I was curious on what was the stock wheel horse power on a 2007 350z (HR model)danny

306 HP

I am assuming you mean RWHP or actual HP at the rear wheels. The factory does not give this as it varies slightly from one car to another and can only be shown accurately by useing a dyno. (Its also a lower number and would not look as impressive!) And even then, each dyno machine will vary slightly on the same car, along with different elevations and ambient air conditions. In general there is around 15% loss of HP from the flywheel to the wheels due to power loss of operating the drive train, especially in automatic transmissions. The factory numbers for all new cars are measured at the flywheel.

I saw a '07 G35 sedan dyno showing mid-high 280's at the wheels. I have yet seen a Z with the HR do a dyno

I would be interested to see the standard de and hr done at the same time and place, get a real reading of the improvement, and keep in mind all dyno's should be the same but they are not! I've seen stock 350's turn 240whp on a dynapack only to pull 225whp on a mustang dyno, and gine the sae ratings formula change I'd expect the hr's to be in the 260-280 whp range
