Suggestions on how to break in bracket racing engine with Maxima Break In Oil? No dyno available to do it in controlled environment. Drag Strip use only - not street legal. Make x amount of passes and charge oil at the track?

What does break in oil do? If you know that it might help. What does the break in oil company say?

Since you’re asking…here’s my opinion:
Break in just like breaking in a new flat tappet cam.
Then drain, change filter, and refill with Valvoline VR1.
 
I ended up calling Maxima. Frankly I was surprised at the lack of product knowledge the guy I spoke to had. Spoke to a notable race engine builder and he said put 3 full power passes & long coast to the pull out. Change oil and I’m good to go.
 
Beat the piss out of it. Pistons rings break in the fastest and most effectively at peak cylinder pressure (peak torque), so send it down the track a few times or do some similar pulls on the street. Dump the break-in oil then use what you plan to.
