    cooling system fill

    thanks guys, i'll give some of these a try. I'd never used the mold design stuff, the cavity option sure looks good for the more complex shapes.

    cooling system fill

    Perhaps this is a stupid question but I'm having difficulty and a quick search didn't resolve my problem. Is there a way that I can fill a coolant passage in an assembly with a liquid, I'm looking to get accurate moments of inertia and weights for the assembly but the cooling water will have an...

    engine balance textbook recommendation?

    that's exactly what I was looking for. Thanks a bunch Hemi. I very much doubt that it's changed in the last hundred years, much less 20 :)

    engine balance textbook recommendation?

    can someone please point me in the direction of a textbook that will explain to me the concepts for calculating flyweigh mass to balance an engine? thanks in advance guys.

    ignition advance as RPM increases

    Thanks Mike that's been a big help I've ordered a couple of papers. I really appreciate your taking the time to point me in the right direction.

    ignition advance as RPM increases

    MikeHalloran, I would be very interested in reading the paper mentioned in your first post, I've searched the SAE database, but I don't seem to have enough criteria to find it. If you could point me in right direction I would be very appreciative.

    Cryo freezing bearings...........

    why would cryofreezing a roller bearing be a bad idea? traditionally the materials in the race and the rollers are the same so thermal contraction shouldn't be an issue? that said I've never tried it, else I'd not be asking. as far as handling LN2 goes. Would it make sense to use a mesh tray...

    Breaking distance

    in my mind, the difference in tire size isn't particularly important. The friction force will be determined by the coefficient of friction and the weight of the vehicle. The differences in weight will balance as that much extra mass must be stopped and it is proportional. Therefor, the brakes...

    Inline 6 Exhaust Sound

    the cherokee uses a tubular manifold, if my memory serves it's 3 primaries to the first collector stage, then 2 into 1. I haven't had one in front of me in a few years, but I believe it's a cylinder 1-2-4 on the first collector, 3-5-6 on the second. depending on the year of the cherokee they...

    Exhaust manifold design

    I will also vouch for Blair's book, very good quality for formulas and empirical evidence.
