quattro diagonal test.
This shows how the EDS diffbrake system makes the car move out of this
diagonal wheel spin. with only open differentials, one front and one rear
wheel would spin, and even if the spinning front wheel got contact with the
ground, so that both front wheels had traction, the car would NOT move
without EDS, because the torsen center diff cannot transfer any torque if
one of the axles loses traction completly, as if one rear wheel is off the
ground like in this video, then that would be the only wheel that would
spin, all others would stand still. So the EDS uses the brake to brake the
spinning rear wheel so the other side that has all the weight also gets
some torque and add a overall load to the rear axle, making the torsen
transfer equal torque divided by the built-in Torque Bias Ratio (TBR) witch
i guess is 1:3 on this car, so the front wheels gets the rear wheel torque
divided by 3, witch makes the car move.
Audi S4 20v Turbo acceleration test
Audi S4 with Garrett GT 37 turbo, 465cc
injectors 3.5 "Downpipe. Drove 70-220 in 13.6 sec, however, missed second
gear. Tested the car on the highway with snow tires. It is good if you
consider that the car weighs 1800kg and with two 100kg guys.
Audi 200 Quattro launching with launch control/anti-lag
Quick clip I threw together of my 1991 Audi 200 testing the launch
control/anti-lag feature and some other footage for fun.
Stock block/head with 300k+ miles
VEMS EMS from EFI Express . com
Siemens Deka 870cc injectors @ 3bar base pressure
ClutchNet red pressure plate with 6 puck disk
Tune to 23psi on E85 fuel.
3" turbo back Exhaust
034 engine and transmission mounts
BBS RK 17X8 ET35 wheels
General Exclaim UHP 225-45-17
Suspension IS NOT STOCK OR WORN! Custom coil-over suspension was assembled
by me for this car and I am testing and tuning. The setup for this video
Eibach 550LB rear 2.5" X 6" springs
Eibach 450LB front 2.5" X 6" springs
Hyperco take up springs front and rear
Sitting on stock valved Bilstein sport struts front and rear
All new bushing and control arms
The struts need to be valved a bit stiffer to help with the squattro action
however weight transfer isn't a bad thing.
