Easy calculations for 1/4 mile times:

Found this on the 'net' while searching for info on "wheel hop".

To estimate your potential 60 ft. times and 1/4 mile ETs, IF your chassis is correctly set up--for vehicles running up to 130 MPH or so in the 1/4--for traction-limited(LOL!) vehicles, predicted ETs are lower than can actually be achieved.


Optimum ET= 1,320/quarter-mile MPH
or,
654/one-eight mile MPH

Optimum 60 ft. time=168/quarter-mile MPH
or,
132/one-eight mile MPH

1/8 MPH=.786x1/4 MPH

For example, if you can run 100 MPH in the 1/4, you should be able to run an ET of 13.24 sec. and a 60 ft. of 1.68 sec(LOL!). In the 1/8 mile, you should be able to run an ET of 8.31 sec. at 78.6 MPH.

These formulas were derived theoretically and then modified based on real world experience and NHRA National Record data from the 1970s.

1320/122.62=10.76 (actual run was 11.858@122.62mph hot lapped)

Looks like I just moved up a few spots in the rankings...
Don't forget to add the N(that run was on Nitrous)

LMAO........your "theoretical" short time should be a 1.37
