So an "alternative" to a 4.7, or even a V12V...did anyone else get the email on the Supercharged V8?

500-520bhp.

Bit lumpy at just shy of 20k though...

Maybe something to think about next year smile

does it come with an unlimited mileage 12 month warranty now?

last time I heard it was 3 months and your on your own type thing...sounds a bit risky to me

...think I will wait until theres a few dozen cars out there with a year or 2 mileage on them ...anyone can make a big power kit to last 10 minutes wink

Not sure, but have asked.

I think I'll likely do the same as you too tbh...the current dev car has 1k miles on. That'd be done in a month in my car.

Who is producing this ?

Isnt it the paramount version of the one that RSX in the US developed?

...as per Murph, I can do 1000-2000 miles a month, with the odd trackday thrown in here and there, I want 12 months unlimited mileage/use warranty before parting with £20K for a bolt on supercharger kit .....thats what other conversions offer (in Lotus world anyway)

..some confidence is required in the test and development at that sort of price, especially if spending £20 on a £40K car, you want to know its going to last and not need a new engine in 12 months frown

It was ESX Motorsports that developed it. Supercharged Vantage

But, like you, I'd want a 12-month warranty. And to be able to negotiate a half-price deal as well....

yeah ....its like £6K for a fully warrantied turnkey SC conversion on a 4 pot Elise/Exige from aftermarket (or Lotus themselves)

even if theres double the cylinders/airboxes/manifold etc thats still £12K for a charger, manifold, remap, plugs, injectors maybe

...whats the other £8K ...profit? wink

...got to be some margin in there for a nice warranty backup, thats for sure ........

It is Paramount, but it doesn't look like the one in the pictures on the ESX site - it seems to just make the air intake box bigger with a couple of pullies for good measure.

Apparently it's 2yr warranty on parts, 12mths on labour. BUT I think this is only the bits that are bolted on.

I would guess part of the reason for the cost is the anticipated production run...and presumably the increased number of cylinders adds some complications...but whether that's 3x the price, who knows.

It seems as though a lot of people have been frustrated by Paramount on this forum and on the AMOC forum for several things. I would want to be VERY sure of what I am getting and the actual output of it before I ordered one.

I don't know about AM, but for the Corvette Z06 (or any Vette for that matter), GM has explicitly stated that they will deny warranty on the entire drivetrain (not just the engine) if there is even the whiff of tune in the ECU. You don't even have to bolt on any go fast parts, just alter the fuel/air ratio curves and then if you damage anything you are SOL.

With the price of a V8 or V12 engine in an AM, I think you are crazy to change anything that might void the warranty. Now once the car is out of warranty, things are different.

one of my main concerns would be the standard clutch, they are pretty easy to destroy under normal circumstances, Esx do state they can fit an uprated clutch, but I have not seen any figures on how long to expect the service life of the modified clutch, The extra power is nigh on useless if it can not be consistently delivered to the rear wheels,

ESX kit is a completely different development.

I don't think there's all that much margin in it, even before you start looking at the development costs, which when you're casting manifolds etc., is going to run pretty far into 5 figure sums.

I could be wrong here.......but wasn't the V8V engine taken from the Jag XK?

If so producing a supercharger kit would be simple Jaguar has already done all the hard work! I am assuming the 4.3 was either stroked or bored to get the extra capacity so in general the engine was just the 4.2 block and heads. A twin screw Kenne Bell can be used utilising the Jaguar manifold, pulleys, tensions and idlers all can be supplied by Jag, the biggest prob I can see would be lowering the compression which is done by using 'dished' pistons, these might have to be made.

After a remap 500+ BHP would be easy to achieve and the engines will take the extra power no problem at all.

I might not know the Aston V8V but I know my Jags.

Just a thought....I could be wrong but 20K seems a helluva lot for the upgrade!

one would have thought so ...that there might be an off the shelf Jag manifold/kit avaialble ...would be nice ...as £20K is a bit rich ...like 25% of the cars value new, once youve factored in some new suspensions, pads, exhaust...other bits you will likely want smile

yeah, for sure - if they are having to cast their own manifold, thats just plain silly ...well...I wouldnt bother personally, not with the volume of 4.3 V8V out there in the field, the market is too small to amortise the dev costs surely ...without having such a high price you make your potential market even smaller frown

..unless of course the kit fits the 4.7 too, with a few minor changes

even then, its a tiny volume kit compared to something like a Jackson or Rotrex charger which are found on hundreds of thousands (if not millions) of cars...

I just took a look at the ESX motorsport page for the V8V. http://www.esxmotorsports.com/categories/?id=5015
Take a look, they are now claiming 600hp models.... pretty interesting. Even offer a pumped up clutch.

Also vivid racing has a brembo big brake kit for the V8V. I believe it is 15in front, 14in back.

Just saw they offer a 5l conversion for all V8 Vantage models (4.3 and 4.7).

http://www.esxmotorsports.com/images_products/6171...

A heavy mod, but, from the ad at least, it looks well worked out.
