we threw a Alt+W/P belt on an onramp on a friends 351C Mustang, It felt like we hit a 50HP shot of nitrous...the motor really felt like it was unleashed without that parasitic drag...Why dont they put thermo-clutches on water pump pulleys?
have you ever ran a street car for more then a mile without a waterpump... thats why they don't do that, insted alot of manufacturers these days are switching to electric waterpumps that are remotely located away from the engine
