- 2011 HSV GTS
Just remember that holden quotes on a different scheme to HSV on power figures can't remember the details but if the same a 304 holden would be 317 I recon. A 340 HSV would be about 325 in holden money.
It is not that much of a difference, the 304 kw is 309 kw using HSV's method. The extra 8 kw to get it to 317 kw comes from the HSV headers. 325 kw is a result of 2.5 mid pipe and bi-modal mufflers. 340 kw comes from revised headers and bi modal air intake.
