No you are not understanding and I'm done with this.he dynoed in amazing weather to put down high numbers.it was 57 degrees but his Dyno used a 1.03 correction factor.to get that cf the weather would of needed to be about 103d out.

You see ? His numbers were inflated on top of being in excellent conditions

EXACTLY. 12 pages and one month later no one has done anything to explain that or put us one step closer to proof. Im not a disbeliever that it can happen, Im just a disbeliever when no one can even explain that basic item.
Start there, square one, then proceed.

Not to butt in, but I have seen this countless times by all kinds of dyno operators. I was even told by 1 locally that they will put in different correction factors to give out higher numbers to clients who want to see them. To buy a dyno and maintain it and run it is big money, so if they can get someone to their shop and give them numbers they want to see, they will be going back. Go to a dyno that says XXX and then go to another one that says XXXXX. Most people will go to the one that reads higher every time. It happens to the best shops and the worst. Nelson racing motors is the biggest offender, but that is a whole different story all together.

Maz - werd!


There is an entire market for tunes and dyno sheets for bench racers....... an entire "niche'"...... which is not all bad. People impress other people with all sorts of things.... fashion, dyno sheets, watches, .. its all good.

Let me add just one more thing, and I will get off my soap box. I am not disputing the dyno numbers some are seeing. The correction factor and every perimeter may very well be correct. And the reading you get may seem legit.


But here is the problems with using dynos for solving total HP readings. They are all off.
Let's take Dyno Jet for example. One of the best dynos you can buy. From the factory they WILL be off 2 to 3 percent. Now you have to factor in the 2 biggest things that will derail true readings. Installation of the dyno and operator error.
Installing a dyno is a PITA. And it alone can knock off accuracy of the unit in general without anything else being done. So from the factory you can go from 2 to 3 percent off, to 5 or more percent off.


And then you put in the worst offender of accuracy of them all. The human element. All bets are off after that.
I never once used a dyno for HP numbers. I used it as a tool for improvement, ironing out hiccups in RPM graphs and tuning sessions. "How I can best get 5 more hp at 5k RPM at turn 3 at Laguna Seca".


That's what I wanted a dyno for. Not totality of the numbers game because it's not really meant for that and it's not at all accurate for that. I needed and wanted improvement in a real world scenario and that's what a dyno is for.


Now you guys can tell me to F--k off now.

Dyno = used to measure delta in performance with changes in engine mods... not relative HP.... only changes.


UNLESS you are selling tunes, or selling parts.

I only use one dyno in my area for my cars. It's probably the lowest reading dyno in a radius of 50km, but I couldn't care. The owner is a friend of mine, and the dyno is well looked after.
I don't care about the maximum number. I just want to see the number go up after doing a mod.

skratch77

Did you Dyno the car yet?

Ludedude

^ This. All day long. It's good to establish a baseline then see the relative difference after a mod. That's ALL that matters. The rest is just internet dick measuring.

Is there a rumble in Temecula going down or nah? https://www.sbnation.com/lookit/2014...ht-kobe-bryant Here is the reference for those of you who don't follow NBA or memes religiously

Such a waste, amiright? We could promote the hell outta that card.

skratch77

What happened to the second dyno with all the details?

arun.6ix

I didn't need to re-dyno. Got the information I needed from the first dyno and was provided lots more information on how this was accomplished.

JimGnitecki

i.e. Could not now reproduce the unicorn result?

skratch77

Oh so basically the runs were bull ****!

I mean you were the one who said you made appointments to re Dyno not us lol.

I wonder what that secret prototype tuning was? Hair dryer on the Dyno sensor?

I haven't posted up because real st is booked, but when i go back please trust i will post the files up with all run conditions and bla bla, and then when i post better than 120.5 a lot of people will find something else to question or complain about. how does that saying go "he who laughs last" or something like that

604 C63

No idea why all you guys are such skeptics, you should really be busy wiping all that egg off your face and eating crow.

arun.6ix

Yeah I did say all that, what's your point? There was no need to re-run it. I thought there was and after the owner showed me dozens and dozens of the same pulls from different cars with the same power output it was good enough for me. It's so funny you are quoting me, but they got like 50 calls asking for the same tune. Please call them and get it but until then
let me pretend to have 500whp with my so called unicorn, my factory freak I'm good with that. You guys have fun at Atco.

arun.6ix

Bro don't post anything, I have the details but I'm over this **** show with certain people here. They will still find a way to criticize and put you down. If they really want to find out, they can go pay $1100 for the tune and $300 for before and after dyno to get what they want. Then they can sit there and argue with whomever it is that "the dyno pull was adjusted to the their favour."

I am Jeff

It's funny how you posted some unicorn numbers without any supporting dyno information, yet you expected the forum community to praise you on your magical numbers. Let me get this out of the way, your baseline numbers (pre-tune) is extremely inflated. You volunteered to get have your unicorn results re-dyno'd, but backed out after you received some "secretive" dyno operator information.

So yes, we're calling BS on your inflated baseline numbers, which directly leads to inflated inaccurate dyno results.

skratch77

Then why is it so hard to post an uncorrected Dyno sheet or one with the run conditions on it?

arun.6ix

Cool Bro thanks for the information.
