Yes, it will run, but it is short, to wear it does not extend all the way into the button combustion area, basically. not as efficient as an Rb plug, or others that are longer than the short OS plug.

Classico 10
 

Has any one run this motor and how does it run? I want to put it in a dirt oval car.
Any help will be appreciated

OS Plugs (Turbo at least)
 

On my WS7 I've used a P3 plug forever. On the turbo side, if you use a p3 never use a nova plug again.

Look Billy Easton runs a p3 in his B10/B9/C6.

RB Killer 9
 

I'd say its a great engine for the price. It can hold it's own against some of the best motors out there. Its been one of the best motors I have owned and I've had WsIII and c5 and c6 motors. the low end is better than the ws3 and top end like a s7. For the price you can almost get 2 k9s for 1 b9/10.

mine pulled on a vspec pretty good in this video and I could have caught him but he would have put me into the wall if I did lol.

My K9 has almost a gallon on it now and is really starting to come alive. It runs consistantly in the 205-210 range and has really good rip. I am going to start leaning it out now and get it tuned for max power and see what it will do. I am running it in a MBX6 with the 2045 pipe and 192 header and have no complaints at all running against OS Speeds, Reedys and JLs.

Anyone tried a CROSS 10 or know any feedback on what they're like ?

Rb Engine protect
 

Part #02010-001. Should fit every Engine, Clucth. I tryed it on my losi 4 shoe and fit perfect the way they its made it well fit any motor im asuming not 100% but really cant see how. A great price too at only 16.99 give or take at you local hobby shop. I TRULY think it well make you engine bearing last longer And Your motor due too not any have mud dirt geting any were it every again. The rb Shark 9 a great motor but im really laking top end go to try a novarossi 9886 pipe with the L shape ofna header to see if i can wake it up. My temps are around 260 i know you shouldnt go by temps but all my other Rbs run around 220-250 with great power. What do you think Chris P. I feel i have a good bit of fuel thought it 2 1/2 gallon and more. Thanks for any help bro Speedyrob

The part number you need is 1143-WS7. The other part that would work is 1143-WS7M this sleeve will have the 3 port MES exhaust ports rather than just the one exhaust port.

Try the 9886 pipe and see how it works for you. My Shark9 is just starting to break in and it seems to do great on the straight. I am running the 192 header with 2045 pipe on it as well. As for temps I don't know what mine is temping at, I never even carry a temp gun because then I always end up chasing a tune. If you have good smoke I would say go ahead and lean it a little more and ignore the temp gun. Once my engines are broken in I lean them out till they perform well, produce smoke, and don't lean bog. If you really want to know the temp use the water test, it won't tell you the exact temp but if it boils off as soon as it hits it might be a little too warm.

I have 3 G's on the Shark 9 and has been a great Engine. Temps around 230 all day long.

Think you should check your settings, my shark isn`t laking top end at all:) Running stock setup with pipe.

shark 9
 

Going to try and test the nov 86 .Igave the motor one more try this past weekend with stock pipe and 8mm restrictor temps hot 270 and still no topend. I was geting past on the straight like i was sitting there at my points race. I think the 2045 to long for this motor. Once again loving the RB Engine Protector im not a sponsored driver just love products that work and on ANY setup. Track was muddy this weekend can home pulled the protector off and the bearings clean as can as new Wow. speedyrob

Engine Protector
 

I have a few RB's they are "grooved" by the front bearing (S5/S7/WS7 all the same case). It was 1mm smaller then my Ninja OS. Maybe most novarossi based engines have this groove feature but I'd be pretty certain this protector will not fit OS based engines.

Try a short header. The 1 that comes with the 2045 seems a lil long and kills top end. I put a short L shaped mugen header(JX14002) on and top end screams and temps dropped about 20 to 30 degrees. Did the same thing on c6 and my buddy couldn't even control it it had so much more power all around.

WS7 III Needle Settings
 

I have a WS7 III that I have rebuilt. The engine has been broken in using the "factory settings". I am struggling with a base line "racing tune". There seems to be a some "lag" coming out of turns. I am using a 2045/198 pipe set. 1.0 clutch spring with a stock RC8 flywheel. My gut feeling is the LSN if off. I know RB's are sensitive to LSN settings. If my memory is correct, RB's like rich LSN settings? Can some body give me a starting point for my HSN/LSN settings as well a a good base line temp? I live in Atlanta, Ga and run Byron 25%.

You don't want to tune these engines with a rich LSN, that will cause you flame outs after getting refueled. My WS7's LSN is normally between 4.5 and 4.75 turns out. That is generally close to flush or out from flush a little. The WS7 is more of a top end engine, I run a Losi buggy that comes stock with 13 48 gearing and I always changed out to 13 50 to get the bottom end I wanted, the engine still has plenty up top for long straights as well. Tune the engine so the bottom is nice and crisp and responsive. If after being on the track for 5 minutes or so you notice the low end power really falls off you can fatten up the bottom some.

Been there done that on the flame outs after fueling!!! So it appears that you run yours not far from the "factory" settings; HSN 3.5 LSN 5? There is the option to go with a larger spur gear on the RC8 buggy. Maybe I should try that as well? Never had a problem with top end! That is why I LOVE this engine! Thanks for you help!! I have added a turbo head button as well and run an O'Donnell T97 plug. I have played with the T77 as well.

Yeah my LSN is generally pretty close to the stock settings of 5, the HSN is usually around 3 turns out once tuned. I would try a larger spur gear for sure!! For me the WS7 was never a great performing engine until I geared the car to fit the engines power band. After the gearing change I had all the bottom end power I could ask for with slightly less top end. I only notice the loss in top end on tracks that have a straight longer than 180 feet.

Have a Killer10 on the way .
Will be running OD97T plug
Other than the 2045 pipe with 192 header , what other pipes have people tried with great results ?
What run times are people getting out of this motor?
Any tuning advice for this motor
and what type of life should i expect ?
Should i change the rod early on or run it till it lets go ?
Are the bearings holding up alright ?
I think that is enough questions , i've got them all covered in 1 post :lol:

is anyone running their C6USA in an 8T 2.0?
are you running stock gearing and what size venturi are you running?

im down to a 6.5 and i am thinking of going up a clutchbell size to smooth out the power a little bit

I run mine in a 2.0 truggy. I race at 6,000 feet elevation so with all the horsepower that I lose from that I run the stock gearing. If your going to change the gearing I suggest you go from a 50 tooth spur to the 48 tooth spur, 2 teeth on your spur gear is less dramatic than 1 tooth on the clutch bell. I myself run a 7.5 venturi in my USA. but have tried many sizes, I always seem to like 7-7.5 the most and still easily pit 10 minutes.

Do you know much about the cross 10 Chris ?
I'm interested in one but can't find anything on them.

Cross 10 is the same as the Shark 9. Very smooth bottom and top is good w/2045 192 pipe/header. I have owned a handful and have been extremely happy. The power is very close to a C6-B9-B10. If you want one let me know :)

thats what i was thinking
i already have too much pace at the end of the straight with this thing so a 14 is only going to make it worse
im only running at about 375 feet and the temps are around the 57 degrees Fahrenheit so im not loosing any horsepower
i got down to a 6 last weekend and hadnt changed the tune from the 6.5. so it ran a little rich and still got 10.30. if i tune it up with a 6 i think it'll be perfect

I ran one with an re10 pipe and was getting around 9-30 to 10 minute in buggy.The bearings and rod hold up very well and the pinch last a long time.Myself I didn't like the 2045 it killed the power and temps went up 30 deg and got less runtime.

So you had good luck with the RE10? Just started running my newly rebuilt C6 USA. It has a bad air leak somewhere. Won't idle at all. Thanks to Chris Peralta for the carb settings. It won't come close to idling with the carb idle gap set properly. Won't stop racing. LSN has to be very rich and the idle gap very small then it just stalls. I'm going to put my FMS carb on it. Looking forward to racing it. Motor showing killer power even with air leak. I will be trying my RE10 also.

Had good luck with the RE10 on the k9.I've never ran a c6 so I don't know what pipe to run on it but heard they have killer power.

I have not yet seen a cross10 run but I do have the Shark9 which is basically the same engine except the Shark9 has a balanced crank and the Cross10 does not have the balanced crank. My Shark is starting to run great and getting much better mileage as well, pitting at 8 minutes I only needed 80CC's to fill the tank so 10 minute stops should be no problem now that it's fully broken in.

My Shark 9 is really starting to come in nicely with 7.5- 8 minute stops running around 250 in my MBX6. The Shark makes wicked useable power and had no issues with short run-ups to big jumps and no issues with the lower speed rythem sections this past weekend at our first RCPro regional race in Alberta, Canada. I qualified and finished 3rd in expert buggy against some pretty stiff competiton.......not bad for an on-road guy:D
Look in the pic who tq ed and finished first:sneaky:

Nice...I told you that Shark was good :D

Yeah thanks Don, it took a while for it to break in and after I realised that I needed to run it a little hotter than I thought 240-260 it really makes wicked power and has decent runtime. It is also taking me a little time to get the whole clutch thing figured out.....one other thing that electric on-road does not have:smile:

Is there a turbo head button for the S9 and what plugs do these engines like the best? I run 30% OD and 2045/198 combo with a 6.5mm restrictor.

Thanks

01080 is the part number for the turbo button for an S9 engine. As for plugs I prefer the number 5 plug unless the temp is close to 100 then I will run a 6. These are RB plugs, they seem to last much longer other plugs I have tried in the RB's.

I need some new bearings in my WS9, where can i get a ceramic bearing that is 13 x 25,4 x 6 ?

Glo plug size/thread length
 

I’m sure I had read the RB S5 motors took a plug which have a longer thread than standard.
Is this correct ?

I took the one out of the motor to show the hobby shop and they said a OS A3 or A5 are the same type of plug,just need to choose what temp range is required.

As the motor was used it may have had the wrong plug installed,so I may have shown them the wrong sample plug.

The only standard OS plug that is the same is the LC3 Hot plug. OS plugs are short body plugs, they will work but you might be chasing the tune all day long. If you can't get RB or Novarossi plugs get an odonnell or a mccoy and you will be fine.

Thanks Chris.
I was unable to find any one local,in the end "A Main" had some which i have now ordered.

Hey Chris how did Nats go. The track looked fun as hell.

Hey man, nats were awesome! The heat and the altitude made it intresting for many people who have never raced at 6500 feet. For me I was just hoping to finish as close to mid pack as possible, I finished all my quals with no issues and made the 1/4 finals in truck and the 1/8 finals in car, both were better than mid pack so I was happy.

PIPE FOR KILLER 10
 

So Chris being in Colorado and I'm from Colorado, Denver area, and not finding the 2045 pipe setup in the budget, would you suggest the next best choice is the RE10? This is for the Killer 10. Is the 086 pipe a choice also? Or which of the 2 would you go with? Also what glow plug are you recommending? I'll be running 30% Byrons fuel. Any help greatly appreciated, Thanks.
