Purpose: To move and shorten the air intake to the passenger side and install an electric supercharger.

Yep it's junk, im surprised people still fall for this.

"At full throttle, the e-RAM automatically activates to produce 1 psi additional air-pressure to the engine intake."

aside from it not working...

1) You shouldn't need to relocate the battery to install 1.

2) Nice install pics, but if you are going to post on here, you should have the common decency to show the install process w/ pics here & link to your site - instead of just linking to your site straight up.

3)

I'm sure that it's safe & working for you, but for me personally, that positive terminal is just a little too close to chassis metal for my comfort.

Good luck on your electric supercharger install. Feel free to post a review on it (and include dyno #'s sheet if you can) .

I have seen the errors in my judgment. No electric supercharger. I am going to continue with the relocation of my K&N filter to the passenger side. The next stage is to make an install a direct cool air feed pipe from the front fender into the engine compartment. It will start with a 3“ hole in fender into an electric rainy day gate into a four inch hole through the battery compartment, directly under the K&N filter. The filter will be connected to a short custom pipe leading to the throttle body.

1) Cooler shorter Air Intake:The air intake connected to the throttle body will be dramatically reduced in length and removed from running across the radiator. The K&N filter will be positioned pointing down in the battery location. Under the K&N will be a four inch round hole. I decided to run the shortest possible air supply from the bottom of the front bumper to under and through the battery box plate. The air passage way will be equipped with a remote controlled electric 3” shut off valve that can be closed in rainy conditions. I am thinking about enclosing the filter in a box. The box would have two one-way 3-Inch flaps that would open inward if the throttle body created an increased demand for air. I need more research to determine if a three-inch bumper hole can supply enough forced air to satisfy the throttle body.

2 Do you have any questions? I felt that the pictures did all the explaining.

3 Line is equiped with 80 AMP fuse.

I understand you want to run it passenger side, but supercharger/cold air/etc don't necessarily need to be done on that side (I didn't read that you want to move the intake to the passenger side, just that you wanted an electric supercharger - usually people lose a lot of credibility when they mention anything like that ).

I don't have any questions (I've done my own write up on battery relocation a while back), but typically, when posting diy's, people put the pics on here as courtesy (makes it so you don't have to visit another site just to see a write up). Also sort of helps build the repository the mods have been setting up (look @ tech articles).

Again, I'm sure you'll personally be fine w/ mounting the terminal there - even w/ your circuit breaker near the battery, just think about it: the short in front where terminal is gets to build up all the way (8-10 feet's worth) to the circuit breaker before it is stopped. It can get dangerous pretty fast - just pointing that out as a personal thing (and typically in battery relocation writeups, that's mentioned - people usually put a circuit breaker on both sides).

a steel drum taped to your hood wouldnt provide enough forced air for anything.

looks like fun on a sunday but i doubt there will be any gains.have fun tho, thats what its all about.
