The kd4crs/Power Hungry/Gotts Mod (revisited - and with pictures)

Jack,

Thanks, you confirmed what I thought I was reading.

Granted I understand fluid dynamics are tricky, tricky. So take my musings below with a grain of salt. But, I live next to a PERFECT example of fluid dynamics gone wrong. Plus being a firefighter and having a master plumber for a father I understand the "common sense" wet side pretty well.

The author of the article was referring to a single cylinder engine and, at first, I thought well that's totally wrong for our 8 cyl application. But then I thought I remembered that with a V8 only 2 cylinders are opening at once correct? So it's not really that much different? Except for a convoluted intake path, a filter media and unexplained holes in both the resonators and intake tube.

If I'm remembering correctly I believe you posited somewhere here that the holes might actually be to remove some of the "springyness."


I rounded the edges of my PVC with the Dremel and a file because it just seemed to make sense. Probably didn't make a difference but...

Here's some ?'s for you guys also to ponder.

Do you ever think of where our filter is on a stock location compared to a cai?

Do you ever think of how much more volume a vacuum needs to displace when you have a cai?

Do you think the snorkle nozzle help to create vacuum and velocity at the same time?

Just some thoughts as I was doing a fire pump test today and had to use reducer nozzles to increase flow pressure at the hose monster pitot gauge.

I just got around to purchasing the alternate rigid 3 inch tubing that fordmt08 on f150onloine.com used for his intake modification and it looks like it will work well installed a couple of different ways. The tubing required is made by Spectre Peformance. It is part number 8741 for the black color (8742 is Red, 8746 is Blue, 8748 is Silver) and it is called: 3" Flexible Air Duct. It is priced ~$20 and should be available at O'Reilly Auto Parts and Autozone stores. I installed it completely collapsed using one of the two connectors that come with the kit to go into the fender inlet and using the downspout connector to connect to the stock flexible section. It fits perfectly and does not require any hose clamps. I will be testing it out with my Gryphon Custom 87 performance and Custom 87 towing tunes this week. This variation completely eliminates any possibility of the downspout connector collapsing or getting sucked inside out.
