I have a nitro 4-tec 3.3 and its nick name is the beast, iv been clocked all stock by police radar gun on a street just the other night 72MPH
this car rocks the only upgrade i have is HPI X-tread tires, there the only tires that will make this car stick to the ground. this engin has so much low end mid and hi end power its truly is amazing, my buddy has the 2.5 and the 3.3 the 2.5 looses every time by at least 7-10 car lenths off the start and at top speed, the 3.3 is a work of art, i love this car the only thing i want to change is the shocks, the stock ones cant handle what this car can do.
