The way you have it is really the right way (shortest path - straight line), and there are kits for mine like that, but they would not work with my hood. I originally made an air box from plastic panels and it worked but as I was told, the engine / MAF is very sensitive to any changes in the air path / air flow. It kept throwing codes. So I figured that if I could use the stock box, that should solve that issue, and it did.. As for performance, it makes no difference other than it is louder under the hood. The MAF is in the stock (rotated) location.
Everything I have read on cowl induction and ram air shows that you have to go well over 100mph to get any measurable benefit. So for NASCAR, yes - me, not so much. I measured inlet air temp (at the filter) before and after the new hood, and there was virtually no difference. In fact, since the air path is all convoluted through the hood channel and then down to the air box, the truth is that I may have actually hurt the performance a little! But to have functional ram air, it is the 'cool' factor more than anything.
I tried to make it look decent and not home-made (no duct tape). I could probably work on that foam seal and make it look better.
And now it is just no fun keeping up with all the horsepower bumps. In 2005, a 300hp V8 was respectable. Now a little V6 Hyundai has more than that, so I'll just drive mine and not worry that some little punk in a '92 Accord will smoke me with his juiced turbo 4. Stock Mustang GTs are north of 400hp now.
My Impala has headers, 3-chamer Flo masters, and rather lopey cam in it so it is just fun to sit at a stop light let the whole car shake and see the odd looks from the people sitting next to me.
Computer stuff is more my thing now. And even that is hard to keep up since what is hot now is outdated in 6 months. I have a Thermaktake X9 case on its way for a review soon, which I am looking forward to using as my personal case (switching from a Corsair Air 540). The X9 truly has room for multiple radiators.
