Yes, I knew this previously, but what puzzled me is the same plug number with Cold and Warm versions...

Dennis
I recently got a used RTO, good condition, and i was wondering would it be worth it to convert it to a turbo plug? What kind of performance gain or loss could I expect? And which turbo plug should I use with 20-30% nitro?
Thanks Roy

I am referring to, for example, a "cold" no.7 versus a "hot" no. 7.

I'm using .12 engines with conical plugs (I hesitate to call them 'Turbo') with 16% nitro. I'm starting to do some tests with different plugs, but what puzzles me is about the difference of the Cold and Warm plugs of the same number (let's say a #5 cold and a #5 warm).

For our actual temperatures (5 - 10șC air temp) I'm using a #5 warm and when temp raise will go to a #6, but my real question is: Cold or Warm? What differences are on those plugs and if are advantageous to keep Cold and Warm models of the same number (#5Cold,#5Warm,#6Cold and #6Warm)?

Dennis and others, what you think? on my 1/8 on road ever use #7Cold and #8Cold....
Corse-R, do you mean long body (cold) and short body (hot) plug versions of the same plug number?

After looking them with care I've found that ones have more 'hump' on the external side (the not threaded one). Is that the main difference of them?

To ride on this thread,

I'm thinking of getting a new engine, over here in S'pore, the a RB 5 port wld cost ard $60 bux more than the Nova 5 port.

Izzit worthwhile to get the Rb or shd I just save the $60 bux for other stuffs? Are the any difference between the 2 engines or izzit perhaps juz branding differences between the 2?

Depending the version of RB you're talking... If we talk of the 310 or 315 model vs. RS12T5 pick the Novarossi, but if we talk about the 315R go directly for the RB model.

Have one 315R and is a blast.

Corse-R, what's the reason for your choice? I thought it is a no brainer that the 315 is the one to pick over the S5. I have not heard of a 315R though...

By the fact that the 310 is pretty similar to RS12T5, but what I've 'so called' 315R is in fact the 315 and changes the sleeve and the crank (My fault). What I have is the 315 with the 5 port sleeve custom ported and the 'BiTurbo crank' of rody (the most similar to a .21 on-road crank you can fit on a .12).

If price for a 310 is 60US$ higher than a RS12T5 I'll pick the Novarrosi, but if the 60US$ higher is for the 315 I'll pick the RB blindly. Is a real spanker for the competition

I dont know the specs about these engines, but I have a question. What exactly does he do with these engines? Where can they be purchased, I've heard eBay, but I don't see them around. ...... Also, are these engines Legal?

39 pages of replies to this one thread. Maybe someone shoud suggest that the forums get a new topic..."Nitro Engines". This is just too long for a single thread.

Why? Originally this thread was to give support to Richey engines, but soon started to be a fountain of information and advice of other engines. For your information, there are threads of more than 200 pages long (Kyosho Vone R thread), others have 70, 80 or more pages? why restrict a fountain of information to 39 pages?

Don't get me wrong, but information about nitro engines are plenty if you want to do a little search, not only limited to this thread. Only you need is some need of information.

The RB in question is the 310. Here in S'pore US$1 = S$1.70, so the RB's ard 35 bux more expensive than the Nova S5. The RB's here are ard S$370. We hardly ever buy through the web coz S'pore's juz so small, most LHS are easily accessible.

I'm asking this question coz currently me and a couple of frens are running the RS12s but I got a pal here running a pretty old beat up RB 3 port X12 (still lotsa compression after 2 yrs of abuse) that came stock wif his Serpent which is putting out so much more power than ours. So all along, I thot RBS are slightly modded Novas coz they came at a premium over the Novas.
