^^^ yes... way shorter gear for 1/8th mile (I was thinking 5.30).

Here is a calculator:

There are many and some use different algorithms. I found one page that had three different algorithms so I plugged in my weight mph and et and found the one that had matching hp for the mph and et calculator.

Just google: MPH HP ET calculator... and you will find many.

Looks like you're somewhere around 360-370HP to the pavement and would be about 12.70 @ 108 mph in the quarter mile.
