    Alternate crossplane V8/I4 crankshaft implications

    6 post-it-notes later and it's either RRRRLLLL or firing the 4 "front" cylinders followed by 4 "rear" cylinders. That's good, this idea can live outside my head now. Regarding cylinder numbering the GM LS convention is cylinder 1 is on the front left corner of the car (front mounted...

    Alternate crossplane V8/I4 crankshaft implications

    Your choice of 4 options (or 8 if you want to fire 4 cylinders on one bank followed by 4 on the other) Greg. Based on GM LS V8s it would be 1 4 3 2 6 5 8 7 but this hits the four front cylinders followed by the 4 rear cylinders, there would probably be a better option, I'll have to look into it.

    Alternate crossplane V8/I4 crankshaft implications

    Dang, lost my reply. Cheers! I'm not talking about using crossplane crankshafts in place of flatplane crankshafts, just wondering why nobody has tried an alternative crossplane configuration. While they aren't common, the pros and cons of inline 4s with crossplane crankshafts are fairly well...

    Alternate crossplane V8/I4 crankshaft implications

    Hi all, I've been pondering crankshaft orientation for a while and am trying to work out why all V8 crankshafts are "up left right down" and not "up down left right" Intuitively and based on fairly simple calculations it appears that the latter configuration would reduce the first order...
