So, today it was time for me to do it again. After I was on a performance test stand in March of this year in the series state, I went to the same test bench again today to determine the change Stock CTR vs. tuned CTR. The result was more than surprising … but see for myself … Here dynamometer measurement and dynamometer from March 2004 (outside temperature approx. 2-4 degrees above zero) dynamometer March 2004Dyno March 2004 Here dynamometer measurement and dynamometer from this morning at approx. 09.00 clock (outside temperature estimated 23 degrees) dynamometer July 2004Dyno July 2004 First of all, I didn’t change the curves and data, you all read correctly …. Therefore my measures “-” tuning would have been and I would have achieved a lower performance of -15 hp compared to my standard condition. Luckily, I also had CTR11510 with the performance test stand. He was the first, I was the second. CTR 11510 (series) had even less engine performance than I should have, difference to myself 16. But the same condition was probably.
