What would be the next 2 closest possible gear ratios above the 25/25 set? My tans has the 25/25 in 3rd and I'd like to have the availability of simply switching gears for longer tracks instead of changing sprockets and chains.
Has this been done before....surely it has.
Setup is a BP class, built Intek twin, 8/5 pulley, BoNewCo trans (15/35-1st...23/27-2nd...25/25-3rd...no 4th or 5th), 15/44 sprockets and a 49" rollout....6400ish rpm. The sprocket setup is a baseline for now that hasn't been tested (5.75:1 final)....I'm thinking it'll be a little tall, but I can change it easy.
According to my math your at 5.50 final ratio not 5.75 which is way to tall,should be closer to 7-7.25 to 1 final ratio running in 3rd gear
