How are you activating your GVOD?
I have a manual transmission.
The GV supplied computer module is no longer used; I think I used it for maybe one day. As a splitter, it shifts painfully slow. So I shelved it. In another thread I said I had never used it but I forgot that it was installed for a few hours.
What I did was install a tiny micro switch into my shift-ball and used it to trigger a relay to engage the shift-solenoid.I installed a small LED under my tach to indicate when it is engaged.
It still takes a few micro-seconds to shift, but those are burned up during the pulling of the stick; and on full-throttle runs, I don't clutch on the upshifts.
To outshift at WOT, I hit the electric-shift switch a few micro-seconds before tugging on the stick, and make no other concessions to the shift. By the time I have completed the shift, the GV is out.
On the inshift,at WOT, I just hit the button and let her rip, no clutch; BAM! 1350 U-joints solved the carnage,lol.
For use Around town; I decreased the clamp load on the CenterForce, and installed an organic disc. I found the CFII disc too harsh. The flyweights give me all the clamping I need for my little 367. I shift at 2800 around town, before the flyweights begin to kick in.
My ROAD-ratios with 4.30s and the CommandoA833 are 10.97-8.56-6.82-5.32,
splits of .78-.80-.78; these are what I used in the Eighth, for 93@about 6200(with 27" tires)
Splitting a Torqueflite at WOT, I think would be a sort of breakeven situation in the Eighth, Cuz what you gain in the shorter powerband, you may lose in the outshifts. But if you gear it right, it will give you a short shift from Second (torqueflite) to 2-od, which you might see in your 1320-ET. The rpm drop from 2 to 3 in the Torqueflite is .69, so shifting at say 6500, this is to 4500 for a drop of 2000rpm. Whereas with the GV it would be .78, and ~600 rpm less. To do that, the rear gear might have to be changed, leaving you with whatever TM you get, and so your 60ft might eat up the top-gear charge. IDK, hard to say. It sounds good in theory, but with a BB, IDK if it would be worth it. Your dyno curve might help settle it.
I know for my 367 combo, the four tight ratios, by weight and trapspeed, the Wallace kicks out 433 hp. I am pretty sure my 367 is not there with it's smallish 230*@.050cam, and just OOTB Eddies.
With a regular A833, splitting is is IMO not useful . The ratios are
2.66-1.92-1.40-1.00, with splits of .722-.729-.714, pretty tight already. but splitting adds , in red;
2.66-
2.07-1.92-
1.50-1.40-
1.09-1.00-
.78.... and splits of
---.78---.93--.78---.93--.78--.917--.78
As you can see by the .93/.92 type numbers, it's a lil abysmal.
