How many PSI can you get out of the stock type WG

[blackbuick87]

Whats the most you guys have gotten out of a stock type actuator? I tightened mine down as far as I could and the most I can get is 20PSI. At least I did not get any boost creep. Thanks

That was the limit for me too. I went to HD actuator and now have about 3/8" more range which should be plenty for going higher soon.

I shortened the rod about 1/4" and maintained 26-28psi with no problems....

I'm thinking about wacking 1/4" off also. Kevin once you did that could you still turn it down to say 16psi if necessary?

 

[KEVINS]

I think 17-18 was MINIMUM! It was barely hanging on by a couple of threads though. Do a little at a time or do some measuring/calculations b4 cutting....

Thanks Kevin, I think I will stay at 20 for now then. I still want to be able to go back if I need to.

19psi for me.

I hit over 30 lbs with the stock actuator, but that was because I blew off a vac hose.

I was able to hit 22 psi without a problem with the stock setup.

Why don't you guys try a bleeder valve. I use one in addition to the stock solenoid and WG actuator. You don't have to put so much pre-load on the WG actuator spring. You just open up the bleeder a little more to raise the boost.

With the bleeder closed I'm at 14-15 lbs for pump gas. Load up on race gas, open the bleeder and the boost goes up from there.

My wastegate arm was stuck shut when I first bought my car.
I got a boost gauge on and I saw it boost past 25lbs..
Oops!
At least I know it can go that high.. hehe

I think they look tacky... I now use a grainger valve and it looks tacky also... It has nothing to do with operation, only looks. Everytime I open the hood I see it and try to think of some nice way to "decorate" it... lol... I may go back to the stock setup once I get things figured out...

Boost Commander!

Much better than a dial a boost, somewhat cheap and very linear.

I was hitting 20 psi in an overboost condition. Don't that on this crappy California 91 octane is not good. I can't wait for my SMC kit to arrive

20 psi on pumpgas club

Doughboy, glad to see I'm not the only one that accomplished 20 psi on pump gas. After cleaning my intercooler, and after some WG complications, I boosted it up to 20 just for a fraction of a second. I expected to see headgasket blown all over the engine, but she held up (I THINK). Definitely scary, but I wouldn't sweat it.

Duct Tape works wonders

speaking about stock WG actuators, I have an original non-adjustable with a Thrasher 92 chip.

Would a non-adjustable WG be holding boost back? I have heard the Thrasher will try to get 20psi in first gear, which I can never get. What really controls boost? chip or actuator?

Thanks

Batman, both. Sometimes unfortuantely.

A chip that gives you say 18 psi. in 1st and second gear with a stock actuator will now give you more or less if you should make the actuator adjustable and start playing with it.
