@@mrjarjar1018 hi. It's probably more car than kart as it has full suspension etc. however it is as small as I can make it. Check out the Palatov d4 for ideas, including four wheel drive. Cheers Stu
Are you gonna have aero vents that blast the ground right in front of the tires to keep water out from under them like Porsche first did on the 996? Also, I feel like that wing needs to be higher, up above the roll bar, and that the top of the body should roll over and off a little bit toward the back so that it isn't quite a perfect wedge but gets much less drag (if you can possibly do this without completely redoing the chassis design).
Hi. I agree the wing needs to be higher. However motor sport class rules limit it to 840mm above the ground so I'm kinda stuck there. Moving it back slightly is a good idea. I can go back to 400mm behind the body work. There is a very useful wing diffuser interaction that I'll try to optimise. Cheers Stu
Also good idea on smoothing the top rear of the wedge . I have modelled that in a scenario called parcel shelf. The interactions at the rear of the car between the wing, diffuser and rear vents are so complex that it is difficult to read the CFD. However i tend to your view, moving the wing back and smoothing the top rear of the car is intuitively the right approach.
you're making a racing kart with a RF900RR engine? because, that's what I'm looking into!

cool
Thanks. Spreadsheets can be fun!
@@damionrichter thanks... I must do an update video as there has been a lot of progress recently. Cheers Stu
@@Stu718 thank you cheers
