    Turbo Speed sensors are critical in accurately identifying where your engine is operating on the compressor map + how fast the turbo is spinning. Traditionally, turbo speed sensor installations were difficult for the end user - requiring complex machining at a compound angle to carefully hit the contour area of the wheel bore - and at the right angle.

    BW's Speed sensor solution provides this precision machining already done to every EFR compressor cover. The hole stops short of the protruding into the compressor wheel bore. If a user decides to buy a speed sensor as an upgrade accessory, they can remove the compressor cover and extend the hole the rest of the way through to the wheel bore using a simple hand drill. A 1/4 Drill bit is all thats needed and the length/depth is very short. This hole allows the top of the sensor to come flush with the contour surface. The hole does not have to be precise as no sealing takes place in the small hole that the user just created. The hole must be deburred where it pierces into the wheel bore. The goal is to make sure that there are no sharp edges remaining in the wheel bnore that the compressor can become caught on. The speed sensor is powered by a +5V supply and the return signal is a variable frequency square wave that has maximum amplitude of 5V and has a 50% duty cycle.
