OK, so up until this point I have been showing you the physical progress in the build of this car. Today, I am pulling the curtains aside and showing you some of what has been going on in the background. Not that I think anyone really has any misconception about what we are doing, but I thought you might find it interesting to see the mathematics that have and are going into this car.
This car is technically speaking a frame off tube chassy fuel none modified dragster.
When we started building the tube chassy these are the calculations we went through to determine how the tube chassy was to be constructed.
Weight Distribution

CG height= ——————————
Distance raised X Overall weightThere are a lot more of these equations, for Drive wheel torque, Wheel thrust, Weight transfer, and Lateral Acceleration Lateral weight transfer and Centrifugal Force. These cover the frame and the positioning of the rear-end.
In the next Installment I will go into the calculations used to build the engine itself, I’d give you those equations now, but the engine is currently at Larry Holt Speed Specialties (Larry Holt is a famous 60’s and 70’s drag racer you will find his record listed here at # 201 of the All-Time Quickest Supercharged Gassers http://www.draglist.com/lists/
Larry Holt passed away last year, but his son and grandson are keeping the tradition alive and well here in San Diego California. Part of the tradition they are keeping alive is well, basically checking my math to ensure that I used all the correct equations on the build of this engine, which is why I am not giving you those equations just yet.
Yes, we have all of our equations checked and verified by seasoned professionals in the drag racing industry before we build based on them, and checked again afterwards to ensure that what we built conforms to those equations.
