We have had factory drivers reach 74-75 mph at 301 raceway in Maryland. The highest pinion you can run on a 8 scale car is a 21 tooth most guys use 19 tooth and some used a 20t at the 2009 worlds last year. Race in the amain with some 8 scale cars and you will be blown of the track. Take to factory drivers one with a a 8 scale car and one with a 10 scale car. On a large track the 8 scale car will put laps on a 10 scale car in a long main. I race like 10 scale I have a tamiya 416 we, nt1 ec and kyosho m3 evo. I race 10 scale because there are more people that run the class because 8 scale is either to fast pace or expensive for them. 8 scale Cars have more cornering speed, more acceleration, and slightly more top end speed than a 10 scale nitro car there is no comparision. Nobody gears there 8 scale with ral
tall gears even on the largest track we only run a 19t pinion. Paulo was clocked at 79 mph before at the at 301 raceway. The fastest top speed recorded for a 10 scale car were 65mph by Vincent Jackson with a jp eagle tl3-t and Murnan at 65mph with his rbm3 which was a prototype at the time.
