    We compared the actual weight of a 428 and a 520 chain a few years back. I don't remember the specifics but the two chains were much closer in weight than we expected.

    Can anyone weigh two of...

    Hey Bob, hows it going? I wasn't being serious about the fuel economy. Its part of the competiton.

    Is there a way to get the lap times from the endurance event?

    Oregon State finished endurance with the fifth fastest time but ended up 28th. Who cares about fuel efficiency anyway?

    I've heard that the cam and pawl diffs are nice because they are about the size of a can of tuna but unfortunatly, they work about as well as a can of tuna.

    In my opinion, the most important factor in choosing a final drive ratio is how easy it is to launch. We were able to drop our times 4/10ths of a second from 05 to 06 with similar power curves by...

    All three design finalists at west ran Salisbury diffs.

    We ran an open diff and it worked well. There was some inside wheel spin. No problems in acceleration. It works much better than the...

    Ian,

    That makes sense to me about the different reaction torques. I went back and read the posts more carefully and I think that you are right about the angles and toe compliance.

    I think that a 2:1 stiffness ratio would result in a 2:1 torque ratio with a torsen untill tire slip equalizes the loading. I don't know how fast the reaction time for this would be but every time...

    If you are running a torsen with 2.6 TBR unequal drive lengths could be a problem. The half shafts act like torsional springs with, I assume a, linear spring rate. The shorter side will twist less...

    Hey Scott,

    There is alot of information about the torsen if you search the forums. Personally, I would just use an open diff depending on how your suspension is set up.
