Summit® lightweight Nippondenso-type Protorque starters offer a 4.0:1 gear-reduction ratio and a whopping 1.9 HP. That's 222 ft.-lbs of racecar cranking power. If that's not enough, there are even more powerful 3.1 HP monsters, which are a pound lighter! They have a 4.44:1 reduction ratio and churn out an awesome 342 ft.-lbs. of torque. Both of these powerhouses are suitable for engines up to 502 c.i.d., and compression ratios of up to 18.0:1. GM versions are adjustable for five mounting positions; Ford types, for 18. A gold dichromate finish prevents corrosion and electrical shorts on both.
