HSV launches cut-price ClubSport and Maloo

[XUV]

Does anyone know if the 8kw difference is in the tune or the R8 getting the same bi-modal(now standard on R8) as the GTS with 2.5inch mid pipe whereas the previous R8 bi-modal had the 2 1/4 inch mid pipe?

I know 8kw wouldn't be noticeable just asking if anyone knows the answer, would be good to know.

it's a play with numbers , hsv like to include a 7 of some sort , 307 , 317 , 325 , 2 + 5 = 7 ..... lol

I wonder why they went to 325, because wasn't it 297 prior to 307?

So, what they're saying is that they'll produce some new lower-spec cars at a cheaper price, then they'll plug into the ECM and supply the 325kW tune to all of the R8s they've got sitting around currently and cannot sell. Hmm......

Pretty sure the Bi-modal exhaust accounts for the 8 Kw.

Nope. Tune. Bimodel has been optional on the lower cars for years

Well you you learn something every day, I always presumed it was down to the exhaust, in that if operating in "loud" mode, that exhaust gave the KW gain, I can see there may also be tune tweaks also part of the bimodal package, so you are saying if optioned on to lower spec car, they aren't considered to be 325KW, and the boot badge still says 317.

HSV doesn't advertise a power change with the Bi-Model. Thats what I'm saying. The tune is different between GTS and bi-model Clubby. Probably wont be now though with R8 getting 325

I have to disagree with you macca_779.

The 325kw catback is different, and I'm not talking about the rear mufflers. From the cats to the H-pipe it is 63mm (2.5") outside diameter. From there back to the rear flanges it is 60mm. From the rear flanges into the bimodal mufflers it is 57mm (2.25").

For comparison, the catback fitted to other VE V8s is 57mm all the way apart from a short section in the middle that is only 2" and squashed. Optioning the bimodal mufflers on the smaller exhaust doesnt remove the restriction up front, hence the power remained at 317kw.

Ok so a few differences. But still the the bulk of the power difference would be in the tune. There won't be 8kw in that small difference

317 & 325 Same tunes Macca - 325 has fatter front exhaust section

[macca_779]

Then what the hell is the data I've got here. Someone is sending me non stock tunes.

Same OS's ?

[macca_779]

No different years. So thats probably why.

On closer look there is nothing to write home about anyway as far as differences go. Bit of low load economy stuff etc.

So, the 325 R8 will be getting the GTS bi-modal(2.5mid-pipe) not the older R8 bi-modal (2 1/4 mid-pipe) hence, the 8kw increase.

That's what I initially thought, anyway good to know. Thanks for all your replies.
