Having dyno tested a half dozen VQ37's in the G37, I would expect the same 250whp bone stock on our dyno. With some bolt on mods, an easy 270-280whp.....or over 300whp on a typical dynojet. This engine is a top end monster, and loves to rev. It makes power nearly all the way to redline.
Here is our baseline VQ37 bone stock...50 miles on the odometer, if I recall correctly.
