Remember that Porsche themselve, back in 74 with the 3.0 RS found that an MFI motor with the big overlap "S" cams and the old style tuned exhaust (equivalent to SSI's) needed a 9.8:1 compression to make 230 DIN HP, about 220 SAE net FWHP, I assume local Dynos should be measuring SAE net HP, not DIN.
So they stuck in 10.5:1 and wouldn't you know it? 280 hp.
