I noticed that too. The case looks Sirio but the carb doesn't. But then they have that NR clone orange carb on the Sirio based Xenons so my guess would be Sirio.

Dremelboy I hope you can answer this one!

What is the differece between the .12 Matrix R and Matrix RW I just got the RW version 010112-001000 I looked on the site but they look the same to me.

Ok this question is for anyone with an opinion!
I have a brand new RB Concept V12 5 port RODY engine. I'm not sure if I want to use it! I heard they are very hard to find! besides its not race legal, should I keep it as a colection item so I can show it to my grandkids lol OR just I just go ahead and brake it in and see what it can do?

Any sugestion is welcome! Thanks in advance!!!

There good engines but not a collectors item. Run it or sell it. It's just an outdated fast engine.

Hi everyone.

I have an Inferno MP7.5 which is only used as a BMX track basher. The current Nova .21 motors life span is up. Im looking to fit either the RT9 or WS7.

Which motor out of the two would be more powerful?

Secondly I need clarification. The RT9 on the official site gives item #01909-000222.
Ive seen some RB truggy engines with item #RBC01900-000222.
What are the differences with these two motors?

Any advice would be appreciated.
Thanks

Yeah your right I will start braking it in and see what it can do, that's what it's for right?

Is anyone running a stock RB T9 or T9 RC? I'm looking for comparison in performance to a Novarossi 353 and or a Nova Plus .12 sct.

Got my new RB T9 and so far have put 6 tanks through it for break-in. Will be racing this weekend at our local short track with the Novarossi 2630 pipe. Any suggestions on other pipes which will work on this engine for large tracks?

The 2601 will work with better fuel mileage than the 2630 but not quite the performance.

Hi everyone, I want to know too, beside RB2604 Pipe , any other suggestions?

thx alot

Alright time for the new power plant for the 733, running it on a short track, some tight turns, like all of us, of course I want the biggest baddest .12 out there I was leaning towards the T 9 on road competition, what do you guys think, good to go, or to much for a tight track. Any other suggestions.

Bump..............Any opinions?

Short tracks the RB2604 is the best , bigger tracks Nova 2652 or 2630 , The Rb2604 does work really well with the T9 on most tracks

does the T9 RC have ceramic bearings

if you can choose between RB T9 and 353 09, which would you choose and why?

If you get the murnan version it comes with ceramic front bearing , Standard no ceramics
