M5 F10 tune only vs M3 g power SK II CS 630HP DCT

[lfelunden]

Both spin in 2nd gear, M5 spins in 3rd aswell upto 140km/h (new michelin PSS tyres though), my car is crazy fast, haven't been on dyno. I guess this M3 can point out that it is fast
M5 mods: K&N drop-in filters and tune
M3 mods: G power SK II CS supercharger kit + complete akrapovic titanium exhaust and DCT (630HP).



I will make some new clips whenever the M5 will have the complete IPE exhaust installed and some more boost up top!

No doubt a fast car, but I think the term crazy fast is tough to throw around...especially on this site

Crazy fast for an M5 with tune only yes, but a CRAZY fast car - no

The old and new M philosophy clashing on the highway. These two cars may both have V8's but they go about their power delivery very differently. The 4.4 liter S63TU in the F10 M5 is of course twin turbocharged and features direct injection. The motor is all about low end torque.

You can take a look at a graph here showing the output and the M5 makes roughly ~520 wheel horsepower stock. The torque curve drops off toward redline but with a tune there is a lot of area under the curve. We do not know what tune this F10 M5 is running but expect output of roughly 580 wheel horsepower, 594 lb-ft of torque at the wheels, and 130 mile per hour trap speeds from a Stage I tuned car.

That amount of wheel horsepower and that same 130 trap speed range is about what is expected out of a supercharged E92 M3 (depending on how aggressively it is tuned and what pulley/kit it is running). You can see how a G-Power SKII kit compares to an Active Autowerke Level I E9X M3 S65 V8 supercharger here. Suffice it to say G-Power is not the strongest option especially for the money on the platform.

What this basically boils down to is the supercharged M3 top end horsepower thanks to its flat curve that increases toward redline thanks to the centrifugal blower adding torque the harder it spins versus the F10 M5 raw grunt.

It's a great run between the two and very even. The M5 with its roughly 700 pound weight penalty needs that torque advantage down low far more. Both are very capable on the highway.

Both cars were spinning in 2nd gear, when M3 got into 3rd it started pulling because of grip. My M5 was still spinning 2nd gear out and a bit of 3rd until I hit 130-140km/h, then we started to pull on him.

You should do a rematch from 3rd gear perhaps.

On the highway we did a roll from 60km/h from 2nd gear, both cars had grip, we pulled 2 carlengths upto 180km/h.. No video as my passenger at 250lb turned into a pussy LOL

@Sticky btw this is the SK II Clubsport kit, difference is 60HP!

Ah, clubsport has higher output. That makes the M5 look more impressive.

Yep, not that the 570HP version is slow, but yes it's buslengths difference against the clubsport version! Also it has full akrapovic titanium exhaust and ADV 20" wheels. I can take some pictures of it, looks really nice. Custom interior all in alcantara!

What I really want to see is a rematch
