Iky Posted May 30, 2014 Share Posted May 30, 2014 Hello, Since taking the Supra to BPU, i've noticed that on more than one occasion the boost has spiked to over 1.4 bar. I have a restrictor ring which should really be capping it off at around 1.2. So hence, I think I require a boost controller. I'm not after anything flashy, all I want it to do is simply keep the boost at a safe level and do this reliably. Looks do not matter as it will spend most of it's time hidden from view. What would you guys reccomend that fits the bill? Quote Link to comment Share on other sites More sharing options...
Scott Posted May 30, 2014 Share Posted May 30, 2014 A ball and spring MBC. You'll need a smaller restrictor ring though as the boost controller ain't going to do squat if you're already seeing over the limit you want to hit. Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted May 30, 2014 Share Posted May 30, 2014 A boost controller can only raise boost, so if it's spiking, you may need a smaller restrictor ring. Think mine is 2" from memory. I have a gizzmo msibc sitting here, that I was going to install, but it illuminates blue, and being a tart, I want something red! It came out of my mr2 turbo, and works perfectly.

Branners Posted May 30, 2014 Share Posted May 30, 2014 If it is spiking then fit a smaller restrictor ring to bring the boost down, and then use the boost controller to raise it and have more control. I'm still a huge fan of the SBCID and Powermeter combo. Boost mapping based on speed, adjustable enough to give you what you need without the need for a degree in maths, and theres even a thread on here with recommended settings. I will buy that combo for my car one day, just waiting to hoover up a good value one. They do a more recent version as well (sbc colour or something) which should do the same stuff...

Nic Posted May 30, 2014 Share Posted May 30, 2014 Contemplating the smaller rr and ball&spring route. Cheap and easy. Thankyou all. There are advantages in fitting a good quality electronic boost controller, they can make a significant difference to how quickly the turbos spool up and can help maximise boost through each gear.
