Note: This procedure involves editing a game file;
create a backup copy of the file before proceeding. Use a text
editor to edit the "enginerestricted.cfg" file in the
"gamedatavehicles" folder. You will see a list of
numbers similar to:
RPMTorque= (500, -30, 35)
RPMTorque= (550, -36, 42)
These numbers define how powerful the engines are. For example,
at 500 RPM, the engine will generate 35 units of torque. The middle
numbers (with the negative sign) control the level of torque when
the throttle is off (hence a negative number). If those last numbers
are made larger throughout the list, then the engine will be able
to accelerate through much higher gear ratios. This means at Talladega,
where top speeds are usually at 190 mph, your car can now travel
over 250 mph. The AI's engines will be also improved too, but
they will always use the old gear ratios, making their top speeds
only slightly better. They will make about 220 mph at Talladega
with full difficulty on. You should try to mimic the normal patterns
for these numbers (i.e., do not go straight from 50 to 1500 units
of torque in only three lines. Warning: These cars do have limits.
Their brakes are not any better, so you should not try going any
faster at the slower tracks. Increasing the engine power will
require trial and error to get the correct balance of speed and
realism. If the torque settings exceed 1800, the tires will lose
grip and spin (with traction control enabled). The gear ratios
can also be changed by simply making the numbers smaller. Finally,
for simplicity's sake, you can also simply rename the two *.cfg
files to trick the game into allowing a normal, unrestricted engine
at a Superspeedway.
