** Evosport CLK63 Black Series Project **

[LZH]

Brad - Thx man. Sounds about like I thought it would. Really opened it up so much so that you can really hear the motor now - I dig it, alot. Question though....how do you avert CEL and other associated probs with no cats ? Are you just looping 02 sensors? Any plans to stake the stock cans and rework the insides or just remove baffeling ? Thx -

This thread just made me start sweating.

This is incredible stuff. You should go 315 in the rear 285 in front 305 is ok but you can easily get a 315 on an 11 inch rim, may as well go ballz to the wall, car will plant real nicely. i have a 305 cup on my 10" and its fine but if I had an 11" my goodness a 315 4 sure.

The roll cage is amazing , the wheels are a dream, the car is going to really move out with the weight reduction.

Did you guys weigh the car? what will the weight savings be or did the addition of the roll cage and headers etc mitigate the gains of the wheel's?

Jim, I will be more than happy to escort you around Hollywood if you wanna come down. I will check and see if anything is open so we can run FEB 27?

Great JOB EVOSPORT!!!!

I can't tell if it sounds any different by the video.

I don't see the new Dymags either.

It's a premature emasculation...

If you cannot hear any difference, you need better speakers on your PC!

I think anyone near Huntington Beach yesterday HEARD the difference!

Oh yea, we are adding resonators now to deal with the little off throttle rasp. You can HEAR the motor for sure. It sounds really amazing. If anyone has been to an F1 race, it now sounds like the MBZ safety cars now! So cool!

CEL - good engineering and a good software partner!

Stock mufflers - we could, but I think everything would be better served with a different muffler. Even the OE tips could be re-used. We will see once the resonators get on.

Thanks for the nice words.

There is no way to lower the car to a proper ride height and fit those tire sizes in a DOT-R tire (remember for those not used to DOT-R, DOT-R tires are wider the standard street tires. So a 305 DOT-R will really be about the same as a standard 315).

We did a lot of test fitting and with the clearances that we have there is not going to be any way to go 285 front and 315 rear. At stock ride height yes, but there is much to be gained in handling by dropping the roll center, and that is a bigger gain then a bit more tire.

Thanks again for the great praise!

thanks

Juicee63; I may take you up on that offer. I am coming out there with one of my best friends, we are going to party it up Hollywood style for a couple nights before driving to Vegas. We have a very good friend that is Director of Legal Affairs for Playboy, so he usually has some insane hook-ups.

As for the tires, I don't think 315's will fit. Evosport and an I believe engineer or rep from Dymag took all kinds of measurments on the car trying to maximize my contact patch and 305 was the largest they said I could go. Keep in mind they lowered the ride height adjustment and we are running much shorter springs than stock, I think I am rolling at least a inch lower than stock. This car will be driven and driven hard, I can't afford to have ANY tire clearence issues. I do believe they are trying to go 285 up front, it's going to be close, have not heard a verdict on that yet.

I guess Brad answered those same question while I was typing my last post.

I will PM you so you can call maybe we can grab a drink !

Man I am so Jealous, sure would be awesome if the 1000 hp SL and the 750 hp SL were done around the same time,

I see about the tires, 305 will be plenty , cannot wait to see this, I may just take a cruise down and make sure its ok, LOL

I'm over here in torrance and i heard it. LOL Now post some Real vids and forget the teaser stuff.

[otoupalik]

Some updates.

Exhaust:
- We did add our high performance resonators, the rasp and harshness is gone. it sounds amazing!

Dyno:
- We have finished the first night/round of tuning. Pretty happy with the results so far! +56 RWHP and +47 RWT for the header, exhaust and software (of course done with our tuning partner Powerchip)!


Here is a quick vid on the rollers:


Aero:
We have completed the front and the rear bits (with big thanks to our aero partner Vorsteiner who came through once again by accomplishing the impossible with far less time then reasonable):




* You can click on the images for more pics *





* You can click on the images for more pics *

The Carbon weave on the front and rear matches OE almost perfect. These are pre-clear coat, which is happening now. It is really hard to see the CF on the rear due to the lighting, but it is full CF.

More to come........

Thanks
Brad

[spr]

Very impressive results and nice front lip. I think the rear is a bit much however-

[LZH]

YIKES !!!! That sound is pretty sick man. Love the front air dam, but I also feel the rear tail is a bit much but looks trick nonetheless. Brad, wat is the lead time on that front air dam and headers ? I think I might next in line !!!

[ET550]

I think your math (or typing) is faulty on the horsepower increase. It looks to be a 56 RWHP increase, not 66.

[otoupalik]

fixed.

Believe me, I'm not a fan of big wings. Aero was one of the first discussions I had with the guys at Evosport, and I told them I absolutely hate big wings, but this car needs downforce. Why do you think they put that big wing on the DTM car? The stock lip is a joke! This was done 100% for function. I'm no aero engineer, but I don't think I could do one without the other (front vs back). I had the choice of the Europe only M-B OEM (DTM style) wing or this one. In my opinion this is far more attractive and unique, while still maintaining a close to factory look, so I went this route. Besides, I actually like it now that I see it and it turned out better than expected.

I totally agree, and the DTM wing would be a bit much for the street. But, how was this Evosport wing developed ?? Was a windtunnel used to see exactly how it will react at speed or did you guys just make it bigger than the factory wing ??

[otoupalik]

lol - no windtunnel used. But, realize we run one of the most successful BMW racing programs around. We have extensive real world and track testing with many different aero mods.

That aside, it is pretty simple. Bigger lip, bigger splitter = more downforce. We will not now the aero balance till it is on track, and that will vary depending on each track.

Net/net - this is a functional and stylish update.

thanks
Brad

Agreed...however, this says alot

Point I'm making is that AMG has a pretty successful racing program, too. So much so that they know exactly how the smallest aero change will affect the car at any given speed....Saying bigger lip, bigger splitter=more downforce is true, yet hardly technical. Don't get me wrong, I think the car looks stunning....just saying that there are alot of unknowns with the changes that have been made aerodynamically and this car is going to be quite a handfull with the FIXED (read not adjustable) aero you guys have added. The one thing I love about the Black Series is how neutral the handling is. With the aero changes you have made, well, you really won't know how the handling has changed until it actually happens....in other words, the changes have yet to be proven in the real world as AMG did when they developed the car.

Lastly, to really get this thing dialed in it's going to require a professional driver on a closed course and plenty of trackside support, lots of datalogging, spring changes, alignment changes, swaybars, compression and rebound damping adjustments, etc...

[Simon @ evosport]

More pictures of the Aero Package. The carbon is exact same weave as the factory carbon. And the pictures really don't do these items justice. We are very excited and happy with the results and Vorsteiner did an amazing job with these items...

[BMWEATR]

rear wing isn't to bad looking, looks better than stock. and since this car will be tracked it is totally necessary(sp?) any way great job evo sport!! this car rocks and i wish I had a chance to put it to the test on the track!!

[MACHC5]

I think I like the Carbon Bits that are added...

Simon, is the front splitter an appliqué... over top of the factory splitter.?

I'd love to add HP but in N.J. at MV inspection time they plug into the ECU's OB wan port, young Jedi.

They would slap a Red Fail sticker right after hooking up to look for any tampering and ECU codes.

HUH ???? Are you telling me the NJ dept of motor vehicles has diagonstic equipment and the associated techs with enough knowledge to see if your stock ECU has been retuned ??? I find that very hard to believe. Most likely what they are doing is looking at OBD II data for emissions and any related codes being thrown...

[TECHNICIAN]

sounds insane

[SteveL]

I very much doubt that. The fuel curves and timing are modified but that would be undetectable by any equipment they have. It is still the stock ECU. They would need to have reference fuel curves and compare which there is no way the will do.

no way than can tell. BUT! they will sure notice the exhaust issues!!!!!

[LZH]

One other thing....as low as this car is going to be....and it's pretty damn low in stock form. Jcart has said it will be driven on the road mostly, that front splitter is going to get beat up badly without some sort of heavy duty ABS protector under it similar to whats available on the F430.

I found out from my 2005 EVO what they can tell about the stock ECU's.

There is a check sum that the stock ECU's have and when it's modified the check sum changes.

The end result is they don't have to know what changed... they just know it was changed from a listed sum.
