Thanks for the reply, much appreciated

Acid at MSL UK has the car and is working endlessly to rectify the issues and he is dealing with all correspondance due to me being Offshore North Sea at present
Mine is the only CLS with a Weistec 3.0l Blower in the UK so you'll know the one.

Current mods are;

Weistec 3.0l Supercharger, Kleeman Headers, 650cc Injectors, 170mm Weistec crank Pulley, 3" Exhaust with X-Pipe, Weistec split cooling ice Tank, Water/Meth system, EC Heat Exchanger, Quaife LSD, TCU mapped, Rear Rubber 305/25/19 Eagle F1 Asymmetric, Front rubber 255/35/19 Dunlop Sport RT Maxx and a Partridge in a Pear tree
702bhp & 691lb/ft torque

Weistec

We will be sure to discuss this with MSL. As a quick reply to what it might be, we have seen increased temps due to restrictive exhaust systems. Not to mention high boost readings as well from this. We will get exact data to further understand if this is the case. Please be sure to keep in contact with MSL and we will correspond this way. Thanks!

No worries, thanks

As a note, the exhaust system fitted was free flowing 3" cat/res delete straight from headers to back boxes so can't imagine that would be the cause but as you said, MSL will look into all the data and get back to you

Thanks and take care

what size and where are your method nozzles placed? you should not see that high iat with method bro.

heres a quick 40-100 pull and 5th gear acceleration in my stage 2 c63.

Looking for feedback as I am considering a C63 for a possible Weistec SC project.

Should I be concerned about a high miles car?
Transmission?
Real world performance on stage I
Stage II

Thanks

I dont think mileage is really an issue as long as it has been properly maintained. If its 2011 or older make sure it's got the updated headbolts or install studs as even more stress will be exerted on them. Stage 1 and 2 are basically the same with a different pulley and headers. Stage 2 is trickier for emissions counties like austin so becareful. I'd recommened the valve body at minimum or fully built trans for any of the non mct cars since the transmissions were weaker - only rated for 500nm not 700nm of torque. Im in dallas, so if you are ever in the area and want to see the difference just message me. Im also more than capable of the install aswell.

My tranny lasted 10 days with stage 3... With the valve body upgrade too.

I am running a Stage 2 with original tranny and it hasn't shown any signs of giving up.

Car has ~10,000kms (7,500 miles) and maybe 2 dozen+ 1/4 mile passes with the SC on it.

Will run 10s all day long.

Merc63

lol 10,000km, it's brand new. Mine had 63,000km when the tranny went in a week. Now 84,000km under boost and running good. I think she is starting to burn more oil though.

mr747

^^^ i think he means his had the blower on for 10000kms

i think charlies car has the same amount of kms yours does

charliekay

Brad is right, my bad for vague explanation.

Car has 75,000kms on it, blower has been on it since approx. 65,000kms.

Merc63

Oh nice, how are u doing for oil consumption?


Nice to see another DD blower car.

Honestly it depends on multiple factors. Imo I would say if you compare the naturally aspirated performance modifications over forced induction. After my experience with Weistec modifications for longevity I would consider going down the NA route. After having my car fixed and breaking in the new trans from my car (after Weistec destroyed it) I went down the rado and renntech route on my m157 4matic. The truth is the longest lasting modified m156 I have had in the c63 w204 was the naturally aspirated as opposed to the SC. Headers and intake with upgraded ecu is plenty for high speed acceleration. Again if you have are conscerend with high milage and keeping the car w/o much upkeep then I recomend not going with weistec. I say if you want a reliable kit, the kleeman company extra makes a more reliable kit but it's more expensive. If you can learn from my mistake. The Weistec sc only puts down the same amount of power but the pre face lift w204 trans can't Handel the torque and back when I had my c63 2010 modified by Evosport we got it to 470rwhp all on NA. Which held to the 2008 Weistec sc one my buddy had. My c63 had No trans mods or power issues. So if you can get your car in real world applications I reiterate go NA with bolt ons as opposed to the sc kit. It isn't worth being the mods.

blowers been on for about 18k miles now, 30k total on the car. It's not a exactly a daily but driven frequently. 15k miles over the past 2 years. The transmission didnt start slipping till about 28k miles. Keep in mind this car sees full throttle every time its driven too. I then rebuilt the transmission with stock parts and got the valve body upgrade. We'll see how long it will hold up now. When it slipped it was only under full load/power. Driving it normally or 70% you'd never notice.

I have had the kit on my E55 for 6 weeks now. The hardware itself is top notch and trying to get my tune sorted out has been so so. I originally had the BBK 90mm TB on with the 3.0 kit, and it threw idle air control codes everyday and got continuous lean bank 1 and bank 2 codes. My other issue was around shifting, power would drop off before the shift, then it would shift, hesitate and go back to normal. I have a weistec TCU tune too.

I got aggrevated waiting for a complete tune for the 90mm upgrade, so I went back to the 82mm tb. The idle air control codes went away, but the shifting issue remained.

The car makes big top end power, but the TQ has dropped off substantially from where I was with the M113K factory blower setup. All in all it is a great product, however if you have issues that others people are not, dont expect them to be resolved in a timely manner.

Any one tried this

Should help dramatically

This is not my experience.... i just logged 2 hours of freeway driving with a 100% stock sl55 (well, i did replace my dead bosche with a cwa50, which might explain the difference)

75f ambient
90f iat2 cruising
125f max iat2 at the top of 70mph to 115mph
100f again 10 seconds later at 60mph.

This was the hottest recorded portion of my 2 hour trip.

Again 2003 sl55 with a cwa50 pump and no other changes.

Heres a log
