Electric RAM air

Has anyone seen this before? It looks like a load of crap BUT, if you upgrade the injectors and MAF, this should buy you SOMETHING, right? |

No
this is so full of fail :tongue: |

Re: Electric RAM air
Believable I guess. Any air you force into the motor( ram induction, shaker hood,etc. ) worked. Eliminating the air cleaner alone would increase power but ruin the motor with the grit it inhaled. The fan requires voltage and that requires the alternator to be loaded so the statement is incorrect that it does not add load. The "works under full power" statement sort of says you will never know if it is or is not working. Now if you could hook a switch so you could turn it on at say 2000 rpm and fell the car speed up then I would believe it. Snake Oil comes in a lot of different size and shape bottles <LOL>

Re: Electric RAM air
Haha... yeah, I've seen these things floating around for years. The classic "hairdryer supercharger". I remember ranting on these things on Usenet back in the day :)
Seriously... do you know how much air an engine actually swallows? If you do the math and figure out the volume of air you have to push into the engine to overcome the blockage you've just created by putting your "hairdryer" in there and then pump MORE air into the intake, you find that the power requirements for said motor must be ridiculous in order to provide any gains at anything above idle. Once you factor that power has to come from SOMEWHERE, you've then also got to install a much bigger (and draggier) alternator to provide the power, then up the boost in order to overcome the parasitic losses... and then you have to figure the volume of incoming air all over again. Ad nauseum. Etc. There's a reason that mechanical superchargers work well; they don't suffer from energy losses through heat to nearly the extent that electric motors do. As a result, their efficiency is FAR higher than any electric motor could hope for... plus it's pretty much directly attached to the engine for almost zero loss of torque from the turning engine. Turbos work because it's "free energy", i.e. energy that you're throwing out the back of the car already. I have never actually tried one, but every time I've seen these things advertised I just whip out my calculator and pocket protector then laugh :D |

Re: Electric RAM air
I switch to Mobil One and had to change the valve cover gaskets shortly after, my most expensive oil change! Once you have made the change stick with you oil of choice!!
Been there, done it!! Thanks to everyone making this web-site possible!! |
Re: Electric RAM air
Cool so somewhere between 5hp - 80hp,:lol: and, 900W at 12V is somewhere around 75A, and only works at WOT, which is (unless you are racing) rare, just what I want to spend my money on. :barf:

Re: Electric RAM air
gotta love the quick bolt on horsepower knock offs.
its like the guy with the civic who bought underglow cause he was told it added hp to his car. :P on a side note, last year at school a group did their capstone project on making an electric turbo. they rigged it on a lawnmower engine and they gained i think 15% efficiency i dont remember. Its feasible not practical :P |
