The Harrop car will beat the FBO car, but lose to a car with a centrifugal kit that costs the same as the Harrop kit. Like people have said, in daily driving the positive displacement blower produces more torque sooner — it’s all in before the centrifugal has even started making boost. Be great with AWD for better traction. The best recipe for power with a small V8 in the 4L range, though, is twin turbo, which is why BMW, Audi and Porsche are making them.
I’d still take the VT650 kit over the Harrop for an E9xM3. But when I buy another used performance sedan it will be twin turbo V8 with AWD.
