I'm not sure I completely understand the terminology here. Are you saying your times were the same for 60 ft. or the full 1/4 mile, or both? I would not be surprised if it was both. People often underestimate the effect of reducing restriction on the inlet side. I'd suggest they try walking around breathing completely through a straw, then start to jog or even run. It usually doesn't take more than a few steps to get that point across. Generally though I would try to go as big as I could possibly fit in there (just to keep the flow velocity and turbulence down), necking up after the filter section then back down at the compressor inlet. Do some air flow volume calculations vs. RPM (or measure them) and then calculate the flow velocity. It was kind of a surprise to me. Remember there is no pressure on the inlet side, so it does not have the benefit of the compression as you do after the compressor.

The vbox is kind of cool. Never had seen one of those before. I'll bet that comes in pretty handy.

As for intake temps they would drop 4-5 degrees per pull where the factory would go up 5-6 degrees and eventually heat soak. Also when running the intake if intake temps rose for pushing through its paces it would immediately go back to original intake temps as soon as you let off while cruising a bit. The factory intake would go up more and more and would take for ever to go back to original intake temps.
It's not surprising he wanted one. A half a second in a 1/4 mile is pretty hard to find.

Did you do any temperature testing after compression - before or after the intercoolers or both?

As soon as I pulled out of the parking lot and started kicking it intake temps went all the way down to 115 and as soon as I let off went back to normal of 120 plus it was high 90's F that day. Everyone knows any intake sitting in a parking lot will heat soak as well as staying that way for quite sometime and no way for the car to run strong Immediately.
That's a big plus too. Have you done any testing on a stock intake setup to see how it behaves? I'd love to see the data, or even a synopsis like the one above.

The prefilter is mostly for those who have the concearn and to give them confidence when driving in the rain. As for sound you can't really hear it from with in the car you have to have your windows down and try to listen. If you have a full exhaust system and catless DP it's even harder to hear. But if you're walking down the road or in a car infront you can definitely hear it.
Do I understand you correctly that the filter media is a stainless mesh? Hmmm? How good is the filtration - smallest particles, etc.? Will the pre-filter change that in any way? I am also curious about the maintenance schedule and procedure on one.

If I am reading this correctly I assume all you have to do is wash the filter section then dry it, maybe even blow dry.

Now I am wondering what would cause the engine light to come on. Flow velocity out of range maybe? Excessive turbulence could probably do it too. I have only briefly glanced at the engine compartment but I did immediately notice an air flow sensor sitting right on top, just after what I assume is the right headlight filter box. Heck, I don't even know if it is a MAF or MAP based system - saw something recently about a Pitot tube/venturi sensor.

The intake took some time to get it right especially how anal I am in fit and finish as well as performance. I don't cut corners and take Pride in every detail.

All of that above really shows too. That and the really nice installation job Joe at Trinity did putting it on the car in the first post.

The 'back to stock' capability is a nice touch as well.

Joe - did you get to any of the dyno testing yet? I'm curious to see how your results and how they compare.

m6beast - Some of this is getting kind of technical, and maybe a bit off topic here too. Would you please PM me with some of this or shoot me an email please? I am sending you one now for the other info.

What do you all mean by 'fully adapted'? Is this the engine management system learning the characteristics of the new intake system - different air flow vs. RPM and manifold pressure, etc.?

My kudos to everyone involved - product, installation and the lucky owner.
