David N. I don't know anything about torque convertors.
The only experiance I have would be with ways to slip a clutch.
Or the set up of a multi stage slipper head clutch,with air lock.
If I was building a drag car I would only use sintered iron
clutch plates with steel plates.With air shifting.
This is the only setup I now how to work with.
I was never allowed to use computor controlled any thing except ignition.
But was allowed fact finding data.We did not go by torque or hp. numbers
to set up the clutch slippage.We went by engine rpm,clutch basket speed,
or rearwheel speed,with ground speed,and of course tire smoke .
There are tire dynos for motorcycles ,But you will be hard pressed to strap
a bike with 750 to 1000 hp on a dyno to get some good numbers .There are
a couple engine dynos around setup to handle what I used to do.
I am not arguing either,just tring to get you or somone to responded with
some good numbers.I didn't have them.
But I do know about slipping the drive-line power (clutch or torque convertor) To keep the engine in its power band ,& getting maximun traction,to go with track conditions.
I am under the impression that with a torque convertor you will not have
a option of adjusting stall or lockup of a turbo blade convertor.TO match
the weather or track conditions.Unless you have a electric controlled
lockup of convertor.So convertors are set at a ballpark number to perform
on the strip.I guess what I am saying is a multi slipper clutch is better
for adjustments for max traction.
On stall or slippage you want this to get to your peak torque window
with at the same time producing maximun traction.So the best stall or slippage is to match your torque.But this setting would be a ballpark
stall number.Not perfect for all track conditions.
But with a torque convertor you cannot adjust the slippage force to
the driveline.To match tire speed to track surface speed.To tune for
max traction on a given race date.
I don't see Kevin L's. torque to be to high.Since it is a drag only car.
It looked to me that Kevin L. and Cory M. both have around 3500
stall convertors.But I bet both would like to be able to control the
force of the stall or slippage, and lock-up.
The problem is that most people want a strip & street car that turn
a world class time.Well this isnt going to happin.Performance parts
made for both worlds.Are Not adjustable enough to be at a perfect performance level.
To be on the fastest SCCoA list.I would drop the number 2 on my torque
convertor numbers and start with a 3.This is why you buy a trailor to go
racing.Its not to haul your car home because it may break down.But also
to haul your car to the track,because its to hot to drive to the track.
David, I am not sure,I am not from the auto world, but if you would
installed a 7 or 8 inch lentech with a 3500 stall.I would think you
could maybe take another .500 off your time slip.But you would
need to mount a full size radiator on your SC to keep you transmission
fluild cool.If you still want to drive your SC to work.
You have every thing needed to go a lot faster than you are.You got
kirt K,Chris W.to help swap out your convertor for a smaller ,& higher
stall,a trailor,and an extra car to drive to work.It would be nice if one
high stall convertor could be swaped back and forth between your two
Super Coupes.
