5 to 10,000. Had 62's when I picked it up. Took the air horns out and added the slp air intake, put the can on and had to go to 64's which were unusually heavy for my altitude. Not sure why my sled ran so well. Many including Brad from Power Addiction say the air horns help it to breath but all I saw was that the end of one of the horns wasn't much bigger than a quarter. It's an old argument but I'm siding with more air openings on both ends of the motor.
