Ran the Bone Stock 2011 Evo GSR during a recently local dyno day. Their have been posting of the 2011 Evo of having a re-tune factory map and putting down more power then the 08 & 10 Evo. I wanted to see for myself what my '11 X would do.

Outside temp was around 100F degree.
It put down 269 whp & 279 tq baseline with 3 average pulls.

Is that with or without the K&N drop-in air filter? Either way, I was very impressed by the numbers considering they've never had a stock X dyno higher than 250whp there.

That was without the drop in filter. It pulled 274whp & 281tq with just the K&N installed.

Since it was 100F, what was the correction factor used?

That's pretty good power at the wheels! It seems like there's not much parasitic powertrain losses sustained on the X's..

2008 = 236, 2010 = 250, 2011 = 269.

(different cars, different weather etc)

Thanks for posting that, Calvin! Eitherway you cut it, that '11 GSR put down damn impressive numbers for a stock car.
