Make sure you put a screen in the ram air too to prevent birds from entering your engine bay at high speeds

Drifter, you could probably go with a smaller diameter metal pipe so the stock "accordian" tubing could fit over it...but I'm not sure, I don't have it in front of me. :? That sucks that cops are so damn picky. Maybe if you found that the accordian tubing didn't fit over it, you could cut it and wrap it around the pipe and clamp it around it afterwards. But if you kept the stock box, and had a pipe run to the stock box, you think cops would care? Maybe paint the pipe black? Just throwing out ideas

Humm.. I don't know what diameter the smallest rib on the accordian tubing is.. but I don't reallly want to go too small and loose the whole affect of it.. mind you if I had an adapter in the front ( inside the airbox ) that converts it back to 3".. that might work since it forces the air into a smaller diameter this a higher velocity.. but would the air be sufficient and efficient to warrent a gain and work of it.. hummm.. good ideas still though Pete.. I thought of painting the tubin black too.. but black draws/absorbs/retain heat.. humm... :?:

Hey Drifter, I think the accordian tubing will fit over a three inch pipe. It might be a little tight but it will fit. I accually had to put one of the accordians over my intake. If you know what I am talking about mine had a larger rubber piece that went over the Intake where the MAF is, since I have been working on this I have my intake in and out alot and that rubber ring came off, so the only thing I could do is fit the tubing over the TB. If it won't you can always do like bonnie94sse suggested and cut it down one side and wrap it around the pipe and attach it on the under side.

As for water I am not to worried about it for now. There is going to be about 14" of PVC at 35 to 45 degree incline going up to the headlight and then a right angle then about 12" of PVC that mounts into the air box. I plan on mounting a screen over the end of the pipe and I am still thinking about if I want to run a pre-filter. I will figure it out once I get the ram air done and run it a while. If I start to have problems with it getting to dirty I will find something to run as a pre-filter and if I have problems with rain I will make something that will turn the end of the ram air up or down so it does have the rain forced into it. Does anybody know how the Grand Am'* Ram Air works. I have looked at one before but not very closely. I know it has the collector in the grill and the it goes in between the top of the radiator and the hood it is only about .5 to .75 inches think but goes all the way across the top of the radiator so it is probably 18" long, then it goes in a pipe the feeds the air box. I am not sure if it uses any thing other than a paper filter or not of course it has the grill to keep out the larger items.

My main concern it, I have heard about a few people with ricers that had some kind of ram air or cold air intake that was mounted really low on their cars and when they went through a big puddle of water the pressure of the intake sucked A LOT of water in to their engines and completely locked it up. Of corse everything I am doing is all experimental I have not seen or hear of anybody doing this kind of ram air on a bonneville so everything I do I will have to test and see what does best. Right know I just have the 3" PVC behind the headlight and I have been running 93 octane gas and am getting about 17 to 18 MPG of course I have been driving it really hard since I opened it up.

One last thing, I think I am going to put my MAF screen back in or cut it down and put a piece in front of the MAF sensor. With this kinda pressure coming before the intake I really want to get a good reading from the MAF esspecialy since I am leaving the stock box and tubing.

dont forget to read the link in the ram air article, its pretty interesting, and will probably help you out alot.
