Dominator boost control
Ok so I want the Holley dom to control boost . Do I buy the Holley solinoids (pricy) or can I get a dual Mac valve set up cheaper ? Using a jgs 50 mm waste gate . Was thinking c02 bottle for pos pressure . How long will it last on the street? If you guys could point me in the right direction I would appreciate it. This is on a forged 5.3 s480

yep, cheap and crazy resolution. I have an 8lb spring in my setup and I could check the rod bearings by turning boost up if I wanted to.

PRO-TIP: You can adjust the PWM Hz in Holley in conjunction with the duty cycle for better control of the solenoid for free.
Right OMG I bought something, its awesome.

In for crazy resolution too, always looking to tighten up my boost curve. Right now with a single mac valve and Map and dome control it's usually less than 0.2 from target.

I had a small fuel supply issue that resulted in a 1/4" groove cut in my cylinder head during a mexico run. It's in 1000 pieces right now. Without a lot of fuss I was showing within 1 PSI of targeted boost previously though. I thought it was pretty damn good for a $40 4 port mac valve operating off engine boost. I know it doesn't compete with a dual setup hooked to Co2. Just depends what you want to spend money on I guess. I will say my other rig with a Haltech 2500 does extremely good with a single 3 port as well.

i fought the dual port for a long time, it was really slow to respond and the bcs dc was all over the place and never seemed right no matter what i did with the p i and d.
the 4 port algorithm that holley uses holds the gate shut during spool up and then corrects itself a lot faster than before.
its not that my car picked up power or anything, its more that i saw things reacting more appropriately to the changes i was making.
I had an ams1000 on a previous setup that was plumbed the same and it handled things way better than the holley did. i am using manifold pressure and i tried the pressure sensor at the solenoid block and also at the actual dome of one of the wastegates and it didnt seem to make a whole lot of difference.

i never said crazy resolution. i said that i liked it better and suggested trying it. we all know everyone's combos are different and i happened to decide that the almighty dual port method wasnt as good for mine. relax jabronies.
and just to clarify, i didnt buy some overpriced holley valve. i had dual 3 port macs then a single 4 port mac. i am very much not advocating buying everyones 'special' boost solenoids for $130.

And here I thought we where going to see data shots.... Like this
That is dual solenoid.... Running is actual closed loop control targeting actual boost....on 25$ humphreys
on the street running 3 seconds passes where exact and consistent power delivery is everything

I think your first issue is only using the default tab for boost control, while it works for the basics its not the limit of Holleys boost control. You can hold the solenoid closed during spool, have boost control tied into traction control and all sorts of things if you open an advanced table.

I don't have much, but if you only want a couple seconds of logs, I have that. I'm generally within 1/2 lb of my target boost. Its good enough for me. Your outright hostility is pretty baffling to me on this topic. If anyone was in here saying you needed a $400 holley solenoid or it wouldn't work, I'd get that. But there's an almost unanimous support for a mac solenoid or 2 doing a great job of boost control in this thread.
