Boost Controller

vbmw335 · 06-30-2008, 10:21 PM

Just curious...why cant we use a boost controller like this on our cars?? with v2 i routinely see spikes over 17psi ...with something like this boost controller it will have safegaurds to decrease boost in the event of overboost.

can someone provide more technical insight to using devices like these on our cars?

Thanks.

I've always wondered the answer to this one myself.

The boost control is vacuum operated so traditional pressure cracking MBC's cannot be used. The natural state of the wastegates is open. The solenoids are cycled to use vacuum (from a vacuum pump) to close the wastegates in order to build boost. This is quite a bit different than boost controlled wastegates.

This I copied from the following thread....
