DDMotorsports Shop 370Z Baseline Dyno - UGLY Torque Curve
Took the shop 370Z down to get a baseline dyno while it is still stock. Numbers are 285.46whp and 243.40wtq (ignore the max torque number on the chart as it is inflated due to spikes).
Anyways, I was just as shocked as you probably are to see such an ugly and scary torque curve. This car is 100% stock and I am hoping that its just a bad batch of gas.

Yikes!!! Tune tune tune!!!!

That doesn't seem right. How is the HP curve so smooth if the Tq curve is so jagged? Considering HP is just a calculation of Tq?

^^^ Yes.

They had a 750whp Mustang on the dyno right before me and it was reading just fine. Go figure...
|
Something is not right, I've never seen one like that.:icon14:
435 torque, yeaaaaa! |
ya I say sensor glitch in your dyno. The curve looks right if you through out the spikes.
|
I also don't see how the HP could be so steady while the torque jumped all over the place like that.
On a dynojet from another thread.. http://www.z1motorsports.com/imageGa...line.sized.jpg Numbers are close if you leave ou the spikes on yours. |
Tooooooo ugly to be right
|
I'm gonna go ahead and say something's not right with that curve......
re dyno? |
Nice numbers :tup:. But as many suggested, redyno it. Run a full tank of 93 premium and then dyno may be? BTW, your 370Z is the best looking out of all (injected and GTM). I am a biggest Silver fanboi. Silver > ALL > White > Yellow.
When can we expect a video? :excited: |
Nothing is wrong with the car. What needs fixing is the dyno (most likely a software issue)
|
Through some VP16 in that bad boy!! :tup:

Agreed Skaterbasist, the dyno itself looks to been erroring. I would have expected several pulls to be overlaid to show tolerance instead of one magic pull [or in this case, poor data pull]. If we ignore the spikes in the data, the torque curve looks fantastic; ruler flat and very good numbers in regard to rated engine output.
--->DDM; do you have the rest of the pulls that you did? Also, if that's not your dyno, they owe you clean error-free pulls! Also, did you do any datalogging to observe engine operation beyond roller numbers? Ignition timing, MAF, AFR, EGT, IAT, ECT, etc.? |
