So that whole Ram Air induction that Dodge toted back in the day was probably a load of crap too?

It works on a dyno because the car is sitting still. Redline in 4th gear = how much speed = how much air pressure at the front of the car?

We did something like this with a guys RX7.

Typical 2nd gen Turbo RX7's have a hood scoop for the top mount intercooler, when you go to a front mount its basically become a decoration. My mechanic / friend made a very trick air box to put on the hood scoop and feed the turbo outside air and when at speed under pressure.


We put the car on the dyno and did a pull with the hood down. I cannot remember the exact RWHP right now, then we did a second pull with a leaf blower blowing at the front of the car just in front of the hood scoop. The car picked up about 15 RWHP.

Why?

Because it was getting some clean cool air, much like it would on the street doing 60+ MPH.
