have a Mech Tech turbo system for under $5K? Superchargers just plain suck. No boost before 4K, weak torque, parasitic HP loss, can't control the boost, belt-driven problems, etc. The turbo is obviously superior, but I have yet to see someone post anything about Mech Tech or a system they recently installed from them. I guess people are just stupid and like giving INCOMPETENT shops like RMS business for a product that flat out does not perform. Ever seen a supercharged race car that actually won anything?
