are there any electric boost controllers that can work two turbos? If so who makes them and where can I get one?

just wondering

thanks marty

what do you mean?? do you mean controlling boost seperately between turbos? if you just want an ebs for the whole tt system there are many out there. the greddy profec-b seems to be the most popular and most liked.

 

better question, do you need a special boost controller if you are running Sequential turbo setup? I know now they make Sequential boost controllers but are they needed?

 

Knightsports EBC III. Love it. It's not as fancy as some, but it does a great job controlling boost and it was a SUPER easy install.

Very simple and straight forward. Simply set the boost you want and that's it. None of that guessing with the duty cycle crap.

 

Most people just attach the boost controller to the wastegate, which usually works to control boost in a sequential system.

I have two MBCs on my car - one attached to the wastegate and the other to the precontorl line. However, despite a lot of experimenting I could never get consistent precontrol regulation of prespool.

You should be fine with one.

 

While there are two turbos, there is only one wastegate. Most people go with the Greddy Profec series. I would suggest the same as there is plenty of information on installation as well as configuration here on the forum.

 

i got the greddy type s on ebay for around 100 cheaper brand new,, and it works great

 

What about the boost control on the Power FC, which controls the stock solenoid? Is that any good?

 

Since it's using the same mechanism to control boost as the stock ECU, it just as good as stock (which isn't all that great).

 

Yeah, but you have custom solenoids. If someone is running on stock solenoids and using the EBSIII, you can only go so far with moding before it becomes unreliable since it works in conjunction with the factory setup which isn't too great.

 

I'm using Saxyman's first set that he ever made, actually the ones he built for his car, which did not include the wastegate and precontrol solenoids. Control on the stock turbo control soleniods are amazing. All that was needed was a well researched and tested system.

I do have a ported wastegate though too but that was needed due to the open exhaust without a cat and free-flowing intake.

 

in other words I can use one manual one to control both??? sweet!!!

 

wait I thought there were two wastegates in the seq setup? so damn, I am lost.

 

Just one. There is a prespool gate on the primary turbo which directs some boost to the secondary turbo before transition, but this is not a wastegate per se, though it does operate in somewhat the same way.

 

If you're going to get a Greddy ebc (which I recommend), go with the old school profec b or the new style spec-s. Stay away from the spec 2 (digital).
