Looks like it's a three port sleeve, huh?

Did you have a hard time getting the rod out? I couldn't get it out which I why I didn't have any internal pics. Also, note the cut on the exhaust port on the case. Pretty trick.

keithw11 02-13-2011 08:43 AM

yes just like os v spec/speeds

keithw11 02-13-2011 08:51 AM

yes it was tight and so was crank it was snug tight tolerances and the exhaust port was matched very nice

i put a p/r/s in a speed case.. at 98 bucks for p/r/s compared to 169.00 for sleeve and piston and 47 for the rod from os.. 98 bucks looks a lot better in the pocket book... all the specs are the same as a v-spec... the case and back plate are a tade different but ALL the other pieces are the EXACT same as a v-spec..... jeremy

ps.. answer-rc has all the parts and motors in stock... talk to mike for questions

keithw11 03-01-2011 05:13 AM

well motor ran great this weekend never got above 230 all weekend ran a 2060 with it got 12+ runtime no joke i won and tqed both int buggy and truggy at the ice breaker this weeken in texas 150 total racers 35 int buggys and 20 truggys i won 625 bones:)

so i have around 1 1/2 to 2 gallons on this motor and you still cant roll bye hand this thing has just preformed flawlessly

Talked with Mike at Motorama and brought one home to play with. I should have porting and performance results for you guys soon. It is laid out very close to the V-spec as most have mentioned and it should run awesome with some race porting. The stock ones looked really good at motorama so I am very interested in seeing what I can come up with for them. I am also interested in seeing how the new hardened crank works out. If it has a nice wear to it and if the carb is decent, it should be a very nice engine for the money. I will keep you guys posted!

I have almost 2 gallons through the engine,it is great so far,zero flameouts,easy to tune,i would say it has more power than the standard Vspec and just a bit less than the speed,quality of the parts is actually great,so i would say it is a really good engine,overall...

That's a pretty sexy engine..

triplesix 03-03-2011 05:59 AM

A yery interesting engine, I have to admit.
Which pipes are you running/which are recommended?
Any words on fuel economy?
