Pro Racing Starters Three gear reduction-type models with

custom machined billet aluminum noses are available to fi t nearly every set-up. The Pro Super-lite is the lightest (7.5 lbs.), most compact starter available. Starter has multiple clocking positions to locate the solenoid for best header/oil pan clearance. The 6:1 gear reduction offers ample power for cranking engines with up to 11:1 compression ratios. The Pro Plus is slightly heavier (10.5 lbs.) than the Super-lite, but has more cranking power for engines with up to 11.5:1 compression ratios. The Pro Extreme is used where maximum cranking power, rather than weight savings, is a priority. The Pro Extreme provides a whopping 2.68 horsepower of cranking power and is recommended for engines with 11.5:1 or greater compression ratios. Weighs in at 11.5 lbs., yet it’s still up to 25% lighter than stock starters.

Competition Engine Heater HPE4000

Warm up an engine without starting it. A warm engine has less friction loss, maintains proper clearances and has more effi cient combus-tion. Heater connects to the cooling system via an integrated check valve (sold separately). 8' long input and output hoses are included. The “rapid-heat” setting quickly heats the entire system. At 160°-180°F, the unit automatically switches to a “maintain” mode. Heater is light (25 lbs.), compact (24" x 10" x 9") and requires a 4000 watt, 220 volt connection. Electric cord not included. May be used with 110V if used with below power cord splitter.

Power Cord Splitter HPE6000

Adapts 220V to dual 110V power cord splitter (3000W only) so that the Competition Engine Heater may be powered by a 4000 watt generator with dual 110V connections.
