Water Injection Thread

[Gary Derian]

A couple thoughts:

Transmissions only see  torque.  Power ratings are not technically correct.
If someone is rating a trans for power, find out the rpm range and calculate
the torque they really mean.  The only effect power has is to heat up the
lube.  An oil cooler can fix that problem.  Usually its the output side that
breaks when in 1st gear due to the torque multiplication.

Intercoolers are great for cooling compressed intake air resulting in higher
mass flow.  Water injection is great for its anti-detonation qualities.  Use
both!

A heavy flywheel absorbs torque when the car is accelerating, especially in
the lower gears.  This reduces the stress in the transmission.  It also
smooths the torque which also helps.  But don't dump the clutch, here the
flywheel weight hurts the trans.  I think a soft clutch is a great way to
save transmissions.

180 degree headers on a V-6?  Wouldn't routing each bank into a turbo (3
into 1) result in 120 deg and every other pulse into each turbo?  Same for
intake.

AWD is really great for low traction conditions and year-round driving.
Rear wheel drive with a mid engine and sticky tires should be nearly as good
on dry pavement with way less complexity.  How and where do you drive?
