My lid flexes quite a bit when you tighten the nut, you might not even need the weatherstripping.

Would you mind taking a pick of your 14X3 in the hat so I can see where and how it fits? Might have to alter mine a bit.

A word of caution:

I was checking the inside for bits of debris and noticed my circular air hat gasket that sits between the TB and hat was off in the back. I don't know if it moved when I put the hat on, or blew out. Just a word of caution. That might happen if you use weatherstripping on the air filter, now that I think about it. Be careful.

 

I chose the hat where the circular gasket was basically fused to the base.

Also, I am not putting weatherstripping on the filter. I am putting it on the rim of the bottom assembly. The 14x3 will seal to the lid, so I am not worried about debris.

I will snap a pic this evening for ya.

Speaking of pictures, I have one of aim4squirrels.

 

Aim,

Here are the pics of the 14x3 fitment. I am not exactly sure that the mopar filter (for the cast open air hat) is a 14x4. I think it is more like 14x2.75. But i will find out. I am going to autozone later.

As you can see, it is only a liiiiiiitle bit. The bump on the inside of the air hat makes it come up a bit. That is really where the issues come into play.

But some weatherstripping should fill these voids.

The lid slopes down, and the actual filter element is preventing the seal around the lip. It looks "good 'nuff" but it is not completely air tight. So weatherstripping should do the job wonderfully.

My progress is better today. I riveted and put some lock-tite glue on everything. I will probably put another coat of glue on tomorrow morning. Then tomorrow, I will be getting some weatherstripping. you used 1/4 inch right? That should fit over the lips perfect.

Love me some John Cleese!

Got the rubber radiator shrouds cut and reattached today. Sometime soon I need to get rain shields fabbed and installed.

I plan on looking for some large flanges similar to the scoop mounts and bending them out at 45* to 60* in front of scoops to avoid head-on rain, puddles, and heavy tire/vehicle misting. I can probably attach them to the same mounting point as the scoop brackets and leave the open sides to the radiator, above and below the scoop. This is essentially the same design that was on the original Dakota model, and I've never heard a story of a factory vehicle hydrolocking.

I'm actually a bit more concerned about light rain than heavy, as you really can't drive all that fast in heavy rain. It's when the rain is light enough that you think you can still drive the speed limit that scares me a bit. A few guys have told me they've driven this type of setup with no rain covers and never had an issue, so that at least gave me the confidence to try this.

We shall see...

 

Yes, I used the 1/4" tubing.

I actually left enough material that I can grind out the entire hump and still be sealed, I hope. I may do that and go bigger on the filter. I'll have to tap the IAT sensor in a new location and plug that hole with a piece of plate from the old hat.

Can I ask, do you have a scanner or means of seeing your MAP sensor info while driving? I'm curious if I am really restricted with this filter or not.

I suppose I could also put the round air filter back on and see if my manifold vacuum is closer to zero with that, than 0.9 in/Hg on this system. If so, perhaps I need a bigger filter.

 

That's Michael Palin, you silly tit!

 

Are you sure?

Doesn't look like Sarah's dad to me...

 

Aim could you run a prefilter setup on the two intakes, there made to keep the water out and would you lose enough air to make it not worth it....just a suggestion

 

With the scoops where they are, adding any resistance would not be beneficial IMO. The whole point is to get as cool of air as I possibly can into the engine. Resistance by added prefilters will slow velocity, cause the air to linger, heat up, and negate gains.

As the engine is still using vacuum to pull air, the deflectors will stop head on rain from running up the tube, but still pull in air of the same Temperature.
