Supercharged CSL
Discussion
Does anyone have any experience with Supercharging an E46 CSL?
There is a company called Simpson Motorsport who do various ESS kits, starting from 450bhp up to a 550bhp.
I have often heard that supercharging a car hasnt delivered the desired result, and that the figures do not reflect the cars performance.
I am thinking of a replacement for my modded Cayman S (340BHP/300Lb/ft)
I have only ever heard praise about the CSL
Any info would be great

My first proper experience of a CSL was last Friday - ca.100miles of cross country bliss...cracking car, but seriously, something you don't want to lose is the induction noise....just fantastic, but would be lost with SC kit...360hp is a perfect match for the chassis and on Mich PS2's, a very biddable car in all weathers (including biblical downpours) where the power is so exploitable, far more so than in my GT3 (I dont mind admitting, if following, I wouldn't have seen which way the CSL went in anything other than dry conditions)
Simpsons do it and so do CA Automotive. Ive seen a few at Simpsons and the latest ESS kits seem pretty good but with anything other than 50+ bhp the problem seems getting the power down onto the road.
I wouldnt mod a CSL as you have to make so many changes anyway to the suspension and running gear you might as well start with an M3, but chances are you will regret it and might as well buy a CSL
THere was a supercharged E46 M3 at Bedford Autodrome on Monday this week, drove past it on track a few times!

as one other has said, you lose the fantastic induction noise by supercharging - on the upside, selling the carbon airbox would go a long way towards paying for the conversion!
Brakes and suspension are down to what you want the car for! Road use, probably no point. If you want to track it then I think you will need to do the mods.

Thanks guys,
I am getting the CSL itch, It needs to be itched. Most have uprated suspension and brakes.. are those essentials?
For tracking, the brakes might be useful. I am getting the CSL itch, It needs to be itched. Most have uprated suspension and brakes.. are those essentials?
For very serious tracking, the suspension possibly too. But it would have to be very, very serious tracking, IMHO.
On the road the car is fine as it is
for track unless you are a pro driver you will need a BBK but suspension only if you really need that extra 2% or something to fiddle with
one of the biggest benefits of a/m suspension I have found is that it greatly improves wear on the Cup Tyres with less roll

What you really need is a BBK Alcon kit.. like the one i have for sale.. in the classifieds for track unless you are a pro driver you will need a BBK but suspension only if you really need that extra 2% or something to fiddle with

For track work I would say brakes and supsension mods are essential, these cars need 2.5 min but preferably 3 degrees front neg per corner, or they destroy front tyres...
I looked into a blower for mine, before doing the Schrick cams, I based that decision on the Simpson car breaking the gearbox the day i was due to test it..! and talking to other guys, who loved the power.. but 50-80 miles on a tank of fuel on track with the bigger injectors put me off, 150 miles a tank on the road.. so i was told..
Its not about economy of course.. but it would just wind me up going to Tescos every other day for fuel..!

To the OP, I hope this doesn't come across as condescending (it's not meant to)
Buy yourself a CSL, drive it for 20K road miles in the first year (as I did) and you'll come to realise there's nothing to be done except put fuel in it, service it and enjoy driving it (and pay for the warranty) Mine's done two massive Eurohoons and proved to be peerless for the job I wanted it for.
It REALLY is THAT simple
My car is totally standard apart from AP six pots on the front and AP 4 pots on the rear (and a rear axle tightening kit fitted by Simpsons)
Forget any bar the above mods for ROAD use, as they're (IMO) totally uneccesary. That includes noisy/ lightweight exhausts, spring/damper upgrades AND supercharger kits . . . .
If you want to track it then the situation differs.
HTH

totally agree for road useIf you want to track it then the situation differs.

apart from he will need RTAb and Turner limiter kit

Good information here guys, whats a RTAB ???
Looking to buy Jan or Feb and get on a few track days. CSL is creeping to the top of my list for age vs value vs potential to go wrong.
Rear Trailing Arm BushLooking to buy Jan or Feb and get on a few track days. CSL is creeping to the top of my list for age vs value vs potential to go wrong.
A known weak point, lots of views as to how to "rectify" the issue. I went for new standard bushes and the Turner Motorsport rear axle tightening kit
http://www.turnermotorsport.com/html/detail.asp?PR...
(Basically a pair of alloy shims that go either side of the standard bush and remove a lot of its compliance whilst retaining its ability to articulate in two planes as the trailing arm/suspension moves through its arc)
This one mod alone makes the rear of the car much more planted and controllable as it removes a lot of the "rear steer" the standard bushes allow when past their best.
