Hey don't know if anyone told you but the calculations
HP loss= Elevation in feet
--------------- X0.03
1000
X sea level HP
For example a car driving at 8325 feet and rated at 255hp @ 5200rpm
HP loss= 8325
------ X 0.03 X 255
1000
=63.69 - 255hp
= 191.31hp
hope this helps you
^ that's quite interesting to know. good first post, thanks!

Hp is not lost because of increased temperatures or because of increased hight.
It's lost because of reduced air densety. If you drive on a hot summer day with low barometic preshure in the lowlands it could give the same output as a cold day with nice wather and high barometic preshure in the montains.
It all com down to how much particles of air (mass) you can get into the cylinder.
If you run a supercharger you will expereince the same % of loss as with a NA engine.
If you run a turbo it depends on the wastgate. Is the wasgate working with barometic preshure as reference it will experinece the same loss in % ,but if it use absolute preshure as reference it will compensate for the reduced air densety.
Oldish thread,
But relevant question. The hotter the engine runs (within reason) the lower the emissions and engine cylinder wear.
The C5 ZO6 Vette for example had the 1st cooling fan set to come on at 108c and the 2nd one at 113c!
(See attached thumbnails for detailed explanation).
Most car computers are set to pull timing as a protection measure if the ECT (Engine Coolant Temp) goes too high.
Running hotter can run you closer to detonation, but with decent fuel it shouldn't be a problem.
It's Intake Air Temp that can and does cause loss of power as it increases....
Intake Temp.........Power Loss.......Example Power Output
20oC......................... 0%................... 400hp
40oC......................... 3.5%................ 386hp
50oC......................... 5.3%................ 379hp
60oC......................... 7%.................. 372hp
80oC......................... 10%................ 360hp
100oC....................... 13%................ 348hp
