Mental musings

[v2squared]

What I have now is a 1966 Triumph 2000, with a Kubota V1505-T, Corolla T50 5 speed trans. The current upgrade I’m doing is an overdrive gear case, to get the 4.1 rear end numbers down to a 2.4 to 2.2 final ratio. also thinking of going up to a 70 series tire from the 60’s I’m running now. Now the car will do 53 mph and getting about 50 mpg, at 3k rpm.

What it looks like number crunching wised is.
2.4 overall ratio with 205 60 15 with 75 mph at 2500
205 70 15 with 75 mph at 2300
2.19 overall ratio with 205 60 15 with 75 mph at 2300
205 70 15 with 75 mph at 2100

Next stage is to adapt a hydrostatic transmission set up to the diesel. This would allow the ICE to run at a constant rate of 2100 to 2200 rpm. Wanting to see if it works as well on my car as a friend’s bike.

What this post is about is the 3rd stage.

An electrical motor driving the pump would only need 50 hp to turn pump, as that would be more than the current ICE 44 hp max. With the electric motor running an either 0 rpm or 2200 rpm I cannot see needed 15 to 20 Kwatts of battery packs and the massive controllers to operate as a pure EV. I may be wrong with this idea, hence the post.

I’m just wondering if this system would work. If it would what size of electrical motor would work, what would be the smallest battery pack needed? If that part would work is a small ICE with a generator with at least 25% more charging ability would keep the ting running?

So let the ideas and fur fly

I had an early Triumph and it loved to break stub axles. I'd keep the trans and replace the rear end. Then you'll have no British parts in the drivetrain, which is a very, very good thing.

primary reason at looking at the hydrostatic system, 1 pump driving 2 wheel motors.
