Ive had our local driver try all of the new range BXR engines in STD form and we run and I supply the SLS3 without ceramic as RB supply the engine or I install before shipping as an option. The SLS5 and di5 didn't give an improved runtime and the low end was not as good as the SLS 3.All engines were run and tested using 2097 pipe with med header.Hope this helps LS5 gives very good results as well .

Hi,

just bought two used BXR (1 gallon) from team RB with a friend. One is a SLS3 and the other a SLS DI5

What would be the differences on a track?

thanks!

Fire 11
 

Hi, I have a fire 11 but it was damaged when putting in new rod so now I need to put a new piston and sleeve (the rest is ok). I can't seem to find a matching piston/sleeve combo. Does anyone know where I can get one and also if I can't find the exact match, what else could I use?

Thanks.

The obvious thing is to say try both but run them on the 2097 with med header not the long one as supplied in the combo's.

We run the SLS3 with probably med distance tracks (40-45 sec) and milage is critical and the 3 gives better milage and more low down punch.Only thing is the 3 runs without ceramic as STD.

It will be good to hear which you prefer.

RB Rocket to replace the Blast line...

http://www.redrc.net/2014/09/rb-rock...ne/#more-86084

So is that basically a Blast V20/Rally, or closer to a BXR?

What's the difference between med and long header?

are you talking about the compact v2 version?
http://www.amain.com/RB-Products-50m...d-Short/p24608

I will try both of them I think :)

Coming from e-buggy (racing for 4 years now) I was surprised to achieve the best laptimes with the most powerful engines in nitro.. It's weird for me considering iI always looked for very gentle motor response in electric. Maybe the progressivity of the clutch is part of the explanation.. and the MP9 too, which is very easy to drive even with a strong engine (I used to drive more nervous cars before)

Is there any difference in performance between an used and new pipe? And is there actually a way to clean a pipe?

Noob questions I know but I just began nitro a few months ago.

edit: a french RB driver is suggesting the 198P manifold with the 2097 pipe (SLS Di5 engine), did anyone here try it?

standard:

198P

up,

need some advice to choose the best manifold with a SLS Di5 + 2097 pipe :)

I'll be racing on medium tracks mainly

I would use the RB ParaVSM on the 2097 ....or even a Novarossi 41001..........Those 17.6mm stroke Nova's/RB's like the short manifolds...

Thanks Neal, I'll look at them :)

Any thoughts or experience on a WS7 2 with the THG02 Truggy pipe? Thinking of trying this. Currently running the Losi sport pipe(8ight 2.0 rtr pipe) which has been absolutely beastly strong. Also any thoughts on turbo head button? Worth it or not?

venturi for rb bx (old)
 

hi,

I've bought this engine for my buggy, a new one:

http://www.ebayhpirccar.com/images/img/rbd01012-bx.jpg

the original venturi is 7mm. Which venturi do you mount? 6, 6.5, 7?

I need at lest 8 min mileage.

Leave the 7mm in until at least 6 litres or a 1 1/2 gallon of fuel has been through the motor and see what run time is like then, should easily get 8 min with the 7mm in but will only do this when the engine is fully broken in all metal pinch is gone.

My friend just grabbed a RB S5 L2G engine, can anyone give me feedback on it? Couldn't really find alot of info. And also does anyone know of a turbo head button that will fit ?

Keep the 7mm in and through the 6mm away .You'll get 9min to a tank with that motor .Ive even seen 10min to a tank.If you want to buy another one then the new designation is BXR LS5.

It's a mild 5 port engine, good for small tracks/indoor clay tracks.Its a RB/Nova engine so its good.The turbo button for it http://www.amain.com/RB-Products-Head-Button/p4828

Thank you!! So far break in has been easier than I thought idled through four tanks without a hitch

What's the deal with the 2045 pipe? I had the chance to sell the 2041 Turbo I had on my modded Beat B5, which IMO was soft on bottom but good on top, so just threw on an old 2045 I had laying around in its place. I was hoping to test today, but as usual this year, I didn't get around to testing it.. Anyway, is the 2045 good for power?

(I got the 2045 in a used engine deal, and it's been laying in a drawer ever since. I've never run a 2045....)

The 9901 works best on the 5 ports, 2045 maybe okay, 2 what header on the 2045 do u have?

Excited to be selling and modifying the Rb engines! Rb is making a big comeback in the Usa. Awesome looking engines.

Very keen to hear about the Rocket.....

As for RB in general, it's a shame the Blasts are done. I personally have no interest in $300+ SLS5R+cubed engines etc.. So I'm still interested as long as they continue to offer the budget engines... Which unfortunately seem to come in ever more limited numbers...

I've got a new V15 sitting around here I might send out to be modded at some point....

Holy crap, had the chance to try this combo out. Combined with the an exhaust cooler, I was easily getting over 10 mins of runtime. More power than I needed anywhere on the track. Triple was no challenge even without much of a run up to it. Thoroughly pleased with this setup as I can keep pace with brushless buggies through most of the track.

The turbo head button with a turbo plug will gain more power also.

Hi guys,
Can't make up my mind between a blast v20 or v21? I had a P5 XLT and enjoyed the power on that one. What I did not like was replaceing the bearings after 2 galons.
I run this in a serpent buggy.

It's weird, there are pretty much no threads or reviews about these engines?
Also how do these V20 and v21 (stock not clocked) react to the Nitro-Mizer insert? and how do they compare in performance with a p5?

Thanks

How about a video of the Rocket?..... :tire:

I had the v20, great motor, actually ran it in my Truggy. Plenty of power, it was a clocked engine. Also have had about 6 P5's and never had to replace a rear bearing? I had to replace a rear bearing in the V20 though but I dont blame the brand, they are all Novarossi engines.. Both are good engines and for the price can't be beat. Can't go wrong with either.

Which one of the newer rb engines is related to the c6 of old

the V12 iirc

what is the part # for the v12 iirc

I think more than the V12 were C6 based.. V8, V12, V14, V15, and more....

All Engines have this problem after some gallons. Is air getting inside. Check all o-rings (all on carb and underhead and back plate). Sometimes is also front bearing problem. Sometimes both. If you intending to fix this, just for the experience for you to gain more, try one step at a time so you know what was the problem.

I have realize that when flame outs take place after refueling, most probably will be carb o-rings. But i couldn't really find exactly the problem so i check all o-rings and front bearing every time. rear bearing doesn't really cause problem tuning but it cause a lot of noise when engine is running. Main problem in my country is having this small parts and repairing the engine.

Any experience on troubleshooting the Engine? Specially BXR? Please experienced guys share some knowledge.

Anybody still running a Blast? I still have a NIB V15 that I can't sell, so am wondering what to do with it. I've had two engines modded by the same guy so far, and honestly I've seen nothing over stock. I'm not going to send it overseas though to get it modded in the States... I suppose I could send it to him again and really emphasize that what I want is more power. But I don't want to spend €100 needlessly... Or maybe the V15 stock is just fine for beating around(in a truggy, buggy, or SC8.. Not sure yet..)? On a 2058 or 2013 (I'd have to spend €50 to get the latter...) I wish it had the blue front bearing...

If it didn't get done right the 1st time it won't the 2nd. Don't waste ur money. Very few engine guys do timing changes. That's why only 1 guy does my engines.

Hambone is right, if they are not making timing changes it isnt helping much. There are only a couple modifiers in the Usa changing timing and understand it. I was just working on a modified engine this week that had only 185 degrees of total crank timing. I did one other just like it for the customer and all I changed was crank timing and he could not believe it. He also was getting over 2 minutes better runtime!

I might actually be able to send it over with a friend or relative and just have to accept getting it back over a longer time period.. But if I spend to get it modded for power, my next question is, if it gets a big increase in power, does that mean a big decrease in longevity? It's kind of hard to believe it wouldn't.... How's the stock timing on a V15? It's already got the double filled crank, MES, etc..

Hi fellas, I recently ran my Blast v20, Dash for cash Barmah Victoria Australia, my engine is clocked, bye one man ONLY. Engine ran flawless ALL weekend, with Saturday qualifying day in the 40 degrees. Never ran over 110 degrees. The bottom end power on this engine is unreal, it had so much power on any part of the track. What was more surprising is the run time this engine has, easy 14min tank in my truggy. I also have owned P5's, they are a awesome engine, never had bearing problems, now run clocked Clio, this compared to my stock Clio's is like chalk and cheese. Im a big believer that a stock engine will NEVER perform the same as a Clocked engine, or last as long! Get the right modifier and your world changes for the better!!

Well. I'm happy to say they I've pretty much finished the break in on my Kanai edition RB.

It has been a dream. No flame outs and idles until the sun goes down.

I picked it up when Amain had them on sale. I started running nitro as a second class to 1/8 electric mid last summer. I had a couple old GoTec engines I used for the remainder of that season.

This RB has been great. Im actually looking forward to running nitro instead of dreading it.

I am interested in the RB Engine. Is there a break down of what is current for a Buggy. I have been using Novarossi for a while. So OS.

I use the BXR SLS5DI5 in mine. Incredible engine. I have also used a BXR LS5 in it too. It works great and is a good bit cheaper.
