sirio vs ofna vs O.S

[tootallpaul]

Three motors I'm looking into Sirio .27 Ofna.26 O.S 28VG
this will be going in a Tmaxx, anyone put one of these in there's?
do you wish it had more power or was it more than enough?
whats the better motor as far as staying tuned, longivity?
Thanks Paul

go with a os.21tm lots of power

o.s!!!!

os .21 will tear out your gear if slipper is not loose enough. a .28 will kill your diffs and drive line. you will spend more money hopping u truck up or repairing it with those larger engines

The 3.3 drivetrain is built to take big block power. It'll handle it no problem as long as your slipper is set properly. You may need some metal center drive shafts but that's about it.
