Just wonering what the difference is between following engines

12-3c
12-3ct
12-3sct

Bit confused guessing t is for tuned?

the C is for Ceramic Bearing

and im not sure and dont quote me on this but i think the

S is for Silicon filling in the crank

and T is for some work on the liner.

a Tuned version has work done to the crank.

The Plus 12-3c is the engine with ceramic rear bearing and standard plug
The Plus 12-3ct has the ceramic bearing and uses a turbo plug
The Plus 12-3sct has the ceramic bearing, turbo plug and uses an 11.9mm crankshaft (the c and ct version use and 11.5mm crankshaft)

I am going to revise what I said as it appears I am wrong. I downloaded the exploded views of both the 12-3C and the 12-3CT and there are two differences. The cylinder heads are different (almost positive the only difference is what is written on them). The other difference is the crankshaft. EVERY other part number is identical. The SCT has a larger crankshaft 11.9mm vs 11.5mm

I knew I had answered this question before, . Just didnt remember, i made a search back on the thread and found this:


The "S" is there to distinguish between the 11.9mm and the 11.5 mm crank
The "C" is there to distinguish between Steel Rear Bearing and Ceramic Rear Bearing

The "T" is there to distinguish how worked up the crankshaft is. See these pictures:

"T"


"Non T"


Hope this helps. This is what I know, someone please correct me if im wrong.

Ok thanks guys...

Another question


12-3 series motor vs a 353 series

Pro/Cons differences?

Thanks

Nitro-Racer*

well the most obvious difference is that the 12-3s have low to mid power, while the 353 has mid to top power delivery. there is also a difference in the conrod and crank pin. my suggestion is to get a 353 unless the track that you are racing has little straights

they are basically the same engine, 353 has 500 more rpm, but a 3sct can be as fast or even faster that a 353, get what u like, what u can get the parts for real quick, look at what will last longer, dunno about the new 353 but the old 1 use to wear a bit on the crank pin

I believe the new 353 09 has an extra layer of coating on the crankshaft. Supposed to be lasting longer. You can see the discussion on the NovaRossi 2009 thread

yea and i think they have gone to the same rod as a sct now
