Turbo or Supercharger for E34 M-5?

[91m5]

Does anyone know who can boost me? I`ve seen them for 92 on..but no 91?
I found some company out of Germany called,Lenz Motorenchnik that makes a sick setup,twin Superchargers!! But I cant get anyone.?.
I`ve got 2 faster rides,but none as nice as my M-5.
My Evo gets to much attention,( from the police)and the M-5 just gets respect!I`m hooked on BMW, just need a boost.

Seems like a nice car. How about some pictures since this is your first post?

from what i understand it's a reaaaal bitch to blow an s38 engine, as it's so highly tuned from the factory.

Don't bother - its such a pain in the ass to put a roots blower on a car not designed for it and its kind of a cheap blower to go with - yeah the parts are cheap, but the rotors wear out relatively soon and lets be honest, are you going to be happy with it?

My background info:

I used to have an Alpina supercharger on my E34 525, I repullied it and had it around 9 psi. It was fun, but after about 6 months I was bored - I now have a huge holset turbo on my car that I just got done driving - - and I really cannot recommend anything else! The problem with a CF blower is that all the boost up REAL REAL high. A roots blower may bring the air down a little lower, but if you're serious about torque the only REAL answer is a twinscrew which simply does not exist for the S38.

If you are serious about turboing an E34 M5, and only about 0.004% ever are, you need to go to http://pure-pf.com/ the owners name is Andreas and he has put seveal S38s into the 8 - 9 second range. He is also the one responsible for VS Motor E36 S38B36 twin turbo that ran I believe a 7.7

Either way, BMW designed the S38 as a high output L6, so it's high compression. You need to do internals or a thick headgasket on it to bring the compression down to at least 9.0:1. This sort of work is not cheap, especially since your parts will be from Sweden and this is an S38.
