Test runs and 5th wheel
Air system test and 5th wheelV2
I got a chance to do some driving with the air springs, and notice a few things. You need to keep at least 5-7 psi in the bags to inflate them so they move without damage. The min recomended is ~ 20 psi. At 6 PSI, the car rear is lifted about an inch more than without the spring. Conclusion. Unless you are carring weight, it would be better to take the springs off.
Unless you like the feeling of going down hill all the time.
I put two batteries and the spare in back to see how it would ride. The ride was smoother as one would expect with more mass. Even with two 61 LB batteries the springs only needed 8 PSI to get the height about normal.
I worked more on the 5th wheel and it's attachment to the car. I had a policy of not modifing the car so much that I could not return it to normal, so I may as well go the whole way here. I was originally thinking of connecting the motor/wheel assembly to the torsion bar that the two rear wheels are mounted to, by clamping on. I am not happy with the positiveness of that for something that could be hit by a piece of truck tire or frozen slush.
The new improved plan will make an aluminum sub structure that connects to the sprung chassis, and clears the torsion arm and wheel support arms. It will be bolted through the bottom of the car so that it is made part of the structure. The air cylinder/5th wheel will attach to this sub structure. It will be made strong, over built.
I am not going to use chain for the drive, I will use a super strong gates cogged belt drive. The same thing the new Harley motorcycles are using. Hope to get Gates to give me the drive components. Curtis sponsored me with a 1204 36-48V 275A PWM controller, and two big decals for the car.
Vicor is also going to give me the BatMod constant current power supplies that I will need to regen back into the 48V battery if the oppertunity presents it self.
