RE: D8T + Novarossi N21BF??
i have the D8T and the nova BF21 and they will work, im not currently running that engine in my truggy, just not quite enough power for me. but if you do run that engine, buy the O'donnell cooling head for it, odonnell 99 plugs and an dynamite 053 and it will be a good club racing engine, it lack a little on top but its worth the money to race club races with it. and the O'donnell make a HUGE difference in power, it will run alot cooler.
