I run the Viair 1000 kit and a single 3-port solenoid. I can target 40+psi with a 3psi wastegate spring.

yea I know, I’m trying to weigh out all of my options now. This project has gone from an NA little ripper to a “race car” at least in my eyes

OR WG duty VS wheel speed would be my preference.

Im a newb when it comes to turbo cars now. Back when I was messing with turbo nissans, we used an eBay manual boost controller and an SAFC-II to trick the MAF for fueling circa 2006. So much has changed I’m trying to get a grasp on it

this is what I want in the end after doing a little research. Why did you go single MAC valve vs 2? Reason I ask is the way motion race works sells their kit is with 2 MAC valves. It appears one feeds the compressed air to the WG’s and one vents the air as a control

While it works I can't see ever only needing 3lbs of boost, if anything goes wrong on that system you are stuck with a turd of a car. Unless you have it setup properly to pin the gate shut until max boost, might be why your spool is so slow as well.

I prefer simple setups, especially for street cars. Even on race cars I've seen people chasing problems with C02 leaks, empty bottle, forget to open bottle, etc that simply don't exist on a basic manifold referenced system.

2 is for more resolution/control. Its not needed IMO unless you are competitively racing. Same with a 4 port VS a 3 port. Though if plumbed correctly a simple 3 port will give the same min/max settings as a 4 port, or 2 separate valves. The area in-between the min/max just has more control.
