After talking to AJ (owner of ESS) in person two weeks ago, i got excited on the news about their V10 project E60 M5 that they have been testing and developing for the past few months…ESS’s goal is reliability and long term use and form this preliminary testing their really slowly introducing power to the motor and making sure this kit will perform well like their other kits out there such as the E39 M5, E9x M3 and etc…rest assured we’ll get more info soon but for now check out the dyno results/ testing at 6.5 psi and the flat torque which imho the V10 needs:) discussion here
