With the car running consistent 9.9s 1/4 miles on pump fuel and stock turbo it's time to set our sights on the next target, 1000bhp!
To do this we're following in the footsteps of our hugely successful S63 Engine Build package in partnership with Mr VANOS. Together we've been building the fastest and most reliable F90 M5s for the last few years and we hope to continue that legacy with the S58 engine found in the G8x M3/M4.
In this video we join Steve as we take a look at the internals of the S58 engine, how it differs to the S55, and what we're upgrading and developing to make this engine in to a true powerhouse.
Plus who doesn't love a timelapse of an engine being built!
