has anyone done this im really interested in getting it done, what sorta money would it be

[Kevin Wood]

How long's a piece of string? 

You've obviously got mechanical issues with driving the supercharger and finding somewhere to fit it.

Sizing the supercharger to suit the engine and the performance you expect is another issue.

That aside, the 3.0 engine is 10.7:1 compression as it is, so quite high. You wouldn't be able to use much boost before you were looking to reduce the compression.

Then you've got engine management issues. You would only get a very modest power increase on the standard ECU before you're looking at changing that for something mappable.

V6 Engines also have cooling issues above about 250 BHP which require changes to the coolant plumbing.

It could be done, and would be a nice project, but don't let anyone tell you it's not a bolt-on accessory.

just stumbled across his and was looking at trying to do something similar but wit a turbo instead will keep watching for updates and didn't know the ecu wasn't mappable.

[Grrrrrr]

Have a look on UTube. Pretty certain I saw a supercharged conversion in Germany on there a few years ago.

Sounded impressive!

I have wanted to do this for some time but not sure how to go about it...Looked into some years ago and courtney sport did one for the 3.0 v6 but when i rang them they said it was made for the police in irland and it was then put on the back burner but they had also mislaid the spec sheet that had put together. 
  Have seen one for sale years ago in the back of total vaux which was being sold off a vectra but i did not have the two grand i think it was at the time. .
Have also seen one for sale on germane e-bay last year i think it was now but again cost to much.
Have a look at this one anywayhttp://www.youtube.com/watch?v=ViGhqPlbTw0&feature=related

A friend of mine has been trying to supercharge his V6 for the last year in a 2.5, almost given up now with all the problems, has cost him over £2k and STILL not right. Will run, but doesn't run at any real speed, and over fuels, and coughs on tickover. He says he will never try it again, IF he manages to get it right. NOS is so much cheaper and better with a lot more advantages, have done it to my own cars several times, and its reliable, relatively cheap, and transferrable from car to car!!

Gotta be a good performance thing, because its "standard" until you push the button...............

supercharging is relatively easy compared to many mods, but I suspect that my idea of relatively easy is a bit different from your mate's

The proviso - absolutely all modifications should be done to at least the same engineering standard as the vehicle was originally produced to.

ok, so you'd be wanting to source and bolt on a supercharger, to engineer an intercooler of some type, probably to drop the compression ratio, prove that the fuel supply is adequate, replace the fuel injection with a mappable system - don't even think about using the standard Motronic

costs if you do it yourself :-

fuel injection £750
supercharger £150
drive system £300
intercooler £500
pistons / engine work £750
fuel system £200

probably no change out of £3000

[Kevin Wood]

Agreed.

This is how I would spend the first £18.99 of that budget:

I'd read it cover to cover, decide exactly what spec. I was aiming for and the specifications of every component required to meet it before spending a penny more.

The key to success is to engineer the whole solution to work properly. The key to failure is to bolt a load of random bits off ebay together and hope the OEM engine management copes with it.

I really couldn't have put that better myself.
