Dyno result success

[AzE_B]

You are of course quite correct, however if you look at the scales on either side of the page you will note that they are different. 0-220bhp against 0 - 180 lbft.
If they were scaled the same, the figures would have crossed at 5252 as they should.
From what I know about the Dastek it automatically scales the figures on the sides of the page to make the graph fill the page.

o yer i didnt see the torque scale on the other side my bad

Me neither, well spotted enginetuner!

Great result mate bet it shifts well on the road

nah its wrong mate, if you take the scale outa the equation and just read the graph, its wrong.

4 cyclinder engine, for whatever reason has equal torque/hp @5250? yes? yes.

at 5250 read both torque and hp figures? even without the scale differences they simply arent eh same figure. @5250 155lb/ft and 210hp. roughly

Phil,

It would probably work out.
It doesnt matter what the readings are at 5252rpm, it will cross if you scale the torque reading with the power scale.

[Phil]

if the torque scale was made the same as the power scale the torque curve wouldnt even cross the power curve at all!!

it cannot see how it would work out, if you rectified the strange graph/scales it would only make it more unusual looking/impossible?

Rory

geeheehe, im wrong your right

i thought the torque was the hp, my bad. its still out but not nearly as bad as i thought!

You have the graph lines mixed up Phil. The power curve is the lower line.

heh yup, sorry for spamming your thread mate! its not as far off as i thought the fly figure is still pie in the sky, but id trust that whp figure ok

I was just about to say....

Leave the graph size as is, and bring the torque scale to suit the power scale, ie make the 180lbft, and change it to 220hp, it would bring everything down in the graph.

I blame Dastek for the confusion.

 

[spuddy]

The readin I got on my car from a Dastek rr crossed in the safe place as urs does, I also think the fly power was a bit high, will know soon enuf takin the car to another rr so can compare the readings.

I'll be interested to find out what conversion factor is used at your other rr

 

[WillGT]

dont worry jezza my rr printout is like yours its scaled differently when i looked at it i was like wtf but after looking at yours and mine and everyone explaining i can work out how mine works! lol great result by the way!!

 

[WillGT]

one other thing how did you take such a clear photo of your result i take a pic of mine and it looks like blur on my cam and you cant read it!

Use your macro setting on the camera. The symbol looks like a flower. Best way to achieve focus close up.

 

[spuddy]

I'd be fairly confident the Wheel power on my graph was correct TD04@1.1bar made 212@wheels but flywheel was 248@fly

oh right haha thanks mate i'll use that, i can post my graph up then! cheers mate

Crackin result Jezza, could i use this dyno graph to add to the others?
