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.Regards

: Needs input from ya... I had contacted the source, sounds reasonable and guarantee will works. Any comments is valuable.
