Tim @ MPH turns out badass cars... no doubt about it. The problem is that 2V cars have actually been showing better numbers than their 4V brethern. The one car is running 25psig+ and spray. The turbo cars are doing it on boost. What is the compression in those engines? How about head work and cams? Tim's success comes from a complete combo, including engine work and suspension/chassis set for the track. I just think it is a bit inaccurate to make a blanket statement stating 03/04 Cobra 2.8H setups are running with heavily-modified turbo setups. Either way, I'm seriously considering the 2.8H in the next year.
