IMO, more than 30hp for a tenth, a lot more.
At 3800lbs, going from 11.50 to 11.40, the moroso chart shows it would take 13hp, about the same for going from 115mph to 116mph.
So @ 3950pounds I need to find over 50 horse to go from 11.40 to 11.00 ?
Thinking of swapping from Eddy RPM STD window to the TF 240.

If everything is working as it should.....
11.40 is 115.2mph, and is 8.49lbs/hp
11.00 is 120.0mph, and is 7.52/lbs/hp
If your car stayed at 3950lbs and you did nothing to make it more efficient, then it should take an extra 60hp to make that jump in performance.
