we have about 6-10 crts every friday night at our track. i have noticed which ever engine anybody runs at 1/2--3/4 down the straight(90ft) the gearing takes over and all of the trucks are dead even. we have almost every possible engine in theese trucks and i dont see a huge difference in any of them. the stock motor seems to be as fast as my rb with longer run time. to me the sirio evo seems to be the quickest, nobody has an .18 in theirs yet only .12s . for the money os tz seems a good choice. most modded engines are modded for fuel economy and smootheness not power.
hope this helps
joe
