I have a Model 3 that is about to return to service after a VERY slow engine swap, all that’s for another discussion. I have searched the threads and read everything relating to VGs here but didn’t find a good answer. So, I will be mounting VGs in the near future and I am trying to find a location that works well. I have the STOLspeed kits and have gone to their website that suggests 7% but then references a video which uses 3%. I have seen the 3% (1.25”) used a few times, have found reference to 8-10%, 3.75”, 5”, 8”. Most of the reports here that have solid performance numbers posted don’t go into detail about location, and those that mention specific placement don’t seem to give solid numbers. I may have missed it if it’s there, but can anyone provide a little info with both location and results?
