Electric RAM air

http://www.superchargerswarehouse.co...Superchargers/

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?

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

But they Dynoed it!

Quote:
Dyno results put the skeptics to rest. Our Supercharger kits are one of the most cost effective upgrades anyone can make to their vehicle.

Our dyno sheet shows that from the time we moved the throttle off of idle to the time we reached the peak of the RPM range, the horsepower and torque gains were consistent throughout the entire power band. That translates into a substantial difference and noticeable power increase when you get behind the wheel. Our supercharger setups respond well to additional modifications and you can expect your horsepower numbers to climb even higher if you're pairing our supercharger kit with other bolt-on performance parts.

Re: Electric RAM air

From the install guide:

Quote:
For the intake assemble, you need to make sure the intake is inside the intake.
Wut?

Re: Electric RAM air

Uh what? Your sales page says +80HP...


Quote:
5.How much HP gain can I expect?
Answer: Gains on stock 4 cylinder to heavily modified 8 cylinder engines have yielded 4-6% increases. That's 5-15HP depending on your base flywheel HP. If you are removing a stock air-box, gains for cool air tubes and cone filters are up to 5HP by themselves. The RAM with its 5-15 HP adds to ALL OTHER MODIFICATIONS, so with an intake tube will give over 20 HP of total gain for the RAM + intake system.

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

Yeah, they don't tell you much in the way of technical details. Any blower would need to provide positive pressure at air flows above 300CFM to gain any HP for the SVX engine. That's a tall order for an electric motor. But people have done this in the past for Nitrous type boost, as I have discovered when looking up data on electric blowers. They used a bank of batteries to run the high HP electric motor for a short period of time like what is needed for a quarter mile run. Supposedly BMW has an electric blower but I couldn't find details on it. But these little fans definitely won't be able to deliver any appreciable air flow at any reasonable pressures.

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, 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.

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
