Dyno Dynamics graph printout

what does all the data down the bottom of the sheet refer to?

Mate, I don't think your link to the sheet worked.

But from mine at a guess.........

BP = Barometric Pressure
RH = Relative Humidity
AT = Ambient Tamperature
IT = Inlet Temperature
RR = ?
TN = ?
CK = ?

Here's the Dyno Dynamics website link to dyno specs. Click on the "Specifications" link and then select one of their dynos. They have data sheets that explain some of the info/inputs/measurements.....not sure on the others.

Is dyno dynamics suposed to be the most accurate one. Coz there are few out there on the market.

brenx

They all claim to be the most accurate. Thats the way they sell their products

Sorry, but it wasn't a link, just a heading.
Where can I find the tractive effort figure on a dyno printout?
Can I please have some T/E figures for testing my calculator.

Thanks guys

I dont know if this will work(i am at work )

The dyno graph printouts can display what ever reading you chose (as long as it was measured).

Most will have POWER (hp or kW) on the left axis and the other (right) is up to you. Some are AFR (mixture), VACUUM, TORQUE or TRACTIVE EFFORT, which will be a line just like power or torque as speed/rpm increases. You know its just TE because the units on the side scale are just N or lbs (ie, no length units eg ft/lbs or Nm).

I got 1280 lbs of tractive effort (4.11's and 265/50x15's)

Brenx got 6600 N and 7950 N after the latest upgrades (4.11's and I think about a 25'ish inch tyre diam)

So both an imperial and metric example for your first crunching.

Yeah, the tractive lbs figures can be a bit up and down on these sheets. I looked at the other sheets i have with testing fron that same day, and one has 1791 lbs when doing 180rwhp??

Calculates to 330 ft/lbs
.
.
Using 25.0 inch diametre tyres . . .
.
6600N = 510 nm or 376 ft/lbs
7950N = 614 nm or 453 ft/lbs
