I looked in the archives for a formula for the square inches needed for a air cleaner surface,no luck
Do any of you know if there is a formula based on HP and if there is what it is? The reason I'm asking is I'm getting ready to dyno test a motor and I want to test several different intakes and carb combination with the air cleaners on, including a tunnel ram with dual carbs, 4150 and 4500 Holleys I have several nine inch daimeter 4150 air cleaners assembly but no small diameter dominator air cleaners yet, I want to order the nine inch diameter dominator air cleaner but not get to tall of ones that won't fit in the hood scoop on my tunnel ram hood or order to short either
EDIT: I called K&N on Monday and talk to oneof there tech guys, he gave me several formulas for figuring out how much surface area is needed based on C.I. and RPM (like already posted on one of the comments on here now
) and how to figure the area on the round and falt filters. Now I need to dyno the motor to find out where it makes peak power and go from there, once I know the results I wlll make sure the surface area is bigger than the minimums suggest by the formula. It looks like, based on past motors with simialr C.I. and peak power RPMs, that two nine inch diameter by 4 inch tall with the Extreme lids will be more than enough surface area, time will tell
My 512 six pak motor made 8 hp more by adding a second six pak element on top of the first on back to back test. that motor made the most power with no elements on the air cleaner base, not much but more(2 to 3 hp maybe, I can't remember the exact amount now, that was in 2003.
Thanks to all for your help
