Okay guys we just started developing our TDi Polo and thought for the benefit of all the members we would post our results. For the moment it is completely stock besides removed the rear muffler. On 12/12/09 We took the car down to Willowbank Test n Tune for the first round of testing.
Current Status of the car = Stock standard minus rear muffler removed. We know a few people had pulled the trumpet out of the airbox so we thought we would test that and report back with some real world figures.
First three runs of the day and the next 2 were run in similar conditions being it was a fairly quiet day. The car was run in street trim with approximately 1/2 a tank of diesel and only spare wheel was removed as it had a slow leak in it anyway. Still had change floating around the car and service books etc in the glovebox.
Each test was also run with the ESP Off.
Without the air trumpet in the box we recorded runs of 17.44, 17.43 and 17.38.
We then put the air trumpet back in and recorded runs of 17.22, 17.1 and 17.02.
Each time we launched the car in a similar manner. I figured I was probably leaving on too many revs but for the sake of continuity I thought I would continue with it.
Anyway after we had a fairly satisfactory base to compare results I started messing around with launches. At the end of the day we ran a 16.86 @ 79mph.
Next jobs on the card will be a full exhaust system, followed by Air intake, We haven't decided whether to try the PD160 intake or design our own custom intake. We will also be fitting a custom code ECU Reflash.
End result of the car will hopefully be to comepete in the Australian Tarmac Challenge next year and as we go we will post results and what is happening with the car.
Edit: Forgot to mention will post Timeslips when I can, left them at the gf's place. (whoops).
But as a quick review without the trumpet in I noticed a distinct loss of power and as soon as we put it back in it revved noticeably smoother in the top end.
