    • Porsche 997 GT3 RS 3.8 liter versus GT3 RS 4.0 on the dyno - 419 vs. 457 rear wheel hp + highest specific output list

      We bow down in respect to Porsche. This is some of the most impressive factory stock specific output we have ever seen. To hit over 100 wheel horsepower (not crank horsepower) per liter is a feat we have not seen many factory stock motors over 4.0 liters accomplish with the F430 Scuderia being the only other one in recent memory with 459 wheel from its 4.3 liter. 457 wheel horsepower in STD correction from a 4.0 liter flat-6 is absolutely absurd and this is by far the most powerful production naturally aspirated six cylinder the world has ever seen.

      The 997 GT3 RS 3.8 hits 116.38 wheel horsepower per liter. The 4.0 hits 114.25 wheel horsepower per liter. The F430 Scuderia is at 106 wheel per liter. The GT3 RS is rated at 125 crank horsepower per liter but that crank ratings even looks conservative to us.

      How about that the GT3 RS 4.0 is making just over 100 horsepower at the wheels more than an E92 M3 4.0 liter V8? Same displacement, two less cylinders, and 100 more at the wheels. Ladies and gentlemen, that is some of the most impressive engine building the world has ever seen from a production naturally aspirated six cylinder motor. Porsche squeezed out a ridiculous amount of power and 4.0 owners are certainly getting their monies worth. We do not have enough superlatives to bestow on Porsche, phenomenal.

        I personally cant stand to look at any porsche. I can appreciate what goes into its design, but aesthetically, its got to be the most un-appealing car to me

        Well the 911 is boring, I agree, but the new Boxster, Cayman, Panamera, and Cayenne are all TITS.

        More to come.
