Mr. Hack,
Was wondering if you could explain why reducing the length of the intake runner and reducing the backpressure of the exhaust side of the head (installing a header) will reduce the low end torque and move a specific torque and hp point to a higher place on the rpm curve.
From a stock setup, decreasing back pressure and reducing inlet length makes horsepower, but a point is reached when this process becomes detrimental. Engine firmware is not the problem. The solvencies for such a problem is to perform headwork. Port, polish, deshroud valves, camshafts, larger valves, etc. Yes engine management is crucial here, but not the bottle neck.
The question is how does this breakdown explain itself due to intake and exhaust modification
Razzmatazz
