Check my Dyno results, seems LOW?
Went to a tuner here in Australia for their Dyno Day, and to see and try out my first ever Dyno run!
My 2015 7AT Z is bone stock besides the wheels and springs, has 21K miles on it, and I think my results seem much lower than what I was expecting: https://s6.postimg.org/q4azpnsep/20170819_190440.jpg I only went to try out the Dyno because the Dyno day was cheap and I wanted to see what my Z does before I throw on the AAM TT kit. The above Dyno is a Mainline Dyno which apparantly reads 15-18% than most other popular Dynos here in Australia. But I am not sure on this as I am completely new to the dyno tuning world. So that 173.1 kw is around 232 HP +~18% = 204 kw (273whp)? The tester said my Z felt very torque'y, it just wanted to go when ever he touched the pedal. What do you guys think? |
Bossman; You're getting dyno'd in the wrong trans. gear...it say's 3rd.
that's a 2.04:1 ratio....not even close to a true 1:1. 4th gear is 1.41:1 vs. 1.27:1 for stick-shift Z's. 5th is 1:1 in both.....most tuner's do 4th because of the speed;as in a base w/3.357 diff,that's still just over 120mph. That's what is throwing you a curve....i'll dig mine up with a 4th & 5th gear pull. K&N drop in air filter's is only mod at this time. |

Anyways, I will message them tomorrow to let them know. |
Your 273whp guess is actually close to normal for a stock Z and looks like he stopped at 6500rpm. There's another 1000rpm left on the table!

But also, just because there is another 1000 rpm left to Redline, does that mean I will see more power? Are all dyno pulls done to Redline? |
Interesting... your A/F ratio is identical to mine.
I think that fuel curve is too rich to get great dyno numbers. Notice how Hammond is running right at 12, you and I are both at 11.5. I expect mine to be about 12.5 after a tune. |

The 5Th gear pull was to till the speed limiter kicked in @156mph |
Mine is tuned at 13:1AFR wot.

Now I feel like my results are a bit of waste because it was not done complete and properly? |
They probbly know this. They just want to play it safe and not hurt your engine.

When i was tuned @Z1 Motorsports after all my bolt-on's...it was twisted to 7800 in 4th, they wouldn't do a 1:1 5th gear pull because speed limiter is removed & will pin the needle in the corner. Their Dyno doesn't support speeds above 170mph.....that was the info. i was given. |
And by my Tuned graph w/cai,tp's,tdx exhaust....No ported intakes or headers...the power curve was till around 7250 before it turned downward.

Ok shadow85; I thought you were boosted; as I'm thinking your AFR will probably be tuned a bit richer than N/A.
Here's my last printout I have before my updated CAI. This was a 4th gear pull.https://uploads.tapatalk-cdn.com/201...3f2728ea34.jpg Sent from my iPhone using Tapatalk |
