its possible that a car get better results in a mustandgyne than a dynojet???!!!
 

I was in a mustangdyne today and my carr leaves the dyno with 286whp and then in the night goes to a dynojet to see the difference and in the dynojet the Z gives 279whp wtffff I am very frustrated!!!! Can you guys please tell me why that could happens?

... Did it get 500 times more humid?
We're there any other differences?

If at the dynojet you didn't have any fans, the engine could've pulled timing... I don't know how much it retards it and how much power you'd lose

They dont have any fans in the dynojet but in the mustang they have 2

It's really hard to compare results between two dynos. It really depends on how they've got the dyno set up. There's a lot of settings that can be tweaked between different types of dynos, or even two of the same type. Don't get too worked up over the 7 whp difference between the two. That's a 2% variance. The fans might have cost you 7 whp as well. Personally, I'd pick one shop to do all the dyno runs and stick with it. It's still going to have some variance, but not what you would see switching from one to another.

But normally a dynojet have a difference of 10-12% of mustangyno....im frudtrated because I have some mods on my ride and I have seen many guys here with mods like me and they got 320 whp in a dynojet

320 whp on A dynojet, or THAT dynojet? Again, it all depends on how the dyno's set up. You're correct in that dynojets usually read higher than mustangs, but one or both of the dynos you used may be calibrated differently from the norm. Don't sweat it too much. The number doesn't really mean too much. Stick to one specific dyno, and look at the changes before and after mods. Or, take it to the track. Trap speeds don't lie.

Dynojet dyno's don't have calibrations outside of SAE and STD correction which is prefixed into the dyno and based on the weather. (if they have a weather station connected to the dyno) Other dynos, like mustang, dyno dynamics, land and sea, etc. can be altered by the operator to inflate or deflate numbers. Most unaltered mustang dyno's read lower than dynojets. If I had to guess, the one you went on has been adjusted.

Guys, he said the Mustang dyno had ventilation and the Dynojet didn't. That's all you need to hear.

OP- Any shop running your car on a dyno without proper cooling fans in place probably isn't a shop you should be doing business with. Putting your car under that kind of load without ample cooling fans being present can be very bad for the engine. Coolant temps can sky rocket with just the tiny (comparatively) on-board fans to pull air through the radiator.

They (the on-board fans) are intended to keep the car cool at idle, sitting in traffic, and to augment the normal airflow through the bumper at speed, not to cool the car under 100% load while standing still.

also you are in humid hot PR. numbers down there wont be the same as numbers elsewhere.

Also on top of not having fans other determining factors: oil temp (as said car can be pulling timing), altitude, humidity, ambient temp, those are a few and popular factors tjat can and will effect a car. For example I live 50 miles from work but according to my gps my work site is 60ft below sea level and my apartment location is 1700ft above sea level. That will make a difference. Hope this helps.

Yes.

Mustang dynos, and all load holding dynos, can be tweaked to read either high or low (or nearly the same) relative to dynojets.

Throw in different ambient/transient conditions, correction factors, etc. -- yes, absolutely.

So I shouldn't think my ride is a pussy?

It is a well known fact that 370z's are comparatively slow.

I don't think I'd ever call them slow. can they compete with a challenger with 470hp racing from 70-120 or a camaro SS, probably not, but 0-60 stock 370z against those is still a close race and not losing by much at all. in my opinion at least.

What the fúck are you talking about???

Please, reread Sh0velman's reply...

You ran your car on a dyno at about 120+MPH without any fans... Your car is not a pussy, you just shouldn't drive one if you have not a clue how cars work, or you're ok with dynoing your car without ventilation...

Your going to need more than the mods listed to make 320 on any Dynojet. Regardless, what are your stock numbers? The difference between the two is what matters.

Depending on elevation/weather you could come close with those mods. The motordyne manifold will limit peak numbers though.

But I agree that only the delta of the before and after runs really matter.

OP's dyno didn't even go to 7500RPM, lol

Lol.... also guys.... can someone tell me why in the mustang dyne the pass was a long pass and in the dynojet was a super fast pass? The mustangdyne have two rolls and the dynojet have one.... sorry for the questions but I want to learn im a ******* noob

Oh gawd, find a different shop to dyno.

... You need to run the dyno in the correct gear... You can tell them what gear to run... (You're looking for 5th gear)

Please use the search feature and look for the correct parameters to run a dyno


Again, I still am hung up on the dynojet didn't have fans...
How ghetto is Puerto Rico??? They can 30-50k machine but not a $100 floor drying fan?!?!?!

Lol looks the difference between both dynos

Also in the dynojet to put the car in the dyne they have to use wood tables wtf....I only get the car to these dynojet to check the difference in nunbers but I saw its a junk dyno :/

The nustang dyno its a finest dyno one of the bests here in PR these day they have in the dyno 7 GTRs, 1 supra , 3 evo x , and one rally art

Just because they have that many cars doesn't mean díck


Honestly, like SSfirehawk mentioned in your last thread, you're looking for the DIFFERENCE in your numbers between mods



Again, for the love of god, do not run your car on any dyno again without fans... You definitely took a toll on your engine doing that (at least the car pulls timing to prevent too much damage)

Thanks man

If you run in 4th gear, use 4th in your comparison, likewise if you ran in 5th. They used wood ramps most likely because your car is too low. Also, what is the correction factor used for the dynojet? Was it the same as the Mustang dyno? No fan will murder numbers. The heat will do the same as well. Don't get caught up in a numbers game. You will forever be unhappy. Look at me... I got mad and now I'm blowing $hit tons of money on a supercharger... or two. Try and gather as much information with your runs, note all the differences and post.

My guess is dynojet ran in 4th, not 5th, no fan, correction factor was different, and ambient temps went up because dynojet was done later. A culmination of two or more of these can and most likely cause the low numbers.

Listen to logic!

Yes he is, SS got butthurt with my numbers, he even put a hit out on me!!!
Lol

I know where you sleep. You have a Vanilla Ice sleeping bag you still use from the 90's

Wait, that's me, nvm...

AHAHAHAHAHAHAHAHAHA!!! Thanks for that brother

You recommend to run in 4th or in 5th on the dyno?

5th is preferred.
