Re: What is your opinion on MotoMan's Break In Procedure?

Although everything people are saying in this thread sounds knowledgeable and backed by some facts, I just cant for the life of me picture myself doing 5 WOT runs in a row with like 6 miles on the ODO. First off it is VERY critical as woosch stated that the transmission and differentials are worn in correctly. And I can assure you that 5 sustained WOT runs 1st through 3rd will be assuring everything BUT proper break in for those. To be honest I would rather have my tranny and differentials broke in more properly then my engine. Main reason being is regardless of how a motor is broken in (as per the manual or by the WOT runs), the engine will be reliable for as long as your gonna own the vehicle. That car will be on its 5th owner before any evidence of how that motor was broken in shows up.

You guys can do what you want but when I take delivery of my Overland in a couple months the last thing im gonna be doing is flooring the $hit out of it. Im going to drive relatively easily with VARYING RPM's (that to me is whats key). Always ensure fluids get up to proper operating temp before doing anything crazy.

James

Re: What is your opinion on MotoMan's Break In Procedure?

Immediately after doing a ring job there's an important and highly specific break-in procedure. Ever seen the movie 'The Gods must be Crazy'? That'll give you an idea of the extreme case!!!
However for a new vehicle, I personally wouldn't stray too far from the recommendations in the owners manual.

Re: What is your opinion on MotoMan's Break In Procedure?

People act like their new vehicle isn't driven before they get inside. The engine is tested after assembly. The car is brought up to cruising speed at the assembly plant for system checks, left idling for awhile to check for leaks, and then driven on a small course to check for rattles. The its driven into a parking lot, then driven onto some transportation, then driven by the dealer....

The whole floor the thing immediately after you build the engine isn't even applicable to this situation.

I think there is only one thing you have check - wait until the temp is high enough - then you can do with the engine what you want ;-)

Re: What is your opinion on MotoMan's Break In Procedure?

We have an 04 Durango that I broke in doing the varied RPM/heat cycle method, it has over 200k miles on it and still going strong. Never any oil burning issues, still the original motor, tranny, transfer case, and diffs.

The second key to making any vehicle last is doing all the required service at the right intervals.

Re: What is your opinion on MotoMan's Break In Procedure?

I recommend reading:

http://www.mototuneusa.com/break_in_secrets.htm

Having said that, make sure you read the WHOLE THING before you get started. What you are looking for is NOT high RPM's. You want lots of load and a very open throttle.

I've been rebuilding & tuning race motorcycles for years (mainly 2-strokes) and have used his technic on all of the engines. Since our bikes get new pistons and rings every 200 miles it is easy to determine which method works best. His method works very well for getting the engine ready for full race conditions very quickly. It also seems to give the best results (i.e., most power) once the engine is ready to race.

Re: What is your opinion on MotoMan's Break In Procedure?

My response was aimed at the brake in of a NEW engine... I missed the part that said it was for a new vehicle... BUT I still believe it should be run HARD if you want the best overall performance.

My 2002 4.7L Ram was ALWAYS faster than the average 4.7L Ram. Many felt my truck was a "Factory Freak" because it just outran most 4.7L and with minor bolt ons was nipping at the heels of the HEMI Rams. Topped off with the fact that it always seemed to get great fuel economy when that was the goal, even able to average over 21MPG with mixed city/highway driving over 4 tanks of gas.

I honestly believe it’s because my 4.7L saw 6,000RPMS about 6-7 times a day for 140,000 miles... I ran it hard right out of the stealer ship parking lot and never left off the throttle. I swapped over to full synthetic Mobil 1 at the 500Mile mark and never looked back changing the oil every 3000-4000 miles.

Believe it or not, running an engine hard is GOOD for it! Over revving it, letting the fluids get old or not insuring coolant is topped off is NOT good for it. As long as your fluids are topped off and fresh, run it like you stole it every now and then. Your engine will reward you for it.

SPEED SAFE, NICK
