On sunday I finally got a chance to finish setting up the ED30 with some road datalogging and dyno testing we ended up with:
Boost:8
Timing:8
Fuel:5
Mods are:
Milltek full turboback 3" decat resonated system
Dbilas/pipercross DIY intake
Autotech fuel pump
DSG stage 2 REVO
Forge Twintercooler
REVO stage 2+ software

(photo missed the dyno calculations at the bottom which were: Intake temp: 37 ambient temp 23 Barometric pressure 1013 humidity 45)
The addition of the twintercooler allowed us to take timing from 5 to 8 which took the car from 357bhp to the figure you see above, however torque has dropped from 380 ft/lb as we had to lower boost from 9 to 8

Looking good mate :) :congrats:

Looking good Dave :happy2:
-
awesome figures for DD rollers. How come the curves are so condensed, is it possible to spread them over the complete width of the graph, its better to compare the curves with others then.
the new dyno graph thread here as well :happy2:

would look better if you could get the torque an power figures on each side of the graph the same
-
Timing 8 OMG, were you on normal 99 ron or race fuel?
Did you get any logs done?
Good result on the run :happy2:
-
I can adjust the scale of the graph but this is how we set up the screen for all dyno tests.
Hurdy, this was using 'normal' 99 octane fuel, the twintercooler really helps keep intake temps really low, we saw a timing pull figure of 4 degress after a few 4th gear pulls but intake temps were still at just 34 degrees. On the dyno this raised to 5 degrees of pull and an intake temp of 43 degrees after 3 dyno pulls at WOT.

throw it in the new dyno thread :happy2:
-
The rpm scale is not shown so could you state @what rpm do you see your max hp at.
-
Looking good! :happy2:
-
Interesting results dave. Looking forward to getting mine dyno'd now and seeing what results it gives!
-
Awesome results mate. Looking forward to seeing what mine will make on DD rollers on Sat (same mods, just without the the cooler and standard Dbilas). Although it aint going to be as high as that even though I have the same mods, just without the the cooler and standard Dbilas (not hybrid).
I will however be running early in the morning so that should help as the temps on sat according to the weather should only top 18oC. Just unsure what settings to run, as I don't have VAGCOM :sad1:
Any ideas?
-
Are you stage 2+ Ben? Go for b8t5f6 if you are as a baseline.
-
That's exactly what I am at the min mate and seems pretty good. Just don't boot it much when it gets silly hot outside (like 25+ on temp gauge).
-
I'm running that also B8 T5 F6, and have logged it and its all pretty good as shown by the results at the Halifax RR day :happy2:
-
gaz, post your graph up in that thread, and then if PDT can change the scales on his graph we could make a good comparison between the two. iirc yours was similar at the last RR day??

will do after dinner pal

dinner at this time of day. never, you must be about o have tea, because dinnertime is at midday :grin: :laugh:
ill just get my coat :sad1:
Sy :grin: :happy2:

As for the temps on the day, it wont really affect things as the Dyno (all dyno dynamics will have) has a weather station so it will forward/back calibrate the results so the weather on the day wont affect the final result.
i.e if its an extremely hot day the dyno will add to the compensation figure that determines the losses due to increased temps. On a cold day the dyno will do the opposite and take power off the actual figure. This way if you have a car that you get on the dyno quite often (we get customers that ask us to map their car at the beginning and the end of a season which is ofen a difference of temps of around 30 degrees ambient temps) it will still make the same power regardless of the weather conditions. this way it removes the variables and allows you to concentrate on facts as you are mapping / testing
-
it makes a different when runnin the std cooler though, mine suffers heatsoak on the dyno in this weather, but is ok if i do it when its cold

That's more where my problem may lie Sy. But very interesting about the DD rollers and the weather variences, clever stuff that. :wink:

That's a pretty nifty feature, not heard about that one before. So what temperature is it calibrated to where it doesn't compensate at all?
-
its not just temperature that you take into account, its also humidity, barometric pressure, intake air temperature etc..... so determining the absolute temperature that they zero calibrate at isnt as simple as it seems.
If your car starts to heatsoak on the dyno then the dyno needs better cooling, ideally a dyno run should match as closely as possible to a road run in both intake temps and pull time, but most dont. We spenat ages testing different fans and even though we now have an OK setup it still isnt ideal, so I have now invested in 2 more fans that are capable of this:
I predict a few number plates going on a journey :signLOL:
-
Haha that looks like a very powerful fan. Do they do fans that mimic airspeed as the speed of the wheels increases? Like the wheels doing 70mph the fan is blowing 70mph? Always thought that would the most accurate way of seeing what power the car is making as it is moving along.
