So if there is a 750hp engine, the next engine may be a 22.5HP differencial between the next one and the one previous to it.
Generally the engine manufacturers give all engines a 100km dyno burn in to get what power the engine pumps out. What usually happens is that each engine manufacturer provides 8 engines per car for the season, so thats 6 cars per manufacturer, whitch is 48 per season.
Pre Season usually sees each team getting 5 or 6 engines and post season each team usually gets an aditional one, Ferrari teams use 2 seeingly post season. Thats up to a maximum of 18 more they have to manufacture.
Thats arround 66 eangine per season that see action on track. If we make it 70 per season if one or two pop their clogs.
Toyota and BMW used to produce at least one engine a week for dyno testing as well, thats another 52 per year. The Toyota engine plant used to have 5 engine build crews as it took 10 days to produce one engine. At the time Toyota provided the works team and Williams as well, they produced their engines in 10 blocks of 12 each year, the 4 best going to races, the next 4 to testing and the others to Dyno testing, once they knew their total peak power from the 100km dyno testing. To think the best RVX-06 to RVX-09 engine that was produced was a rumored 757hp, with the average being 748HP, as Toyota had the most consistant average of all engines, arround 1.2% distrubution between all engines.
I remember there was a Toyota docu-soap on the Discovery Channel arround 2006/2007 and one of the engine guys was talking about their engine and their engine power band. If i remember there was about 5 diffrent episodes, all concentrated on 5 diffrent areas of the cars development and all about the Toyota - One Aim ideal.

Maybe the figures are simply a matter of what and how its done-for example are all engines optimised for individual engine specific fuel and ignition maps or is it considered not being worthwhile to try this in the light of them being one like another?
I think we should all step back and reconsider what is achievable in a world full of unavoidable variables and tolerances and to claim something like a .5% of deviation when you cannot even measure with this precision is quite a statement.... at least when not aired by Lewis Hamilton or Norbert Haug....no offense ther but I consider these as non technical but enthusiastic guys .
