I am new to tuning a turbocharged vehicle, or anyvehicle for that matter. How does a boost controller work? My car's boost and turbocharger is all mechanical and I'm prettysure the boost controller is electrically controlling. So my question is how does it work and would it work on my 20 year old car? I plan on getting a Racingbeat turboback exhaust in the winter that adds 59hp!!!!!!!! But that added horsepower comes from upping the 6psi boost to 15psi by relieving backpressure. If I had a boost controller could I put it back to 6psi via a nob, switch, button, or laptop interface, or something from the inside of my car and turn it up for track racing? If so I'd be interested in purchasing a unit from Tunerfix. Thanks.

In simplest terms: It prevents boost pressure from opening the turbo's waste gate until the desired preset boost level is reached. Inside the valve is a precision stainless steel ball that is held in place by spring tension. During the turbo's spool-up (as pressure is building) spring tension in the valve is greater than the boost pressure pushing against the ball, so the ball prevents the air from flowing to the wastegate actuator.

This maximizes the efficiency of the turbo during the spool-up by using the greatest amount of air possible to spin the turbo charger. Most boost control systems waste air by venting much of the air out, even many factory boost control systems waste available exhaust energy during this crucial spool-up period. Once the turbo spools up to the desired boost, the Boostvalve opens, quickly opening the waste gate. Boost pressure is held at this level with accuracy unmatched by even more expensive methods of boost control.

This is a manual boost controller. Yes, it will work on your 87 Turbo II. In fact I have a kit for your car. If you go onto TunerFixx.com and go to the webstore you will see the kit available under the Forced Inductions category. I don't recommend running the controller inside the car because the longer the hose to the controller the more lag you will have. The shorter the better, unless you go expensive with the electronic controllers.

As far as switching from a high boost setting and a low or stock setting, I carry setup that is a switch that allows you to do that as well.
