Purpose of the car, in order:
Spirited street driving, occasional AX, occasional track days. Here's what i think i know (IMG:style_emoticons/default/biggrin.gif) LSD - Always locks wheels together under acceleration and deceleration. - Introduces understeer in slow corners. - Generally considered the better choice for the big track. TB - Only locks wheels under acceleration. - Acts like a open diff if a driving wheel is off the ground. So, the question is, what should i get for my 915??? The car will never be a dedicated track car, it's mostly driven on the street. The TB seems to be easier to drive on the street. However, the slow corner understeer of a LSD could probably be tuned down with suspension settings. The TB loses it's magick if one wheel is off the ground. In an AX setting, the suspension would need to be pretty stiff to keep both wheels on the ground at all times, would a LSD be the better choice here? Anyone compared the two back to back in a 914?

Andy,
your going to want the TB for a street car I had an interesting conversation with Paul once. he admitted to me that in a mid engine car with low power the TB might actually be better on the big track too.... I pushed him on this issue because AJRS ran back to back testing with a TB at 205rear wheel HP and found the TB faster than and LSD in a mid engine 914. Paul verified this could be the case theoretically guess what I went with in my track box with F, J, S, O, V and a 2ltr the locker and LSD are much better under braking but slower in some situations over all much too much understeer in autox and tight stuff. fun, because you have to play "dukes of hazard" in tight stuff.... but still slower. the TB does turn off and on.. and does take some getting used too. you can feel it, and it takes some mental re-learning. on a big sweeper at 80mph... you have to floor it just when your not sure your going to make the corner. This causes the car to "tuck" and make the corner. brant |
