30mph? How?

Running my excel sheet says that you'll top out around 33 mph in second gear. You just got the wrong gearing. However, if you go with an 18 tooth or 20 tooth, you should be around high 30's and if you go to 22, you'll hit 40 then. However, when you run a pinion that large, you'll easily draw 100 amps or more in second gear so be careful. I end up running mostly in first gear when I have large pinions.

BTW, the radar gun is very accurate. I have both radar gun and GPS and they always give me the same number.
