I see people telling us about there stock dyno's and everyones not the same. i was wondering if this was due to how the person broke it in during break in period?. If someone was just to rip on it since the day they got it is it possible that they will see more/less horsepower or if somone babys it and never shifts passed 4000rpms for the first 1000k will they have more/less horsepower

 

I really dont see how that would effect it... something would have to be wrong/broken to see less than expected. Everything is a variable, from temperature of the air, to the person driving the car... its not going to be perfectly consistant all the time.

Though there are some who believe, me included, that a proper break in will result in better compression, so more power, for the life of the engine. Though, when I say "proper break in" I mean, bring it up to operating temp, and then do several full throttle, full rpm range, passes in as high of a gear as feasable and safe. Ideally, that would probably be 4th on a dyno. The reason for this, is because the only wearing parts in a break in (hopefully they are the only touching parts not suspended in oil) are the rings, and you need to force them into the cylinder walls with some force, to do an initial wear fast enough for proper sealing. I know this belief is controversial, and definately unconventional, so do your own research please.
