INTAKE
:lol: YOUR RPM AND POWER RANGE WILL BE THE MAIN FACTORS. SHORT RUNNERS FOR HIGH RPM. LONG ONES FOR LOW END POWER.VOLUME OF RUNNER WILL SET POWER RANGR. CROSS SECTION OF RUNNER WILL SET TOP RPM..INLET RADIUS ON EACH RUNNER IS IMPORTANT, NO SHARP EDGES. ABOUT 5/8 RADIUS IS GOOD ALL AROUND..STRAIGHT AS POSSIBLE.NO CORNERS OR POCKETS TO HOLD RAW FUEL..
