Did you notice that all "stock" runs produced results way below Porsche's estimates. Even if the "tuned" runs produced OK results, I belive that
the original quotes were deliberately lower than normal in order to widen the gap between the two figures. Thus giving the impression of a higher gain in HP/TQ.
Example:
The 996TT has 420 HP (normally tested to 418-425)
- here; 409 HP (estimating a 15% driveline loss)
The Cayenne TT has 450 HP (normally tested to +450)
- here; 384 HP (estimating a 15% driveline loss)
The 996 GT3 (mkII) 381 HP (normally tested to 392-400HP)
- here; they only show the tuned 409 HP version!!
my $ 0.2
