New to this platform. Performance modifications for 750WHP
***Disclaimer***I’m new to this forum and have been looking but can’t seem to find the exact performance section. So if this is the wrong place please direct me where to post.
Anyhow I come from the world of American muscle and high power supercharged V8s. I had a 2012 Camaro SS, A 2013 Camaro ZL1 that I modified into the 700 HP range at the crank (600 at the wheels). Then I got a 2016 Z06 that I made into an 860whp monster (1000 at the crank). I did full bolt ons, a cam, procharger f1A and methanol in that car. But with a 5 year old it wasn’t practical. So I’m looking for a 4 door tire burner. I’m between the CTSV V3, c63 s, E 63S or the new black wing ct5 v manual which may also have the supercharged lt4 ot possibly the ZR1 LT5).
My question here is two fold..... I’m looking at getting a C63 s or an E 63 S. They both have the 4.0L Bi turbo (twin turbo) engine. Is the c63 s just tuned down 100 hp and rwd (as opposed to the e63 s AWD) or is it completely a different motor with different restrictions?
Second question, is the w205 c63s capable of making 750WHP range with the stock turbos?
What are you guys seeing as far as hp gain packages? In the GM realm, if you’re staying with the stock supercharger, it’s headers, cold air intake, pulley changes to get more boost out of the supercharger, a cam, methanol, and/or e85 depending on fuel limitations.
what are you guys doing to get the most power out of these cars? What’s a typical package if you will?
again sorry for all the newb questions but I’m not too familiar with this platform. I’ve searched the forum and can’t quite find the answers I’m looking for. Thanks.

Yes the c63s and e63 have the same m177 engine.
As far as power "packages" and stock turbos go...
1. The stock turbos do have a limit and really should not be pushed past 650whp if you care about reliability at all. So I would not recommend pushing them past that
2. To get to 700/800 whp+ you would need catless dps, upgraded turbos (pure or weistec), upgraded drop in filters or CAI and WMI. Can also add track exhaust for a few more hp.
3. I have a custom stage 2 tune with catless dps, drop ins, and track exhaust with stock turbos. I'm currently around 630whp and stable.
The platform is pretty bulletproof from an engine standpoint. Theyre all hand built and unless you find a one off lemon, they love getting beat on. Biggest benefit of the e63 is the AWD, but I love my coupe so far after coming from an f80 m3 and camaro before that. I loved the ctsv too, and almost got one of those instead, but at the end of the day the engine is great but they have lots of issues, so opted for the AMG.
Hope that helps a little...

mat 630whp have you run it on the track (1/4)? If so, what times are you seeing?
and I’m assuming these turbos are just slightly smaller than the e63s?

This is inaccurate - The E63S has unique pistons/camshaft profiles, huge change in cooling capacity and turbochargers.
The displacement is common between the E and the C, but it has a much lower compression ratio (8.6:1 old school big boost low compression on the E63S, 10.5:1 on the C63S).
The cam profiles are optimized for the boost curve of the E63S, and the E63S uses larger impellers/twin scroll hot sides
Biggest difference is going to be in the drivetrain. The E63S has a fully variable torque split AWD system. The C63S just cant hook up.
You should be able to put down 670whp with just a tune on the E63S. The issue is with higher power levels, the transmission computer and central powertrain controller (TCU/CPC) need to have their torque limiting thresholds raised, and at this time there are only a few tuners that do this service.
With downpipes, filters and an ECU/CPC/TCU tune, 750whp is easily attainable on 93 octane. The block itself is good for 1000hp+. Hell, mercedes sells half the block (the m133 4 cylinder in the last gen CLA45) with a higher specific crank output of 381hp with a warranty. (that would be a 760 crank motor) and folks have been tuning those to 450whp without issue.

I don’t know anyone who’s making 600 wheel hp or near it on stock C63S turbos. If anyone claims to, please post a dyno sheet with your mods, octane, water/meth, etc. E63S turbos are more than capable of making well beyond that.
