Spotted on ebay - Red Monaro 6.0 VXR
Discussion
My LS2 VXR seems to give good figures on dynos. I've always been a bit skeptical if I'm honest, I don't want to be suckered in by the slightly egocentric idea that I've "got a good one", and it's always hard to get a decent comparison as I've not made it to a SRR forum day yet.
About the best comparison I've managed was doing a back to back run with a stock 5.7 VXR on a dyno dynamics roller, that at least negated as many variables as possible really. The stock 5.7 VXR made 299rwhp and mine made 388rwhp. That does seem like rather a lot as pub figures would thus be ~470 like this one...
Engine mods wise, just simple stuff, OTRCAI, FAST 102, AAS headers, extremely free flowing cats and a Wortec cat back then some (very basic) mapping by myself with EFI Live.

Straight away you add ORTCAI, Fast 102, and although it mentioned 'zorst, did not necessarily suggest headers and cats.About the best comparison I've managed was doing a back to back run with a stock 5.7 VXR on a dyno dynamics roller, that at least negated as many variables as possible really.

(sounds like a nice set up btw!)

The ad did mention wortec headers when it mentioned the 'zorst, but I agree, just exhaust system and a remap is generally accepted to net around 430bhp, so where he's found the extra 40 who knows!(sounds like a nice set up btw!)
Putting the FAST102 on mine made a noticeable seat of the pants difference before I even mapped it, although you soon get used to it of course
It's not a bad set-up, I've been somewhat lacklustre with the tuning recently, I've removed the MAF and have a wideband fitted now (well, I did, then I killed a sensor, and haven't fitted the replacement yet) so I'm actually finally in a position to get it dialled in nicely and I just haven't got round to it 
Would be great this year to invest some real time getting the fuelling properly sorted out at least
Hello I am new to the forum and just bought the monaro vxr that you are all talking about,the 474bhp,I've looked at the history of the car and as far as I can see it has had a k&n air filter,long tubular headers,cat back switchable wortec exhaust and a remap.not had a good look around the car yet as just got it but will do soon.

Welcome. Forget about the figures, drive it.
Hi, I agree the bhp figure is optimistic I did ask that to be left out the ad but the seller found the dyno sheet.
It has been a good car over the last five or six years and I was genuinely sad to see it go, a couple of weeks before it was sold I was considering putting it back on the road for the summer.
Hope Stazz007 enjoys it as much as I did.
