Beat on your brand new engine!!!!!!!!!!

[scalywag]

This guy has some interesting points?
He says that babying your new engine will only cause you to loose
power and gain blow by.
Beat the heck out of it early on, to get the rings to seat properly !!!!!!

He does make some good points, and maybe some poor assumptions... Everybody knows that rings that don't seal are bad, everyone knows to change the oil after break-in... Getting the rings to seal early is an obvious benefit, but I don't think there is any ground breaking news... I do agree with Him on the benefits of a warm engine... We know that you have to get efficient cylinder pressure early, but do it without harming the other engine components that haven't WORK HARDENED YET which is something that I think He forgot... Another thing that He forgot is that the people and Engineers that he is second guessing have much, much more state of the art facilities and resources... Another fact neglected by Him is that these people that he is second guessing have tested waaaay more than 300 engines, surely thousands of times more engines than He... These manufacturers understand what riding/driving on the street is like and what it's parameters are, and build their engines to " seat " in that enviroment accordingly... I think He has an inflated opinion of His engineering prowess, along with the desire to sell a few books by challenging people who could probably eat Him alive in the field that He has chosen to work...

When I was building kart engines, a new engine was run on my dyno under load for 6 hours! 8 tanks of fuel, 3 oil changes.

A hard load! I try to break them.

Then it's taken apart, valves are laped, rings replaced, light hone.

I put standard motor oil in it, bring it up to tempature.
Make about 10 hard pulls to 5500 rpm.

Change to systhic, fuel her up!

Let her rip!

Tuning begins, hard pulls all the way to 7500 rpm on stocker, 12500 on limited.

Tune tune tune tune!

Then if it's got the numbers I want it's ready!

If it's close I will sell it to local track racer.

If it's a good one, we would run it or sell it for top dollar, mostly state or natainal racer. Or local racer who has the cash. 2000.00 for a 5hp alky stocker, 3500.00 for limited

2 out of 6 never make it! They are taken apart, blocks are trashed or sold at track for someone else.

Start all over!

Blocks and carbs seem to have the most varation!

But the best breakin was a hard load! Very hard!

He talks about the first 20 miles of your new car or truck.
run it hard and dump the earl?
And here I was babying my new truck that has 900 miles on it.
When it had 15 miles on it, I let "Lightspeed" take 'er for a spin and
he put the pedal to the floor and opened her up!!!:eek:
I guess he did me and my rings a favor :rolleyes:

HARD on the trailer , in gear , at 2500rpm or less before they go to the lake. Dinosaur oil for break in. Once the rings seat good , which you can do at low rpm under load, then you need to worry about pistons seizing. Too cold, too hot, too tight, etc. Take your time with the rpm ( piston swelling) after you load the rings on the ramp or the dyno. :D

Damn Al, I'm disappointed................. I thought you wuz a REAL MAN............... 2 stroke carts, them old briggs'es iz fo' lawn mowin.:D :D :D

I was always taught if ya run them hard the first time they will break with all yer tools right there ready to fix anything that goes wrong.. and if she sets properly it is byfar stronger than if ya baby them.. so every engine I get after an initial close (rich) setting and locked down the tioming she gets the sticks incerted throught the floor boards.. drive it like ya stole it....
