what size pulley on the original version of the novi 1K

[Cobra33]

hey guys, just wondering what the pulley size is on the original novi 1000? I am adding an 8" crank but have not read any big gains, so I was wondering what size is on the original, I know the revised novi has a bigger blower pulley
Thanks

You should be at 13-14lbs I think?!

i believe it is 3.25

Had to hood open in the garage so I thought what the hell and measured...
With the warranty/tamper cap on there it's a little hard to hold the tape right up to it, but it looks to be about 3.25" holding it up there and eyeballing, kinda crouching down. The circ. is 10-3/8 around the edge, so dividing by pi that comes to 3.3". I'd say around 3.25"-3.3". The tape didn't want to wrap real well... I'd call it closer to 3.25", especially once you account for measuring the outer edge of the pulley.
