So who has the most highly modified CSL?

[Mike RT4]

Interesting thread.

Mike, did you consider putting the E90 V8 in? Sacrilege to many/most but I always thought that would be a nice way to up the power.

As I understand it the V8 is alloy block, so lighter, and a perhaps a bit shorter being a V (I'd like evidence of that if anybody has figure - don't want to spread bullshit )

to me that sounds like you'd be getting the comfortable road use, more power and potentially better handling. I'm sure there are aftermarket ways to get the induction noise back too.

I keep thinking about it on a regular basis, but keep discounting it on cost, complexity and noise reasons LOL. You have two choices - aftermarket ECU and dash system or transplanting the E9* item, complete with loom etc.

Because I already have a track car to this kind of level and because of how I want to use the CSL, I don't fancy the aftermarket route. However, the logistics of using OE stuff is a little daunting. Combined with the fact that I don't like DCT boxes (I had previously hankered after a GTR, but the driving experience and the noise it made changing gear left me cold, and so dissappointingly I knew it wasn't for me), which would leave using the manual box - but for me this moves away from what the CSL is about. Then we move on to the aforementioned "noise" issue:- we have an E90 M3 in the family, and although I like the noise it makes, I LOVE the sound of the straight six and the "buzz saw" induction of the CSL when the flap opens :smt055.

I'm still trying to find someone who can PROPERLY live map the OE ECU, as then I can explore the options I have in mind .

I did toy with the idea of putting manual box in the CSL too...

Well, I think the full E90 conversion has merit but if it's not for you that's fair enough.

thorney's suggests they tweak their maps on the dyno but it doesn't seem like a proper live mapping (http://www.thorneymotorsport.co.uk/t...sl-power.shtml)

Evolve do a custom mapping on their stage 3 package which suggests the ability to tweak the parameters as above but don't state live mapping specifically (http://www.evolveautomotive.com/engi...-packages_881/)

I'd be interested to know what else you come up with - my father has a dyno and does superchips and a bit of club motorsport standalone stuff but doesn't have kit for the OEM remaps live or otherwise - would like to find some software for this that I could have a play with to make a good map for the relatively cheap 102 octane fuel we can get in Germany. Something to make visiting the family at christmas a bit more interesting.

Have any of you CSL owners gotten a tune from SAL @ EVOLVE? If not I highly recommend that.

Not sure if this has already been posted, not a csl but never seen an m3 with this much power before, insane...

Just read the this 22 page post nothing better to do, “brilliant “ did anybody ever really improve on the csl engine after this post back in 2013. ??? Or is this one better left in the past:whistle:

[CSLManual]

I highly doubt anyone is anywhere near as brave as they were in 2013 to modify a CSL in 2018 unfortunately, so probably not a lot has changed since then.

Great read for me as I only heard of / joined csl reg a couple years back,, csl was just a car to me , bought it back in 2004 just because I liked the look of it , never give it a thought they were bought for trackday cars ,, was just a good looking car for the time .. just couldn’t part with the thing now regardless of value, ..But a real interesting read for me, as We’ve still got this striped csl motor laying about,, “”must get back to it””. Hopefully there’s some more interesting information out regarding reviving this old post:thumbs::thumbs:

hello

I understand that Butler motorsport can get decent power, close to P54 levels.
I am tempted to take mine for a refresh + modification if I don't find a P54 engine.
So there will be news

I have been told this too. But I have also been told that such an engine requires regular rebuilds to stay healthy.

I went away from forced induction completely and the Cossie was sold three years ago.

As you may be aware, I ended up with a reasonably modified CSL - APs, H&R coilovers, full Supersprint system from the headers back (with all the standard parts tucked safely away) and I love it too bits. The engine is completely standard (I soon realised after much research that it was already on the limit of tuning without a huge amount of money thrown at it, which would not give significantly noticeable returns on a VFM basis (the only thing I miss about an FI car) and would reduce the reliability.

It's not fast, but has perfect poise and balance (a scalpel to the Escort's machete) and the wail of the straight six is one of the best sounding engines in the world (IMO).

The CSL also got me back into NA cars - so much so, that I bought another car with a great engine (the world renowned F20C). A bit of a hairdresser mobile, but revving to 9000rpm never gets tiring - and with double A-arms, the chassis is a peach.

I do miss the Cossie, as it was the always the underdog and surprised LOTS of people, my favourite being the owner of the 750bhp GTR at a charity day.

Linky not working.

Thanks in advance
