But now you all have me thinking so I'm going back to the drawing board. I'm gonna put my stock gears back in my Switchback and race it against the rush in 1200 feet. Both sleds will have studs. Switchback will be clutched and bikeman pipe. Then I'm gonna swap a 22 tooth on and make it a 1.68 ratio like the stock night lighting rushs come with. Then swap to a 24/40 1.67 ratio and race, then 23/40 for 1.74 and race. I'm gonna video it all so we all can see the difference on gearing. I might swap on my stock pipe back on the switchback as well to do one pass with just clutching. Luckily I live on a lake so I will be able to just drive right up in the garage make a change and go back out and race. All on the same day, same temp, same hard pack. I'll post results and video in a week or two if it stays cold guys.
