Message displacement and rpm and is about 200 cfm per side at 7500 rpm. The intercooler can increase the flow by up to about 20% on the hot side, but the flow is still the same cfm as the stock engine. Increased hp is made by increasing the pressure of this volume of air, and pressure drop decreases as the same volume of air is moved at a higher pressure.

Significant increases in cfm are before the turbo compressor, and from the exhaust valves through the exhaust system. This is where increases in size are most useful.

We need someone to sell larger ducting from the dual maf to the compressor.
