Long as you can adjust the boost to wherever you set it, it's not important...Di d the car pull better?

The boost controller is bottomed out so no more adjustment there.  I may shorten the actuator rod a full turn and see what happens.
 
Seat of the pants.... it felt better. No KR but would like to get the boost back up before pulling more fuel

I assume this is an HD actuator.  In that case, it does not sound right.

Open the controller and shim the spring a bit with a washer.  You should be able to obtain 28 psi, or so.  If that does not work, try wiring the wastegate arm closed and carefully see if the boost goes up as it should...be prepared to let off before it goes too high


We just went thru this with Shimy and finally found out his intake gasket had a big time leak, but that is a rare event and he had a lot of blowby which gave me the hint

To get mine to work I had to set the arm about 1/4 inch pull to get on the pin and my boost controller is dam near maxed out. About a turn and a half is all I have left to run 25 lbs.

That was my original thought, adjusting the arm.  Then maybe I can back off on the boost controller as its a bit easier to adjust when things get warm down at the actuator

Guiness Book Of World Records has me named as the only person on the planet that adjusts his boost pressure with the actuator rod.

I like my external :p just turn the controller. I mounted it under the hood so I wouldn't be tempted to play with it.

X2 on the rod controlled boost. Much more steady. Harder to goof it up that way.

Dug around last night as I thought I had a newer HD actuator only not with the E trim bracket.  Found it.  Cut the bracket off the older HD actuator and welded it on the newer one.  Adjusted the arm to about 3/16 pull and renistalled.  Backed off on the boost controller 2 full turns.  Let you guys know this evening how she does as it was too late last night to go for a run.

I like doing it on the fly from the driver's seat through my MAF T Pro.

Well boys... We got boost!  Started at around 65 in overdrive, car down shifted and before I could look at the boost gauge/fuel pressure gauge and scan master, she locked the TC. That meant I was already over 100 because i believe that's where Eric sets it to lock up.  Definitely pulling better! 


Won't be able to make it to little River again this week.  Last home football game of the season.  Daughter is a freshman in the band and my son is in 7th grade band who is getting to play with the high school band at the game.  At least I'm here to attend.  Spent too many years across the big pond when they were younger

[Steve Wood]

good!

[Scoobum]

It's pulling in 3rd gear with a fresh set of valve springs? Nah...couldn't be.

Made a trip up to Hillsboro last weekend to meet up with TexasT and Charlief1.  On the drive up, I noticed what I would call harmonic vibration.  The vibration is subtle but noticeable on the fuel pressure guage that I have mounted on the hood.  The vibration comes and goes depending on the road conditions and is more noticeable on the smoother roads and is consistant.  Doesn't happen till above 50.  I've noticed it before but didn't think much of it but since this is my education thread, I thought I would throw it out.  Drive shaft balance?

[Charlief1]

 Most likely U joints.

Made it to little River this evening. Made four passes. As usual, bet pass was the first. Couldn't get the tires to stick after that first run.  New personal bests for me for the 1/8th mile. If I did the math right, could be an 11.91 in the 1/4.

[Scoobum]

Hey...congrats! Equates to an 11.91 at 108. PL log for the run?
