    90mm, yes single rear silencer. If everything ok in the next weeks, the car receive a new settings for 1.4 bars, LC, ALS , a raised rev limiter to 8000 rpm, and a set of Hoosier drag radials. I was in the car most of time, so i did not catched on camera a full trothle third gear pull , the sound is amazing - it pulled around 0.5g at 160+ kmh (if my gtech worked right)

      New settings, 8000 rpm limit, from graph, the car still pulled strong around 8000rpm , 1.6 bar boost. I don have a lot of experince, but i think it is a very good result. No more races this year, so i dont think i will have were to try the new settings, maybe next year will be better, an hopefully get a 10 sec run.

                Some updates, my tuners modified the timing, to bring the powerband a little lower in revs. I did only one race, bad 60ft, no LC, and ALS, street tyre on VHT, result
                12.2@206 kmh (i changed to 5, even if it was not needed) , 2.24 60ft. I was lined with a 700+ TDI, dont know if it was at full potential, or not, but i was pulling a little on him, or at least so it seemed to me . Hope for better on the next runs.

                      11.3@211 - 1.99 ft , used als, but bad setting on LC - 4500rpm, or so , and bogged a little, a little wet surface, but I think that with good start 10s run can be made in this configuration.

                          New race, could not get under 11.05 .
                          I had some good 60ft - 1.68 - 1.7x on street tyre, and not so good road surface, but i did some 11.2, 11.1, and 11.05. I will make some changes on rear suspension / and maybe try the drag radials.

                            Update, just found the weight of the car - 1400kg with driver on board. Seems a little to much, i'll try to bring the weight down.

                              It's not that much...
                              S4 with climate control ripped out, all seats out except driver and 20L fuel was 1648kg with driver.

                              So you got 250kg less weight already...
