Idea I have been toying with for my 1st gen

[Callan]

So here is the deal, I hate turbo bark. I can bark my turbo really easily and considering its an automatic it would be even more annoying if i decide to make it a stick. So i have been thinking of the idea of making a blowoff valve that would release the excess pressure on the intake side of the turbo to prevent that pressure from forcing the turbo in the opposite direction.

I have a design that i have been working on but basically the idea is to mount a sensor on the throttle linkage that is linked to a micro-controller and will monitor the rate at which you let off the throttle that will activate the blowoff valve.

Now there are other factors I have taken into consideration including, time the valve is open, closing of valve immediately when your back on the throttle again, and many others i'm sure i'll run into.

But basically i am looking for being able to not worry about barking the turbo, or being able to fly through gears without worrying about barking if I go standard.

Anyway what do you guys think?

Any opinions/ideas? Input is greatly appreciated.

I'm not much with electronics but I think if you can make it work it would be a very nice thing to have. I know somebody makes one now that is electric and really spendy, I don't know how if works though.

I have no problems with programming the micro-controller or designing the circuitry. But definitely looking for some input or ideas on how i could improve what I am starting with here

Check out BD's instructions for theirs, it should give you a good idea on what you need to do.

A guy on another site bought a 38mm one with a boost line to it. He just ran a line to a port for drive pressure, and the drive pressure keeps it closed. (it has a light spring in it too) When you let off, drive pressure drops, and the BOV opens and dumps boost. Slick setup, looks good too.

And it's not $600 like that one either!

yah, i think i like ptoombs idea, i have seen that before and it seems to work well, you could even set it up electronicly if you wanted to do it that way, it seems simpler than working with the throttle linkage...

let us know how you do it

[Callan]

Yeah I really like that idea, I really wasn't set on doing it electronically. It was just my initial thoughts and how to do it. Although i drive boost line to keep the BOV closed is good. Do you have any more info on it?

[PToombs]

I'll see if I can get more info.

[Callan]

thanks bud, appreciate it!

[PToombs]

Here is the link to TDR. I think you can get the 1st page, which has most of the info. The links no longer work, but I'm sure you can find the BOV's easy enough.

Good deal here!

haha nice! i will keep an eye on that one. Thanks for the information, I will keep working on it and maybe have it up and running by spring!

Thanks again

[PToombs]

No problem! If you need anything else, let me know. I can always PM the guy that put it on his truck.
I saw the other 38mm ones going for $200 or better, so I figured I'd post that for ya.

[Callan]

Would you be able to PM the guy that did it and ask him what spring he was using in the BOV?
