Break in ... yup another thread

Lock your doors to avoid break in. K? K.

Holy shit read his question, it's specific about a hill.

But most of the responses are not.

I did not see an option for an FR-S with a factory-run engine to the reccomended break-in mileage that you could beat on off the lot. Got a part number?

LOL at the still-alive "Italian tuning methods" of red-lining from the start.

the key to engine break-in is NOT operating the engine at a constant speed, or RPM.

The sole purpose to the break-in procedure is to seal the piston rings to the cylinder walls. This can only happen with high combustion pressures, and these pressures happen when the engine is forced to accelerate under load.

In a perfect world after a new engine is installed in a given vehicle, the car or truck should be driven on a vacant airport runway. The drive should consist of full throttle acceleration from a stop to approximately 60 km/h then brought down to about 15 km/h – with the throttle closed. Followed by another acceleration run to at least 60 km/h, followed by another deceleration to 15 km/h. This accelerate/decelerate process should go on for about 50 kilometres.

During the acceleration period, the piston rings are forced squarely against the cylinder walls, which trues them to each respective cylinder. In effect, the rings will conform to the shape of the cylinder.

The deceleration period creates a very low pressure in the cylinders (relative to the full power combustion pressures) and in the intake system. This low pressure is exposed to the cylinder valves and the oil that gathers in and around the valve guides. This low pressure (essentially a vacuum), draws this oil past the guides and into the engine cylinders. This helps lubricate the cylinder rings in excess of normal operation. The rings need extra lubrication because of the excess friction created by the break-in process.

Load does not equal redline, but that may be over your head given the above.

ETA: Full throttle also does not mean redline. Also over your head. Your own quote says nothing about running a new or rebuilt engine to max rpm from go. That you on the clowncycle?

It says full throttle, that kinda means redline. I'v never heard anyone going full throttle to 4k rpm on a 7.4k rpm engine.

During break-in, whats better?

1. Shift to the highest gear possible and use the brakes to slow the car.

2. Shift to a lower gear and use the transmission gear to slow the car.

Engine brake using a gear which allows you to coast down the hill at an appropriate speed without going over 4000rpm. Use the brakes if necessary.

Full throttle is pressing the pedal to the floor (regardless of rpm or how long you hold it there). Redline means not releasing the pedal (which is not neseccarily all the way to the floor) until engine rpm redline.

So, not the same thing.

How did I get sucked into this? This is way off topic.

Then you admit you are clueless? That's the first step, congrats!

I've full throttled in 6th gear without getting anywhere near red line...

I never would have imagined someone could confuse the two.

hahah Seriously though. WHY THE FUCK ARE YOU SUCK A FUCKING DOUCHE BAG ON THIS FORUM?!? Every thread you post in has some smart ass comment to someone else. Just shut the fuck up and if you don't have anything nice to say don't fucking say it.
