just trying to be general, as i know there are a lot of variables, but, im running 5T tires with a 20t drive gear and 18/56 pinion/spur gear. what kind of top speed shoud i expect with a prostock 27.2cc? i'd imagine around 45-48mph? nearing 50 if fullmod?? please tell me your opinions....:rolleyes:
 
You should be in the low 50's with that gearing. With a stock 26 engine, 20t drive gear, 17/57 gearing, and 5T tires... i clocked my baja at 48mph with a radar gun.
