i work for a stainless steel manufacturing firm. some of the stuff we sell is designed for hvac systems. we've even sold parts to intel.... and your statement above is the strangest thing i have ever heard. also note that a rough surface leads to dirt/bacteria build-up as well as promoting a larger heat exchange due to turbulant air.

Ever wonder why a golf ball has dimples and isn't smooth?

I'm sure the 1\2 MD is great also, but they were out of stock at the time I was ready and I didn't want to wait... I am really happy with my SKUNK2 tho... I wouldn't do anything less than 1\2 in. unless you just cannot live without that plastic engine cover. IMHO

More air passes through your engine in 10 minutes than will flow over a hundred gulf ***** in a year of play. In auto machine shops all internal work done for high performance applications is well polished, always, no exceptions due to the need to alleviate build up of foreign material. Golf ***** have dimples for other reasons so this is really not a good comparison to offer.

Also; why do golf ***** have dimples;

Golf ***** actually used to have the dimples sticking outwards (outties, not innies)

Anyways, I love how the guy in the video is dragging the plenums around, smoking, etc. Makes you wonder how they were able to design and implement the product!

You can refer to my later link if you wish. But the point is, the golf ball's surface is not smooth.

Ford has also done extensive research into flow over smooth vs rough surfaces. Their research and development budget far exceeds any machine shop.

Also your link does more to support my theory than hurt it. Even though my golf ball link is much more accurate

Being a solid has nothing to do with it. The correct term is fluid when talking about these types of things/properties. However, air is a fluid, so it does make since....

So your trying to use FORD to back up your theory, LOL

Also, this is not just any machine shop, everything I've ever purchased that was professionally ported was POLISHED. I've been in and around cars all my life and have personally built more than 50 engines, my first was a small block chevy, I was 12... My friends at southland dodge have built & race cars since the 60s and I've been around it all my life; I know about this stuff man and your theory is wrong! They race Mopar Hemi powered cars, the same engines in all Chevy, Ford, Pontiac etc. dragsters etc. and all have very smooth polished internals.

Here's a few links to check on some cool fast racing and none of these cars have rough passages; I'm sure of that.

I don't have time to get into this to prove a point but the info is all out there, Google is a good place to start. I think you should go do some research!

All those links might show is that they all do it.(well they don't even do that really) Where is the research to prove it??

So Ford is bad but you include a Neon link. Okay

You do the research man, it's all over the internet and just cause there may be neons on some of the sites, these are NOT neon links, just something to backup my racing background with Mopars and I can tell already that you have not done anything but look at the pictures.

What are you trying to prove anyway, we all know Ford is bad and I'm driving an Infiniti now, not a Mopar of any kind and damn sure not a Ford ever again!

I have done research as the links illustrate. All you have done is provided links to performance shops and provided little technical reference.

I provided a link DIRECTLY to what I was refering to in my statements. I'm not going file though the whole site to get to what YOU are trying to prove.

I really like the general and sweeping conclusions regarding Ford. I doesn't help your case.


Not a Neon huh? This is on the opening page of the site YOU provided:

Guys take it easy . . .that was a impromptu explanation that I did 4 years ago when a customer from AK came up to get all our stuff on his 350Z. He begged me for an interview type explanation for the product.

If it makes much difference I have since quit smoking . . .what is beyond me is that I usually have a miller light too and I didn’t have one in that video.

Maybe we will put a more professional video explanation up soon. Oh yeah, I fixed Infiniti on the front page as well.
