is there anyone on here supercharged?
Discussion
Not sure about people on here, but I did find myself running against/next to one at Bruntingthorpe, see link below. I believe he said it was circa 600bhp, took off well for sure, but 6 speed and a bit more weight meant it didn't do that well at higher speeds

The concerns previously expressed here, have been about cost in relation to the more usual power increase methods, and uncertainty about higher levels of heat / long-term reliability.
It seems there is a guarantee, although possibly that covers the supercharger, but not the engine.
Seems reasonable on the warranty side, engine could have a pre-existing fault, etc.It seems there is a guarantee, although possibly that covers the supercharger, but not the engine.
Know a few of them are pretty high mileage now without issues.

You are quite right, those pesky V8 motors pop or have faults the owner is limping useage through all the time, don't they just, in fact, V8 engine tales of woe is such a frequent occurrence these days I'm so bored reading about all those stories on the main forum, aren't you?Know a few of them are pretty high mileage now without issues.
Indeed, the mileage folk run to is so super high these days the poor old V8 motors just expire from old age and natural causes, don't they??
Seems GMR are not immune to that natural occurrence either, here is a pic from Jersey Girl (GMR test mule) sporting a different motor to the unit fitted as std. The pic shows a tag on the passenger side cam cover which identifies the motor as a Prodrive racing unit.
Bless them, because when this was pointed out a couple of years back GMR removed the pic below from their webpage gallery. I guess they thought folk might think the racing motor was put in as either a replacement to failure or to make sure a failure of the demo car never occurred by using the stronger updated racing unit. When clearly in reality GMR just presumably wanted the replacement motor to last a lot longer compared to the high mileage the previous pesky V8 motor retired at? meaning the replacement motor wont be littering the over subscribed V8 died of natural causes / old age graveyard.

The marketing on GMR website is about 580.https://www.youtube.com/watch?v=S7bPzKsE7X0
The V8 got the drop on you because he is clutch, you are torque converter auto.
The Vantage is less weight than you and better drag coefficient, gears are by and largely irrelevant at higher speeds, it's all about power and cutting through air at a certain weight meaning your car not winning the weight or aero war simply won on more power - which is how many BHP for your car?
I'm well used to drag racing against the GMR car also, a nat asp GT4 I was running at 450 ish BHP out dragged it too.

Yeesh. Sarcasm overload.
So you like them then?
Sarcasm?? So you like them then?
I prefer a nat asp screamer power delivery over pressure charged any day of week.
In previous life as powertrain development engineer I've delivered 1 supercharger and 1 turbo charger project into production so I'm not anti charging altogether.
Take the supercharger example, Mini Cooper S, the end result was sooo good versus nat asp because base engine was re designed (compression ratio, valve timing etc) to allow the boosted engine to function and deliver the maximum power possible.
I remember the first prototype Cooper S engine, it was pretty much carry over base Cooper with a charger plonked on top - it lasted seconds on the dyno at full throttle, which is what happens when you pressure charge a good performer nat asp engine and change nothing, only way to make it last longer is curtail boost but that means not producing the big BHP numbers.
I know what a V8 Vantage drives like and the power differential between a 410, 430, 475, 525 BHP nat asp engine versions. The key aspect is for each output, is the improvement in the rate of change of engine speed acceleration as a byproduct, so from low speed acceleration to the redline, the more power the engine makes should make significantly faster the engine acceleration rate . I've yet to see a vid where the supposed 600BHP reveals the acceleration rate i would expect and I've yet to see a vid where the driver actually puts car through tough paces, because in reality in either 1st / 2nd or 3rd gear on the straight and in the dry, 600 BHP should lite the rear wheels up and with traction off make the car face southbound on the Northbound Carriageway, but I've only ever seen the car driven by folk who would struggle to drive a greasy glove up a cows arse.
I've access to a 580 BHP V12 Zag - would be interesting to drag race it at Brunters Vs the GMR car. Same weight, same aero, same gearbox

Sort of done that 
Vanquish Zag vs Vanquish S. Weirdly not much differance at all, S looks quicker but I think just a better start, did appear to pull away slightly, only mod I have is decat pipes, not sure if that really adds power or not?! Given previous video it's clear the zag would easily beat the GMR car

Do those cars not have identical powertrains ? I thought when Zag came out, it had uprated power over standard Vanquish it was based on, that was then matched by Vanquish S ?Also, as GT12 and V12 AMR (or V12S with powerpack) have rear de cat to get to same power levels as Vanq S, had assumed Zag & Vanq S both have rear de-cat too ?

That was my understanding also. Mabe the decat pipes do give an extra few hp, could also be down to better launch. Sort off topic really but actually n/a is the way to go! Just sadly not possible in todays world, we will al be driving cars with turbos soon enough then complain when we lsoe turbos for batteries!Also, as GT12 and V12 AMR (or V12S with powerpack) have rear de cat to get to same power levels as Vanq S, had assumed Zag & Vanq S both have rear de-cat too ?
I'd inquired about the GMR supercharger kit because I want to eventually do forced induction on my red Vantage, but was told I'd either have to fly them to the US to do the installation, or ship my car to the UK for them to do it there.
Both options were a dealbreaker so I moved on.
There have been supercharger kits from a couple companies in the US, but not a whole lot has come from them because there just isn't a market for it. The cost to develop a packaged solution is too expensive and uncertain to justify. You end up with either a shop offering a kit that is too expensive for anyone to buy, or a shop that doesn't want to price low enough to bank on a large number of sales due to fear the sales won't happen and they'll lose money.
