No need to defend the e-ram (archive)

It's a good think to know, that even if the guy that designed the product is a clueless putz that produces inferior products, we shouldn't instantly disqualify it. (Slander Schmander)
Your arguement and math is good, you're just missing one thing, this product does none of that. It's a fan blowing air into an airbox at low speed, you could get more out of a peice of laundry tubing.
Even Kibort's math, when he was actually pressed, told the truth. With the fan on, the pressure inside the airbox (in this case, an e30 325i) went up by a quarter of a psi. 1/4 psi in the plastic airbox, ie: no gain in actual HP.
This product is aimed at the riceboy crowd, and serves more as engine bay dressing

: Nicholas, I have read all the responses that have followed this subject. One is from a list member who seems quite angry at at the inventor/vendor, so his opinion should be excluded. The other responses are from people who show moderation, but only see half the picture.
: This device is used with a relay that closes the contact in the 50 amp circiut when the end of throttle travel is reached. This very same relay likely comes with a n/c contact and a n/o contact. The n/c contact is a normally closed and the n/o is a normally open contact. When power from the micro switch/throttle switch is applied to the relay, the n/o goes closed allowing the fan device to start up. If you use the n/c contact and run the alternator current through it, when the relay picks up, it will open and stop current flow from the alternator allowing it to freewheel. All cars use a charging system which has a "storage Battery" This battery stores energy to be used at a later time. If the device is used infrequently, no harm will be done to the battery or charging system. As a Canadian, I have run my batteries completely dead just trying to start the car on -40 f winter mornings. (Starter current upwards of 100amps) I would not for a minute be concerend about draining the battery with a 50 amp current flow for several seconds at a time.
: Air flow
: What is important is how much air flow it will deliver. The super/turbo chager compres air/fuel mixtures, this fan does the same thing. If you push more air/fuel into the combustion area using any method, the engine will respond with a more violent explosion. Turbo engines generally use a compression ratio of about 6.6/1 to 7.5/1. This is usefull when there is a powerfull fan blowing stuff into the engine and raising the compression ratio to 12/1 thru 15/1. With higher compression engines say 8.5/1 thru 11/1 compression ratios the air/fuel loading from a large fan would infact destroy the engine, a smaller fan would just deliver an added little punch, raising the compresion ratio from say 8.5/1 to maybe 9/1 or 10/1 for a short time, thereby improving performance.
: Corolary
: This device if set up properly may in fact be a very inexpensive performance device. Do however research it further as I intend to.
