Still thinking about that dang car

I had another thought about the Thunderbolt Grease Slapper 2 to get better balance and more consistent handling. Instead of putting the gas tank in the front, move the driver forward and put the tank sorta in the middle, between the engine and the driver. This would do two things that could be beneficial to the performance of the car: 1) Put more weight on the front end by moving my fat ass closer to the front and 2) Put most of the weight that changes while the car is driven in the middle where it won’t drastically alter the weight balance of the car as it changes.

Doing this does create its own set of challenges. First is I will have to create some kind of metal enclosure between the gas tank or fuel cell (explosion-resistant gas tank, not the kind that you spray fuel and air in one side and get electricity out the other) and the driver’s seat, second is I will have to create some kind of enclosure in front of the firewall because I’m going to stick my legs through the one molded into the body. This brings the secondary question of seating position, sprint go kart or stretched out?

Lay back a little in this and it won't let you fall out.

If I go with legs together and just leave enough room for the steering between my feet (like in the front-engine Sprint-T) I don’t need to make a big hole in the factory firewall and have additional support for the steering column. If I go with the sprint go kart seating position most of the firewall will need to “go away” and I’ll need to add structure to support the cowl and the steering column, but I will be able to sit several inches closer to the front axle reducing my arm and moment and moving the CG closer to the front. Not to mention all that structure will add weight right behind the front axle helping move the CG forward. And there we get the major drawback to the go kart driving position, added weight. The car is already almost 100 pounds over the initial target weight, and adding more structure will not help that situation in the slightest. So to maximize straight-line performance I think the legs together position. And I just fell outta my chair while typing again, so I’m going to bed now.

Don’t take any wooden nickels while I nap.
