It's not a 964. The Ruf CTR1 "Yellowbird" was built on a seam-welded 3.2 body shell, with a 1972 oil-door/tank added and lightweight bits substituted. They then added twin turbos and many other goodies (including a gearbox of their own design) to a motor that originally started as a 3.2 N/A:

Yellowbird, as the prototype car, had NACAR vents on the fenders for the twin intercoolers - which actually emitted air, as opposed to letting it in - as per the original intention.
This is a later Ruf - no NACAR vents, extra cooling slits on the rear bumpers, rarer round brake ducting holes:

Alois quoted 469 BHP for the CTR, but Yellowbird so comprehensively trounced the 959 on the top-end speed tests that many people believe that the car actually had significantly more.
