Test Vehicle


Pete Jauker (owner, Pete and Paul's Porsche Shop), sends car owner/driver, Peter McCarroll, on test laps at Willow Springs Raceway, CA. Lap times are in 1:22's. Car runs in POC and PCA events on the west coast and midwest events.

Owner McCarroll wanted a system to ensure adequate cooling needs when running in extreme race conditions. For example, Willow Springs Raceway, a local track, is located in the high desert area in Southern California where summer temperatures are typically over 100 degrees. Seine Systems installed a prototype MPC misting system to reduce intercooler air temperatures and a branch system to provide cool air for the brake ducting system. A side benefit is that the lower temperature intercooler air also reduces the air temperature for engine cooling.

Despite less than ideal ambient air temperatures (a cool 60ºF), the before and after intercooler temperature reduction was 15ºF. Higher ambient temperatures should result in faster rates of evaporation and increased heat absorption.
