What the hell for? There's not boost to regulate or intercooler and piping.

You can always run a nice air filter like on a cold air intake and then have it go through the IC and into carb hat... That might work... probably more expensive than it is worth though

i am doing blowthrough so i will need intercooler...

That's fine, but installing the intercooler and piping while still running NA will be nothing more than a restriction. Once you have the turbo plumbed in, then the bov will be of use.

666cody666

well i know i will have to plum the turbo and stuff... my question is can a boost controller work on a carb setup

NO, carbs work on vacuum, not boost, are you sure you're up for this?

666cody666

well then how do you regulate the boost then? when directfreak ran a carb on his car he had a boost controller and it worked

There is a 'Failure to communicate' here. If you have the turbo, intercooler, piping and carb boost prepped and installed, then yes, you need a bov. Until you have all of that installed, then the only thing in that parts list you might need is a boost prepped carb for pre-tuning.

Will the Profec B when you are turboed, yes.

dude, correct me if im wrong, but i think he's talking about "can i use this boost controller ONCE im turboed?" I don't think he means right now. And just so you know the profec-B is an electonic boost controller not a blow off valve. Greddy's blow-off valves are the type-s, type-rs and i forget what the others are if there are any. not trying to be a dick so please dont read it like i am cause it might sound like that

Also you dont NEED a bov on a turbo motor, its just a good idea, plenty of factory turbo cars dont have bov's, wastegates are another story, though.

I stand corrected on the bov/ebc misunderstanding. All I can say is the Devil made me post. LOL.

Thank you^^

If I remember right the profec-B piggy backs off an ECU, so if your going carb'd that is a no go.

Incorrect. Profec B is a stand alond boost controller with three different settings. It's a great unit, but stay away from the type-B

Setting 1: Boost Controller Off, Turbo boost pressure decided by wastegate spring alone
Setting 2: Boost Controller On, - at whatever you set. (always above wastegate spring pressure, never below)
Setting 3: Boost Controller On, - at whatever you set. (always above wastegate spring pressure, never below) - likely higher than setting 2.

On top of the that, the Profec b has a "gain" dial, that lets you control how slowly, of quickly you want the wastegate function to open. If you dial it right, it will make a WORLD of difference with traction, so boost won't come on too abruptly.
