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.
