For further insight, no matter how the intake charge is cooled a key aspect to the reliability and performance is the efficiency of the cooling = eventual heat soak not evident until after a few pulls back to back. If the water in the water cooling system is not circulated properly, stagnant, or uncooled water will continue to flow and therefore not provide efficient cooling. This is why we designed our water hoses with a certain diameter with insulation, with proper high quality fittings, factory grade heat exchangers aka radiators (pictured above), and a Bosch water pump to ensure proper circulation.

You can do all the pulls and hard driving you want on the street, but the heat build up and abuse the s65 motor takes through 1 mile on the track at speed has no comparison unless you drive full throttle 100% of the time on the street

Based on highly efficient cooling and proper tuning, the s65 has held up pretty well to F/I even on the track
