Ima get my car tune tomorrow has a 2.3 whipple with a 4lb lower n Ima put a 2.75 pulley for my race tune anyone know what's size belt I need n how much boost and power Ima make?but most important need to know what belt do I need
That setup should make around 25lbs. Theres a belt guide on here that should give you an idea on the size you need. On my first generation whipple my belt is a Gates K080790 That is to run a 2.75 upper with 4 lbs lower with a snub idler. I believe it is 78 inches. What fuel you planning to run with how much timing then we can guess the power you should make?
