Custom headers and cam timing are next, if that doesn’t break the 6K barrier then intake revisions (plenum and throttle bodies) are probably next. For now I’m just going to drive it and enjoy the ride. Just had a great time at Japfest Goodwood followed by a track day there yesterday. Black Sunshine got a lot of attention and held its own on the track, what a great car to drive!
