what pipe would you run on a w7 worlds ? thank you !

RB 2045/192 header

thank you !!

Anytime.

That is not an easy engine to find!!! If you do find one make sure you grab it up, they were a limited production from about 3 years ago so it could be tough.

Neal at Clockwork can take a C6/B9/B10 crank and time it the same or better than the C6 USA crank was, and install a tungsten slug. Reno at RB USA got me a new Rody button from France. There's pretty much the C6 USA. Great engine, i love mine.

The original C6USA also comes with the coating on the crank pin to make it wear longer as well. Last year I picked up 1164-14/R which is the Rody tuned crank for the C5 onroad engine, and it's timing is even more aggressive than the USA crank. It was a very fast engine but the tuning gap got quite small with a crank that aggressive.

Howdy Chris. Didn't mention the coating cuz it's not DLC. Mines worn off but pin is .198" everywhere. Thanks for posting that Rody crank p/n. I would like to know actual timing #'s on it before i bought one. I'm sure they're salty. Let me know if you want to part with yours, lol.

Heylo again

Where do the Shark 9/10 fit into the line up. I can see the buggy 10 and buggy 11 being C6 replacements but what about the Shark 9 or shark 10 Guarda editions...

I know they are EXPENSIVE LE editions of some engine just cannot figure out what one :)

Can anybody tell me if the conrod of a novarossi Plus 4 will fit a RB C6?

Thanks

The Shark9 is basically a C6 with 3 ports rather than 5 and it has a balanced crankshaft in it. I really like the smooth power of the Shark9.

The Shark10 is much like the B11 except the Shark10 uses the crankshaft from the C6 engines which is a little more aggressive than the B11 crank. The Shark10 shares the same piston and sleeve with the B11.

I really do not think so, I don't think the crank pin on a NOVA is the same as RB's. I have a buddies +4 at home he wants me to break in for him so I will look after work.

It will not work. RB has .198" crankpin, nova has .196".

So the shark10 is a 5 port now, wish I knew that
If it has the old crank am I right to say it is a high torque version of the B11

Correct, the Shark10 should make a little more power than the B11.

I'm un decided now. My shark9 went on the weekend. Should I get a x10 or a shark9 p/s/r for it.
Or I have a c6 p/s/r will they work in it, if so what should I expect from it?

I want to put it in a buggy

I personally really like how the Shark9 performs in a buggy so I would try to get the P/S/R for the your Shark9 as long as the crank is in good condition. Putting the C6 P/S/R in your shark will probably give you a little more power, but also more fuel consumption, but it should still be smoother than a C6.

so to rebuild the shark9 i have to get the x10/11 p/s/r
i cant find anyone with shark9 parts

Correct, the X10 and X11 use the same P/S/R that the Shark9 used so that will be the stock replacement parts.

If I was to put the c6 p/s/r in with the shark crank, would it get more run time than a stock c6?
I know it will proberly get less run time than a x10

It will probably be very similar honestly, the only real difference is the Shark9 has the balanced version of the C6 crank. It may be a little smoother but may very likely rev a bit higher.

What I do when I want a bit extra fuel mileage and power is drop in a ceramic bearing.

if the new B11 has been designed to increase runtime over the B10 does it still have as much power? it seems that RB dont really have a motor suitable for truggy anymore.
I know i could mod the B11 for more power but wouldnt it have made more sence if they kept the C6 line as a high torque version and the B11 as a runtime version.
its a real shame that they have killed off the line. alot of people run the C6/B9/B10 line of motors and now its going to become a motor thats hard to get parts for

Hi Tix

Actually, the B11 is really powerfull, even if we reduced slightly the timings to make it less aggressive and more progressive. However, if you think you will not have enough, go for the FIRE 11! This engine is a monster of power, 7 ports sleeve and really aggressive on-road crank, perfect for the truggy! I will use this one on my truck.

What pipe and header combo do you use in your durango?
thank you.

Will this piston and sleeve fit the ws7 iii. PN 01133-S7.

Yep, that's the part number for the WS7 lll piston and sleeve.

Thanks.

I was told last week there is a front and rear orientation for the head button. At least on a Nova 4plusC. Can some one verify this for RB's and if so what the proper orientation is for a WS7 turbo button.:confused:

Nope, not on RB WS7, or any of the RB engines, the LG Heads they have will go either way,but there is a notch on one end that gives more room for the header.

If the button has any markings on it they usually go to the exhaust side.

This is an RB, not a Nova, havnt heard of such on any Nova based engine, it doesn't make any sense, the factory is not doing anything to the head button that would make it be directional.

All the head buttons are round, the cylinder is round, the sleeve is round, the head button combustion chamber is round, no matter how you install it, its still the same.

Agreed. Most man'f and engine builders recommend keeping the button indexed the same way after removing it. Somebody else can chime in as to the reasoning for this. My RB has a button that must be installed 1 way only.

How do you know that its installed only one way? What will happened if it is not installed that one way?

The Rody button on a C6 USA has a cutout in the squish band that must face the exhaust.

Is that the only head button that has an identification mark or spot? It still should not make a difference, when you install another glow plug, will it make any difference on how tight you make it? maybe 1/32 of an inch before it bottoms, from the previous glow plug? And if the heads shims have rotated, that could make a difference also? I would like to see some photos of that.

It doesn't really matter as a sleeve is supposed to be a perfect circle but 9 out of 10 times the sleeves are a little or of round,i am pretty sure that's why novarossi wants you to install the head button/combustion chamber the same orientation when assembling ;)

Thanks Monty, now that makes more sense, but, I doubt the out of roundness, will make any noticable difference that anyone could tell, unless you put it on dyno or a machine that can give you rpm and horsepower range.

Ya,i am sure it really isn't a huge deal but it wouldn't hurt if you put it on the same way every time either would it? ;)

I get this call pretty often," which way does the button go?" , its a circle, does it matter?

Lol, I can imagine, simple, round head button, round sleeve, now, MATE!
