I too have been racing and building race cars and engines for many years. I'm 53 now and started racing 1/4 migets when I was 6 in So. Cal. I also raced full midgets and prints @ ASCOT park in Gardena, Ca. (Now closed) from 1967 until I went into the Army in 1969. My open wheel racing career ended in 1972 after I wriecked my sprinter in York, Pa. and ended up in the hospital with a spinal compression injury. The Army gave me a choice to continue to fly or continue to race but that they would not allow me to do both. So I became a tuner and builder, on the side, and continued to fly helicopters in the Army. I have also gone tons of drag racing and now autocrossing..... Now you have my RESUME.. :roll: As if any of it matters. :roll: You have your opinion and I have mine.

What the filters do is allow the engine to get more unrestrictive air flow "over the stock" filter and provide the hp that is taken away with the more restrictive stock filters. If you want to argue with that you're not going to do it with me.
