Bmwboy018 · 09-25-2007, 03:39 PM

Ok, I know this has been gone over and over, but I would like to know something... The M3 should loose 23% at high altitude so 414 x 77%=318.78
How much if any % does turbo loose on higher altitude guys? Please help me out.... ofcourse trying to figure out 335i vs M3 yet again! P.S forgive me if this has been answered but could not find my answer. Really want to know how much % turbo will loose, 1, 2,3? Thanks Guys

Turbo will not lose much if any.

It should be just as fast, though, because the air is thinner, so less resistance...

Turbo cars should have about the same performance at altitude...

Keep in mind Turbos were first used on Aircraft during WWII to achieve higher altitudes.

Not on their own tho... as WW2 aircraft turbos were used mainly for feeding a supercharger and according to my WW2 and flying crazy hubby and his friends

, there really wasnt any turbocharged aircraft in WWII that didnt have a blower integral to the engine.

Alt wouldnt be noticable tho high temps may..( 15+ Nevada summers
