Re: Differential Locking - a Racing View of low traction
I guess I will jump in with my experiences autoxing my 86 4kq last
year. I found the car to work best with the diffs open for most of the
run. If there is a high braking area (well all are hi
gh, I mean dropping a lot of mph) I will lock the center diff on the
straight becasue the braking is much better. Without it locked, the
car had a tendency to lock up one or both of the front
tires very easily.
Aditionally, if there was a really tight corner to accelerate off of in
first gear, I would lock the center diff before of during the turn.
This will allow the car to accelerate much harder wi
thout spinning the inside front as much.
The downside to working the switch during a run is the complication it
adds. If the course design allows for sufficient time to throw the
switch and engage the lock, I do it. On an average 60
second course, I picked up almost 1 second if I had a braking and
accelerating opportunity on the course.
I have noticed that my times are worse if the center diff is locked for
the entire run... more understeer.
I know Glenn Powell likes to lock the rear only. This did not work for
me at all. I think it has to do with the fact that I was racing on
BFGs last year and he ran Yokohamas. I have not decid
ed on a tire for this year.... any ideas?
