Done a bit of searching, and found that the limit is 95 dB in most US states. As for Australia, we have ADR 83/00, and according to the RTA website, new standards have come in for vehicles manufactured after 01/01/2005... with 90 dB for cars and 94 dB for motorcycle. Pre Jan 1 05 cars were limited to 93 dB. I have heard, in person, a Corvette C5 Z06 with the LS6 GenIII, and an SVT Lightning with the S/C 5.4, both stock, and they were both.. well, very quiet, especially compared with some of HSV's and FPV's finest. Done a bit of searching, the C5 Z06 Corvette, 2001 model (the 385hp version), made 94 dB at 100% throttle (1 dB over the previous Australian limit). During normal driving, it produced 79 dB, and light throttle cruising, 59 dB. The new Z06 apparantley produces 90 dB at full throttle. US regulations are getting lower, with California moving to introduce a max 90 dB limit on all new vehicles, and California is the strictest state in the US, so all manufacturers have to make sure their vehicles are California compliant above all else. Australia and the USA are not as far apart as you'd have us believe. Again, there's no reason (aside from the apparant 300kW local limit, and media scare fears) that HSV could not quite easily import the LS7. They have the drivelines for it (the new 6L80E they're getting, and the T56), it fits the cars (identical size to LS2), and they can quite easily make it noise compliant (they're importing an engine, after all, the exhaust system has to be tailored to suit Commodore... why do you think our LS2 outputs 297kW 530Nm and not 299kW 542Nm like the Corvette C6 - its the exact same engine).

And btw, maybe this article could shed some light on the respective merits of both both performance cars...

I never said HSV couldn't use the engine, just that it wasn't a case of bolting it in and off they go like you stated earlier. |
