I would guess since the spoiler goes all the way to the top of the rear fender where the I/Cs are located, that it should have some kind of air intake duct there ala GT2 wing but more elaborate.

Sorry, I should have been more specific. I was wondering how much downforce that wing provides over a GT2 wing or RSCS wing. Whenever I see a loop-style wing, it always looks more show and less go (or down in this case.)

In RUF speak, BTR is single turbo (K-27), and CTR is twin turbo.
Here are some numbers for your consumption.
CTR: 520 HP, 505 ft-lb (torque), 0-60: 3.5 sec. top speed: 218 MPH. RUF MSRP: approximately $280,000.
BTR-2: 420 HP, 435 ft-lb (torque), 0-60: 3.7 sec. top speed: 192 MPH. RUF MSRP: approximately $110,000.
As you can see, it costs more than double to gain 0.2 seconds in the 0-60 time, and 26 mph at the top end. But I'm sure it's all worth it. For me, I'm perfectly happy with my BTR. Here's a pic of my RUF.

Thanks for the info. Beautiful car!!!! I almost went for the black on black look (with my rims) but I wasn't to sure how it would look. Stunning now comes to mind.

Hi,
Some replies.
Princeton: The regular BTR and or CTR engines retain the OEM Porsche internals. In my case, the PO paid extra to RUF to change the engine internals (conrods, valve-guides, push-rods etc.) to titanium. Even then, they left the max. boost at 0.8 bar, for maximum engine reliability. RUF dynoed the engine at 426 hp at 6,500 RPM.
Boost hits at around 3,500 RPM. In second gear and third gears, it is a major rush. A word about turbo-lag - it's miniscule. RUF built the engine first, studied the power band and selected gear ratio in their transmission (RUF puts new transmissions in their cars) to (1) maximize low end, pre-boost grunt, thus minimizing turbo lag, and (2) maximize top speed. The engineering is a work of art.
However, no matter what, clearly the CTR is MUCH more car than my BTR.
