How much E.T will I gain with this?

Well i ran a 13.9@98 mph with a 1.9 60' with bolt on's.

Then I upped the timming from 15-17, installed a 180 deg thermostat, and ran a short belt(no p/s). I then with the same 60' being 1.9 I ran a 13.4@101mph.

I KNOW I could have done better because I kept dropping my times, from 13.7, 13.5, then 13.4 but I quit running because the line was getting LONG. It's a worthy mod and you will see a good difference.
