there knock Hallman Pro RX controllers on ebay? how can you tell the difference?

What problems are you refering to?
Have been around a couple usng them, no problem to my knowledge.

My bleed valve froze shut once. Boost levels were very inconsistence with the bleed valve. I know Skydog had the same problems. With the Hallman I've had no problems with freezing, and very consistent boost levels. This is what I have experienced running it, my friends had no problems using them tho

They can be used, no doubt, but as I said they are not my favorite.

 

[TBird]

I was only curious, freezing is a big problem on sleds, in many areas, so i can believe it happens in boost controllers as well.

Bleeding valve is very cheap and easy solution if you want to run higher boost and also want to be able switching between two boost levels, many settle with that, others want to be able to adjust boost levels not only between fixed boost levels, but to the amount of boost you want at that moment, if you want that a Hallman is a very cheap solution, just not as cheap as an bleed valve, that works very well, the choise is your's.

well I have a turbosmart bleed valve on mine right know and it seems to jump around lots
