Midnight Hour

I'm looking HIGHLY into getting a 350z Enthusiast and Nissan is claiming 280hp. MOST chassis dyno's are reading 220-230RWHP stock. Where did all that HP go? I mean, the car comes with a carbon-fiber drive-shaft, so not too much should be lost there. Is the tranny just that inefficient? Nissan has been called out a few times recently for bogus HP claims and I'm just wondering if this is just another bogus claim. Any insite would be helpful.

actually its 287hp, and dynos have been reading between 235 and 245. take 240 as average and you get 16% loss. not bad for a rwd car.

My 6-speed dynoed 235.6rwhp, which would equate to approx 280 using 16% loss. So assume the engine picks up 5-10hp after 5000 miles or so (1700 right now), it would be pretty damn close to 287. I think it's rated right on.

also, be careful to read the dyno reports carefully... many shops with dynos are running Zs in the wrong gear to get accurate reading.

I think most who have done it correctly are yielding around 240hp. As ares said, that's only 16% drivetrain loss... not bad at all.

so what did you plan on doing with the extra 5-10 hp?

I planned on having a party!

Seriously though, I must have mis-read somewhere along the way. I thought the dyno's were reading lower than that and were closer to 21-23% loss. Maybe I just read a couple of automatic dynos? Who knows. Sorry for the mix up.
