Put my 2007 G35S 6MT on the dyno for the first time today. Pulled 241hp/206tq these numbers seem a bit low to me but the car is also bone stock. The dyno was just installed last weekend so it may not be completely calibrated. Just wondering if these numbers sound right, horsepower seems to be in the ball park but torque seems to be very low to me. Would love some input, thanks.

 

All dynos are not the same. Mustang dynos e.g., tend to report lower than others. And were the numbers adjusted to standard day conditions? Differences in conditions from standard day (59ºF, 29.92 in/Hg [sea level], humidity is buried in the condition viscosity) will yield different numbers. Even tire pressures will affect dyno output.

All that said, your numbers are within reason. Multiply the numbers by 13-15% (drive train losses) and they should be pretty close to Nissan's quoted power for the VQ35.

 

What's your altitude? Where I live we lose around 10% of power due to lower air density.

 

No where near anything that would affect power loss haha. I live about 20 miles from Nashville, Tn.

 

Those wheels are definitely not doing you any good:

Shed some weight off the ride and you'll see a vast improvement...wheels/brakes/shaft

 

That's another thing I was thinking about. 20" Vossens look good but they aren't helping me out on the performance side of things lol.

 

Nashville is at 600 foot altitude above sea level. You take a 3-5% hit just from lowered air density compared to standard day conditions. If you can give me temperature, barometric pressure and humidity at the time of your runs, I can be more exact. Between your altitude and drivetrain losses, you should be right close to expected power.
