Maybe we should ask our boy racers - they are the experts in intercoolers that can get eleventy bazillion horsepower out of a 1.2 corsa
I doubt any boy racer has ever fitted an intercooler. Aftercoolers maybe, but not intercoolers.
The System we are talking about is not about getting gazillion horsepower, it is about huge fuel economy improvements, something boy racers also know zip about!
