Assetto Corsa - Alessi -Monaco 1990 - Tyrell 019
Here, I try to get Alessi's time of 1:21.801.
Modded Tyrell 20 from ASR
-640HP at 13000RPM
-570KG
-New Aero and Tyres
-Using 1.05CL on rear wing 1.8 / 1 Ratio and 0.80CL on front wing 5.7 / 1 Ratio
-About 0.56CD of body Drag
-1.74CL on the floor diffuser. ( 0.17CL, 0.37CL, 1.20CL )
-Using CG of 0.400
-Changed Wheel base to about 2.89 meters
-1.83DX, DY tyres.
Every time I look at CFD of Aero Data on Internet, it seems to me they used about .20 CL less front wing then the rear wing. This also push's people to use more of 40% frontal weight balance, also diffuser seems like it was designed for this balance. Yet with my testing, it seems like it's better to have equal front lift and rear, and design the floor diffuser to keep this balance. It works in the simulator, not sure in real life. Also you can use 0.37 frontal balance with equal lift for rear and front wing. 0.37frontal balance doesn't work well, with the front wing with less lift then the rear.
Would be interesting to see how McLaren, Williams did it. Their front nose's seemed to have generated 6.5/1 Lift to Drag Ratio. Maybe even more for the Williams as the outer parts were lower.
