This long overdue Forum Build Thread update covers work completed on this wild 686 whp LS7 swapped E46 M3 from early 2018 through June 2019.
In that period we completed a lot of custom fabrication, including the elaborate radiator ducting and hood exhaust, twin filter box hood ducts, massive splitter and rear diffuser construction.
Many construction techniques and design aspects of these aero devices are covered, with over 100 pictures in this update alone.
Dozens of sub-tasks were tackled and completed in this update. A tune was loaded for the HPR built 468″ LS7, then engine was started, and lots of “first fire” testing was completed at the shop. Then it was off to the race track for the first track test.
We learned an awful lot at that test and brought the car back to the shop to fine tune many aspects and finish some of the incomplete bodywork. You can get caught up with that large chunk of work starting here. Thanks for reading!
