Stephen Bess Break-In Method
 

I really do think the Mods might want to put a lock on this and keep it at the top, Just so that we dont keep getting the same questions about breaking in a motor. Just food for thought, Mods.


Try the "Bess" Method (Credit to Stephen Bess)-

From the very 1st time you start your engine, plop the car on the
ground & begin running it in a parking lot in 2-3 minute intervals,
tuned only *slightly rich* getting the temps up in the 200F range on a
normal day. Every 2-3 minutes, shut the engine down & let it cool
completely with the piston at BDC, and then fire it back up; continue
this cycle until you've run 15 min or so, and then bump up to 3-4
minute intervals. Vary the RPM and don't be afraid to get the temps in
the 200's. What you want is heat cycling of the components without the
incredible stress that comes with breaking an engine in when it's
overly rich & cold. After cycling the engine in this manner for about
20-25 total minutes, it'll be ready for the track and race tuning.

Seems to be the method everyone is using now a days.Im gonna try it on my WS7II.

RE: Stephen Bess Break-In Method
 

yeah, i like the sound of this method also. i broke my S7II in by the iRB instructions reccomendations, and it was devistating to stand there and watch it gurgle through 3 tanks.

RE: Stephen Bess Break-In Method
 

You can break in an engine in many ways but you can do as you want as long as you run the engine rich and dont do WOT runs for the first few tanks.

I just start the engine with as rich settings as possible and drive the car on the ground without going WOT.i then drive a tank let it cool down completely and then drive a few more tanks.
And when i am on the 7-9 tank i start to tune it and when tank 13-15 is complete the engine is tuned and ready to race.

RE: Stephen Bess Break-In Method
 

That's the hard part for me when i'm breaking in an engine. The temptation to yank it WOT is hard to resist after a while. Patience...

I just broke in my new Top P5 using the Bess method because it just makes sense.

RE: Stephen Bess Break-In Method
 

Funny that, Coz that is the Picco method, Bess stole it. But if you want it pinned then it should be moved to the RC Car Engines forum and not in this one. Then we can just link to it instead of it cloging up the 1/8th questions.

RE: Stephen Bess Break-In Method
 

anybody know how well this works? i might try it on my hyper 21

RE: Stephen Bess Break-In Method
 

Actually it's an ENGINE, motors are electrical and engines are internal combustion. I have never heard tale of anyone breaking in their engine in that fashion though. Personally I prefer a few full tanks of idle before I even think about running the engine with a load on it. It sounds more like this method is part of the impatient generation wanting thing their engine broken in as fast as possible. I have all the time in the world to get my engine broken in so how long it takes does not matter to me.

RE: Stephen Bess Break-In Method
 

El Pirata, your method is simply causing you premature wear because the motor is not getting up to temp. If it is not warm, it is not expanding properly so it is simply wearing the piston down faster while its cold. I don't care how much oil you have in it, it won't save it from the metal to metal wear. Will it damage it? Nope, it will just have slightly lower compression at the completion of your break in than mine will.

I do pretty much what bess does only honestly, I am not gentle with them at all. I used to idle through tanks for ever when it was all that was pounded into anyones head. About two years ago I started breaking them in hard and not worrying about it. Well, I am much happier and I am definately not seeing any shorter life span by doing this. I don't use this with cheap throw away motor's either. I am talking out of the box V01B's two years ago hitting 240 on the first tank and running the crap out of them. Same with all my RB motors now. It's just works better for me. None of the methods are really going to ever be sold to every one as the only way though so in short, do which ever one is most comfortable to you.

RE: Stephen Bess Break-In Method
 

Geez!





Well said Slodsm.

RE: Stephen Bess Break-In Method
 

El Pirata...its 2004.

RE: Stephen Bess Break-In Method
 

Ok, the Earth is flat, whatever. I get more than 10 gallons of 30% fuel with only 10 - 12% oil and the engines running low 300s the entire time using this method out of my engines. If could be possible that the $400 engine could be a determining factor but I still had about the same lifetime out of k-mart priced engines as I get with my $400 engines.

a banged up ford escort can be a motor if you like:D

RE: Stephen Bess Break-In Method
 

What's that have to do with anything kid?

RE: Stephen Bess Break-In Method
 

actually it was more in reply to skyline 350gt, we posted at the same time

RE: Stephen Bess Break-In Method
 

No clue what you are saying by that but it's cool beans.

RE: Stephen Bess Break-In Method
 

sorry i need to translate, its southern english:D motor= slang for car
so it doesn't really matter whether you call an engine, a motor, a lump or that hunk o' metal that makes it go.
and i happen to agree with you on the break-in i'd rather do it slow and careful

RE: Stephen Bess Break-In Method
 

So it's kina like asking someone over there for a fag? Or say ring you up?

RE: Stephen Bess Break-In Method
 

nope sorry lost you there[sm=confused.gif] a fag is a cigarette over here not sure what is over where you are, and ring you up isn't really all that common, drop me a line, give me a call, give us a bell but not ring me up!!

RE: Stephen Bess Break-In Method
 

Sorry when I was growing up I had a buddy from the UK and he used to ask for a fag and ring me up all the time. I imagine the language has changed over the decades since then or at least the terminology.

RE: Stephen Bess Break-In Method
 

yes but only slightly, fag is still most common but ring me up's gone out

RE: Stephen Bess Break-In Method
 

So I suppose "knock you up" is gone too?

RE: Stephen Bess Break-In Method
 

El Pirata..First off if you think im a kid thats awesome..I'll take that compliment...

Second...I HIGHLY doubt that your gettin 10+ gallons on Original internals running 300+ degrees with 10-12% oil. HIGHY DOUBT THAT! I actually own a property over in New Port news Beach, VA..Maybe next time im down there ill "hit you up" and you can show me one of these infamous 10+ gallon motors than ran above 300+ degrees from first fire.

RE: Stephen Bess Break-In Method
 

yep, sorry if i'm guessing the right meaning it's now and you're gonna laugh at this one, bang you, which happens to have a less offensive and more 'passionate' meaning:D it's quite funny when you get the typical hard man wannabe going 'i is gonna bang you hard now':D

RE: Stephen Bess Break-In Method
 

Actually MOTOR is an accronym of Method Of Transport On Road. Also in the fatherland of engines they are indeed called Motors. So your statement is not correct.

As for the break in method. It works for Piccos but not on Hyper 21's or NR 421b's So I do not recommend deviating from the instructions that come with the engine/motor. Manufacturers test these systems and write instructions for a reason.
