I guess it depends on what your comparing it too....My buddy has a CRF .21 that I modified that replaced this engine and there is no contest, the CRF smokes the ass off this engine in every way shape or form.. However my modded Picco's and CRF's are insanely powerful engines so its not a fair comparison......

Looks like a one armed, one eyed, Dremel bandit got ahold of it.

LOL @ mblgjr That's what I thought when I opened it up.

To be very honest, my Clocked CRF .21 powered RC8T will smoke the doors off this Nova in my RC8. You have to see it to believe it. And it gets better mileage. When the Nova was in my truggy, I was running stock gearing (14/54 ) but with the CCRF, I run 14/50, and it's still much more punch/power than I could ever get with my Nova. The Nova would get about 8.5 minutes with any pipe I tried with it, give or take 10 seconds. Here's a picture of my tank, after the final 7 minutes in the A Main at the Canadian WinterNats 2009, running the CCRF .21 :




Ask Maximo how much power I had, it was outrageous. I love it. I'll be sending my Sirio over to you as soon as it gets here dude

Honestly buddy I almost felt guilty watching you struggle with the CRF.... The track was much slicker then I anticipated and that CRF is definitely more for high bite surfaces..I am positive that CRF will be right at home on your local track, you guys have a great surface and you should be able to hook that monster up... That modded CRF is definitely one of the nastiest .21's I have ever seen run, I definitely got some chuckles watching you try to tame it !

LOL, yes, it was a beast alright, but I also have to learn to ease into it better! The funny thing is I'm still running the extra head-shim dude. It looks like I'll be keeping it in for now Oh, and don't feel guilty, power is what I asked for..it's what I got, and I love it. It was my first truggy race, so give me some wheel-time with it, and I'll get better...I can't wait till Sunday buddy!

Yes you still have a monster truck trigger finger LOL with a motor like that you need to finesse the trigger.. They are like a nasty .28 with a killer top end ! you should try it in the buggy one day just for fun it would be interesting to see.....

For sure. I was able to keep up win an OS 28 in a Jammin X2, and would have passed him if I had another 20-30 feet. Just amazing power. Like I said, I'm keeping the extra headshim in, and leaving the 50 too spur on
