Which boost controller?

[sporadic]

Which boost controller do you use, and which would you avoid? Up to now I have had an internal wastegate that I adjusted with a turnbuckle. Now I have the GT2871r with a 38mm Tial external wastegate and need manual adjustment.

Should I go manual or electronic? Let's assume cost is not a concern, but I obviously don't want to spend more than necessary.
I have the tools and skill to make one myself, but I mainly don't want to play guessing games and spend 20 hours finding the right tension spring, dialing in the boost, etc.

I was looking at this: TurboSmart Dual Stage Mechanical Boost Controller

I don't daily drive this car, and I won't be adjusting the boost frequently after I set it. I will adjust to to around 10-12psi for now, and then as high as 20-25psi after I build the spare motor.
My thought with the dual stage is I could run 12-15psi around town and have a setting for 25psi at the track, which I could flip (manually or automatically) after in 2nd gear.

Thanks all

I am not a fan at all of the turbosmart products , if thats your choise there is a killer deal on a new on on ebay for 119.00 right now in blue

I like the very hard to find Greddy type S but NOT the specII type S

If money wasn't a option i would figure out how to wire up a AMS-1000 unit, but its not realistic lol. I like my greedy type S i put the hi/low boost on a button so in second gear i run around 12psi to hook then hit the button in 3rd-4th are 18-19psi. simple to setup and cheap boost controller. I do like the HKS EVC also.

Yeah I saw that deal.
Do you not like them because they don't hold boost properly or spike?

I hear an echo, lol. Thanks, looking into those. A guy on Steel City Stangs also recommended the AMS-1000 if price wasn't a concern. I think that might be a bit extreme for my purposes.

I went with a TurboSmart dual stage mechanical. I will let everyone know how it goes.

std mechanical would of been fine

I wanted the dual stage for the track. If the manual switch is inconvenient while "in the moment" then I'll rig up a timed switch so it will switch to full boost after x seconds.

This is the boost controller I went with:


I bought it open-box from ebay, so I wanted to make certain it wasn't busted up so I took it apart. This is what is inside. This one is indeed new.








For those wondering how this works, it is a bleed-off type boost controller. That means it will bleed off a preset amount of air going to the wastegate.
This controller has two stages of bleed-off, controlled by a switch. The only electronic part in this system is the solenoid that opens the path to the second bleed dial. It appears it would work fine as a single-stage without any 12v signal.

The dials are reverse threaded. Turning counter-clockwise closes the bleeder valves. Turning clockwise opens the bleeder valves to increase boost.

I have not installed this yet. I ordered a vacuum block and it won't be here until later this week. I'm going to clean up some vac/boost lines so my boost gauge, boost controller and bov all get the signal from the same vac block.
I'm going backpacking/flyfishing for a few days next week, so don't expect any updates until after.

I wish I had the greddy type S
