//13° MBE - SPRINT

DESCRIPTION:

Based on MBE’s race winning 13 degree cylinder head, the MBE Sprint is modified to optimize this head specifically for Sprint Car racing. In fact, the 13 degree MBE Sprint outperforms any Cup-style SB2 cylinder head.

 

MBE’s porting program for this head has reworked the port cross-sectional area to take advantage of the unique nature of Sprint Car racing engines running alcohol and mechanical fuel injection. Although popular opinion holds that engines running alcohol fuel require the largest ports possible, after extensive R&D MBE found that a slightly smaller port actually improves both velocity and power. And to match those ports, the valves are sized at 2.230 inches on the intakes and 1.600 on the exhausts. The ports offer a measured flow of 425 cfm for the intake ports and 280 for the exhausts—and remember, MBE is the only cylinder head specialist that guarantees its published port flow numbers.

 

Besides the redesigned and optimized ports, MBE has also relocated the spark plug location on the Sprint heads to make sure the alcohol doesn’t wash the plugs. There’s also a lightening program available that cuts eight pounds off of a pair of heads, which is a huge advantage in Sprint Car racing where teams often go through great pains to cut every possible ounce off the chassis. This is a cylinder head that not only makes great power on a Sprint Car racing engine, but also produces a wide torque band for fast restarts and great acceleration coming out of the turns.
