Build a lid for Roto-Fab intake?

I see the ADM and CAI intakes producing a bit more power than the non-boxed intakes. Do you think its strictly because they are inclosed? If so do you think it would be worth it to fabricate a sheet metal lid for non-enclosed CAI's such as rotofab? You could even get fancy and make a little window.

Id imagine it woudnt be too hard to make if you had a nice bandsaw and sheet metal brake. What'ca think?

Been there,Done that and made over 1000 hp

I am sure if someone approached Mike at ROTOFAB he could work this out for them.

Rotofab makes fantastic products.

Would certainly sell a hell of alot more units as well.

Keeps the filter nice and purty and could def help in my opinion.

I already sell a lot of Roto-Fab intakes because of their impeccable quality, fitment and performance results. There are few who use a TRUE injection process.

With that in mind, why does the Roto-Fab need a lid? It already is designed to seal off to the hood, which is an equivalent effect in my opinion.

I think the problem is more of a perception thing. It just seems that a lid should be in place even though that may not be the case.

I can see that...
Thos eiwth the Roto-Fab installed will tell you it does seal pretty well. You can even see the lines on the hood blanket from the seal. They make a tremendous intake.

Exactly my thoughts......

It separates it in an ohterwise "boring" group of intakes.

+1 I am also very happy with my RotoFab. I like being able to see the filter exposed when you open up the hood, it just looks better to me. Not to mention, the product is made very well and you can tell right when you take it out of the box.

You can see the marks where it seals to the hood on mine, and if I shine a light in back of the air box itself, you can't see any light shining through.

The roto-fab seals just fine, and we aren't talking about like a 20 HP difference, more like a 3-4 HP difference. That difference could be from something as simple as a slightly different angle on a bend.

And personally, I think it looks kinda cool when I pop the hood, but I am a bit biased

Rotofab seals to the hood, so it is the same as having a lid. As for dynoing intakes..I would not purchase an intake based on results..the gains are just too small to be conclusive.

Intakes are like shoes..they do all about the same thing. Pick the style and price you like the most.

I agree. The performance differences are pretty minimal, so go with what you like. I bought the ADM intake because it looks great and it won't need to be replaced when/if I get a supercharger.

We have done extensive testing with air box sizes and configurations. Here is one of the ways we tested:
On an engine dyno we started with an enclosed air box with an inlet of approximately 24 square inches. After a few baseline pulls, we increased the opening by appr. 50%. The result was a gain in HP. Next we cut a the opposite side of the box which basically gave us a box with most of two sides missing-another gain in HP. We continued by cutting a third side out of the box-again small gains. The more of the box we removed, the better our power gains. Keep in mind the filter was always pulling fresh air-this was simply testing the effects of a box and crowding the filter with a wall. We did a very similar test with a larger box. Even with the same inlet area, the larger box performed better than the smaller box. We've also tested extensively with various filter sizes as well as air box sizes to determine the best compromise between the two. Incidentally, a bigger filter isn't always better. This is especially true if a portion of the filter comes close to a wall. The filter itself can actually prohibit air from reaching other parts of the filter!
Our testing tells us to use the largest filter possible while maintaining adequate space around the filter so the entire filter pulls air with minimal restriction. Of course, it's still important to isolate from engine compartment/radiator air. The best way for us to do all of this is to make the "lid" of our air box as high as possible. As many have stated, we do effectively seal to the hood with our top seal. We can't get a higher "lid" than the hood itself! If we created a true lid for our air box, it would be a slightly less effective system. I hope this helps our customers understand our approach in designing our intake system. One other thing...aside from the performance advantages, I like to see a big filter sitting there when the hood is open.

Well I switched to a zl1 hood and now it does not seal off. In this case I think a lid would be beneficial. Can you help me out at all with this situation. I am actually considering a different closed lid intake now that I need it to hook up like an ss but need a box like a zl1 or a lid so it doesnt depend on the hood to seal it off. THanks!
