I did a calculation the floor diffuser is doing about 1.7CL in Assetto Corsa..at 209KG at 161KM.......1.7CL + 1.05 front wing + 1.05 rear = 3.8CL total in AC.... It seems like balance of car, front and rear lift were made to be the same, the diffuser was balanced to make sure it balanced. Having too much frontal diffuser would of meant less front wing, less frontal grip. If you look at simscale 1990s F1 High and Low Noses on internet article, it gives insightful information about frontal wings and how much diffuser they gain. This cars front wing seemed to gain the most in diffuser. I suspect McLarens were maybe pulling 1.4CL to 1.6CL, Benetton maybe 1.65 on the floor diffuser.
yeah thats about right. i guess for the game that an equal fw and rw sp;it makes the physics easier... The centre of pressure for the body from my sim is about 0.5m in front of the rear axle. I haven't calculated what that means yet....
@@nelsonphillips or it's 1CL front and 1.10CL rear, I set my balance at 37% front, Car drops down to about 34% at full down-force. It seems like 37% frontal is faster then 40%. But there's understeer, but you can go early on the gas, compared to 40%, where it might oversteer if you go too early.
@@nelsonphillips I reworked the car again, I got one those 20/1 diagrams and measured the wheel base it seems like it's 2.89m, had look at car again, then balanced it again, but now it seems like front wing is like 1.5CL less then rear wing for it to maintain it's balance. It's gives a lot less frontal down-force, probably inspires more 40% frontal weight rather then 37%, but you get more rear down-force. It seems like I'm wrong, with these car's have equal amount of lift for the front and rear. It seems like it's 1.5 CL to 1.0 CL difference. This is probably F1 Regulation limitations. If they could build a bigger front wing and a diffuser to match the balance, it would be quicker.
You should consider modding Assetto Corsa putting this aero data, then drive it. Its interesting, how the nose on the front, creates downward lift, but just before the diffuser it creates equal upward lift. I've always wondered distribution for the floor for 1990s. 1/ 6 ratio on front wing, 1 / 3 wing rear, 1/10 Drag to Lift for the floor diffuser seems be about right.
rear wing should be about 4.2:1. I haven't tried to get a close rear wing result. I need to spend a little more time on it. Especially with the wing mounts, there is a reason you don't attach them to the lower profile...
@@testdrive7772 I mentioned in the video that there are separation problems with the rear wing, and front, that are caused by the mounts. I plan to resolve this and do a video specifically about that.. but also the design of a triple element wing because there is surprisingly a large amount of stuff going on there.

beautiful stuff
Nice very, Nice .Whats 340 Newtons at 45m/s converted to Coefficient Drag ? I suspect 1990s to 1994's, had about 0.55CD to 0.61CD body drag
Body Drag seems a little low would be up at like 650 newtons?
1990: CL = 2.58, L/D = 2.85, 1990: 2300lbs@150mph ...That's Tyrrell's data for this car, I amuse with highest down-force.
The rear wing from that data suggest 1400-1500N @45m/s. I can get about 1200N without the mounts.

@@nelsonphillips Isn't that 3.22/1? it looks like Monaco Rear Wing

great content love to see more complex car like 2007 to 2008 cars
When F1 cars sill looked good.
