RB Concept Engine Thread..
#3617
Today we put some more fuel through the TNS Tuned RC CONCEPT M5C/2046 combo in one of the new guys at my local track in his mugen mbx6 buggy, still on a slightly rich tune, the retun to idle of this engine is amazing and the powerband is very smooth, cant wait till its fully broken in and on a full race tune.

Summoning old timers please!
Got an old engine to revive my S5 (no, really, the square stroke RB S5). It must be some early engine from RB because I can't seem to find any picture of mention of it. Here's some clues:
-Purple head (in the style of the first S7 but with less fins);
-C5 case like my S5;
-5 port liner with divided inlet port, square stroke like the Sx engines;
-the head has the glow plug button incorporated like the S5.
I'm at a loss here, a purple head RB????
I dropped a new conrod, S5 crank and head and I like how it goes with a 2058 pipe.
Huh?! A CS Sport? Has anyone heard of it?
Paco to the rescue!

Follow up to my woes with the S5-CS engine.
The head bolts came undone and I didn't notice it, no excuse
but with the only venturi I have here, a 6.5mm, the engine has some poke. The tune is not there but shows lots of potential.
It's a square stroke I can confirm that

Is the Rally 9 engine Italian or Taiwanese made?
Secondly, if the former, is it likely to be more aggressive than a Blast V15?
(Might offer a trade..)

I see bore and stroke are the same.. Looks like the Rally has the blue front bearing too..
