Item is assembled and bleeder hole drilled, i have 8 of them currently.

They hold steady and are easy to change.

looks really nice. do you plan to mass produce them or are they special order? i think i want one. well see in the next couple weeks what happens.

Re: Manual boost controllers
 

I have these all here now...no mass reproduction but I will make more if needed. This style has been around a long while and I just have them made up for local tuning customers that need a good (actually working) manual boost controller so we can get through the tuning appointment.

These work well and are solid...they help spool up as because they dont open until the wastegate needs to, which keeps it closed for longer and doesnt leak boost prematurely. The bleeder holes are carefully machined in with a 0.020" hole to prevent boost spiking from this type of controller.

great man. i will pick one up later if i can get some sort of paycheck(24 hours a week is killing me i tell ya).

This would be perfect for my colt. Can you put up a pic of what the top of those look like? The side view makes it look like the fitting is coming right out of the top of that adjustment knob. Is that really how it is? So everytime I adjust my boost, the fitting is now pointing in a different direction?

Re: Manual boost controllers
 

You got it! That is exactly how it works...but once you get it set, how often do you need to change it?

Honestly at the track I have second one set for higher boost...the other set for low boost (street), just swap out the controllers.

Re: Manual boost controllers
 

Thanks for the responce, but I thnk I'm going to pass then. I adjust it enough that I'd probably get a little annoyed by it. But for someone who never touches it once it is set, looks like a good deal! Good luck with the sale.

Re: Manual boost controllers
 

its really not all that hard honestly...pull off hose, loosen adjusting nut...turn in/out to raise/lower boost...tighten adjusting nut...reconnect hose

Ill take one man.

in the mail ;)

Re: Manual boost controllers
 

is it possible to use one of these and 'disable' the internal wastegate so i would be able to run my tial wastegate?

Re: Manual boost controllers
 

You would probably need to use a blockoff plate for your downpipe which blocks the internal wg hole.

Re: Manual boost controllers
 

a block off plate is next to impossible to find since im using a turbo off a skyline. i was thinking of just turning up the boost on the internal wastegate to something like 20PSI while i use my tial as the actual wastegate set at anything under 20PSI

Re: Manual boost controllers
 

Just don't hook up a vacuum line to the internal gate, and run the MBC off the external gate.

Re: Manual boost controllers
 

wouldnt he still get blow-by from the internal wastegate, even though it isnt connected via boost controller due to exhaust pressure buildup?? wouldnt it have to be welded shut to prevent boost leak/surge??

Re: Manual boost controllers
 

Well one end is straight so no matter where the other end is after adjusting, it's still going to fit the same way. :1

it would probably be a good idea to tack weld it shut yes
