I wish you all well, truly. But I do not buy that a 4.0 engine with less boost than a stock Lightning is flowing more air mass than the 5.4 engine with the higher boost. I know that the turbo is more efficient, and I know that the positive displacement units force air in. The air intake temperatures would have to be extremely poor in the Cobra and Lightning to account for such a disparity.
I want to believe it, I would truly rather have whatever system makes better power, under the curve. Regards,
Don, you might want to tread lightly here bud, James isn't exactly a noob here. In your rebuttle you pretty much hit the nail RIGHT on the head, which is that his turbo runs one HELL of allot cooler than a Heaton on that Lightning. Also he is intercooled which increases power as well and in turn requirements of the MAF. Also, he IS running higher boost then a Lightning is too. IAT's are REDICULOUS in those Eaton superchargers. Probably about 100+ degrees hotter than James' turbo. James is not mistaken at all when he says his L-MAF is about to peg.
