W5M6A Gearing

I was thinking for the last few months and finally gave it a shot for the last thirty days......yes, I drove my car without using first gear at all (except implicitly when reversing).

Why can't we have a setup where Gears 2, 3 and 4 are changed to 1, 2 and 3. and then we add a new 4th gear which is shorter than our current 5th, and a new 5th that would be taller than our current 5th?

This is of-course, only for those who never need to launch or who never need speed straight off the line.

I really did not feel the need for 1st in the last 30 days and I was not slipping the clutch too much either with my SSP/Exedy Twin setup. This was with 2 people (including me) in the car.

:nerd:

interesting proposition... sub'd
sounds like that's something you'd run by a transmission outfit such as Jack's or Shep to see how feasible it would be and how much it might cost.
Wouldnt it be easier just to add a 6th gear instead of moving them and adding a 4th? You would still have the benefit of 1st with a taller gear for highway cruising.

Probably not while re-using the OEM trans case. I think the idea here would be a retro-fit that eliminates 1st and then relocates 2nd gear in the transmission to the physical former location of 1st, repeats this with 3rd and 4th and then splits 5th gear into two. Then you'd end up with a total of 5 gears and re-use the bulk of the internal parts of the transmission.

Exactly! not to mention, you get to keep your gear thickness at a good strength point.
Also, we would be able to sell the now defunct 1st gear hardware to drag racers who might break theirs'.

our jump from 4th to 5th is too high IMO. Keeping the 5th is also an option for the cost conscious I guess.
Could another option be to just get a 5th gear that is not as thick as ours and put a 6th gear in there along with the smaller 5th? Instead of splitting 5th into two gears after replacing 1st. Just throwing ideas out there, i dont know much about this topic but I always with we had a 6th gear.
just get an SST?

for SST money you might as well buy a sequential unit..:whipping:
^^ Brand new SST is like 8 grand. Sequential dogbox.....20-30 grand.


.
not to mention, 1 rules at DD, the other rules at high HP circuit racing...

as always its a compromise :)

Unless you are going to tell me that you are going to have the SST TCU decoded within the next month AND a lump of cash comes my way........no way my

1 is good, but I really did not feel its need so much in the 30 days I tried driving without it. I am ONLY talking about circuit cars here. Not to mention, the cost is sure to be less than 8K.

That was the problem with the CT9A 6 speed trannies. They would break since they were weaker once you got into serious power. My only reservation with this idea is how Reverse would work since we use a combination of 1 and 3 in our transmissions.
pff, who needs reverse...
I sense sarcasm.....but still, lol, Even for a track ONLY car, I think reverse is a must.

you can always have someone push it :p
