New Engine Break In Procedure ~ With Poll ~

[mushroom_toy]

Alright so what is everyones opinion. I already know Tim's lol. Some say beat on it and give it hell for 20 miles, others and this is along my train of thinking say to baby it for the first 500. ie. keep it under 2500rpm city driving. What would yall do. Starting from initial startup.

don't ever granny that bitch.

[2drSE-i]

From what I'm to understand thats the way to do it. Bisi sticks his on the dyno and just runs it for 1000 miles at altering RPMs.

Call up / e-mail some engine builders regarding break-in; the vast majority should recommend the "don't go easy" route...

[89T]

and loads...

dude i ran mine hard after the initial and I came out with under 4% leak down a year later.
I dont fuck around i run mine hard every time out.

[89T]

pauls right,call them up.

think nhra----dragsters.3-4000 hp broken in, in the pitt's.

[mushroom_toy]

True. Im calling the place where I got my engine bored out and such and gonna ask the resident Honda expert tomorrow. Also think about the race engines though. A lot of professional builders have money to spend on a new engine ever 1-4 trips down the track, so getting the engine built and broken in fast as hell is there main thing. Doesnt matter about wear, because theyll be breaking it down again fast anyway.

[mushroom_toy]

And people vote in the poll lol. Trying to see if itll turn out 50/50 like every other forum/website ive seen today lol.

[Dr_Snooz]

Do the Motoman break-in.

Actually no they don't have the funs to keep rebuilding motors. They usually wear other parts of the motors out or mess up in the build process/random part failure.

look at JJspec's teg. A d-series with a huge ass turbo lasted lots of passes on a stock rebuilt bottom end with a GREAT tune.


And Luke i told you just about everything these guys said via text today. I told you i did my research YEARS ago. Before i even thought about getting the accord, and before finding out it had 83miles on a FRESH rebuild.

it seems giving the engine the beat down is the way to go. But is it different on different engines, like how a b20a has a bad rod/stroke ratio??

I'd highly doubt the procedure would differ to a undersquare vs oversquare engine, the only real difference would be a slightly faster piston speed in the undersquare one...

[2oodoor]

i wouldnt beat on it to hard remember is aint a high revver design, but baby it is not good either, just listen and observe what it is doing until bugs worked out.
decelerating on grades is good, up hill then a long coast down then up. breaks in rings good. rinse lather repeat.
project sounds like it is moving along nice... awesome

If you're putting in a new cam and rockers then you might want to let it run at a high idle for a few minutes before you open it up. Also consider using Shell Rotella-T or another diesel type oil that has higher levels of zinc phosphate to keep the cam from wearing too much during break in.

If you aren't using a new cam and rockers then fire it up and flog away.

Looad is they key.

Dont try and brake it, but make sure theres somewot action going on.

I use rotella in my bike, and I might use it for every oil change in the car on the new engine as well. Its great oil in my book. But yeah running new cam, used rockers.

under load huh....maybe I should hook my trailer up with the bike on it.

Torco makes a KICK ASS break in oil. Check out Bisi's 700HP Wagovan build for details.

im a fan of Royal purple, so i would say use some of their break in oil haha....

and isnt the cam reground not new?

[mushroom_toy]

Probably want to do the first 1,000 miles or so with a regular, non-synthetic oil. The synthetic oils are too slick and will keep the rings from breaking in.

[Tdurr]

no no, snooz they have special oil for breaking in a motor. Then after the first oil change ur switch to the regular stuff.

[Dr_Snooz]

Oops. My mistake.

[Tdurr]

hehe is all good man. not alot of ppl kno that.
