So how much power do we need to get a 12.9 at that weight? 380hp according to our internet calculator.

Using 17% drive train loss (that whas the calculator's #, not mine) that means you would need a baseline dyno run of 284whp.

How much would we need for a 12.9 second quarter mile? 324whp. That means a 40 whp gain would get us there. Sounds reasonable. Just hasn't happened yet.

With some of these initial dyno numbers coming in under 260 hp I was worried that Nissan fudged their power output numbers... but it looks like that is not true.

Anyways, just some food for thought....
I've got around 350hp 360trq and i'll usually run right at 13.01 on stock rubber full pressure. Maybe that will give you some comparison.

My 60's are also pretty terrible - 2.0+
