Priorities! You have them the wrong way round

Had a spare few hours yesterday so put the car on the dyno. I haven't had any time to play with ignition yet so this is running on my quickly bodged basemap. All i did was dial in fuel for .5, .7, .9 and 1.1 bar, also on a quickly set up open loop boost control just to get the values i wanted.

It was nearly 30* in the dyno room so a pretty big correction made, however on a turbo car i don't think the difference would be that massive so let's say it's 340bhp atm, not bad i'd say

 

[andybond]

Decent power that. Is it reacting as you would have hoped ?

 

[tutuur]

Well, tbh i expected the boost threshold to be sooner seeing all the reports on them. However i haven't properly tuned it yet either so hoping to have atleast 300lb/ft at 4000rpm

 

[andybond]

See what you mean , looks quite peaky. More dyno time ftw.

 

[tutuur]

Was bloody hot yesterday, spent nearly 7 hours flatout in the dyno room, had an DSC e92 m3 with 335i engine in before. So was pretty wasted at the end of the day....

an DSC e92 m3 with 335i engine in.....

Isn't that a backstep?

 

[tutuur]

With hybrid turbo's etc, deffo not!

 

[tutuur]

Got boost threshold a bit better in the meantime, still plenty of work to do though. Spent most of the time perfecting fuelling and finding out i maxxed the fuel pump/injector combo. With a few more degrees of ignition it could probably make some more power but nothing shocking probably.

Next up is 875cc injectors and DW200 fuel pump. After perfecting ignition on .6 and 1 bar i can then proceed upping the boost

Next up is 875cc injectors and DW200 fuel pump.

I am guessing you are using the 630cc now ?

 

[Ricardo]

Is it down on power from the first graph?

Std Megane 250 injectors with meg 250 fuel setup

Is it down on power from the first graph?

Yes it is, first graph was with the dyno not properly setup. We weren't sure on the calibration so had it re-calibrated

 

[Ricardo]

Figures don't matter its the smooth lines and how it drives. So it's the optimum now for the setup as it is then, next step like you say injectors and pump..... Spot on.

 

[tutuur]

Maxxed out the 225 fuel pump so fitted the DW200 pump, no more fuel pressure dropping from 6000rpm on so i could finetune fuelling and ignition.

Next result is on 0,55bar (actuator pressure):



And on 1,1bar peak, 1 bar constant:



Still on open loop boost control so boost curve leaves a bit on the table to improve!

Next step is fitting 875cc injectors and trying out the max of the BW medium actuator!

 

[Turbjj]

Numbers are looking good

What is a vermogensmeting afgesloten ?

 

[tutuur]

Google translate it

Basically it says 'end of run'

Google translate is a funny thing ! I know a little dutch and it doesnt always work correctly !
