IE Billet Manual Boost Controller
The IE MBC is an easy to install compact unit, less than 1 ¾” in diameter and 3.0” long that can be custom installed virtually anywhere in the engine bay. To make the IE MBC even more universal, each boost controller includes a stainless steel mount bracket with hardware and ¼” hose barb fittings and three feet of matching silicone hose to make installation simple for traditional turbo setups.
SIMPLE CONNECTION GUIDE
With some careful engineering, we were able to design this unit to be adjustable from the base wastegate pressure to 30 psi+ without having to swap internal components for higher boost setups. That means the IE MBC is truly a one-size-fits-all unit and can be used with nearly any aftermarket turbo setup. Many boost controllers available simply bleed off boost pressure to the wastegate, which works to bring boost pressure up, but does not eliminate the wastegate from partially opening before the desired pressure is met. This makes for slower spool time and spiking boost pressure. With boost spikes, power delivery is not smooth, nor is it held until redline. We designed our MBC with a ceramic ball and a spring, so you can expect boost control to be linear and smooth with no concern for spiking. This style of boost controller does not allow any boost to the wastegate until the desired pressure has been reached, keeping it completely closed up until that point. Quicker spool time is seen due to that, making more power early on. The IE MBC uses a ceramic ball versus a steel ball, which can move much quicker and let boost through faster due to the material being lightweight when compared to steel. It is critical to have the ball move quickly, as it makes boost control nearly instant and keeps the boost pressure consistent.
