not really i used one of those you hoot it up to the top part of the wastegate and put counter pressure on the diafram helping the wg spring out..
btw the paint job is BE realLY GANSTER ***!!!!!

 

i got 2 of them grainger valves today fro 21.10 cant wait to get my boost control on

some one should make a spimple electronic surcit taht would hoook up to the vss (vihicel speed sender) and would count the electrical pulses so you can have a step boost control by gear from knowing your speed it would know waht gear your in just like a high buck apexi unit or greddy
this would be the ultimade boost control plust it will carry the HMT logo for doing ---- ceaper better and it being faster then your shiney name brand ----!

 

I toyed with that idea, even tried to modify an RPM switch to do the trick, but I didn't go to in depth with it. As my electronics skills don't go any deeper than designing simple logic circuits like the one in the diagram. In reality this piece actually worked out fairly well, but I took it off while I was trying to tune in my new setup and never put it back on... Laziness owns me

If you want a cheaper speed based boost controller try using the Crome Pro + gold rom. I think is has 2 or 3 user programmable outputs. I haven't messed with it yet to find out though. I've been rather dormant from wrenching/tweaking lately.

Thanks to all the posters than found this thread useful.

 

For all the noobs... go buy one and GTFO this thread.

 

^^^^^ word

 

badass car im impress of how clean it is

 

i tried this setup but the solenoids were 2 restrictive for me. 6lb spring, and it kept hitting my boost cut at ten psi. Everything was hooked up right and functioned but was 2 restrictive.

 

ive looked at this thread many times and have just now realized how this boost controller multiple settings works.
pretty good idea.

it would almost be just as easy to find a toy or electric appliance that has a spinning motor in it and
hook that up to your adjustable ball and spring. then just make some type of control to turn the threads up or down
on a single homemade boost ctrlr.

then at a stop sign you could just up your boost.

 

has anyone actually been successful with this. im not gonna do it. im just wondering

 

nice
