"Real World HP" dynos LFA at 480 ~ 490 wheel HP in 5th gear@ 173 mph
#16
I've been doing this a long time, I can tell you first hand, it wouldn't have made more than a negligible difference in power having the fans on or off.
However, there is a pair of large ducted fan in the front of the trailer, just out of view of the camera, it likely wouldn't have mattered much on or off.
That large fan in front of the other dyno is doing ALOT less than you think. It's blowing a large cfm of air "at" the front of the car, but hardly much if any of it is actually making it through the grille, radiator, etc.

I'm sure this test was from a while ago, but I either didn't see it or forgot. Anyway, amazing that both the LFA and MP4-12C make 515 rwhp, given the MP4-12C is rated at 592bhp compared to the LFA's 552.
Also amazing is not only how flat the LFA's torque curve is, but how linear the hp curve is. The graph just shows what I and other LFA drivers have discovered through experience.
