951 track car engine break in, whats your procedure?
 

What do you guys think is the best break in procedure for a 2.5 litre alusil 951 track car? I will be doing first startup hopefully in 2 months or sooner, After verifying oil pressure before startup, then start and runn @ 3k rpm for 20 mins , change oil and filter, then alternate from 2 k to 4k on low boost over and over again. then, 3k to 5k, then, 4k to redline, all while letting the car decell in gear? I have extenisive mods to turbo, pistons, exhaust, clutch and head, as well as fuel and engine management, I am looking to break her in so I wont have low compression in the long run because of crappy ring seating , what do you guys think? what did you do different or the same? hows is the engine whith oil consumtion after "xxxxxx" miles. I am using wossner pistons with coatings on the skirts for alusil. I would also like to know what boost you did the ring seating inSmileWavy

The spec guys I know just take it out on the track and drive the heck out of it. After one or two 20min sessions the rings have seated pretty well.

Not sure about turbos, but I would expect it to be pretty similar.
