    1390 Question

    If an un-ported 1200 was currently running around 76 mph, what type of top end numbers could one expect by going 1390?

    Daughters unported 1200 ran 75s in the heat last Sunday with 95 temps and 1200 grate. It can be done and the info on how to do it is on ths forum.

    To answer your question I would guess 3+ judging from what the other GroupK 1390s are running.
