that will only work to the setting of the spring. if the spring in yours is 10psi, sure your MBC will work till 10psi.

when u apply pressure to the top of the diaphragm in your wastegate u can increase boost above the spring tension.

Re:external wastegate problems?
 

on my tial wg i have a mbc in the line coming from the manifold/ boost source, to the side port of the wg. the top port is vented into the atmospere.the tial has a 3.63 psi spring in it and i am boosting to 5.5-6 psi with no problems at all.everywhere i have read said the top port is for an electronic boost controller.

Re:external wastegate problems?
 

mine has a 4 psi spring and i am now running 10psi with the MBC..i`ve cranked it up to 15 psi a few times too.. ;D

Re:external wastegate problems?
 

The top niple if for an ellectronic boost controller. I use the side niple straight to the manifold or turbo. If you use a MBC you should run it in line with the side niple. Top of the wg should see atmospheric pressure. 98ctr

we told you not to buy that POS wastegate kevin.. when will you metrosexuals ever learn?

Re:external wastegate problems?
 

wastegate's fine bitch, i'm gonna kill you. come to find out, when i put the wastegate on, i was in such a hurry, i didn't put the metal seal ring in the bottom, so basically, for the past 5 months, i've had a half ass boosted car, put that ---- in and it sounds like stock now (use to sound like open headers), and the turbo spools up a million times faster, i'll have some video soon, my fukn manifold cracked as soon as i upped the boost to 9psi, oh fukn well. ---- is mad fast now and all i hear is turbo spool, then a loud as rfl bov, it's good to be me ;D

Re:external wastegate problems?
 

Well see the wastegate was compensating for your slipping clutch. just think the clutch would have burned up that much faster with the added boost.

Why again do you want to kill me?

Re:external wastegate problems?
 

^^I was waiting for someone to say that. If you plug the top nipple that should make the wastegate useless, wouldn't it? It wouldn't be able to move.

Is that manifold that cracked the SSatuocrap you were using? Where did it crack? Any pics?

^^^ see, that's what i thought too? but it works fine how i have it hooked up now, so i'll leave it as is. no cracks of the manifold, but it was cracked on ever runner and at the collector. i took it to my exhaust man and he rewelded the whole thing and put some more braces on it. the reason it cracke is b/c the stock braces fell off (they just had little tack welds holding them in place), up until then, it was fine for 5 mos., so i'm assuming it should be good for a while.

Re:external wastegate problems?
 

Thats how its done right there.

And if you forgot the seal ring your an idiot.., but we still love you :-*
