A lot more has gone into the Jade that you might be apparent at first. It's a lot of subtle work, but the new floor is going to be amazing. I think it debuts next month at Silverstone. I saw some of the CFD work
Last session I saw they were doing 54.0s at Silverstone National. lap record is 53.2. Hard to compare due of course. Harpham looked good as well in his MS/VM.
For those who aren't aware, there's no homologation for chassis or aero. So it's all out war. Engines do require homologation. Either pre-2001 GP engines, or FIA homologaiton for superkarts. Also twin-KZs are permitted. KZ is the 125cc shifter class. So with the Jade above it's literally two separate engines (and gearboxes)., most run inline VMs. The reason Jade run twin KZs as it's more cost effective. The ones above are slightly diff to standard KZ as they run digital ignitions.
Suspect one of these is far and away more mental.
