MSD's DynaForce Starter is built to crank over high-compression race engines even in extreme heat. A three horsepower motor drives a reduced 4.4:1 gear set for strong torque at the ring gear, while a downsized housing clears most headers and oil pans. The billet mount can be clocked to different positions for tight header clearance, and the assembly is powder coated to hold up underneath the car.
