Also, you must consider the fact that the cars were probably tested on different days, with different atmospheric conditions, with different drivers, etc.webby said:not a stupid question. I think it's been raised by a few people when they saw the 0-60 and quarter mile #'s. I don't have a good answer really. The Type S does win in the weight category. It obviously loses in the LSD category. The LSD will help the SI, but I think it will make a bigger difference when mods are put on the car - especially forced induction. I think if the same turbo setup was put on the type S and the SI, the SI will walk it because of the LSD advantage. A lot of things determine speed besides the engine and tranny. Even factors such as aerodynamics can play a major role in how quick a cars is - hence = drag.
A better explaination would be that an LSD distributes torque "from the wheel that slips to the wheel that grips" (to borrow some old Subaru ad-speak). With an open diff, this obviously doesn't happen and the wheel that is receiving no grip is allowed to keep spinning. This is the challenge I will once again face in autocrossing my new 2006 Civic... I had an LSD in my old 93 Civic for the last 3 seasons, and I got very used to it to say the least. I'll have to rely on chassis setup and smart driving to overcome this minor setback.webby said:lsd does help stop wheel spin to an extent. It gets the power to the ground - and spins both wheels together. Without the LSD you're basically spinning one wheel. It also helps on auto x stuff in turns etc.
