Hey Chris, is Wolf still up there in Colorado racing? What track do race at in Col?

I am pretty sure I know the guy you are talking about, all I know him as is Wolf. He really only races at Rat Raceway, but I do see him there several times a year.

Yea, sounds like the same person, he does race at Rat raceway, where do you race?

I usually race at Rat 5 or 6 times a summer, they hold the annual Colo State Championship. Rat is a sweet location but it's the smallest track we have here and they don't have water at the track. I race a lot at the track in Colorado Springs where the Nats will be as well as out in Burlington, Co. Burlington is our largest track and since it's out in the middle of nowhere we can camp out there in RV's or tents for the weekend and really just spend the weekend partying :D We also have a track in Littleton that is at a hobby shop that does Sunday racing, it's in an open Park space so the track gets pretty beat up with people out there bashin around all the time. The town I live in (Longmont) has a Hobbytown that got permission from the city to turn the old BMX track in town into a R/C track so I hope that comes out good so I have an option 5 minutes away. If you need to escape the heat this summer you may wana drive up north and race with us. We have races scheduled every weekend all summer long with all the tracks and they have scheduled around each other so if one track is racing the others are not.

Yea, I would like to come up and race, my problem is, right now I have been off work since August, I had knee surgery in Aug, then again in December, so, I don't know how much time I will have left after I'm fully recovered from my surgeries.

Rb shark .21
 

Does anyone have any info on the SE shark .21 ? I run a c6 now and want a motor with great power but good runtimes. 14mm crank 3 port with a balanced crank. I know the c6 is a hard motor too compare too but the shark looks strong and the price is decent compared too the c6.

I just broke in my shark and it has TONS of power. Runtime is a lil better than c6 too. The Shark has a different power curve than the c6. It seems like it just gets up and is full rpm with no problem. Almost reminds me of how my e buggy is. Either way im sure you will like it.:D

Thanks just what i wanted to hear LOL. Thanks speedyrob

What % fuel are you guys going to run in the shark ? And does it come shimed for 20% or 30% fuel. I geting ready to drop the $$$ in the next day or so and im trying to find the best deal on the rb shark. Looks nice and with only 400 made im trying to jump on it. Cant wait for another great year with RB:sneaky:. Thanks Speedy

Im running 30% in mine with stock shims. I use 30% in all my motors for the most part. 30% seems to give u the lil extra punch on the bottom end. Also, try a short mugen header(MUGJX14002) with the 2045 pipe. Ive tried it on the c6 and it really opens the motor up more and it doesnt seems to lose hardly any bottom but it screams alot harder on the top end.

Well if you happen to miss out on a Shark there is no need to worry as the new Cross10 coming out is basically the same engine. I think I saw A Main has the Shark on sale right now.

We got some snow here in salisbury nc and i didnt get to get my money yet. So im going monday to get my money and i hope a-main still has it on sale im keeping my fingers crossed:lol:. I love hearing that rb's geting ready to release a new line IF thats what you mean:sneaky::lol:. I cant wait to get it a friend today that just got a speed was tryin to talk me into a v-spec, speed, mugen jx. He said i really never see anybody running Rbs anymore. I told him its because they cant handle the Power so they get a smooth slow OS:lol: but i love running things that other guys dont have makes me feel different. Cant wait hope there going to be some parts for the motor but it sounds like there is. Thanks guys Speedy

Quick question? I have a new C6 with the T7 on the head. Which L2G head can I put on this if I wanted to? Or can I even do it? I have a WS7III L2G motor, is that head the same or would I need to pickup a new C6 L2G head? I realize it's not really needed but with the slammed bodies out now it might be better to put the lower head on it? Been running RB for years and love them. :cool:

You can run any L2G on there, they will all fit. It would benefit to find a "9" series over the original L2G heads since they are lighter.

I did it guys i ordered the Shark 9 today at amain for 424.99 with a 25$ coupon i got it for 399.99 WOW:eek:. I cant wait to break it in and run it this year in the North Carolina champ seires. I hope it got power like my c6 i well have it as back up this year as i only have like 5 gallons on it. It well be ok to run 20% or 30% with stock shiming right? I may try 20% this year to get more runtime out of my motor not sure thought. Thanks Speedyrob GO RB 2010

Thanks Aaron just the Info. I was looking for. May get a Shark 9 as well and keep the C6 for a backup/practice motor. Is practicing with a diff. motor a bad idea?

Yes to the questions and you made a good decision with the shark.:)

I know ill be happy with the shark its a RB :lol:. What conrod well work on this motor? I know after i break it in ill want to change the conrod,wrist pin and maybe bearing to ceramic bearings. I sure it well last a long time like all my Rb's do. Speedy

he guys, i have an rb 2020 pipe wth a 192 header,i would like to khow if this combo is a low,mid or high end. i just wantto make sure i use it with the right engine. thanks

That is a low end pipe and they also sound really cool.

Chris, I ran the C6 I was talking to about last week, went with the needles almost flush as you suggested, temps went to about the 230 range, perfect. next question, how about the Killer 9, what are needles on that looking like? If you do not have one, any help out there is appreciated, temps are decent, still real new, maybe 2 fuel bottles, but, just isn't right, sounds lean, plenty of smoke, of course it will, I'm breaking it in with 20% Byrons, with the higher oil content, Engine runs around 200-230 range.

Tony
I would take a guess and I would think Chris would agree it will be light years different than the C6 tuning wise if the carb is different. My god you know I have to work during Nitro Challenge do I have to come there and help you with everything lol:lol:

RB C6BB-T7 EB Mods Engine Carb venturi
 

Just bought a EB Mods C6BB-T7 and I see there is no Venturi inserts in the Carb, does anyone have any info on this? Is this correct?

The stock T7 comes with a 9mm carb with a 7mm (T7) orange plastic venturi. Ed may have dyno-tested the 9mm for maximum performance. If that's the case, he might now have a collection of orange 7mm and 8mm inserts. :)

It's lean out of the box, for easy cold/new starting. Once you race tune it, it should not sound as lean. Just take it easy at 75-80% (max) until you get at least a gallon on it. Then it will really comes to life.

My K9 needles are currently at about 1mm in from flush on top; 2.5mm in on bottom. I'm running in a dry 40-50 deg F climate. I use the OD97T plug for an all-day spitting idle. If you use anything hotter, like an OS-p3 it will run lean.

Thanks

took my O'donnell Zo1-t and RB B9 2045 pipe combo to Motorama this weekend and man was I happy! I started the day with the carb HS needle at a about 1.5mm above flush and the low speed in a bit from flush maybe 1.5mm or so. it was low lean idling on the low end and i had no top end when my practice started so i turned the bottom out to flush and the top in a few hours and it ripped low-top end was great. i had to lean the bottom 3 more hours so it is barely in from flush. i am very happy with this engine i ran a 7 minute qualifer and had 40 % of my fuel tank still full, 11 minutes maybe;) i ran the OD 97t plug, great plug!

Awesome... 230 is right were you want to run these engines, on really hot days I have got up around 240-245. As for the K9, I don't have one but I have heard the LSN generally has to be run fairly lean on those. Try the settings others have suggested. As long as you lower the idle as your leaning the lsn you should be able to tell when it's just right, as it should accelerate nice and crisp without loading up. You may also want to run a bit more fuel before you start trying fir a race tune.

In truggy you should be able to get a good 11 minutes with that engine, doing timed runs several times I have gone a little over 13 minutes on some tracks.

I just got a RB s7. I havent broken it in yet, should i follow the "break in bible" verbatim? looks like it only says to do about 14 tanks before tuning for a race?

Also does anyone have a used 2045 pipe and header?

do you guys now if they sell a turbo button for the rb s3

I have not read the break in bible method but as long as it is a heat cycle method of break in that has you heating the engine up prior to starting the engine and getting the temps up around 200. RB's generally take more than 14 tanks before they are fully broken in. You should be able to put it on the track after 14 tanks you just shouldn't fully lean it out yet, after about a gallon it will fully free up and you can lean it out more at a full race tune. The key is to be patient in that first gallon and don't expect too much out of the motor, when people try to lean the engine out too soon is when premature wear happens.

I am pretty sure I do have a 2045 pipe that would work for ya, it is slightly dented but it still works fine. PM me if you are interested.

They sure do, the part number is 01080, and it looks like A-Main has them.

thanks

Shark 9
 

Got the shark yesterday and ill i can say is WOW:eek: motor and everything look GREAT just like always. I seen the manual say to add a .1 shim for anything over 25% nitro and im going to add one to be safe. Do you guys knoe any thing about the RB engine protecter #02010-001 looks very nice and i think it may make our engines last even longer. I was wanting to know if it would work with a Losi clucth if so im trying one out?? Do you guys think that less nitro = more runtime????

What is the difference (besides what is on RB's website) between the B.9 H.9 J.9 S.9 and WS.9 I have been out of the hobby for a while and I am a big RB fan. I have always ran a WS7 so I guess all these knew motors in comparison to that. Also is the WS7 3 a big difference. Whats the most and least powerful or what are the different power bands. Thanks

New vs older naming.: B9=C6 WS9=WS7 S9=S7 H9=S5 J9=S3 same engines other name for as far as i know.

anybody know the best pipe for a RB S9 and the rear bearing size?

Use the RB 2045 pipe with the 192 RB header, the crank bearing is the same as the WS 7, 13 x 25, there the same as S7 also.

Here is the Rb site link for you. http://www.rbproducts.com/mainEn.php...oduit=01009-S9
