EVERYONE: Please take the time to note / look into what intake setup Bob Cosby is running. He runs 11.8's in a N/A'd 99 cobra with bolt-ons ONLY. He sure as heck isn't running the stock tubing and he isn't running MAC, BBK, or AFM power pipes.
Yes ladies and gents, he is running an almost identical setup to what is sold at www.densecharger.com
He runs the exact same power pipe as them and his CAI elbow before the MAF is similar and made by WMS Racing out of Canada. The WMS is made out of metal while the DC pipe is plastic.
No offense, but have you run before and after tests on the dyno, track or datalogging your intake temps? I have yet to see one "gain" in HP/TQ that has been substantiated by dyno, track or other meaningful comparison. Personally I would never use a metal inlet pipe. Especially between the TB and MAF, because that part is directly over a hot valve cover and exhaust manifold.
Also, not to flame, but just because a part is popular among a certain "group" does not always mean it is good for performance. I will admit that going with the "crowd" when coming to a performance decision usually means you are making the right choice, but not always.
Think of the ACT sensor(air charge temp) that will be in almost direct contact with either A) plastic tubing or B) metal tubing. Think about how much warmer the air will be due to the metal being hotter than plastic. That air will cause the ACT to say "I am getting hotter air now, so I need to retard timing" Well anyone who mods stangs knows that retarding the timing is not good for performance(unless blown and you are trying to fend off detonation).
People complain that their metal shift knobs get incredibly hot if they are in hot weather stop and go driving. This is because metal transfers heat much better than plastic. If you screw a metal shift knob onto a metal shift handle, that is attached to an all metal tranny, that gets extremely hot, you get the idea. But with a plastic shift knob, you will hardly ever feel it get warm. This is just an example that I thought of that would prove my point a little better.
However some people care more about what their intake pipe looks like as opposed to what it performs like. Personally I would rather have something perform as opposed to looking good. How many times a year are people going to say "Wow! Your car is fast! Is your inlet pipe chrome!?"
Unless you are big on chrome and enter your car in every car show you can, then you are wasting your time and money on the MAC or BBK setup. Ask any 12 sec cobra owner if they have the BBK or MAC inlet tube and they will say no. (At least every sig of every 12sec cobra owner that I have seen does NOT list a MAC or BBK "Cold Air"
kit) There may be one or two with the AFM, but that is quite a bit different power pipe and it puts the MAF in the fender. Plus I believe it requires using a Pro-M MAF specially calibrated for that setup.
