RB Concept Engine Thread..

[r1harper]

when i first started the s3 was my first engine, i would kill v specs,and rb c5's on a small track. it was all infield, and one straight. they would catch up at the end of the straight, but back in the infield i would pull away again.

Hey guys i was wondering if anyone is having problems with there l2g motors. I seen a few at my local track towards the end of the year and all of them had bearing issues.

Say it's not true
I have read a little about older generations having some bearing trouble and how the L2G should be better or fixed. Now I'm worried a little.
Is this just that they wore out sooner than they should and they will be forced to replace them for next season with something better? Get some details if you can

I would say that if you have to replace your bearings at the end of the year, I would say that is ok. Bearings are cheap, motors on the other hand are not. They are a wear item anyway......just thinking

The s3 was like brand new had about 2 races on it

What are these bearing issues? Too much play and need to be replaced already? The front one leaks so they think it's bad? What's wrong exactly if you know?

I had just about every .21 and .28 Rb they have made over the last couple of years and I have had very good luck. Very reliable. This year I am running C6 with 2045 and why I did not run this combo all along I have no idea. I replace the bearings after 2 gallons on all of them it is fairly cheap. Just my 2 cents.

im planning on putting a rb tm928 w/ the hpi roto-start in my lst2. and i have a question about what pipe to get. theres a really nice combo deal for an rb tm928 at rcplanet.com but im not sure if i should go w/ the recomended pipe that comes w/ the engine or go w/ somthing like one of the ofna jp line pipes. i really like the jp-3. and i guess im going to have to buy a stock lst2 manifold cause i cant find any rb's that will fit the lst2. i was told i could use one of the rb on-road headers and it would fit, but that just sounds to jerry-rigged. will i be sacraficing any power w/ the stock lst2 manifold? i was also told i could take the header that comes w/ the combo and go to like a welding shop and have them bend it to fit the lst2. but i just dont know about that. anyway, what pipe do any of you rb experienced guys think would be best for my lst2. cause i really like the tm928, gotta have one. thanx in advance, clay unruh

I just recently acquired a WS7II and have no idea what plug to use in it, what do ya'll recommend?

You can run a RB #6 , MC59..... It depends on high of the nitro you run too. I run Bryons 25% with a MC59 in my modded S7.

Good combo. If you ever go up to 30% you may need to use the RB #6 or even a 7 but mc59's rock with 25%

[aaron joy]

A little cheaper and easier to find too.

[bjr48]

Pick MC59s for 25% on a S3 or S5 too?????

[blktransam]

in my non turbo rb's I have always liked the rb#6, in my c6bb and my ws7x3 lg2 I have found that I like the o.s P4...I run on 30% sidewinder

[aaron joy]

Yup! I run them in my .12 RB also. I have no luck with the RB#6. But that is the plug that comes in their engines. I do run the RB#6 turbo plug in my C6 BBT tho with no problems.
