So who has the most highly modified CSL?

[Mike RT4]

Please point me in their direction, as I'd like to have a chat with them about what they have done and what they think to how it has improved the car .

Alternatively if there is a build thread, then please link me up .

To put your mind at ease, I forgot to say, I know Bealo and rstoughy (however, please don't hold that against me ).

Mike, thats almost impossible to do

Road going version i presume?

Given the current state of my car I'm not sure if it is really a CSL any more, it has a CSL vin and roof panel if that helps?

If your not familiar you should check out: 'Loaded' http://loaded.se/the-car/
A CSL which is in a continuous state of flux and metamorphoses, what's done today will be changed tomorrow. Objective to better his 'Ring' lap time of 7.22 (standard spec 7.50):thumbs:

[Mike RT4]

I'm talking UK cars and performance mods for track day / 'ring use (and driving to and from these events).

I already have a dedicated track car and an E90 M3, I want something that sits between the two .

However, a standard CSL is just painfully slow, so wanted to know how far you could go without forced induction (and not theoretically or anecdotal comments, but real world experience of the kind of mods listed by the likes of Thorney et al).

most stop with 9-9.5" rims all round, Cups, Suspension coilovers and AP brakes. Do this and then worry about your driving. I can honestly say i have improved my car by 2 secs a lap and me by 6 secs a lap since starting.

If you stick a charger on it you will regret it

AND HOW DARE YOU SAY THEY ARE PAINFULLY SLOW:moan::-D

[Mike RT4]

As stated, I'm also not interest in forced induction, but was wanting to speak to someone who had gone down the engine tuning route (cams, porting, headers and full system combined with a remap).

As with any M car being used on track, upgrading the brakes is a given and suspension and geometry changes I know gives good improvements.

My own track car is bored and stroked (but with reduced compression height pistons and longer rods, so that it retains the OE rod angle and loses nothing in torque or rev range), but you CSL boys seem to be scared of anything like this :gayfight: . Surely someone has gone nuts on the engine tuning?

Have plenty of customers that have proper engines, for road car I am not sure I'd bother.

Define a "proper" engine?

20k euro and 20 hour warranty.

Pm DuncanR.....

He's ok once you know him :thumbs:

[Mike RT4]

That doesn't sound very proper to me. The cost doesn't seem out of the way, but the life expectancy does. What on earth do you do to them to make them so fragile? Surely with the correct parts (crank, rods, pistons), they can produce the power for longer? We can get 800bhp out of a 2.2 litre for £25k and warrant it for longer :P.

Once more the S54 engine tuning saga

The P54 engine by BMW Motorsport (~80k euro just for the engine) produces 390-400hp and is the racing version of the S54.
The reliability of course is the one of a racing engine.
I don't understand how someone can match these numbers without drastic changes and relevant cost of course (Nathan said 20k euro for non-BMW upgrade I suppose ?).

My personal opinion is that the last thing a road/track CSL needs is engine work.

[northernjim]

I think the essence of a csl is not the power of the engine, but its balance and grip, so if your heart is set on modifying a csl- then I think best plan would be to remove as much weight, as well as a few choice mods....


but seeing as your track car is the crazy escort, you could get a stroker kit for your/another e90 ~530bhp is doable I think? That is a car I would like to see on track:notworthy:
