For those of you who missed the first part of this , its in the v-8 capable transaxles section.
I leaked one of the dozens of very basic midi plans I have drawn and horizonjob convinced me I should share it.
It's here.http://sketchup.google.com/3dwarehouse/ ... revstart=0
Had some fun with jokes about it falling over and it being light because its only 1/2 a car.
"From a quick tube count I would say mine run 10 - 15 lbs. per foot thru the cockpit. Depends on tube sizes etc."
My take on the weight penalty per foot for my proposed design.
I assume the cockpit and front end stays the same regardless of engine choice. Remember I am just "thinking out loud" here. I was actually thinking of just building the front end and cockpit first . Should be the same regarless of powertrain choosen.
So the only difference in weight would be from the various powertrain weights and the chassis length required to accomadate them.
re the chassis weight in rear section
4pc 1"sq x .063 x12" tubing main frame rails=3lbs/ft
3pc 3/4" x 063 x 14"(due to angle) diagonals tubing=2.2lbs/ft
3pc 1.5" x .095 x 14" tubing roll cage and brace=5lbs/ft
1pc .050 x 12" x 14ft alum sheeting(enough to cover top ,bottom and sides of 60"x24" body)=10lbs/ft
total = 30lb/ft
so adding 18" to the car to allow use of c5 diff adds about 45lbs to chassis and body plus whatever the weight difference between an audi box and a c5 box is (estimated at + 75 lbs) so about 120lbs'
