....So to recoup, the chargecooler is like a heatsink - it absorbs the temp spikes when they do appear and gets rid of the load once the boost is no more. If you're on a race circuit full throttle all the time, remember that there may be no chance for it to shed the load. Not much use after the first lap, dead weight mostly! http://www.max-boost.co.uk/max-boost/intake/intercooler_C20LET.htm#isfmicbetter
