Did you have to adjust your NEW PTE internal gate turbo?

[bfdahl]

I installed my new PTE GT 30 the other day and realized she didnt want to go over 19 psi.

I disconected my wastegate acuator from the Profec B and went for a ride.

my thoughts were if i had easy quick boost over 20 psi, that my controller may be dicked.

but 19 psi was it and that was that. so Im thinking I need to adjust the acuator on the turbo. I remembered that the lock down nut was loose when i opened the box. and I just
ran it down before the instal.

It looks like a PITA to adjust on the car........Tips any one!?

Should be fairly easy to adjust on the car but may be tight depending on your setup. Adjusting an actuator should be fairly straight forward. Losen the lock nut, remove the clip holding the actuator arm to the flapper, check to see how much force is holding the flapper shut. When you remove the actuator arm you should have to extend the arm to get it back on the flapper, this preloads the flapper. If you want to increase your boost you will have to add more preload so you want to shorten the arm length abit. Install the actuator arm back on the flapper, install retaining clip then tighten the lock nut back up & you should be good to go.

After re reading your post it sounds like you have a boost controller issue as you are seeing the same amount of boost with & without the controller. Just to verify when you removed the controller you just hooked the WG actuator directly up to a pressure source or did you not hook anything to the actuator line? (in this case it wouldn't be the boost controller) Did you leave the actuator connected to the flapper or was the flapper just "flapping"?

If you left no line on the wastegate, then the boost should rise uncontrolably. I'll make a little chart..

1. If you hooked nothing up to the wastegate nipple, boost should keep rising. If it only hit 19psi and stopped, then you have problems such as a really bad boost leak.

2. If you hooked the wastegate nipple up to a pressure source (bov line, port on intake manifold, nipple coming out of compressor housing) and it went to 19psi then stopped, you have a boost controller issue.

Yes, i had no hose of any kind on the wastegate nipple on my road test.

I just cranked the adjuster back 4 turns and im out to run it again.
(an hour later)
well, that didnt do much. Wondering if i need to pull out my cat and run a test pipe?

Ohokay, so with no line connected to the actuator, yes you should basically make infinate boost. When you say cranked the adjuster back 4 turns, you mean you shortened the rod, correct? (as this is the direction you want to go). How much pressure is on the flapper when you install the actuator arm? Have you done a proper boost leak test & checked for exhaust leaks? A cat shouldn't restrict the flow like that, that is unless of course its damaged (sometimes physically melt).

 

[bfdahl]

Yes, I turned the rod to make it shorter. I ran a socket over all my clamps and checked
the exhaust manni nuts. I want to drop the cat and look inside, you see a couple of years ago i blew out the back half of it running some 100 oct. though it with out leaning it out properly and i cant help but think that maybe the rest broke off and is jammed in the the tail pipe.

Its always good to have your Internal Gate cranked down as tight as you can get away with.

^ Why the heck was he suspended

Anyway, There are 2 ways to go with adjusting your WGA.

Tighten - more load, faster spool, larger boost spike
Loosen - less load, slower spool, smaller boost spike

or just leave it alone and fix the plugged CAT that is causing a HUGH exhaust restriction!

(see my other post on found my lack of power problem)

I should have mentioned, I wouldn't adjust the WGA and leave it the way it came from the vendor.
