Dyno Sheet Options

[parriehunter]

Hey had a dyno run and an interesting torque curve resulted.

there are a couple of points were the torque drops dramatically does anyone know why?


Here is the sheet, the drops are around 2000 to 3000 rpm and 5000 to 5500 rpm.


I was quite happy with the results considering it due for an oil change (only found out on wednesday we were able to do a cheap run and didnt have time to do an oil change)

let me hear your thoughts.

A 96 GT-T Caldina (turbo) only did 118kW at the wheels.
The top when we left was 150 kW at the wheels by a P10 turbo primera.

either a poorly calibrated dyno or you're getting knock and its retarding timing alot at those points. how are you tuned? what octane fuel are you using?

[parriehunter]

its not tuned, its just standard running 95.

i should of said its a st202 with a 3sge.

i compared my power curve with rustys and it was very similar shape.
The graph makes makes it look worse than i think it is because of the scale. going from 110 to 160Nm.

if it was knock wouldn't i get a warning light?
maybe it is poorly calibrated, but thats these guys do all day every day.
Cheers tho.

yea power looks the same between ours (mines higher by 4kw )

but I would have though torque to be smoothier?
I have........finallly 20 minutes later
a dyno run from KoreanJoey from CelicaTech which has a torque reading (I think this ones it)

[parriehunter]

Yea. its hard to compare, those little dips are 5 foot pounds, ~7 Nm. It does drop in places. doesnt look as sudden but has it been smoothed??looking at the top right I reckon it has.
Our power curves look pretty similar.

I dont know what to make of it.

Also 4kW is bugger all really, could be that it needs an oil change or that its done 150kms.
