ive had 2 dynos done one when it was tuned and one just recently. that show a bit of a power difference. how come one flat lines at about 240kw then goes up again and the second one just gets stopped, could the second one possibly have gone up still. what causes the end of the 4th gear pull, user or car?

any help would be great.

first one



recent one

 

They look the same to me. Both hit 200kw around 110km/hr ~ 4400rpm

RTR revs it out to ~7200rpm/ 170km/hr so you get a better picture of whats going on and see where your setup/tune peaks out

Dynolink looks like they only rev it out to 145km/hr / 6100rpm for whatever reason. That'd be the operators call.
I'd bet if they rev'd it out further you'd see the same flat lining of power around 7k

Nice numbers btw.

 

thanks glenn !!

so do you think if dynolink had of revved out more, i would of got a higher end result like the first one after the flatline part?

 

I think youd get the same peak #'s maybe +- sparechange from weather etc etc

So ya dont think your cars making less power than when rtr did their thing.
You'd have to ask the dynolink peeps why they stopped the run, maybe they're used to cars that redline around 6500?

I just got my EF2 on so always keen to see how similar sized turbos like yours are running! Especially mainline dyno #'s which seem to be the standard here in Aus.

 

yeh i was more just curious i guess, its probably on average 15-20degress hotter where i live than melbourne where it was tuned, i didnt get it re-tuned at dynolink just put it for a run, id say there havent been too many evo x's on the dynolink dyno probably just the one or two tops. so they may not know the limiter. but its our only awd dyno in this town so im pretty **** out of luck. its booked in tomorrow at dynolink to see if they can nut out the cause of the dead rear o2, and slow response front o2 and rough idle. which ive had since the tune. doesnt really bother me but if its fixable would be nice to sort it out.
