E39 M5 - twin supercharged
Discussion
Here are a few pics, vids and info on my 1999 Avus Blue M5.
Got it bone stock in August 2005:

The mod bug bit me soon and here are a few pics taken after
I added the AA CAI, full exhaust and Hamann 19" wheels:


The sound the car made after the exhaust install was very nice

Soon after it got KWv3 coilovers and Brembo BBK:





Added some angelibrights to match the angel eyes to the headlights, here you
can see the difference:

After all these mods I took the car on a trip around Europe:

During this trip I took the car to Nurburgring where I managed
to destroy the diff. While changing my diff the BMW shop also
changed the propshaft and gearbox!!!! (read more about that in the trip thread)
But that was not bad since now the car was ready for what was coming
next....... twin superchargers!!
Had then installed in Sweden and the setup blew the engine on
day 2 after I got it back

After this setback it was decided to get another block and have
it sleeved and build a strong motor





Discrete install
Broke the new engine in on my way to the Ring and the
first run on full blast was actually on the Ring
In hindsight not smart but getting the DSC flashing at
160km/h is interesting.
Fun to drift too:

Just don´t seem to last at all!!!

Last winter I also did some "visual" mods, mostly CF
stuff (hood, splitter, kidneys, diffuser, roof&lip spoiler
and interior trim).





I´m VERY happy with the car and it´s a dream to drive. The power is
ca. 600hp/700Nm


Took it to Germany again this summer - here are 2 video clips, one high speed run
and then a comparison run with a stock M5.

Thanks for the comments guys 

launch and is fast enough
just bought a set of 4 original rear wheels with Toyo RA-1's that I´m going to try next summer.
Should take care of some of the traction and understeer issues
The running costs... yes... crazy!!! But it´s a car that brings a smile to my face everytime
I drive it

Here is another trip report from the BMW drivers training at the Ring this summer:
http://forums.bimmerforums.com/forum/showthread.ph...
I have known to like the older ones better
I realize that some people don´t like the hood
but when you see it in person it looks awesome. It´s also gives the engine bay a much needed
cooling.

It´s been expensive like everything that has to do with the M5.
Why I supercharged??? It was the only way to increase the power substantially without
loosing "streetability". You can get race S62 motors with similar power but you wouldn´t want
them in your street car.
Huge fun? YOU BET!

Outstanding. 
I daren't read this thread again or I'll get crazy ideas.
Yes - beware of the mod bug

Why do I have a sneaking suspicion that you'll be back for even more power?
Top work though
I don´t think I will do any more power adding to this car - it´s difficult enough toTop work though

What a car. I'd have kept the original wheels (have always loved the look of them) but thats just personal preference. Nice subtle mods, huge power & it must be enormous fun to drive if you like sideways, which I do 
The running costs (especially tyres!) must be, er, 'a bit steep' 
The Hamanns are much nicer in person than on pictures - they look awesome. However, I have

I like the mechanical stuff (vroomtastic indeed), but the original wheels, headlights and bonnet looked much nicer.
The headlights are actually the OEM facelift ones and I think you are only the second personI have known to like the older ones better

Do we dare ask how much time, money and effort went into it?
Can I just ask, what possessed you to supercharge it?
Looks like HUGE fun though!
I have a folder full of invoices but I have never added them up and never will Can I just ask, what possessed you to supercharge it?

Like others have said, not keen on the bonnet, but without it you wouldn't get the rest so needs must.
Do you own any other cars?
Nice modding. Always liked the M5. Slightly rarer I find than the M3, appeals to me.

The bonnet is the only part of the visual mods that I wasn´t 100% sure about in the beginning.Do you own any other cars?

However - I am now very happy I got it and you have to see it in person to really appreciate it.
It gives the car a much "meaner" look and tells you this is no ordinary M5

As for other cars I have a 2005 Landcruiser 120GX on 35" tires (good for winter here in Iceland) and
I also have a 1989 E30 M3 for track (the M5 is just too heavy & expensive for track use). The M3
has an 3.2 liter engine & 6spd gearbox from the E36 M3. The M3 is superharged also.
