Couple of things... That chart has something they are not telling.. The hoods of the GT and SS were open, fans blowing on them, with CAI. Genny had no such advantage, and was using the stock air system (flapper and all). Also, the dynos have a problem with the 8 speed auto. And if not driven correctly on the rollers will under report HP. All kinds of odd dunno factors on how the measuring goes in could easily under report HP on the Tau.
In real life, no matter what some 4.6 owners with phallic envy say, the 5.0 Tau has won.. Period. Combination of the better 8 speed gearing helping offset the weight problem, and possible the GTs had their CAI heat soaked, or stock systems, bad driving, whatever, first Generation Gennys will continue to hold their own, and accurate reports of beating GTs and other cars will continue. Regardless of the keyboard naysayers.
I for one have had previous fun mocking the Tau for being a copy of the modular V8 system of Ford. Which is true.., however, I will defend the Genny, and people who have won over certain cars. Those phallic jealous others who mock these real life wins, can keep on yapping.
In the past I was mocked because I beat (with my first Gen Genny) a new M4. Well. It happened.. Late at night when I was getting gas, I heard the horrible sounding (sounds like a 1967 Ford of Chevy straight 6 panel bread van without a muffler and running on nitrous) M4 racing himself from stop light to stop light. No traffic. I was finishing up and pulled out. Anyway we raced from 30mph on, and I pulled ahead of him slightly by few yards. Only way this could happen is if he could not drive it (he was wide open because it was so loud beyond belief beside me and as I pulled past him), his vaunted water cooled
intercooler was heat soaked, he was running crap gas, or something. The outcome did happen.. And sparked horrible drive by verbal assaults by numbskulls. It should not have happened.. The M4 had at least 450 lbs advantage, and 5-10 percent more published power. It was a manual. Whatever... He lost that time.
Oh, BTW.. Will be posting BMW latest vaunted tech "innovation" later... They have designed a J. C. Whitney inspired water injection system to "increase mileage and performance by 10-18%". Sound like a claim right out of the Whitney catalog. Geez.. Can't the German come up with something innovative? Using a old dog trick which they claim will be in every BMW in the coming years.. Instead of fuel to cool down the combustion process to prevent damage, they will inject water... I have an idea.. Design a motor that does not need either. This is silliness to bandaid design flaws.
