If I hold a steady 30MHP in 2nd gear and "floor it" the power between 5000rpm and the redline is noticably better, even the wife commented on it feeling stronger. 3rd gear feels stronger on the change too.
My intention was to get more "cold" air in rather than just "more" air. I understand the 2 straw principle, but the inlet into the std airbox is over size already and capable of more then "stock" bhp by far. I was only interested in inducing more "cold" air by mixing it with the current air being drawn in. At speed I am sure I will be getting more air in too, but the main thing is the power delivery in 2nd gear alone was with the time to modify it
