Strength of the supercharged E92 M3 S65 V8 top end - DCT M3 puts buslengths on a Ferrari 458 Italia
Many people look at the M3 torque figures and horsepower and think peak numbers tell the whole story. Well, they do not. The M3 motor when massaged with a little boost becomes an absolute best namely up top with a centrifugal blower which builds boost with RPM. The M3 revving to 8400 rpm in stock form when paired with this style of blower makes for a very strong roll on racing car. Don't believe me? Check out the video below of a 458 Italia being blown away on the highway.
Now the 458 Italia is no slouch. It's a very fast car even in stock form. This M3 is packing some heat though running an ESS-VT2 625 supercharger kit with a different pulley for more boost for an output of 613 horsepower at the wheels. The owner posted his dyno graphs with various pulleys showing the effect on output
With 613 horsepower at the wheels and a dual clutch transmission just like the Ferrari it is no contest considering the 458 Italia is down roughly ~150 horsepower at the wheels and it shows.
Thank you to @BlownE92M3
