    Ok with a few test runs under my belt I can summize that adding the long intakes and restricting the intakes slightly to promote constant pressure does have a positive impact, however, it is mostly felt in the midrange.
    There is a noticable smoothing of throttle transition from low to mid, and a strong (almost frantic) pull through the midrange.
    I got it up to 94mph, but I ran out of road, it was still pulling well.

    I then added 140 main jets and tried again, 96 mph on same road, so no noticable differences with a bigger main.

    I think if I went up to 32 teeth on the back I would have smashed my goal! video to follow....
