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....
