My dyno numbers

P's_Z

Ok, so not really related to tuning, but couldnt find where to post(admins please move if necessary, sorry and thanks). Today i did a few baseline runs on my completely stock 2013 Z and here are the results:

270whp
220 tq

I know these are just numbers, and while i feel good about whp, i guess i expected to see a bit higher tq number, what do you guys think?

Runs were made on 4th in a mustang dyno. Humidity was high and Temp was about 92 degrees. I'll try and post the graph later on.

Comments/opinios are welcome

Should be in 5, BUT without a tune, you'll hit the speed limiter

Thats what i was told! But the guys at the dyno said that it'd hit 130 in 5th and their response was basically "at my one risk" and "normally we just do it in 4th "and this and that". They werent being jerks but i guess it was my own fault for being ignorant as this was my first time "dynoing" a car. I guess also trusting them since they do this everyday and just listening to their recommendations. What was cool and did not expect was, that since i wasnt tuning or anything, they let me do 2 of the pulls plus the 1/4 mile simulation. Ive always seen the tuners doing the pulls but obviously because the cars were being tuned

Not saying they don't know their stuff but not everyone knows everything about every car. I'd have no idea my gear ratios if I didn't own this thing. You shoulda asked or really told them, no 5th is the correct gear in this car with this ratio. But no never mind, from now on do the runs in 4th so you have a good baseline to go off of.

Thanks! I could always run a baseline again in 5th this time. I do plan on modding, but probably not for a while, so I think I have some time before then.

synolimit

U will top out in 5th though but everything below 155mph you'll be good on.

Got it! Thanks again.

Just do 2-3 runs in both, that's what I did. And once I was ON the dyno, they didn't care how many runs I did


Also, don't know if PR has one, but use a dynojet

We do! But from what what i was told, they are older versions which are not as accurate as the newer ones. Dont know if this is true, since honestly i know nothing about dynos

DEpointfive0

Oh, I really don't know either, but do a few runs in both gears. Again, once you're ON the machine, the difference in time of 3 pulls and 6 pulls is 5 min? And if the shop knows you'll be coming half decently often, they shouldn't mind. Even if you never come back, they shouldn't mind

Defintely doable! The guys in the shop are pretty cool, including the owner who even gave me a discount since i was doing a baseline and was the first in their shop to do a baseline in a Z(they work on Z's, but mostly work on evos, sti's, mustangs and their specialty.... GTRs!

Jordo!

4th is fine -- less wear and tear on the motor.

Those numbers are in line with expectations, and that particular dyno is calibrated to read close to a dynojet.

EDIT: Correction; the whp figures are close (although on the lower side) but the wtq readings a very low relative to a dynojet.

Hi,

On the mustang dyno, there is a factor that says "HP@50 Miles/hr". May I ask what number is keyed in?

P's_Z

Did not notice, does that appear in the graph or just in the computer screen in the dyno?

I apologize for my noobiness

blumango

You should see it at the bottom of the main screen. Mustang has a list of cars with these figures which the Dyno operator must key in but unfortunately, Mustang stopped updating the list since 2007. Our cars are not listed and that can affect the Dyno figures....
