I would pull the wastegate apart and take a look, your plunger could be stuck half open or something.

 

from the look of it, it opens with just an allen wrench rigth?
ive never taken one apart
how would i know if its stuck or not? push it and see where it stops?
it has to still be opening and closing, it just seems to be opening early

 

Well the easiest way ive found is grab a C-clamp, tighten it down on the "dome" first, then undo the allen bolts. If you dont clamp it the spring will give you hell when you are tryin to unbolt it.

Once they are all out, loosin the clamp and it will come apart, make sure the spring is in one piece (ive seen them snap) and that everything looks in good condition.

 

thanks for the replies rozz-tC

but i have another update!
haha
so i just did the soapy water test, and exhaust IS in fact coming out of the wastegate to manifold flange.
ive tightened it down as hard as i can and its still coming out.
could it be warped? or does the gasket have to be a certain way?

 

could be warped, but to be honest a small leak there isnt going to limit your boost like that, my gasket fell out, completely. i still built boost, took alot longer to spool but would still get there.

Still something you wanna get fixed im sure, but not the cause of your main issue. once you get your issue fixed you can take it to a machine shop and they will make it true pretty cheap. Take both the manifold and WG, they will make it so you dont even need a gasket lol.

 

did you ever put the cardboard between the wg and flange?

 

tried, but the screws arent long enough
and when i took the wastegate off, i noticed the gasket was burned and i assumed that was the problem.

 

if it actually burned that means that the gap was pretty wide

 

well it was black on the top half. may have not actually been burned.
i tried putting the wastegate on without a gasket like you suggested and it still leaked.
i still havent tried a brand new one yet.
the gasket i used was the one from my dump tube

if its warped, how would i be sure of it? put a straight edge or something?

 

you can run rvt between the wastegate and mani, and wastegate and downpipe, that should fix that leak

 

I dont know if regular rtv would withstand 900+ degrees celcius. That stuff is usually only good to about 600F max.

 

i think the copper rtv can withstand the highest temps of all the rtv's but still i dont think it is rated for 900+f, could be wrong though. I noticed i have slight leaks here and ther that i need to attend to so id like to find something i could coat my gaskets with that would hold up.

 

It will, tubonetics recomends put rvt between the hot side of the turbo and the downpipe, check out there turbo install direction on there website, and I run it on my wastegate with no problems

 

I'm gonna have to look into that, lol.
