nice testing... hallman just released a heavy spring tho about 1 month ago if you call them up and ask they will send it to you for free im sure. id like to see what the difference is in the springs.
and ya Dave: you did ALOT of testing.. especially on intake manifolds (which are a ***** to take off and on) and intercoolers and other things.

Boosted...So this test was done with the Hallman using the softer spring and ceramic ball?? I think you would see different results testing it with the steel ball and stiff spring like I said before...

Thank you very much for the testing, the effort and adding in the RPM vs 20 psi target.
I took the average of each of the three runs for all three points you tested and posted for each controller. They are all very close, much closer than I thought they would be. Based on your testing the Forge wins the testing. Which spring is in the Forge, light or heavy?
Doing testing is a pretty thankless job, I've been down this same road for probably hundreds of tests on here. I appreciate you adding to the good information that's posted here on the forums.

The FORGE is running the heavy spring.
I do not know the specifics of the Hallman. It was provided by Project Skyline. Hopefully he know exactly what model it is and what spring it is running and can chime in.

funny i had it replaced by forge. and the new one also gave me trouble a few months later. a friend of mine bought one and had the same trouble. also do a search on here. its a common thing ''when they came out''..... maybe its been revised i dont know. i threw them out and wont buy them again. im not looking to argue i was just stating the issue's i have had with a part you tested.

heres a hallman pro rx with ceramic ball and stiffer spring (not the newest stiff spring)
on my car with the br 2.3 and stage 3 head and fp black .. exhaust manifold is ported so is the turbo.
temps were 75f, wastegate is a 25psi actuator preloaded to hold 29-30psi.
i have noticed the hallman control is very sensitive to turns of the knob.. if not turned just right it bleeds off excessively.

I would say the boost you are holding up top is due to the wga spring/pre load.
Connect your boost source directly to the wga and it will still creep to something close to 27psi at 7000rpm... I don't think the mbc is adding much in this case

Thanks for the testing. I've used the hallman for a while now and like it. I think I will be going to ECU controlled boost though as to get 16 psi at 7000 RPM, I have to spike the boost to 27 psi on the IX turbo. ~27 psi on the IX turbo and 91 octane is a little tricky on the tuning side and doesn't really drive that smoothly.
With ECU controlled boost, I can kill that spike and hold better top end. Just need to find a high pressure WGA...

I personally like the Perrin in-line. I had a Hallman for a long time after chucking away my electronic 3 port back in 2004. The Hallman has been nothing but reliable. But like previously mentioned, you had to make sure you had it twisted just perfect or it would bleed excess boost. I don't know how else to explain it than you give it a quarter twist, it would spike 24 psi but only hold 19 up top, twist it up a 1/4, come back an 1/8 and it would now hold 21 psi up top. Very frustrating.
The Perrin in-line is straight, set it and it is consistent. No more twist turn, test, twist turn, test, and repeat.
I was hoping the GrimmSpeed would beat the Perrin/Buschur. Guess I'll stick with what I have.
