RippinShee Posted September 1, 2009 Author Report Posted September 1, 2009 So i should keep rear sprocket stock? Ditch the 13t front and try a 14t or 15t? Quote
theshee Posted September 1, 2009 Report Posted September 1, 2009 keep your rear on and adjust from the front.. Front sprokets are like 8 bucks, rear ones are like 30. Way cheaper to do trial and error on fronts then rears. Quote
RippinShee Posted September 2, 2009 Author Report Posted September 2, 2009 Will i lose a lot of bottom end going from 13t to 15t? Why do a lot of people use taller front gears for drag racing? Wouldn't you want the 13t for more bottom end? I'm just trying to get all the info guys...thanks. Quote
theshee Posted September 3, 2009 Report Posted September 3, 2009 (edited) smaller front, bigger rear will give you more bottom end.. bigger front, smaller rear will give you more on top... people use taller fronts on drag machines because a lot of times depending how far you run, you will run out of gear and be at top speed with a ton of power left. If you put a taller front on, you will get more top speed on long runs. Edited September 3, 2009 by theshee Quote
RippinShee Posted September 3, 2009 Author Report Posted September 3, 2009 So is it more common for people to use a 14t or 15t? Quote
dajogejr Posted September 3, 2009 Report Posted September 3, 2009 Gearing is like picking the right woman...damn near impossible. Let me give you an example. You get gearing ratio by diving the rear sprocket teeth by the front. On my bike, I always ran 16/45. This is on a 10 mil cub, 300 foot only, and I'm 250 lbs. I have a 1-5 override, but I only use 2-5 for 300 foot. That's all you need. The higher the number for the ratio, the less top and more out of the hole you will have. 16/45 is 2.81 I've been trying for better 60 foot times. I lowered my gearing to 15/44. 15/44 is 2.9333 I ran the same times as above, (E.T.) but my MPH was 3-4MPH slower. So I switched, I went to 16/47 (I don't have a 46 rear sprocket, need one) 16/47 is 2.9374 Going to 16/47, essentially the same gear as a 15/44...yielded different results at the same track. Same ETs as before a little better 60 foots and my MPH is back up to where it should be. So...just because it looks good on paper, try it at the track. You'd be surprised with the results. Each bike is different, try something radically different...it might work. Quote
RippinShee Posted September 3, 2009 Author Report Posted September 3, 2009 I think im going to put a 14t front on and keep the rear stock. Ill buy a 15t front also and keep the rear stock. Ill see which one is better. Quote
