Any fast cars up here?

[Sijray21]

As much as it turns me on to hear a 1000+hp supra, I hate dyno queen supra's. I would much rather have 500-600usable horsepower than 1000+ unusable horsepower.

as demonstrated in GT4 without traction control....spinning out through 4th gear and you're still last in the pack

such a true comment

The dyno is a tuning tool - the peak numbers are pretty useless except if you want to boast about how big your dick is.

A wideband oxygen sensor is a tuning tool.

A dyno is a device that measures horsepower. If that reading is off in any way the the measurement is no good.

it's all relative though, right? i mean, regardless if it's not totally on the money, at least you can use it to change settings.

if thats the case then what brand dyno is accurate... is there even one in america???? hahahaha i just know this cause when we dyno shopping there was only 1 dyno brand in america that the tuners in europe would tune with, and everything else is wrong. you cant buy any of the good dyno's in america

What kind of dyno was it?

[BLAIR]

superflow... wont find them many places cause they are about 2 times the cost of a regular dyno

[rotorsownyou7]

And for what it is worth....a manual swap would have been simpler and more effective than switching over to a standalone unless you are running some crazy set up that you didn't feel like telling us about.

Naa, not too crazy, just running low boost as of now. I will need that ECU soon though.

[rotorsownyou7]

so in essence, it would have cost you $2000 and the couple days that you spent becoming more intimate with your car would have been appreciated even more every time you shifted that gear. Wasted your money on that big bad ECU.

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

[rotorsownyou7]

eh, a little advertising and we'd have no problem...dyno's around here are few and far between...i live in roanoke,a nd the closest ones were in richmond and NC

its not just the money. imagine the noise of up to, and possibly over, 20 cars (whose mufflers may be questionable) taking their engine to redline over and over. the people in the dorms next door will go on a rampage.


btw, i didn't know you're from roanoke. i am too, i live near cave spring...but i'm not a yuppie asshole 8)

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

I would like to come to this car show, but I already had planned to go to Nopi with some friends. Do you guys have these things a lot?

once a year, in april. forget nopi, come chill with us and enter your car!

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.

Wrong.

Dyno = tuning tool. You use it to measure HP as an end result yes, but the deltas are what matter in your tuning - no matter what brand of dyno it is (although a loading dyno is better, IMHO).

If all you want is numbers to put a sheet on your windshield and say "hey guys look how big my dick is" then more power to you - spin the rollers on a dynojet and call it a day.

[KPWSerpiente]

Holy shit RJ. You're just wrong. Get over it.

End of discussion unless you want to try and tell us why a dyno that measures power at the hub is better than a dyno that measures power at the wheel.

Whatever you're smoking, please pass it over

If you're just using the dyno to get numbers I say you are wasting your time. The numbers themselves do not mean anything - the deltas between what you had before and what you ended up with are whats important, especially with tuning. The A/F ratio doesnt matter as much since you cannot always tune to a specific ratio - there are too many variables. The dyno will show changes in the A/F ratio along with changes in torque and you can look at how much ignition the ecu is pulling out (knock). Again - just a tool, a part of the big picture. Use the tool to get the desired results - reduction in lap times, ET's at the strip, driveability, and so forth. Generating "xxx HP" on the rollers doesnt say jack chit about the state of tune or how well the motor will do. Thats why I said if thats all you're looking for then load it up on a dyno jet and spin the rollers - a calibrated dyno jet seems to be the de facto standard when talking about peak numbers.

IMHO, a loading (as opposed to interia) dyno is a more accurate tuning tool because it gives you more options when tuning. Want to tune low rpm, heat soaked, high load where knock loves to hide in the timing maps?

you know your shit about dynos..

I dont know shit

I just ask questions and listen attentively to those that do...

well then..... what you stated was completely accurate

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.
