THE Ultimate Power Mod...
All this talk about heads and cams and superchargers ... all wimp stuff I tell you...
This is it. The electric hair-dryer supercharger....

Re: THE Ultimate Power Mod... (MMI)
There are other discussions about this on the forum, most don't think it will work. Besides it says it will work on engines only up to 5.0 liters.
good thought though

Re: THE Ultimate Power Mod... (SHOWTIME!)
Some of it makes a degree of sense, especially when you read some of the Ram/Cold/Larger airbox wars we so frequently have here. I quote:
7. Don't Most cars have ram air already?
Answer: No, most manufactures have done everything to make inlet ducts to get air into the engine. The problem is that because of the path the air has to take, by the time it gets to your throttle body, the air doesn't have enough pressure and speed to add any ram pressure to your intake system. Even at speeds of 80 mph, no ram effects can be measured with an almost perfect inlet system, (i.e. less than .08psi) At 160 mph , that pressure goes up to .36psi., that's it!! Horsepower robbing vacuum in most air boxes is present due all sorts of restrictions as we cant have dragster style hood scoops on street cars because we would not be able to see over them!
8. What causes most of the intake restriction, and how do you measure how much you have?
Answer: Filters, inlet turns, diameter reductions and obstructions of the intake system create pressure drops depending on the restriction, resulting in vacuum in the air box (less dense air). Using a sensitive pressure gauge, this vacuum can be measured under W.O.T. either statically on the dyno, or on the track as we did.
9. What is the difference in drawing engine heated air versus cool outside air.
Answer: Every 40 degrees makes a difference of 6% HP. The pressure would have to rise 1PSI for this gain in HP. Conversely, the air pressure could drop 1PSI at altitude and the losses would be similar.
10. If the eRAM produces a positive pressure in the air box, how does that relate to HP gains.
Answer: In the same way that you loose HP when you travel at altitude because the air is less dense, you gain it by increasing the pressure. For example, if you travel at 6500 feet, the air is 3PSI less dense than at sea level.(on average) This 3PSI doesn't seem like much, but can be responsible for up to a 20% HP loss. If you could produce a 3 PSI supercharger, your gains could be in this range too. (Ignoring the heating of air due to compression) At 1/2 PSI, gains are in the 3% percent range.
