      @@RotheliRacing Why was the HJS + DTUK combination not measured?
      Phil, inspirational video, as always.
      In fact, this result is not very flattering for DTUK. The dynamic simulation, based on the published engine brake output, shows a significantly larger differences.
      For idea. The idealized power and torque graph declared by the factory gives a time of 6.33s.
      DTE measurement - stock car (281k, 354Nm) = 6.30s, + box (309k, 399Nm) = 5.66s.
      Measurement PG Performance (Poland DTE dealer) - stock (275k, 388Nm) = 6.10s, + box (299k, 422Nm) = 5.59s.
      The torque course in the entire speed range has great importance. Other measured graphs for stock cars show results between 6.35s and 6.55s.
      I'm also going to compare stock with DTUK. DTUK had a very positive effect on me from the beginning (although I don't like boxes). Reaction to the accelerator pedal, appetite for speed. If it's just a placebo effect, it works very well.
      I want measured times for 40-70, 70-100, 100-130 (3rd gear) - this highlights the differences in power curves. Josef CZ

      @@nicolascageczechia1342 because i can‘t drive the DTUK legal on the street and therefore did it only once to measure and never did it again.
      It’s a race track mod only for me.
      50-130km/h is perfect for the HJS, because the turbo spool up is much better so that‘s where it gains it‘s advantage over the box.
      I‘m pretty sure the picture will look totally different if you‘d measure 100-200km/h.

    1:20 no! You need certain gas velocity to make the Best use of gas inertia and you need certain length to the point(s) where pressure change will occur- this will generate a negative pressure wave- it's called wave effect.
