How to adjust SBR ( Forged performance ) T28 actuator

[hottboost]

Just as the title says. Mods are current. Just fixed all boost leaks and boost is still falling a few psi. Got the adjustable actuator today and am installing it tomorrow. My question is when I put it on in which direction do I turn it to run higher boost. I am still using mbc but I want to adjust the actuator to where it doest allow the flapper to blow open. Do I adjust the arm to be longer or shorter? Silly question but I want to ask to make sure. They said that it would have the 14 - 18psi spring. Does anyone else have expierence with this product? Thanks in advance!

making the arm shorter puts more tension on the diaphram requiring more pressure to open it, meaning shortening the rod arm will give you either stable boost or more boost.

I am looking to run 20 psi till redline. So I should shorten the arm once it is installed?

See what it runs when you install it and go from there. Problem being your not gonna get a T28 to hold to redline. I have a ported Super 60 T28 and I only hold til around 6500. You can hold 18lbs til redline maybe.

If you want to run 20psi and the arm is rated up to 18psi then shorten as far as it will go. You might still drop off from 20psi in the upper rpm range but it shouldn't fall below 18psi which really isn't bad at all.

Ok, so when I install it your saying shorten it all the way to where I will have to put alot of preasure on the arm in order to reconnect it to the flapper?
