HD waste gate

[blackmonte]

I put a heavy duty waste gate on the new turbo and I cant adjust the arm long enough to get the 23#s i am looking for its going past 25 #s and I really don't want to run that much boost on the street., If I adjust it too long the puck will be slightly open, I thought when you adjust the arm the puck should have some pressure on it to stay closed until the desired boost?Do they make a longer or shorter arm?Thanks oh and who has them in stock?

Is it possible the puck is stuck?

When you adjust the arm all the way out.... until you have to pull it about 1/8" to get it on the puck.... this is the minimum boost setting. It shouldn't be more than 17-19 lbs.

Next... check the vacuum lines.... is it possible there is a boost leak before getting to the wastegate actuator? Are you still running the wastegate solenoid? You can bypass it to test... and run a vacuum line straight from the turbo outlet to the wastegate actuator.... this should drop your boost a couple lbs if you were running it through the wastegate solenoid....

The puck moves freely thought the HD waste gate was 20#s start to 30#s? When I close the puck I have to shorten the rod to make the connection to the puck so it has a small amount of tension on the arm for the puck. at that point I am getting like 25#s . I am still using the stock wastegate actuator. I will check vacuum lines thanks.

In your first post... you said you were using a HD actuator.... in the last post... you said it was a stock actuator....

The stock actuator minimum setting should be 13-14 #... the HD should be 17-19#..... minimum. A "bleeder" in line with the wastegate actuator will alter the boost the actuator sees.... and raise the boost level..... the stock solenoid does that to an extent... again raising boost a little. Early chips used to "pulse" the actuator more than stock making a little more boost bleed off getting to the actuator... thereby raising boost a couple lbs... w/o adjusting anything.

If you are running anything not stock in the vacuum lines going to the actuator.... it will effect the boost.

IMHO....you should not be getting boost that high.....

My bad I thought you were talking about the wastegate solenoid ,not actuator it is a HD actuator ,Kinda weird because with the stock turbo I was running 20#s all day with no spikes now with the new turbo and DP it climbs fast to 25#s? I thought there was some arms in different lengths you could use to get the psi you wanted ? Oh well thanks. Gotta wait until it gets warmer anyway.

The HD actuator is not really meant to be run with the wastegate solenoid still hooked up or you will see some spikes. The HD actuator is made to be either hooked up tuner style, or with an RJC bleeder valve. Also, depending on what turbine wheel your turbo has, you might have to port the wastegate hole just smaller than the OD of the downpipes puck. Running the wastegate solenoid can cause some spiking issues and for the boost not to go higher than 25psi. But, running it tuner style or with an RJC bleeder valve and you will be able to turn it up to 30psi. Not porting the wastegate hole on a P-trim turbine wheel (or larger) equipped turbo will result in very little boost control.

Not sure what tuner style is? But I did just order a adjustable wastegate valve from SE turbo has the knob on it to adjust boost easy, going to try that see what happens. Any pictures on the grainier valve set-up bypassing the boost solenoid? thanks

Thanks guys found the problem the puck was getting bound up (rick87gn):biggrin:

So what did the minimum boost settle in at.....

 

[blackmonte]

23#s using compressed air couldn't drive it(friggin snow) but at 23#s it opens , I hope it works.

What turbo did you upgrade to?
I ended up having to port the wastegate hole in order to get the boost down.

Hmmmm, wouldn't think the WG hole would cause that much of a boost issue with that turbo.
You might be on to something with a sticky puck.
