Like the tile says... I'm looking for the frontal area and coefficient of drag for a 951 (either measured or published by Porsche).

Anyone have those #s?

(I'll trade the CG height for them!)

I have an old magazine review that puts the drag coefficient at .31 - but let me double check.

I think you're in the ball park, Mike. I found this:

Turbo Cd with rear wiper 0.33, without 0.32
Frontal area... sources all say 1.89-1.90 m*m

+1 cd .32 not sure about the frontal area though.

DanR

so Van, what are you up to now?

Oh, you know... playing with data acquisition and lap simulation.

I've seen 0.33 for the 951/944S2 and 0.34 for the 968. No idea on the frontal area, though.

A clear bra manufacturer might have that info for you, though!

It's been a while and I'm not about to dust any books off, so I'll go with what's available on-line.
There is a listing for the CdA of a 944S at 6.96. CdA is obtained by Cd * Area (A).
So A= CdA/ Cd. seems to simple.
It puts us around 21ft^2 to 23ft^2, with the assumption the 944S has the same Cd.

Van, I found an original factory brochure (30+ thick pages) that puts the 951 at .33 drag coeffcient and a frontal area of 1.89 square meters
