Picked up a Matt Russell moded B11/2087.I have put about 1.5 lrs through it and started to lean on it a bit today. Running in a RC8T this thing is awsome. Plenty everywhere but more torque than agressive, 9.30 min still running an hour or 2 on the rich side compaired to 8.00-8.30 with an Alpha A852/0801. Motor does not have the bottom end of the alpha but it gets the power down a lot easier. Was unsure how it was going to go in a truggy but am very impressed with how it goes.

Anyone ever run the odonnell r2 pipe on a rb engine. Either c6 or the shark9?

Anyone?

I have never ran any of the odonnell pipes. If you already have the pipe your best bet is to try it, it's not going to hurt the engine. Heck you may find that you really like the power band!!!

Thanks. Ill give it a try. Just dint want to ruin the engine.

I have a 2058 pipe, I forgot that I bought one on amain when they were selling Nvision parts on sale,I took a pic of the 2 side by side, you can see the difference. Oh, and I picked up a fire 11 on eBay, had 2 tanks of fuel thru it, 150, I want to try it out. What size restrictor did you run?

In Phoenix on a hot day you should run the 8 just to help get some extra air in there. If your gona run at night the 7 should be great. I personally never like to go smaller than 7 or small weather changes really seem to change my tune, but that may not be as bad for you at a lower altitude. You should try to get out one day and try all those pipes on the Fire11, I know it's a rocket with the 2058. The 2045 will be a little more mellow and easier to drive in a buggy, and the TP pipe will do the same. I have no idea about that 2057 but would be curious how you felt it runs on your gigantic track :)

I
Mostly race truggy, so it should be fun, how is the fuel mileage for that engine? About the same as a C6? We usually race at night time out here, its to hot in the day time. We used to run the 8 plug only way back when.

The fuel mileage will be a little less than a C6 if you drive really hard. The F11 makes more power IMO so if you can make yourself drive it easy and not use full throttle all the time you can actually get better mileage as you will be able to clear jumps and run the same lap times with less throttle input. Or you can take full advantage of all the power and smile a lot :D

LOL, thanks, is the 2045 the best for economy as well?

I do always get the best mileage with the 2045 and 192 header. Also if you have a carb from an old WS7 you used to run or an older C6 you may want to put that on the F11. The carb it has will work fine I just do not like having the idle screw on the front of the carb like the F11 came with.

Yes, I know the your talking about, I have picked up some new Nova carbs on eBay, peeps parting out new engines, its the newer style, with the idle screw, on top.

Anybody knows the factory needle setting for F11?

HSN 3.5. LSN 5

How is the new Fire compared to the Fire 11? Even if just on paper, should one expect more power from the newer version? The main thing stat-wise is just that the new version is a 7+2, the Fire 11 a 7+1...

New Fire:


Competition racing engine
7 ports + 2 by pass
Lightened conrod
Turbo plug
Turbo combustion chamber
14mm bi-turbo crankshaft (long stroke)
14mm rear bearing
9mm nylon carburetor with 9mm venturi included
L2G cooling head
Strengthened crankcase “black coated”
Aluminum orange anodized wrist pin
Dust protection caps

Looks like the kit version here even comes with the bearing cover for behind the flywheel...

nothing has changed but the lettering on the head ..... both engines use the same 7+2 sleeve

Well, according to RMV, it's more than that..

http://www.rmv-deutschland.de/motore...oad-xtrem.html

"Er war die absolute Überraschung der letzten Rennsaison und hatte vielerorts für Aufsehen gesorgt. Nun die neuste Generation des OffRoad-Triebwerkes von RB Products wurde an vielen Punkten überarbeitet und überzeugt auf der ganzen Linie durch eine überragende Höchstleistung, unbändige Drehfreude und ein einfaches Handling, was zu einer deutlich höheren Nachfrage und Beliebtheit dieses Motors führen wird. Als Dankeschön für das Vertrauen unserer Kunden kann RMV Deutschland nun auch dieses modifizierte Ausnahmetriebwerke leider für einen begrenzten Zeitraum zu einem deutlich nach unten korrigierten Vorzugspreis anbieten. Jetzt oder lautet damit die Devise, denn nie war es einfacher sich die Power of Champions in ihrem Rennbuggy zu holen und der Konkurrenz einfach auf und davon zu fahren."

Roughly translated, the new version "was revised on many points/in many ways"...

The carb is new too I guess. The "XTREM" version from the BXR I assume..

Well then ask RMV for the timing differences between the sleeves......see if he can tell you the differences in the port timings .......... My bet is there is no changes in the sleeve sets........ same timings, same layout, same ports.........

Got a mail back from RMV. They (Daniel Reckward, apparently) basically say the sleeve has been modified by installing the multi-exhaust system, resulting in enhanced power, and the cooling head has beel slightly modified. (rough translation from German)

Edit - not Daniel Reckward, but Matthias Reckward.

the F11 also had the MES exhaust.....as I say nothing has changed.....

edit... with RB who knows, they have multiple sleeves they use in these fire series engines.....I have cycled thru a couple dozen of the F11 engines and every one of them has had a MES exhaust....however the first couple engines had a different style MES sleeve...but only a couple, the rest have the same sleeve they show on this latest version............

here is the two styles of Fire 11's I mentioned

Neal, in your opinion, what is the difference with the 2 sleeves, as far as performance? Fuel mileage?

the timings were identical, so the differences would likely not be noticeable......the dyno may pick up a slight difference, but on the track we they would feel like the same engine.....Of course this is referring to the two sleeves I posted......Some of the older F11's had a single exhaust port, which could have had a more noticeable difference depending on the timings used....

Thanks

Have you ever fired up and ran the F11 that you bought seven or
eight months ago ? Or are you still looking for someone to tell you
what pipe will work the best for your set-up on that engine. Have
you saved up enough money to buy the right glowplug to run in it
yet ? Let's hear some feedback and or see some video of your F11
rippin it up. :nod: .........:tire:......:tire:...

Get a life.

anyone can recommend a shop that ships internationally for the E01012-BXRIL engine+pipe combo ?

thanks

Where are you located?

Hey guys, I was wondering was an optional pull start available for the X12? and where can I find it? I tried searching but didn't fun much! Thanks

FYI : @main has the BXR and BX in stock for much cheaper than any other US location.

Combo :
BXR w/ 2097 pipe : 449.99
BX w/ 2097 pipe : 389.99

Just Engine
BXR : 389.99
BX : 319.99

These are about 80-110 dollars cheaper for any item you buy compared to other places. Combine with the 25 dollars off 250 for an even better deal.

I bought a BX w/ 2097 pipe because I didn't want the BXR since people are comparing it to a C6 USA engine which is to much for my buggy.

Can someone who has ran both give a comparison between the BXR and the Nova Plus 4 BTT......power, runtime, realibility/tunability?

Thanks!

Since they are both made my Nova Rossi. They both are well built. I would suspect the BXR has more power every where. The BXR is suppose to be similar to a C6. Everything else should be comparable. Both are very good engines.

Hi.
Well... Allmost every RB driver in Denmark struggles with flame-outs this year. The power is fine. I don't know about the powerband and runtime on the RB engines but I would guess they are as great as Novarossi engines. I was pitman and tuner for a BX engine at the Danish Nats. The engine sounded really great in the semi, but never the less it flamed after the second pitstop. I must say it was REALLY warm that day and many other engine brands had flames as well. My experience is that its not the engine itself that flames, but the tuning and especially the glowplug, that is the reason for flames. I can't stop wondering why RB has made two new types of glowplugs this year...

I assume that was without the Plug #5 V3 "special" that was just released. I know Reno Savoya had flame issues during the Nitro Dirt Challenge in the USA which is like ~Feb 2012 this year but in the Euro Finals this month there were many RB engines in the final. Reno got 4th. I assume he was running the new plug and there are no more issues.

He ran the V3 plugs RB released in February this year. The brand new plugs http://www.neobuggy.net/modules/news...ds=rb+glowplug is still not available.

Just ordered a few.

Cool. Otherwise Novarossi C6TGC and C5TGC are absolute perfect for RB engines - or any non-OS-based engine :nod:

What is different to these compaired to the RB#5 V3 glow plug (Hot) that Amain has listed?
