Sounds like a cool project, can't wait to watch it happen. 
Here is some conversion for the 1/8 mile times for you, of course it's not always exact, but they'll be pretty close.
7.00 in the 1/8 is around 10.9x in the 1/4.
7.25 in the 1/8 is around 11.3x in the 1/4.
7.50 in the 1/8 is around 11.7x in the 1/4.
7.75 in the 1/8 is around 12.0x in the 1/4.
