And thanks for all the compliments guys. I just finished the other side today. Here are the pics:

This duct will feed cold air to my header, which will have a small aluminum box built around it to keep its heat from radiating around inside the engine bay and heating up the intake manifolds. The duct will cross the fan shroud and swing downward beside the air pump, under the AFM intake tube.



All in the name of volumetric efficiency . . . anyone notice how your engine has more pep when cold? Once those intake parts absorb the engine heat, intake temperatures rise, allowing in less oxygen for a given atmospheric pressure and engine speed.

You have lots of time on your hands huh?

A victim of ambition! My crazy ideas start controlling my life until I end up making stuff like the bumper, or paint job, street port, battery box under the bin, etc. I can't let the one time in my life when I had a garage at my complete disposal slip away without my RX-7 being a beneficiary in every way possible. So what I am saying is, I am an opportunist. My FC is just a simulation for me . . practice for a future small business probably. You have to make the most of what you have and take a plunge to get anywhere in life. Here I am!

Great work.. you've inspired me to do something with my brake duct now. Also, I was thinking about getting thermo tec wrap for the header. Why the aluminum box idea vs. header wrap?

that was some ingenious speaking in which most was not understood because of the lact of english (LOL yes very inpiring words)

Actually, I will be using 2" header wrap under the box. I will probably have about three layers of the wrap on the header before I use up the whole roll, and I will probably spray the wrap with some kind of sealing coating (which is recommended by the instructions which came with the wrap).



This might seem a bit much, but so is everything I do. Cooler engine bay temps create cooler intake air temps. Cooler intake air temps make more power. This is why turbo guys pay $$ for front mount intercoolers.



I will probably spray my intake manifold with some kind of ceramic paint (maybe even on the inside, too). Mazdaspeed7 coats the insides of his ports with a ceramic coating which I am too cheap to buy ($200 from Aircraftspruce.com) and I think he has the same idea as me: to insulate the intake air from hot engine parts so it won't heat up on its way into the engine.



Making power with an NA engine is simple but sophisticated. There are many tricks. This is why the original 10A rotary made over 120ish hp before it was detuned for American consumption. The first 12a's were the same way . . . detuned in later years down to a dreary 100hp.



One reason the 13B from the Gsl-Se is 10hp shy of the FC version is the curved runners at the top of the S4 intake manifold, along with thinner apex seals and lighter rotors. Little details like that add up. As you can see, I love focusing on the details.



I hope my writing is understandable. I try to write to the best of my ability.

That's some great information, I'm going to have to start thinking about that kind of stuff.



Your writing is completely understandable to me.

im stuck inbetween the air duck and the whole headlight conversion. its hte non pop up lights. they look like the 2003 nsx with no pop up. ive never seen that on an fc.
