blowers can run intercoolers, too. But intercoolers effectively increase compression by cooling the air. Everyone that runs a blower not from the factory is flirting with disaster... heck, you're flirting with disaster by sitting on 15.7 gallons of gasoline coursing through a 4000*F engine hurling 3 feet from oncoming traffic that would equal the force of 140mph upon collision. Give me a break. It may not be 'optimum' but that's hardly the point. I'm pretty sure that this Karmann built German engine is stronger than a Honda B16A 4-cylinder.
