You can build a spare forged engine with their price plus they tend to fail if detonation occur!

No thanks..

So how is max MBT figured?

Can someone please explain? I tried looking into it but best I could come up with was doing "ignition timing sweeps."

Is this where you do multiple dyno runs where you keep advancing the timing and watching the HP increase each time until it stops increasing?

I can see how this would be easier on an engine dyno versus a chassis dyno. Maybe Dynapack style?

Yes, you start retarded and then increase timing until you find it reaches a plateau then for safety you can back it off 1-2 degrees. I tune on Dynapack but chassis dyno also works.

Keep in minds that sometimes depending on your fuel octane you may not be able to reach MBT without detonation.

MBT = Minimum best timing or Maximum brake torque.

So let's say for each 1 degree advance you pick up 10 hp on dyno. Eventually each degree given will not get you 10 hp so you will know you are getting close to MBT.
