Just got it broken in today. Oh man this engine is just what I was looking for. Enough grunt to raise the front tires if I want, but manageable engough to control in the turns and keep off its back. Like posted the truck has the OS .21TM engine in it, along with the P3 Rockers and rods, R tuned pipe, Motor saver filter, AEM front arms, (soon to have the rear kit also) and the HBZ crash cage. (keeps the cooling head safe. I've broken a couple engine mounts...) Next up is going to be a new radio system, stock one has been on the fritz as of late.
 
I'm looking into buying me a OS 21 tm for my revo but heard that the resonator an the std pipe is no good with this motor. What pipe wil you guys recommend and how does this motor compare with the trx 3.3?
 
I have the R truned traxxas pipe. Works fine I just had to angle it a little bit to be sure that the OS 21 manifold made a good seal with the pipe. You shouldn't have any problems. The OS 21tm has a better powerband and more bottom end power, but I think that the 3.3 has a little more top end. Over all I think that the os 21 is much better, but its not like you will be getting so much power you'll flip the truck every time you lay on the gas. But don't worry it still has the balls to wheelie or flip the truck on occasion. I hear that the trinity pipes work better than most on this engine tho... you might want to look into it.
