I have been reading up on many engines and tuned pipes for the new Serpent 733. Everything from the RB T-9 series, Picco red dot, Maxx Power, O.S., Mega, and Novarossi Engines. I am in Afghanistan right now and havent been seeing what guys are running except on the forums. I am leaning towards the RB T-9, but have some of you 733 owners been running. How have the different motors been performing for low mid and high end, as well as the car being able to handle some of the modified motors?
