VZ SS Versus VZ Calais

[Rhin0o8]

Has anyone got a genuine explanation for the difference in power output on the SS 5.7 Litre V8 compared to the VZ Calais 5.7 Litre V8 ??

VZ Commodore SS
5.7 L 250 kW (340 PS; 335 hp) LS1 V8 (until 31/12/05, then 6.0 L 260 kW (354 PS; 349 hp) L76 V8 from 1/1/06)

VZ Calais
3.6 L 190 kW (258 PS; 255 hp) Alloytec V6 (option of 5.7 L 235 kW (320 PS; 315 hp ) LS1 V8 until 31/12/05, then 260 kW (349 hp) 6.0 L L76 V8 from 1/1/06)

the ss ls1 is classified as the high output ls1.. it would just be a tune

yeah it just to make the SS better then the calais.. cant have the calais making the same power as a SS

Holden VZ Commodore - Wikipedia, the free encyclopedia
is where i originally got the info.. and we all know what wiki is like. lol

this website below gives a 2nd confirmation

VZ Commodore Specifications at My Automotive Forum

and this link below tells us more what each engine has added for performance gains
as said above the SS had a "high-output" engine. ( a performance Dual exhaust gives the gains )
keep reading and a High Performance Split Dual Exhaust is added to get 260kw. ( same as a 6.2 litre ?) interesting

I wouldn't really trust that site, There's no mention of the l98 in the VZ's, lots of technical data is missing, and it's well... just a bit dodgy sounding.

grabbed from the holden site

both ss and calais are running the same power.....
