Rebuilt 2.5 motor break in

[Nine8Six]

Hi Brian! No specific performance exp with Porsche cars here, they look good! Your sig has a whole lot of them, your 1st pcar involved at the track?

best ever advice I've had...

Cycle/warm-up at the same time of the day (if you can loll), at the same temp and for the same duration, before load (be accurate and consistent). If its 30min before your first session that you normally warm-up the engine, then warm-up 30min before your session for the rest of that engine life. Equally important to keep a consistent cool-off routine.

Should last forever.... if your eng builder have not forgotten to refill the windshield washer fluid of course, which I doubt he would have forgotten anyway.

Alloys loves routine. it rarely gets tired of it

We want to see hot pics only, post some when you get it out there

No not first track car, third one. First Boxster track car after switching from 944. After eating 2 motors in a year, starting to wonder if that was a good idea. This motor is a solid rebuild, so I have hope it will last for a while.

2 engines in a year... wow :/

Makes me question whether the stock "flat"-6 design is an handicap on the circuit you normally go too (mass moment of inertia). Do you have many corners exits that requires very long & hard acceleration? Just wondering because others seems to have pretty reliable results when tracking their M96 eng on other (smaller?) circuits.

If that'd be the case anyway (I doubt mind you), beefing up the assembly would be remedial to this F6 design issue

Have you found the answer to breaking-in the engine? I'd expect quite a few very fine particles in the oil for the first few flushes. Unavoidable, although the filter would catch most of it if not all.
