Hi Ruud, I have a question about the pulling trucks, such as the MVJ2 above. At the start of the run, I've noticed many of the pulling trucks seem to pop and stumble, a bit like a 2 step. Same for the drag trucks that run at Onaway. The drivers will go through it and then give the start line a signal once they are good to go. What causes this? Is it a strategy in the ECU to light the turbo(s), or is it just a side effect of bigger injectors? Is it over fuelling enough to drown the combustion event? Is it intentional or something that just needs to be dealt with? Thanks for all your contributions here. Huge amount of high quality information you share openly.
Cheers.
