Just got this email from Mr. Crawford himself:
Crawford Billet Power Blocks
While doing the R/D on a custom intake manifold for the BRZ/FRS market, we stumbled onto a way to create the same power increase at a fraction of the cost. We call them our Billet Power Blocks or BPB.
CNC machined from Billet 6061 aluminum, our BPB sandwich between the cylinder heads and the intake manifold to create longer intake runners. The lengthened intake runners enhance the volumetric efficiency of the engine which translated into an increase of 19 Horse Power, 15 Pound Feet of Torque and narrowed up the torque dip by 300RPM on a totally stock BRZ. Our BPB also works with any aftermarket tune, exhaust and intake components. Our original road testing was done in conjunction with our stage 1 reflash followed by extensive dyno testing with and without a tune.
Our BPB kit consists of 24 pieces that make it a complete bolt on system which can be installed in under 30 min. In the kit you will find 2 BPB, 4 Delrin O-rings, 11 mounting bolts, 1 nut, 4 fuel rail shield risers, 1 support bracket for the direct injection control unit and 1 support bracket for the removal of the 7 pound fuel rail shields for you Race rack guys that are removing weight.
Crawford stands behind this product with a money back guarantee.
