Any fast cars up here?

What it does do is measure power

You completely missed the point.

You cannot do things at the track, on the street, at the drag strip that you can on the dyno - and ultimately a better use of your time since you can track down and sort out problems there, real time, rather than trying to replicate the same situation. You can do simulated 1/4 mile runs on a mustang dyno (not sure about others) which makes it even more useful.

Yes a dyno "measures power". All a wideband o2 sensor does is "measure a/f ratio". All a datalogging package will do is "measure various data paramters". By that definition, none of them are tools either. The dyno is a tool just like any of those other things.... it is up to the tuner to utilize them effectively. IMHO, as much power as you are making on your car you should spend more time on a loading dyno so your shit doesnt blow up.

uh.....you have to actually make a point before you can say "End of discussion"


Tell us why RJ is wrong.

I already made my point. A dyno measures torque and calculates horsepower.
A dyno does not do anything else.

Without an oxygen sensor a dyno will not tell you your a/f ratio. Without logging software a dyno will not tell your ignition timing advance, or how much knock is being encountered, or what the maf/map sensor is reading or how hard the injectors are working. Fuck...without a hookup to your ignition system a dyno won't even give you torque numbers or the revolutions per minute.

My point is this...a dyno is not a tuning tool, which is what RJ has said several times. All it is is a place to do tuning...you could easily do the same work at the track or on the strip. What it does do is measure power.

i mean you both are right.. its for reading HP and TUNING. if you just wanna throw your car up there and get some hp numbers you can do that. it is also used as a tuning tool, hook up air fuel, take readings. add subtract fuel or timing as needed. simulate real driving by applying load. not many dynos do this. from the million dynos i have watched almost all of them have been people chip tuning their cars and using the load bearing dyno as the devise to get readings. but at a car show or dyno day people are usually just getting HP numbers.

also its hard to tune on a dynojet or mustang dyno or brands like that. you cant apply load and you can only tune full throttle (good for a drag car) thats how inline and all the shops dyno and tune their cars. but once you get out on the street and drive NOT full throttle the car will probably run like ass unless you mash it. seen it a billion times.

so yes a dyno is used to read HP and torque.. but its also a very helpful tuning tool.. i think you guys both agree but just are on different pages

Mustang = Loading dyno

posted my last comment before reading RJ's so i repeated some junks

[Sijray21]

how about this:

you both are right....

definiton of dynamometer: "measures mechanical power" found many places

but the numbers on a dyno don't really matter, only the differences when tuning. No two dyno's will be the same, where the only purpose for a dyno would be to get the maximum output that your engine can achieve. This 'maximum' output is empirical, but the absolute value of that output doesn't matter, just the fact that you have reached the 'maximum'. The top whp and top torque that your car can get is nothing but an unknown variable that a dyno jet will bring you close to knowing. I personally think that the most benefical thing you can get from dyno-ing your car is the power band; knowing where your car makes the most power.

Did i get that right after reading all that?

edit: this was after the first post on page 7, if there is anything contradictory since ignore

[rotorsownyou7]

I live about 45 mintues from Roanoke, in Franklin County.

man, people around there must look at your car like its a spaceship :lol: every time i go through there all i see are trucks and mustangs.

Yeah, that is about all there is.

[rotorsownyou7]

Damn, didn't mean to start some shit. My first thread is huge.

[.RJ]

Everything goes off topic here......

[Sijray21]

Damn, didn't mean to start some shit. My first thread is huge.

read more threads....thread-hijacking is VERY common...we tend to digress a lot from the main topic

main topic discussion: there are some pretty fast cars here, but driving ability is key*...and that's what our focus is as Madison Motorsports

[KPWSerpiente]

Fuck the driver. Cars are the only thing that matter.

That is my new stance.

And rotaries blow up. That is still the heart of my platform.

Gee thanks, Captain obvious, a dyno measures power.
Got any other pearls of wisdom for us?

You can measure your dick all you want, but if you never put it to use, it sure as shit isnt doing you any good.

Using your own definition, dynos in general are useless, because as we all know you take your car to X dyno and it gives you a number. Then you take it to Y dyno, and it gives you another number. Well shit, all of the sudden that "power" number doesnt mean squat! Who knows if its accurate, who knows if its really how much power you have (grr!).
Oh but wait.... what if we use the same dyno, making changes in between each run to see how that affects the power output and area under the curve. *lightbulb* BRILLIANT! And just like our 9th grade science teacher taught us, we are minimizing external variables for a more accurate test!
now instead of swinging our dicks around, bragging to our friends about some number that doesnt mean anything anyway, we can actually improve the performance of the engine! Wait a sec....thats called tuning!

Rotaries blow up? So piston motors don't? Good find.

maybe we can have a dick measuring contest at the car show.
sorry.. for that comment.. must be cause i drive a VW and vws are for gay people hahahahahhahahahahahahaha jk

but yea these threads got off topic fast.. as my sig. says

i wouldn't exactly call that a new stance.

yeah, you'll do fine around here. Welcome! :wink:

[KPWSerpiente]

Thanks for the lecture on 9th grade science Evan.

Now because I remain the only person on this thread who has actually used any kind of data logging sotware, any kind of wideband oxygen sensor, and made any kind of changes to both the fuel and timing maps stored in an ecu and all of this while on a dyno I'll just go ahead and continue to think my way.

But keep talking about dick measurements and about how a dyno is more useful than accurate data logging.

Come on new guy. You're going to have to hit harder than that.

i wouldn't exactly call that a new stance.

Actually Mike...I invited you out to the dragstrip in the past and we can still go anytime you want. We can take turns running my car, or yours. Point being that I expect you to be consistantly slower because of your limited drag experience.

that you are NOT. hahaha speak only for the few people on here you know of..i have done more tuning.. more dynoing..more ecu modding.. more wide band o2 hookups that you times a million hahahaha

know who you are talking about or to before making a retarted statement like that

seriously.. hahaha (shaking my head in shame)

[Dave]

actually, that totally defies your new stance. That is precisely stating that you being the better driver at a drag strip will result in you having the lower time regardless of the vehicle driven. Therefore, it still comes down to the driver, not the car. A slow-ass car driven well can always beat a poorly driven fast car.

you seriously are one cocky mofo. get off you highseat already????

[Dave]

That ECU is not a waste of money, how did you come up with that?

because I'm the type of person that doesn't buy something unless it is necessary.
Somebody else asked earlier what kind of mods you are sporting. I'm not going to waste my time going over to the RX7 forum cuz I don't have enough time of my own, so share and perhaps I'll retract my statement of "needing" that ECU to support those mods .
