Stock Turbo Wastegate Question
 

Been tinkering with the wastegate cause I don't think I'm gettin the boost pressures I should be getting. I can only move the wastegate rod about a 1/4 inch. Is this normal or should it be moving more than that.

You can move it by hand that much??...It should move very much at all (at least by hand)...

By hand I can't budge it. I wedged a screwdriver in there and used that to move it back and forth.

This thing is goin back together in the morning to start pullin hay trailers in, so is the common concensus that my gate is opening and closing the full distance or should it be moving more than this. It always springs back in place so that it is pushed into the diaphram, I am hoping this is right. Sorry for the stupid questions but I don't know squat about turbo's. I have rebuilt and replaced most everything on this truck myself except inside the engine and the turbo. Now I'm workin on figuring it out.

Ok, I got ya now

Im afraid to say, that Im not a turbo expert either (or expert anything else for that matter).

Someone thats smarter than both of us will propably chime in here....

Anybody.

not sure but i locked mine shut with a turnbuckle.....

Is your truck and Automatic tranny. I know the HY35's can be turnbuckled shut but I can't find anything on this that I would hook it to. It's just a straight rod, on one end is a 1/2 inch long swivel that sits flush with the exhaust housing and the other end goes into the diaghram. So this doesn't leave anything I can see to hook to.

I would be hesitant to block a wastegate unless it is a race truck. I have no theory on that just a gut feeling.

Unmodified my WG, turbo, intercooler, intake, FASS 150 and 150HP injectors only get me 29 pounds of boost under really hard acceleration so adding a programmer like an EDGE would fool the boost limit some.

Which brings me full circle you probably have an issue with your COMP. Confirm you have it set right and try again before throwing money at this.

How can you modify the wastegate to allow the engine to create more boost pressure. Its for a buddies 2001?:U:

the wastegate rod dont move much..........I have rigged up a couple times with my air compressor and a gauge to set my wastegate where I wanted it and the rod dont move much at all

I disabled my stock wastegate with a turnbuckle and ended up trashing the turbo.................lotsa RPM will send it to orbit unless ya have a working wastegate....dont mess with it JMHO

Its a 2001 six speed has edge juice with attitude, CAI, 4 inch turbo back. Hes only hittin 25lbs of boost. whats the best way to get more boost?:tttt:

add more fuel will increae boost.................bigger injectors and if it were me I would do a better charger along with it


about 28 lbs is what he should be seein right now

Ok hes gettin a ATS 3000 soon but he just wants more till he gets the charger with out gettin sticks. Can the wastegate be disconnected to achieve more boost?:da2:

I would just leave it alone if it were me.............he is near the map effeciency anyway...in other words if he makes much more pressure it will be alot of hot air and that will just make the EGTs that much higher

he will love the 3000,...............push him forward towards that

He gonna need bigger sticks to lite the 3000 though
