I hope you guys don't mind me posting a link to my build thread here. I figured it would be very informative to the W205 C63 community since the M177 is so similar to the M178 motor.

I took delivery of my 2016 GT-S Edition 1 just over a week ago. I am already handing it off to the guys at Weistec for some power and performance modifications.

As most of you know Weistec has had an M177 and M178 motor in their R&D center for quite some time and have developed a line of go fast goodies for both motors.

For the first stage of the build Weistec will be installing their new stainless mandrel bent downpipe and midpipe, Weistec dry filters and their exclusive ECU tune.

Here is a link to the build thread. I will be updating it with photos and info as it progresses.

1) The wheels on the E1 are the best available at this time.

How many runs did you do?

jrcart

I only got in 3 clean passes, second pass of the night was quickest and was done while the sun was still out and fairly warm temps. I wanted to wait until later in the night to try another pass to see if I could improve with cooler ambient temps but as you could see in the video it got a little foggy after the sun went down and the track was actually dewey and a little slick.

Wow an 11.4 @ 126 MPH is moving!

Even if the C63S is 2-3 tenths and 2-3 MPH slower, it would be amazing. Add a simple 100HP/100TQ flash tune and these cars are going to be monsters!

jrcart

I agree. I honestly believe my GT-S is a 11.25 second car stock in good conditions. I think the C63 S will be a 11.5 second car with stock tires and a good driver in good conditions. Throw on a Weistec tune, downpipe and some drag radials and both cars are in the 10's.

The most amazing part of all of this is that my CLK Black Series could only run a 12.1 when it was stock and it came from the factory with 4 more HP than my GT-S. In order to run an 11.25 I had intake mods, high flow filters, long tube headers, cat delete and race gas tune. A 100 shot of nitrous got me down to an 11.00. Now we are talking about stock cars with less HP running these kinds of times.

Thanks for posting the thread here, watching the engine grow in hp and torque will be exciting for everyone, as well as educational.

Holy crap that thing is fast!!

This is what we've all been waiting for & those numbers are pretty impressive. Thanks for sharing

Excellent my Brutha! Incredible #'s for Bone Stock But... But.. Say it aint so You dumped your SLS Black Series Monsta' Argh that was wayyyyy sweeter & much more of a beast.. Too bad you couldn't keep them all... But I'm guessing it was in w/New out w/Old argh... SLS Blk was a keeper esp after ALL those choice Wiestec Go Fast goods

Edit: I haven't clicked over to the build page yet.. I'm goin to fathom a Post mod HP guess here now, Stock it's what 500 odd BHP? I'm bettin' Wiestec cranks it up to 600-650 whp.. Gotta have a small range as I'm not even certain what she makes in Stock form... Good Luck & enjoy another epic build! Lastly if you were able to drop that 60' down from 1.88' on that 11.40 run to a easily believable 1.68 that's 4 tenths off the big end as you already know & a very capable Basement 11.00 1/4 in same weather etc.. Just a slight improvement in 60' dayum that's a lil' factory Hotrod right there & w/mods I wouldn't rule out Basement 10's @ 136+ mph that's my 2nd Post Tuning Perf guess

Ya, I thinned out the heard a little bit. Might be picking up something much badded than the SLS this summer.

The GT is a quick car, I have only made three passes with it so I know it will go faster. I think it can go 11.25 the way it sits on stock rubber. I am looking into seeing if some 18" wheels with some DR's mounted up will clear brakes and fenders. ECU tune, Weistec downpipe and DR's and this thing will be well into the 10's.

Thericker

Agreed.. Though dont you think you can lower that 60' to 1.70 - 1.78?
