The foil is a great idea and will work with moving air also, as the air will still be warmed radiantly by anything it comes in contact with so the lower the temp of the wall surface the better. As far as the snorkel goes, is there a point where the snorkel will no longer be the bottleneck in the equation when enlarged, but cause the incoming charge to lose inertia and become more turbulent.

Trouble, I agree. And there will be more test data. The snorkel's benefits are largely derived from the fact that it brings colder air to the Air Box. The Thermal Protection then reduces heat transfer keeping the air cooler. And your second point is well taken, because the velocity of the incoming air does modestly effect the static air pressure in the Air Box. So reducing that velocity would reduce air pressure. Increasing the intake size, if properly designed; while leaving the rest of the snorkel the same size and shape, will increase the air's velocity. And you are correct that turbulence generally reduces the flow velocity. JP

Reynolds number!!! :haha::haha::haha:

Hold on, let me calculate a number...does that mean it's turbulent?...sure, why the hell not...

Cookie, I love the feedback. And I've seen systems that utilize the principles you described. The FRPP snorkel flows quite well, but the BT guys would likely benefit from a system like that.

My goal on this project was to deliver the benefits of the FRPP snorkel, but at a more reasonable cost. Down the road, it would be fun to just go all out, with cost being no object. Thanks for the ideas and all your support. It's more than appreciated. I need it. JP
Glad to be apart of this, even in a small way @RocketST! I totally forgot the fact that the primary reason this project even came about was to provide an already great product at a better cost. Its a stellar goal, and while my suggestion/idea/thought was warranted it makes total sense to go back to the start of the project..which was to get a snorkel out there that delivers like the FRPP as a good price. Maybe once its out we can start a "v2.0/Race version" idea thread.

Wis, I sometimes think about how I got myself into two of the most obscure branches of physics. Hell, all I need now is some quantum mechanics and a VooDoo doll.

Thanks again for the help yesterday. Evidently iOS8.1 "needs" the FoST app. Looks like you got the last laugh on the Android v. iOS debate. JP

@RocketST: Hey, where's them photos at? Thought this was figured out...................

This is why I hate it when people say "you should know this, you're an engineer." There are so many branches of science and industry and this is why we have "experts" in very specific fields. It's impossible to know it all... I can take apart the entire hydraulic system on an excavator/backhoe/loader/etc... and probably be able to put it back together without the drawings, but I usually have to look at DIY videos on the forum here because before my ST, I wasn't really a car person...

I'm in a trance over that "foil". So far liking the results you're getting, would like to see similar results while in motion though. Really appreciate this effort you're putting in to deliver quality products!

ST2, The Snorkel is in "growing" in the MakerBot as we speak. I wanted some photos of the 3-D printer in action, as a lot of members seem to be interested in that part of the process. I may still get those pics today. If I hadn't spent the entire evening yesterday trying to get iOS8 to work, I'd be a damn sight closer. Thanks for your help this morning. It's greatly appreciated.

After attending a WEC race this weekend and taking note of the thermal foil used on the intake systems, I was pondering this exact topic to myself. I'm will most likely be wrapping my cp-e intake tube, and cold side charge pipe.

Oh, you don't say...

I thought iOS just...works.

Four sessions this weekend at the track. Ambient temps went from the low to high nineties. I didn't hit this with the heat gun but the air box was barely above ambient. Other STs on the track had the air box to hot to hold your hand to for an extended period. Sorry for not getting actual temps but things busy checking brake and tire temps between 6 cars (4ST 1 GT4 1 cayman), Pipenuts blew a charge pipe x 2, I had a left rear brake issue, and DesertST, ThunderLope, and Pipenuts had ground school, not to mention all the other stuff that needs to happen at the track.

That's great news man, thanks for checking on that. I really like that track, and you were layin' down some sweet lines. I know how frenetic track days can be, and it's easy to say screw it and blow off the details. So I appreciate the input. Best, JP

is there any benefit if one was to do the inside of the airbox rather than the outside? Just surious from an asthetic perspective. If you did the inside to keep the looks of the engine bay less "shiny" would the result still be a cooler charge?
