Xcede N54 S/W only dyno record

[Sherwin@xcede]

Didn't get a chance to post this what with being so busy of late, but this is our record for an N54 at our dyno in Edenvale. This dyno reads pretty much exactly the same as Snail but I'm not comparing to other tuners, or other dyno's so please no politics. This is our internal record as we have done over 20 on this dyno. This car has no hardware, software only. It was flashed on the dyno then a few runs were done. Dyno room got pretty darn hot after a few runs as it's a closed dyno room. It's a manual & makes bit mid-range so there was slight wheelspin on the rollers around 4000rpm. Can be seen on the dyno. Have to get someone to sit in the boot to eliminate the wheelspin.

Can you please explain to me why there are such big differences with cars that are flashed?
You always achieve great numbers with these cars, +50kw on sw only is amazing, but why are there such big gap between different cars? Is it the way your tuning has evolved, or do you just get wednesday cars, as sometimes the differences are 20 - 25 kw and that is a lot.
I know different cars make different numbers but sometimes these differences are very big and I don't understand why!
If you or anyone please explain it to me as I don't know much.
Anyway those are fantastic numbers, car must be a animal, great work guys!!!

use photobucket i dont see anything

Is that the lowscore record? 1 frogpower is not very strong IMO, especially not one in an ice cube...

 

[UpNcOmiNg!]

Cant you see how the front is pulling up and how it squats even on the dyno (new name for ice cube!!!)
Its obvious its a high score! psh

Never mind horse power when you have frog power! Think I might know what this record is though..

Guys any info regarding my previous post here?

no mercy, i am very curious to the answer to your question.

and it seems there are no takers to that question, i wonder why:mmm:

I think in some cases its a matter of what boost the car runs. Whats safe for some is not for others.

 

[nomercy]

George I understand what you are saying but who decides what is save, if you tune your car with a company, you put trust in what they are doing to your car and most people will chose the saver option, but what I don't understand is that if it is boost related like you say ( more boost more power ) certainly their is a limit of what a stock car can do, so why the big differences in the end results! 10-15percent I can understand dew to many factors but I've seen 30kw differences and don't know why...?
If its the tuning that is evolving certainly all the old customers would want the newer "software" as they paid the same amount and what the same results, within reason!

Well done! Serious gains! But why is there a difference in the ambient correction between the two runs? That willl give you false readings!

I'm still seeing an image of a frog and msg "domain unregistered", can you see the dyno graph?

 

[Kisho135i]

On stock cars the should be a boost limit to ensure safety of components, i dont see or understand how its safe for some stock cars and not safe for others:thinking:

Lowest we ever got was 35kw on the wheels, & the highest was 57kw. The average is around 40-45kw.

Funny thing is the boost on the 35kw & 57kw maps were the same. IT was merely the car's ability to maintain power to high revs.

The cars made similar power & torque in the mid. Some cars drop off earlier & make less peak power. It's all to do with the timing up top when the boost drops off & the other tuning tweaks we do. But sometimes it's just hardware variances. Some cars have carbon buildup & peak earlier, etc.

Sherwin.... Why is there a difference in the ambient correction between the two runs??

 

[Sherwin@xcede]

Sherwin.... Why is there a difference in the ambient correction between the two runs??

The difference in ambients is because *suprise* *surprise* the ambients changed between runs.

Our dyno team is meticulous about entering the exact ambient settings on every run. Baracus & a few other guys have been in there & watched the exact procedure we use.

The dyno is a closed room with no extractor fan yet. So every run we make the temp goes up 3-4 deg. Not to mention the humidity, etc. Also the room gets filled with exhaust gas with as you know has the oxygen component already depleted. So a room full of useless, hot air, getting hotter on every run.

Not to mention the fact that the car was chipped on the dyno. I had to make the file for the car which took a while.

But yeah, back to your question. We are using an ambient-corrected dyno the way it was designed to be used by entering the ambient conditions on each run & that results in a higher correction in that closed dyno room on the 5th run.

 

[STREETRACER]

I'm not dissing your run! Just ambient correction is a big load of crap!
Get the car on the same conditions 1st run 26% ambient I guarantee you that you will not see the same figures.. The only way to measure power at the coast is at the coast! Firstly no N/A car will gain 29% to the coast never the less a turbo car! I understand apples with apples but my opinion comparison runs must be taken on same dyno settings before and after to measure accurate gains. Just my two cents either way you had a great gain there its only a 3% difference in setting but I was just wondered why the change in settings!

 

[Sherwin@xcede]

I disagree. It is 100% essential & SAE or STD correction is used all over the world.

Get the car on the same conditions 1st run 26% ambient I guarantee you that you will not see the same figures

Already did that & our findings in our dyno room seem to be different to yours. We ran another car & did many runs & the temps & hence correction went up. Then we unstrapped the car & the owner went for a drive. He came back & we re-ran it in a fresh cooler dyno room with meant the original CF. IT made more power. I'll take fresh cool air over high correction anytime. Especally for a turbo car. & 3% correction is like 5kw anyway.

For someone that reports to know so much about tuning you really are a bit clueless when it comes to Dyno's arent you ?

The correction factor is not there to correct to SEA/COAST level, it is used to correct to a SAE standard.

Here is some info for you

For dudes who dont know much about CF's and dyno's

Expert from that site

We have all seen and made claims of an engine’s horsepower. However, this stated horsepower is almost never what the engine actually made for power. How can that be? Most of the stated horsepower numbers are “Corrected” values. The correction standards were developed to discount the observed horsepower readings taken at different locations and weather conditions. It is obvious that an engine builder in Colorado could not produce as much horsepower as a shop at sea level. There is just less oxygen for the engine to burn at the higher altitude. What are less obvious are the other weather condition effects on the engine. So in order to compensate for this all advertised horsepower is “corrected” to several different industry standards.

Most of you know about Atmospheric Correction Factors that are used to compare an engines power output for one day or location to another. However, these factors can be rather confusing and even deceptive. Everybody seems to declare there engine’s horsepower as “etched in stone” number, however we also know that the engine will make very different power on different days. Excluding other factors like engine temperature and quality of fuel used, the engine output is very dependant on the amount of oxygen in the air. So the only way to compare an engine’s horsepower is to correct the output on a given day to some standard.

The most common are the SAE standards.
