    NASCAR's shrinking and frankly give it all the stick you want unless they're racing at Watkins Glen. Then pull up a chair and get some popcorn. The big point is Ford has an aerodynamics center for NASCAR and their half-baked, nostalgia-fueled GT run. And M-Sport got access to it.

    That is some kind of technology to make pushrod thing fill cylinders and burn better that beautiful multi-valve pent roof motors...

    I have never had any interest in going in ovals, less interest in ass-fault...
    But Circle track in general--not just NASCAR, but the whole field of circle track racing is the ONLY racing in America worth a god dame dime.
    Because its the only racing with any depth of competition..

    Remember that when the discussion swings around to US and Canadian rally, and worse, rally-cross. Its all BS and hype and lies.

    "Making the most of the increased technical support from Ford Performance, the Rally Mexico winning Fiesta made its way to Indianapolis in America earlier this month for some aerodynamic research and development at the Blue Oval’s state-of-the-art wind tunnel."

    NASCAR motors make more BMEP than those poooftie little girlyboy F1 motors.

    To illustrate how ridiculous this suggestion is (which is like comparing apples with pairs, by the way, as the F1 engines are turbocharged, while NASCAR ones are naturally aspirated), I will do the calcs for each of the two types of engine using figures significantly skewed in favour of the NASCAR engine, so here it is:

    NASCAR engine:
    - Top power: 660 kW @ 8 000 min-1 (remember figures are intentionally distorted to work in NASCAR’s favour)
    - Engine capacity: 5.85 litres

    F1 engine:
    - Top power: 500 kW @ 12 500 min-1 (remember figures are intentionally distorted to work in NASCAR’s favour)
    - Engine capacity: 1.6 litres

    NASCAR calcs:
    BMEP = (660x120) / (5.85*8000) = 1.69231 MPa

    F1 calcs:
    BMEP = (500x120) / (1.6*12500) = 3.0 MPa

    On my side of the pond, 3 is bigger than 1.69 and I suspect it is the same in the US of A, but as I mentioned comparing these two types of engines is stupid in itself as one is naturally aspirated while the other is heavily turbocharged.

    Also, for comparison purposes and using the official figures, which anybody is free to agree or disagree with, here are the calcs for a current WRC engine:

    BMEP = (280x120) / (1.6*6000) = 3.5 MPa

    Now, before anybody starts shouting how the current WRC engines are more efficient than the F1 engines, if we use numbers that are closer to reality for the strongest F1 engine (currently believed to be the Mercedes), then the BMEP is probably not less than 4.2 MPa.
