Grimmspeed Manual Boost Controller
GrimmSpeed introduces the most refined Manual Boost Controller available on the market. Our Manual Boost Controller allows you to raise the OEM boost levels in a quick and efficient manner. Adding the MBC will result in Quicker Spool Up, Quicker Response, Increased Horsepower, and Increased Torque.
Innovation is the standard here at GrimmSpeed and we have continued to push the envelope with this product as well. We have created a MBC that only requires one spring for both high and low boost settings! No more changing out springs! Our spring offers very fine adjustability...we have achieved this by creating an extra long spring and large adjustment range with a very fine threaded adjuster. The spring will outlast the car as it is made from Stainless Steel. Unlike the competition who uses heavy steel balls, we have used an UltraLight Ceramic Ball that will react much quicker.
The Bleed Port isdesigned to precisely and quickly bleed off wastegate pressureso the wastegate closes quickly while not being large enough to affect mass air flow readings during high boost. It is also designed to further dampen boost spikes. Boost ranges from wastegate pressure to over 35PSI are obtainable if needed yet it still offers fine enough adjustment to only raise the boost in very small increments.
Works with any turbo application including Subaru, Mitsubishi, Hyundai, MazdaSpeed, and many more.
