If you wait till there is no metal pinch when the engine is cold you might be running 3 gallons of fuel thru that thing in your street before you get it to the track.

I run them much harder during the first 2 gallons then you show in your videos...... As the engine loosens up you will see a couple things happen.... One is temps will gradually drop, the more you run the engine, the cooler it wants to run... And the more you run it, the higher the idle becomes unless you lower the idle gap........Judging from your video it is going to take you quite a long time to breakin the engine... Your doing too much sitting and idling and not enough actual running.......

That makes sense. I had a few RB C6's...



Is this Neal, from RCCNA?? long time right?? LOL

The video is just a clip and really is just a snapshot of me running it, I spent most of the time going over the camcorder with my Son :o. I am running it harder than that really and there is healthy smoke, but I get the feeling what you're saying is "RUN THAT BITCH!"? :nod:



Question....I gather you are saying it is healthy for the engine to run it CONTINUOUSLY, considering the conditions are maintained good smoke, good tune, good temps and this will make the engine run optimally in the long run? I don't want to take forever breaking this motor in (I have a BTT mounted up in my RC8.2 waiting for its first taste of Nitro so I have my work cut out for me) and I want it to run like a raped ape, just want to be clear. I have jacked up a few motors in my time. :o

IMO the engine has to be run somewhat hard in order for the piston to seat.... taking it too easy just prolongs the breakin and sometimes leads to the piston not seating correctly......Now I am by no means saying t beat on the engine either, but the engine does need to be run and loaded to breakin correctly......

I went with Adam Drakes advice from this video for my truggy. I am running the 9853 pipe and the 41021 header C6TGC plug 7mm venturi on my Bonito. He goes over it in the vid.

Understood, thank you.

Any opinions on the nova p3xs? Looking for an engine to run this winter indoors. How is the fuel consumption and smoothness of this engine

I have the 9853 pipe on mine. I have a werks conical header set(3 different lengths) and I'm currently using the medium length with the 9853.

Just started break in on it today:

I'm sure a lot will disagree with my way of break in but it's worked for me for about 10 years. I explain it on the video description.

I have heard "if you ask 100 people how to break in an engine, you will undoubtedly get 100 different answers." Here is what I go by, good smoke, good temp, good tune, good idle, good to go.....do what ya do Bro, nice vid :nod:

Matt, don't tell me one of your dreams ISN'T to having and RC track in that huge back yard....:ha:
