I will be updating and outlining this install as information becomes available. The Nag1 transmission is reasonably compact for a 5spd overdrive and extremely tough. Much smaller than the truck RFE transmission. This is not only a option for a Gen3 hemi but also small block guy too. The beauty of it is it has a 3.59 first gear and a OD. Hers the math compared to a Torqueflite.
545RFE* 3.00 1.67/1.50 1.00 0.75 0.67
NAG1 3.59 2.19 1.41 1.00 0.83
Torqueflite 2.77 or 2.45 1.55 1.00
3.59Nag1/2.45Torqueflite x 3.23 rear gear = Equivalent of a 4.72 first gear in a torqueflite car .83x3.23=2.68
3.59Nag1/2.45Torqueflite x 2.76 rear gear = Equivalent of a 4.04 first gear in a torqueflite car .83x2,76=2.29
Remember the Nag1 is in 4300lb cars with 500hp engines
In a drag pack car we will be using a ratchet shifter.
Typically on from an old LX, say 2005 Magnum etc…..salvage yard find, inexpensive.
In our test Turbo Jeep, on the dash, shows that it is in drive etc., but we don’t have the auto-stick hooked up where it will show 1,2,3,4,5 on the dash.
I am sure there will be more options as we develop this product. I will be looking into incorporating LX style shifter into a factory console.
Pretty simple
Inputs needed:
* TPS
* Wheel speed / drive shaft speed
* Shifter if available
* MAP for tuning the street driving
* Brake light for unlocking the converter when the brakes are hit.
