Normally the bearing size is lazer etched on the side of the bearing race.. What is it?

The bxr just runed in, took it apart,
Useing the hudy bearing puller. As I extracting the front bearing, I can feel the front bearing is loose!!! And inserting it in to crank case, just wth my finger!!!! Same goes wth my buddy bxr. 2 bxr haveing the same issue!! Bearings are nova that rare correct size
It's the crank !case :D. Or is it bearings problem????!! Aaaa??!!!

Anybody tried nova pipe/header combos with the bxr?? Any insight into what works and what doesn't work?

Iv tryed nova manifold wth picco 2099 , 2033 , 2069 , 2034
The 2099 very similar wth 2033. Smooth 2034. Wild and punchy!! The 2069. I like smooth and got high end :nod:

Thanks. What you think about the 9901/41021 combo?

Hey guys just bought a blast v11 for my Losi 8ight T truggy. Anything I should know about it?

It's meant to be more or less made from B10 parts - i.e. a good engine. Can't tell you more than that. I'm keen to hear how it is though... I got the V9, but won't get to break it in any time soon. The first few reports here seemed pretty good(any more?) The Blasts are basically RB using up all their old high end parts...

Sounds pretty good to me haha. I grabbed two since they are limited edition. Ill let you guys know after i get them broken in

did your run your blast v11 yet ?

Hey guys i bought this engine yesterday. Has any one run theirs yet ??
Rb blast v11

I just bought the blast vll and tuned pipe combo from amain with 10% off discount code ! thinking it will be perfect for my new 8ight 3.0 kit without ripping my wallet apart! and imput on this mill i see they are selling quick from the posts above mine

Does anyone know what parts RB has put in their Blast V12?

There's a V12? Link?

Been looking at the v11, never knew much about it, so i started comparing parts numbers to older rb engines..looks very similar to the old c6 series...same crankshaft, bearings, carb, sleeve is 5+2 bypass just like the c6, bore is 16.22 and stroke 16.80 just like the c6, crank is 14mm biturbo just like the c6. Im comparing it to the c6 cause that has got to be my favorite buggy engine of all time. Tons and tons of power down low, gets to top rpm fast, and is plenty fast for the straights. Seeing as the c6 hasbt been made for quite some time and i need a new engine, the v11 seems like a great deal.

Blast V11 is about to be my race engine. I have zero exp with RB though...

Prolly start breaking it in this weekend... Expecting good things.

Blastv11 same as nova Beat 5 ? looks identical specs witch i like ...long stroke 5 ports are awesome

The Beat 5 is identical to a P5XLT I thought..

If the V11 is really all that, I might try harder to sell my V9(new and unused) to get one.. From what I understand, the V9 is more of a tame-ish buggy engine - supposedly with C5 internals..

Bearing
 

I have an old RB 5 port. Although the front bearing has finally worn out the compression is still good, so I'm debating whether it's cost effective to replace the bearing. Who makes good bearings? Information on bearing pullers? Thanks everyone

TKO Makes a good bearing that will fit. The bearing puller I like is the ofna one.

Anyone know what pitch of screw rb uses for their head bolts. I got an engine second hand and it was missing a screw. Rather replace all with new bolts. I picked up a 6/32 and it was coarse thread. Does it take a 6/32 fine thread.

And good things I'm getting. I running about 210 max so far, and this thing is good. Haven't really pinned it so I can't comment on top end, but it's got plenty of smooth bottom. Looking forward to a race tune.

This is in my 2.0 EU, BTW.

Looks like I'll be racing an old classic this season, picked up a brand new s7 l2g for cheap. Always loved this engine, too bad they dont make it anymore. Anybody still race an s7?

Most engines use 3.5mm for the head.

Here is what Amains has for head bolts for S7 and many of the RB .21 .RB Products Cooling Head Screws (4)
[RBD01060 This is the part number.

hi!!
 

i got the r.b b.9 with the r.b 2045 pipe in my mbx6tr truggy runs great love r.b engines!!!:nod:

Had my first race day with my Blast v11 and wow! This thing kills it!! My first RB and not my last that's for sure

Kills it how? Can you be more specific about what you like about it?


(Damn!! Should have waited for the V11 instead of getting the V9...... :( )

Someone with a BXR?
I would like to know more about it, how can it be compared with an O.S Speed Spec II?
I know that the best is to use the recomended plugs but can it run, idle fine with an O.S P3 plug?

Thanks

Hey guys.. I have a RB B10 I bought a couple of years ago. The engine gave me 13 gallons and still had compression. I sent it to get resized and the PSC got lost in the mail. Well... after a Nova 21-4, Odonnell POS, Dynamite V2, and a Gotech GT5, I decided to get a new psc for the B10. Nothing compares to good reliability for me. I lost the 2045 pipe and manifold though and I'm wondering if a dynamite 053 tuned pipe will work well with an RB B10? I don't really want to buy another 2045...

I have always used the NO6 plugs with mine, nice wide tuning window.

As far as runtime, over 10mins is easily achievable, have seen as high as 12-13, but this is driving with a more careful throttle finger. Bearing mind this is UK/European Tracks.

I have not run a xzb spec 2, but have run a bullitt 216 and vzb speed. Compared to the 216, the BXR had a much stronger but more linear bottom end, found the 216 to have very little bottom, then all of a sudden, bham, power.

We run the BXR's and a good friend of ours runs the OS Speeds. There would be very little difference in the top end maybe a slight advantage to the RB and the OS would have a slight edge down low.

The OS P3 will run in just about anything and would certianly work on the BXR. But as already mentioned we have had the best results with RB 6 plug and on really hot days over 30 degrees we use the RB 7 plug but the tuning window narrows up on the No7 plug

BTW we can't get any where near a 10min run time in a buggy... about 8 to 8.30 is it for us

Cheers

Mark

Thank you both, now i run a LRP zz.21c so thats why i ask to compare the BXR with the Speed.
We always run around 22-27Cº so i guess the RB#5 plug would also work fine, does someone uses the #5B?

Also what about using the BXR with a werks 2058 pipe?

No real need for the No5 plug, No6 copes fine in the conditions you mentioned.

Currently running the 2097 pipe which gives better economy and strangely, more power and better bottom end than the 2045. AFAIK, the 2097 is very similar to the Novarossi 9901.

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
