Supercharger in CSL - Bottom Line
Discussion
So, the supercharger will make the CSL lots faster, and the chassis can handle the power well.
However, my opinion is if you want to do this, you should start with a normal M3, and not butcher a CSL.
The savings you make in buying a comparable (age/mile) M3, to a CSL could be spend on stripping, caging, and fitting the carbon roof and the ducktail bootlid.
you wouldn't have the airbox noise anyway...

Bottom and top line .... NO
True with a S/C your straightline speed past a 100 is alot quicker than a NA mildy tuned CSL.
However even with Racelogic T/C it is hard to launch properly, i always launched harder than a S/C CSL , even with worn rear boots and bent trailing arms and bushes. Put L/C into it and i'd leve the S/C car by a lentgh or two, only past a 100 will the S/C come stomping past.
Also there is no C/F airbox noise for me that is a major downer. True the supercharger, whines/whistles and pops but nothing close to that air being gargalled by the CF box.
Finally the whole point of the CSl is the cornering, not dragging or straightline speed. True the S/C might not make it that unstable in cornering, but i doubt it would remain as balanced as it was without S/C.
Yes the LOaded CSL is supercharged but the guy has thrown limitless money at that car, must be about the same cost as a Carrera GT, well i think so and was it driven by Hans ?? !!!
DRHilder put it this way, would you S/C your GT3 RS ??
I no i wouldn't.
Godluck with whatever you decide.
If you do want a quick CSL, get one without, AC/Aircon/Xenons.

I reckon yes you could drag out 30 - 40 bhp but it would not be cheap.
Full exhaust system Supersprint including manifold 4.5k +
Crazy Intake in front on the C/F airbok where the kidneys are ( like what HoulbT is getting ) 1.5K
Shrick high lift cams 2k
live mapping 1k + ?
Head and internal work ??
displacement increase to 3.4 ( as in Kellners , i can't find no information on this subject, only car that had this in England as far as i am aware got torched
) 3k ?
Cheap way out NoS ? ?
Dr you ever consider a E36 3.2 and supercharging that and stripping weight of the thing ? ? or just slot a e39 M5 V8 in the E46 ?

Ouch - you can see why SC seems an attractive option in the face of these costs. And all to keep pace with GT3's et al on the straights!

Might be worth speaking to Simpson Motorsport as they have tuned and supercharged CSL's. Either way its lots of money and often they take out the CSL engine and start with a standard M3 lump which, as mentioned above, makes you wonder if you are better off with a standard M3 as a base.
Think V8 corvette is the way to go!

There was a Z3M Roadster at Santa Pod with an LS3 engine in it.
And it was spotlessless fitted as well after chatting to the guy. He pulled a 10.5 sec run first time out but could not manage that again all day. I saw the timing slip so I know he was being honest. Beat my lowly 12.4!Corner speed is not a function of your engine power, but amongst many other things, of how much speed you shed before you turn in and how much you floor the pedal once you start aiming for the apex, add your suspension set up, tyre compound etc and it gets complicated to say the least...
Just as an example, most of the regulars here know Fabian with the white and "ropey" looking Swiss E30 M3 at the Ring. Easily one of the fastest cars out there bar the Edo and a few other nutters, and it should not be - after all every hardcore M3 enthusiast will wax lyrical about the balance of the car as a function of its sweet 4-pot. Fabian has a ex-works M88 engine with 450Bhp instead. Is the car bad to drive? I don't think so, otherwise explain the low 7:20s he seems to be getting on a regular basis...

I recall reading an edition of Performance Tuner which tested some Supercharged M3's including a CSL against a standard CSL. The review stated the difference was small. Maybe just that particular make or that vendor doing something wrong?
It most probably is if you're looking at the 0-60 times,I bet once you're passed 100 it's a different storyGassing Station | CSL | Top of Page | What's New | My Stuff
