Thinking back on my strip runs Friday,I had added a KN filter and a fairly effective ram-air setup. Going thru the traps in 3rd gear gave me a 99.7 MPH. That's about what a stock Bullitt will do I guess,though some have gone over 100. So I would think that I should have seen a slight improvement in the speed. I tested the ram-air with a leaf blower,about 3ft. from the front end,and got a healthy flow of air out the throttle plate end of the air duct,past the MAF. Maybe a chip is needed to show an improvement.
