Equation of a circle:
R^2 = x^2 + y^2
Dia R_ y y2 x2_ x
32 16 5 25 231 15.199 Rear tire trip point
26 13 5 25 144 12.000 Front tire trip point
3.199 Trip point difference
So on my car the beam trip points are 3.199" different than the wheel base. ie 111-3.2=107.8

And for Cudabin, I think he has 31 and 26 tires:

Dia R__ y y2 _x2___ x
31 15.5 5 25 215.25 14.671
26 13.0 5 25 144.00 12.000
2.671
And with a 108" wheel base, that changes the trip points to 108-2.67=105.3" (pretty close to my original estimate in post above).

Wow Jim! You never cease to amaze me... thanks for all the great tech.

Greg, I agree with you as my best ever 60 foot was a 1.25 and i have pulled a couple 1.27's so far.

I need to build some taller limiters for the upper control arms so that I can leave the front end loose, yet limit the wheelie.

It is fun to see nothing but sky for the first second or so, but it won't win any races if i cant repeat.

Cheers,

Arnie
