I have a rb fire 12 in my mugen buggy. It's way way way too much power pretty much skate the car the whole way round the track. Very on/off delivery. Would this be any good in the rc8tce or same thing-too much. Thinking with the extra grip and weight it should tone the fire down a bit.
It's only just nearly broken in still creeping up on race tune. If it's gonna be too much I'd prefer to not install it at all and sell it off whilst it's still fresh. Is the a way to tone it down a bit without running it blubbering rich at all?
Truggy is in the mail will be here tomorrow, currently has a works b7 pro installed. How do these 2 engines compare? Trying to work on the slow is fast principle and the fire doesn't condone this style at least not in a buggy.

I really liked the Fire in my truggy. Mine was CRE modded and it was really nice with 2058 pipe. Sadly a part of the wrist pin clip broke off and scored the p/s.

Are they the same engine?
Why is it more expensive without the pipe?

Interesting observation on tearing down the Blast V12. The crank rotor is full round instead of the usual more triangle shape toward the crank pin. Hmm.

The bottom end is unreal! Just so much power and it idles like a champ and is pretty easy to tune

Sounds good... I've tried to sell my V9 a few times, with no luck.., so I guess I'll be stuck with it. See how it goes.. Just have to find the time - and for one of my other engines to die.. I have more engines than I have time to run them these days unfortunately.. And the weather has been awful too(even by German standards..)

We are happy to release the Murnan Modified RBM5 .21 Offroad Engine.

sprattz

the rb fire is powerful but not too much for buggy
you just need to work on your setup try carbon clutch shoes
and ligter centre diff oil my setup is 3carbon rmv shoes 1st shoe drill 1x2.5mm
hole 2nd shoe 2 holes and 3rd shoe 3 holes useing mugen 1.1mm springs
hope this helps.

If you use the 053 pipe, it may give you too much bottom, if you get a Losi pipe, the 'RE12, it's a copy of the nova 9901/41021, or go with the nova rossi 2096 pipe, it's the same as the RB 2045, with the nova 41021, will work great on the B10 .

I was looking at the v12. How do these motors run? The price is very good. I would like to try a rb engine every one that has one sure like them.

Looking for some help please. Ordered a few of the RB limited edition 5 ports (Blast V12) for stock and would like to know best pipe choices and headers for buggy and Truggy please as well as best glow plug choice? Thank you.

I like the 2058 on those......

If it is the same as the C5/C6 of yesteryear and I think they are. The 9886 was incredible on that engine. Probably the fastest and smoothest engine I have ever ran.

O yea I got me one of these in the mail and I can't wait to run it!

So saw a Blast V13 on a news site. Whats the difference between that and the V12? The internals look the same in the pictures.
