OK... Then those numbers make sense.

No, you (along with a majority of car enthusiast) just don't seem to understand how dyno's work

258 whp is great for a Dyno Dynamics aka "The Heart Breaker"

G37's and 370Z's make the same numbers... they have the same engine to begin with.

Only lower one I can think of is a Mustang Dyno (iirc).

In terms of output, this is what the typical order usually looks like:

Dynapacks <-- Dynojets <-- Dyno Dynamics <-- Mustang Dyno

Ofcourse, this can always very since calibration might be to one extreme in a few cases.

They must be hiding a JDM sticker somewhere around the engine bay

This comes out to 22% drivetrain lose? I always thought the rull of thumb was 15%. Is this because of low TQ or the IRS?

Read post 7, 18, and 20...

Interesting. I'll get a few dyno pulls done at HMS and post the results as soon as mine is broken in.

The AFR's are a whiff rich for N/A. The chart shows mainly in the upper 11's:1, which would be perfect for a boosted port injected engine, but perhaps a tiny bit too rich for N/A. Taking into account E10 we all run, 12.7:1 to 12.3:1 should yield peak torque.

Thanks for posting the video and tidbits!

This Dyno is pointless. Its the only dyno of its kind the puts down such low numbers. Not even a mustang dyno will give numbers like that. There are numerous dynos showing the Z putting down almost 290whp, that is consistant to what the crank 332hp is putting out. If the Z was a 332hp car that only put down 250whp then the Z would 80+ hp to drivetrain loss and that is not the reality.

LiquidZ · 01-24-2009, 11:32 AM

Man, I love that color.

Great sound!

o but so wrong you are

see the thing is this dyno dynamics and mustang dyno's are 'loaded' dyno
they simulate the weight of having to move the car also!
so when you on a dyno jet and get your 290whp, thats just how much you can make to the wheels
when you make that power on a loaded dyno thats the power you actually HAVE moving the car.
also they are alot better for tuning because they simulate actual load on the motor and drivetrain better, providing more accurate tuning

+1

Both of these are excellent when it comes to tuning. If I could, I would only get tuned on these. It may read lower, but I don't care about numbers; I care about accuracy, consistency and real usable power.
