I've seen them run, and although it will do 50 MPH, their acceleration is somewhat slow compared to a StreetForce. In a "headsup" race, the StreetForce will be faster and have much better acceleration. If you want your 4Tec to really move, install a NovaRossi engine. It will really scream then! Don't waste your time and money on the small mods, just get the NovaRossi. BTW, if or when you do, get some extra one-way bearings for the two-speed transmission. With the additional power of the NovaRossi, the bearings (weak link) will fail on a regular basis. The bearings cost around $20.00 each. High performance comes at a price.
