So who has the most highly modified CSL?

It's the only way you can get repeatability, along with being able to hold the engine at full load at any rpm increment to check if any improvements have been made.

Also the problem with lots of modern day cars is that they go into limp mode if the ECU detects that the front wheels have any large speed disparity between the rear ones (adversely affecting power figures). And there are very few rolling roads in this country that have a linked system that drives the rollers to make the front wheels rotate at the same speed.

If you're going to use a rolling road, it's best to get friendly with an independent one and stick with using the same place / operator all the time. Otherwise you'll just get conflicting figures from different rolling roads anyway LOL.

I guess you don't know M3 E46 + CSL have dyno mode in the ECU so as you can dyno the car on a rolling road dyno.

Engine dyno is a completely different thing to a rolling road.

Hi Mike

You probably don't remember me, I brought some bits off you about 7 years ago for my Cossie'd Xr4i. Suspension and Shims for the rear beam. Chatted to you at the ring about the lads I was with in there CSL's, only saw you on track once that weekend, you were on the side waiting to get towed. lol drive shaft I think?

Anyway, I have gone down the Shrick Cams, Live Map, Standard back box, race cats, as well as ap's, intax, half cage etc. the work was done by a very repected german tuner at the ring with a lot of csl tuning and m3 experience. anyway on the dyno print out he gave me it made 387bhp.

I have just this week ran in a new standard engine, as he put the cams in a none standard position and ended up burning out the solenoids and the piston hit the vavles, among other school boy error the old engine was pretty much scrap.

The way this new motor feels, total seal piston rings, multi layer head gasket. I would say its just as quick after spending the day on track at siverstone today.

I honestly wouldn't bother to much, but if you want to speak to someone who has a 415bhp engine, ring Will at Geoff Steele Racing, he'll build you one. Top Bloke, along with him and Mr Vanos my cars not being touched by anyone else.

Good to see you Escos is still going strong, hopefully see you on track in you CSl this year.

Cheers

Hi Ando,
I remember the woes I was having that year with standard drive shafts, which kept popping out of the CV joints due to the camber we were trying to achieve on the adjustable TCAs. Took some custom GKN drive shafts and some adjustable top mounts in the end before it was finally sorted.

Sounds like you have a really well sorted Cecil, although if you can't trust a top German tuner to get it right, who can you trust LOL.

The more I'm reading, the more I'm being inclined to leave the engine well alone other than for basic optimisation mods.

I'll certainly be going to Germany with the CSL, so perhaps we can meet up again and talk BMWs this time .

Geoff Steele Racing, haven't heard that name since I last purchased one of their air boxes' for my E36 ///M. Also, Wayne Schofield, top bloke with some serious tuning skills.

I think your right about not doing much to it.

Hopefully catch up at the ring, be good to chat shit about cars!! lol

I know one thing though, after all the crap I had with garages in Germany, I'll never be leaving it out there to get any work done again, I'll go get it on a trailer and bring it back to people I trust.

Cheers

Ah ha. Trust me, best thing you've written in this thread so far. Good decision.

I on the other hand would like to see Mike get it stripped and modded and eeeeek out another 25bhp......but I fear it might cost him tens of £000s.

I'd love to see a reliable road drivable 400bhp n/a s54 but (with all due respect to anybody here who has denied their cSL above 270bhp) I fear it would be impossible.

Stripping a CSL out beyond the what BMW have is sacrilege IMO . All I will be doing is making some additional carbon detailing (all proper pre-preg stuff). I've already bought a Vorsteiner front splitter to get some increased front end grip, but that will be as far as it goes with the external mods - you can't improve on perfection .
