have a 4 tec with a 3.3 that i just had a stage 3 race modification done to by dadders.net. I am trying to get it to go as fast as i can in a straight line. These cars aren't very great handling anyways. I was wondering how fast you think it can go and if anyone knows where i can get taller gears than the ones from traxxas with keeping the stock tranny set up? They said the engine will be able to rev up to around 45,000 rpm and have about double the power as stock so i know it has plenty of power, probably too much for the car, but i have been told with the stock gearing it will probably do arond of not upwards of about 80 possibly close to 85. With the stock gearing anyways. So any help with finding any taller than stock gears for this car or suggestions on the topic would be appreciated. And don't turn this into a bashing thread like people do to all the other ones similar to this. Just informative positive feedback only.
