4.1 Limited Pro question November 17, 2010 12:16AM
Thinking of stepping up from super farm. I was wondering how much fuel it takes to spin a 4.1 with 640 cubes. Also what size nozzles I will need? Thanks for any input!

You need between 900-1000cc with 5-30 to 5-35 nozzles depends on head flow and cam setup. Call some of the guys that have been running this class for a while. They are a great group and always willing to help.

once you switch that tractor from a super farm to a limited pro youl never go back to super farm.

1050cc works better!

It all depends on your setup. The best way to find out is by tuning on a dyno....best money you will spend
