Default Can someone explain to me this method of break-in?

http://www.cefx.net/tips/nitro/break-in/index.php

The link above describes a method of break in that baffles me. It involves repeatedly running the engine at full throttle throughout the entire tank of fuel . Am I reading it incorrectly?

Your reading it correctly. Its Full Throttle, but with a very rich HSN. With it very rich, you wont get a very high RPM.

The way I and another guy at the track do (our engines last up to 2 years before they start losing performance) get some 5 or 10% nitro with out synthetic oil and richen the engine so it can just start and do one tank just on idle then let to cool for 15-30 mins then (if no one else is around at the track) start you car and drive it around the track running as rich as possible without pumping the throttle too much and finish a litre like that but have 10 min breaks between each tank. then let sit till it cool or even a day then get the fuel that you will race with and do a couple of tanks running rich. then tune you engine for racing (there are tutorials on this and how to do on sites like www.rccaraction.com) and then you can go as hard as you want.

Oh, well thanks for clearning that up, sparsky. It was confusing me for a second there.

And thanks for the tips, Chris. I appreciate the input.

If you break-in a engine in the 1st tank make it idle then the 2nd tank run it full throtle until you broke your engine lol......

The Josh Cyrul method in the first post works really well. I have done 4 engines this way & have been happy with the results. I must admit I was nervous the first one I did.

I used Josh Cyrul's method with my LRP and it is still going strong.
Bloody hard thing to do first time though, I had to hold the throttle with both hands so I didn't let it go

The best thing about Josh's method is it is relatively fast, because they are running so rich a tank only takes about 2mins max to use.

It does sound crazy to me. <_<; But after hearing the positive feedbacks I think I will give it a try on my next engine too.

I've used it twice now, and it seems to work very well. I really like it alot better than a regular heat cycle method, it seems to make getting the engine in the right tuning range alot easier.

I found that too. By the time I hit the track it was not far off being spot on.

Also the first engine I did like that (RB V12 Rody) is still going strong after about 15 litres. It has had 2 maybe 3 plugs changed in that time & only flamed out a handful of times (usually when cold)
