Seems like these cars will have a "break-in program" when new. - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

If you turn the gear indicator on and obey the shift indicator, you'll be surprised at just how low it wants to go, and once you're there, how much you don't actually need to shift, give just the slightest bit of throttle above steady state and it'll just carry on up a 10% grade like it's nothing.

That IAM must be holding at a steady 0.82.

i have. end up in 6th at like 30mph. people complain this motor sounds like a tractor, at that rpm, it sounds like a diesel!

i paid for a 7600 rpm redline, i'm gonna use the whole gauge!

I think I remember hearing something similar but it might have been on a Kenworth forum.

I bet it serves the same function as the max-efficiency upshift arrow. It actually works nicely. Boring, but efficient.

Yeah everyone loves the feeling of perpetual torque dip with no end in sight......

soundman98 · 07-26-2021, 12:47 AM

and then the term 'floating heads' comes into play from all the extra forces of lugging the motor...

i wonder where all the coolant went!

If you're just driving along with traffic on 50km/h streets like what 100% of my work commute is, the torque bump below the torque dip works just as well as the torque bump above the torque dip.

Please educate me on the different break-in procedures between the two.

two completely separate manufacturers that have their own proprietary testing/building procedures.

if IAG says you need to do xyz break-in, then that only applies to their engines. applying the same break-in procedures to engines built by subaru simply because they're the "same engine" is just an over-simplified way to approach this.

if subaru doesn't specificy engine break in procedures in their manual, then don't worry about it.

Ah shit, here we go again. Low oil pressure light

You were hoping for a useful feature? I'm sorry. That's not how modern regular cars are made. They figured out that most people don't know what to do with useful features so they make butt warmers and touch screens instead.

My favorite is Ford's oil pressure gauges where the needle only actually has two positions: low and middle.

Food for thought:

"In WOT dyno testing, likely the rings are seated by the end of the first few runs"

And a screenshot I made from a European car community:

I tend to agree, there's a limited time frame to correctly seat the piston rings against freshly honed cylinder walls. There are too many variables if the customer would be in charge of "mating the rings against the cylinder wall".
