The K9 is a killer mill, but the ofna jl 21 is the same mill for lower price. You can get a modded JL from Clockwerks that will be a beast for not much more if I remember right.

plug choice
 
Hey guys. I've got a RB 5 port and a Novarossi Rex P5. Both old, non turbo style engines. It's been a while since I bought plugs for the RB and the P5 is still NIB. What plugs are you or have you ran in either of these mills? One of the local shops has these SH plugs, anyone tried them? Thanks for the help.

Both engines run a med plug stock, the SH plugs should work fine. OS non turbo plugs are short body plugs and will not work in a Nova based engine. McCoy plugs will work, Odonnell will work, Novarossi, RB, basically anything that isn't OS or made for OS standard engines.

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.
