Looking for Torque-Hp-Rpm curves

driverace · 5th March 2010, 19:47

I was trying to find a few Performance curves of stock cars. I saw a few curves as posted by GTO and other analysts here at tbhp, and others I found were international ones only!
As owners of cars, we can get the performance data & curves from OEMs, right?
Are the stock car charts published, or any source of that?

Actually my motive is:

1. To study the upper hand of K-series cars (?) Vs older couterparts (particularly, as many here say, IRDe is better than Kappa -for i10) (Mine's a Kappa) :gulp:
If so many claim that way, its got some bite, but again simple-logic tells me K should be better than the old ones!

2. Study basic characteristics of similar cars where engines are more-less the same! like 1.2 K versions here !

Care.

Nobody yet seen any curves ?
I am also searching!
The Hyundai guy says, that would be confidential!
I mean, if they have sold the car, I can take it to a dyno and check it anyway!
And, with any other technical device/machine, its characteristics/figures are distributed in charted formats, so nothing unusual there, (I think!) (pumps, motors, etc.)

Still, some light on this please

Care.

Excellent idea Ace. Id also like to have the performance graphs of stock cars.

Plus, it would be a great help to compare:
1 - Like you said, different engines offered as OEM by manufacturers
2 - If your car crazy, then you can compare the differences after every modification

Have no idea where we can get these graphs but hope people who know spot this thread.

Driverace,

Donno if you've seen these threads yet. They are a start :

OHC Vtec on Dyno

KS Motorsports Dyno Graphs (KS Motorsport Dyno Graphs !!!)

And if you want to do it yourself :
Use your iPhone as a dyno

More to come

Well, I had the small query in mind. and I knew about dyno testing from NFS UG2 ( As I have done a lot of Dyno testing like approx, 30-40% of game time I spent there, and then testing and retuning!), but, it never occurred to me I could do the same here in real life, I mean

But GTOs thread, gave me the push to search for the stock curves, (his thread was about Vtec going on the dyno) so, I thought of starting this general Curve-Archive!
but

Q:01: Why don't OEMs supply us with the same!!
Q:02: Where to get the stock curves for Indian cars (to start with.) like, I saw a Corvette forum where they have the stock curves for all the variants !! even more curves and figures for slight changes under/around the hood!! ( I know, speaking of Corvette is larger in any sense, but still..)

The iphone DIY is interesting!

Waiting for more..

Care.

For comparison the graphs supplied by manufacturers are quite useless.

There is so many varying factors.

The only use the graphs are when made for the purpose the car is being used for.

@CPH !
Well, First, I am trying to search the graphs by Manufacturers ! (not got them yet,) If you have them, kindly share the source please ! (you said

Well, Sure, there are so many varying factors..
When Manufacturer#01 says 80bhp@5500 rpm and
Manufacturer #02 says 70bhp@3000rpm !
we need to see the graphs, the utility rpm zone, and rest of the things, but, surely We can say Peaking_out at lower rpms would aid B2B or city slick drive, or the higher rpm peaks would suggest Highway friendly set of wheels,
ultimately, the curves would give a verdict of the ranges to be in! and so many other things..

And, Lastly

,
Lets have the Performance Curves to begin with, then we can check further!

@kpzen:

Thank you for the feed.
I think we can ask Pete and Autopsyche for their "real world" tested_on_dyno graphs, (if they would like to share).

Do tuners/tweakers/Dyno Owners here have stock curves for the Cars here in India?
If so, please contribute.

We can follow single post for a Car version
e.g.

Make/Car(year)/Variant: MS-Swift-K-series Petrol(2010)
Tested where/When: Dyno- (NFS UG2

)-13/03/2010
Other Details: The car is stock, Dyno (Odo reads 1000km), No problems, Normal fuel,
Snaps of Performance Curves: _snaps_
Conclusion:_Conclusion_

Guys i need Urgent help.

Need Dyno results for the Kseries Swift / Ritz 1.2

The test i did shows only 55bhp on the wheels.
Will post the graph tomorow.

Need to compare with another stock K series

Thanks in advance.
