Since we've all been talking about RamAIR, Cool Air Systems, etc...here's
something interesting for you all....
Just let them know of the basic formula for ram air. It is little known and
generally misunderstood.
Max ram at 80 mph is .08psi. max ram at 180 mph is .4psi (thats point 4
psi !!) This is with a 75% efficient inlet like on a dragster, that you
would never have with your daily truck/car. (Try 25 to 50% , best
case!!)
You can't get around physics, everyone tries. Anyway, this is right out of
Carroll Smith's "Tune to Win" racing book, as well as a basic known fact in
aerodynamics. (kind of easy to calculate.)
No matter what the shape of the inlet , (funnel, scoop, horn, etc) it
doesn't matter, ram just does not exist for our cars.
This is where the eRAM comes into play. It just takes unused electrical energy
in the battery, and creates a 200 mph ram air system (at WOT).
Ps . here is the formula for ram potential:
Air Density in lbs per cubic foot
X Velocity in feet per sec squared divided by 288X32.2 (all times the
efficiency factor)
Group buy anyone??? ;)
