Jay's Tech Tips #49: How To Read Dyno Graphs. (Explained)

[@crxkid16]

Thanks Jay. Just a wealth of information. Helping further educated the community as a whole one video at a time. I appreciate your service!

[@boosted2.4_sky]

Excellent information Jay!... People want to learn...it's awesome that you're willing to teach...🏁

[@realstreetperformance]

Thank you Craig!

[@SRDmotorsports]

Love this!

[@SRDmotorsports]

On my latest, I did talk about dynosheets specifically dynojet and referenced this video cuz Jay explained ALOT of good things to know or worth knowing to understand the dyno and not get “awed” by online posts lol

[@ricepony33]

Well done Jay, thank you.

[@realstreetperformance]

Thanks Andre!

[@kawi-boii]

Hey I met you at Tulsa race way park. Mopar and rotory tattoo….. I’m finally watching dude. Pretty dope.

[@Spudstrodamus]

Always something to learn from your videos.

[@realstreetperformance]

Thanks for the support James

[@DJNADJIBBeatz]

Thank You Very Much Jay very great explanation, I love the educational videos. more 2JZ teardown please.

[@realstreetperformance]

Sure thing, will do

[@SRDmotorsports]

Jay… I hope you don’t mind if I mention this video on one of the videos I’m making as I will talk about dynosheets, and I think the best way is mention you guys and give a “card” link to this video so they can jump to this after As you explain a lot of good stuff including the “uncorrected” factors and if it’s cold it’s gravy 😂

[@drewmurray2583]

Awesome tips, thanks! I used to run an older MD-750 and have always wanted one of my own. In the next few weeks I will be building a dyno from scrapyard junk!

[@realstreetperformance]

Thanks drew. Good luck

I definitely enjoy this type of videos. This is great information. Thanks Jay! 👍 🍻

[@realstreetperformance]

Thanks Omar!

[@GARGOLASPERFORMANCECOATINGS]

Great video, I've been around cars long time and this gives a deeper insight that you don't see on dyno graphs all the time , thanks for the explanation 👍🏾 great vid !

[@realstreetperformance]

Thanks Raul!

[@MrTDM09]

Excellent Jay! 🤙🏾🤙🏾🤙🏾

[@realstreetperformance]

Thank you

[@shadleybam3140]

This is probably one of the best videos on this topic. Could you do another video on a high powered NA car and showing different tire size or even tire compound and how it will affect numbers

[@admintuning]

Awesome video. Well done! Lol @ the excessive smoothing of the eddy brake dyno.

[@90slegends49]

Thank you Jay love those educational videos

[@realstreetperformance]

stay tuned, more to come!

[@johntosh6146]

Nice explanation Jay Good to hear someone actually not using smoothing in the software. I have always preferred a wider torque spread than overall peak HP as the tend to be more reliable and just as quick if not quicker in certain conditions

[@realstreetperformance]

Thanks for joining the conversation

[@PeakPerformanceReviews]

Awesome video Jay, so so well explained ✅👌

[@realstreetperformance]

Thank you!

[@PeakPerformanceReviews]

@@realstreetperformance welcome guys ❤️🙌

[@notone4029]

Thanks for making video. 👍🏻👍🏻👍🏻👍🏻

[@asm9186]

awesome video

[@RolanTHUNDER]

Very informative and helpful. Thanks Jay! I road tune my supercharged S2000 so that smoothing factor in particular plays a big role in final numbers. The smoothing has to be pretty high for the data to be usable but that lowers the HP and torque figures a lot. Virtual Dyno is a great tool for this if you don't have access to a dyno.

[@dsmubz]

Thanks a lot 🙏, I just installed a brand new 224xlc dynojet at my shop with eddy brake control, im even more excited to start doing runs.

[@bruceh5759]

Great info

[@realstreetperformance]

Thanks Bruce

[@mrhyspeed8769]

Thanks again J! Great Insight on dyno world.

[@nedudki]

Moooooooooooooore like this! Awesome, thank you!

[@realstreetperformance]

On it! Thanks Chris

[@BassInterrogation]

Awesome as always 😁

[@realstreetperformance]

Thanks Tom!

[@panagiwtisn13]

Fantastic video, thank you!

[@SPTuning]

Very nice explanation on the different dyno settings and their advantages 🙌🙌

[@octanetvguys6856]

Great info to have Thank you 😀

[@tropicalspeedbmw]

Great video. Thanks for breaking it down to bite size pieces. Do you or can you explain a turbo graph?

[@markrich3271]

I know in the world of diesels we use eddy brake dynos. We are not able to get full boost on inertia dyno. That in turn won't show what the engine really makes. We have such a short amount of run time like my truck is done at 3400rpm We need full load on the the engine.

[@PhillipTieuChainz]

Can you put up a video on how to read a turbo compressor map and how to compare based on engine?

[@action76news]

Hey jay can you explain how a dyno graph will look when the AFR dips rich or goes lean and how that correlates to peaks and valleys on the torque and horsepower curves, like if there is a dip in torque during a wot pull if you look at the AFR it too has a dip or rise vice versa can you touch on that please?

[@Freak8xxx]

Thank you 🙏

[@realstreetperformance]

Thank you!

[@bobeskob]

So what about the performce that manufacturers claim? For example Golf 8r has acording to dáta sheets 320 horses. Are those corrected numbers or u corrected?

[@ianzwezerijnen6043]

I had my car on an inertia dyno/dyno jet recently (CF sae Smoothing 0). It did spin with mickey thompson et street r so they put some sticky stuff on it. My question is on the dyno graph is says the power it made at Engine RPM. Is that the actual power to the wheels or engine power?

[@eefmydee1slideways]

Baller af

[@itsjussjerry]

Jay, anyone else tell you that you and Brian Spiker from TransLab sound ALOT alike? Lol. I spoke with him on the phone a few days ago and could’ve swore it was you.

[@Procharged32]

Is horsepower figures always higher than toque.

[@hisheighnessthesupremebeing]

X marks the spot 5252 (old imperial units)

[@ehworkshop9922]

My hundyno can detect any problem just like inertia dyno

[@issastock5.3]

What happen when you can’t dyno in 1:1 gear? Or in under drive gear…. Will the dyno read differently?

[@MrGamelover44]

yes,.... of course it will read lower, but doesn't mean the car isn't actually makin more power in the next gear, dyno is just a Tool to see the power it makes and where, 4th gear is best for a 1:1 but most cars dont' make enough power to do a quick pull in 4th, it would be too long of a pull where egts etc would climb too high to see accurately a power run

[@brbntrl2433]

tips on reading plugs for meth?

[@URFIT]

My graph went down what could be problem

[@URFIT]

Its lie a wave

[@URFIT]

My car is a turbo diesel

[@martinrodger9565]

I’m steady state, I’m true braked horsepower; am I a joke to you?! 😂

[@ACommenterOnYouTube]

I want a turbo for my supra, where do i buy ?

[@machgaminginc7898]

[@thomasjanssenthomas8300]

👍👍👍⚓

[@tsdyno]

WOW, either this is missinformation or you're very biased towards your inertia dyno... firstly how can you even tune those "1000" hp cars accurately when the dyno pull is 2seconds long? If you do a 5th gear pull on the highway or even the top end of the 1/4mile it wont go from 3000rpm to 9000 in 2 seconds.... And to say that eddy brake dynos can be manipulated and wont read missfires correctly is bs. It just depends on the dyno, every dyno can be manipulated somehow. And what I have noticed is that when theres not enough load on the dyno, be it inertia or eddy brake, the power numbers are higher. Now this is just my opinion, and probably many others aswell, but from what i've seen dynojet numbers are always hgher and sometimes even impossible for the compressor to produce. When you have a 1000 crank hp rated turbo making 1300whp, just kinda makes you think that maybe its bs numbers. Especially when every other dyno graph with the same turbo is around 800-1000 crank hp :D

[@tsdyno]

Also i know many cases where a car has been dynoed on an inertia dyno AKA not enough load, and theyll make good numbers with high ignition advances etc. And on the few first pulls on the street the engine will detonate and blow up. Also another problem here is that the boost settings are never quite right, youll have to lower the duty alot on the street, not enough load = bad tune. Over boosting and detonation after an inertia dyno tune is very common, atleast where i live. I have many examples of head gaskets blowing or pushing coolant on the first pulls after inertia dyno.
