OK Running around with my little 93 Van I noted how much power is lost going into OD.
It is more than you would think a 4th gear would lose, I mean it really drops the power: any load and pop it has to drop out of OD.
I was thinking of adding a seond OD Behind the auto and in some cases run both, but if I feel such a drop with the stock OD I fear it will bearly be able to move in double OD.
So I am not thinking a Under Drive and a very tall rear end gear...but that would end up being something like 2:40 or less...
So how well does a under drive work??
Any one used one?
