Do you guys think I will see a large improvement switching chassis to a 92-95cx/vx hatch?
I know guys are talking about putting electric motors on their engines to give a few HP boost, and if this calculator is close to accurate, I have to think I should see a huge improvement in my car wanting to stay in lean burn(making enough power to overcome the drag). I think i calculated that yesterday and it was a 20% reduction in power needed.
I know people have said just aero mod your car to achieve the same results, but it would be easier for me to swap I think.

If you do the aero mods you'll be practicing load avoidance which is the most elegant form of engineering.
It would be like adding insulation R-Factor to your home.You're reducing its inverse,the heat transfer 'coefficient,' and with the same indoor/outdoor temps,you can be just as comfortable with less heating or cooling.
If you consider adding S-Factor to the car,then its inverse,the drag 'coefficient' is reduced,and you can operate at the same speed on less.
This efficiency will be built in to the car and it can't ever go out of tune,nor ever require replacement parts.
My CRX is at CdA 0.404 sq meters with the kit.You could easily match it with what you have.
