Default A2A Supercharged Intake Options

So awhile ago, I wanted to break the A2A discussions in to separate threads due to the massiveness and great usefulness of the current two threads.

Here I would like to discuss some ways to increase the efficiency of the kit from the supercharger suction side.

Bewhitey came up with a 3D printable induction tube that requires extensive radiator support modification.

I recently ordered some components to try and make something similar that will require less support modification. Essentially, it would be some 3.5" silicone tubing with some aluminum support bits. The route would be (it sounds complicated right now, I know):
Supercharge intake,
to 3.5" silicone coupling,
to 3.5" x ~4" long aluminum tube,
to another section of 3.5" silicone tubing that would pass through the hole on the driver's side similar to the intake Y pipe on the passenger side,
to an aluminum 90 degree bend,
to a much larger intake filter, similar to what Bewhitey used, but skinnier, I think

I get the parts on Saturday while I'm out of town, so Sunday after church I plan to try to get everything cut and assembled, as well as get some data logs to compare.

What I've ordered:
HPS (HTST-3F-350-BLK) Black 3.5" x 3' Long Straight Silicone Hose Coupler Tube
1 x Vibrant 12055 3.5" O.D. Aluminum Joiner Coupling
1 x Spectre Performance 9732 Universal Clamp-On Air Filter: Round Tapered; 3 in/3.5 in/4 in Flange ID; 8.75 in Height; 6 in Base
1 x Ispeedytech 3.5" Performance 90 Degree Tight Radius hose Cast Aluminum Turbo Elbow pipe 89 mm

The reason for the coupler in the middle is to reduce the length of unsupported silicone tubing and prevent collapse under vacuum. This may or may not be an issue, as I'm looking for about 12psi, but I figure better safe than sorry.

Any input or discussion would be fantastic!

just bought my kit so I'm excited to see if someone comes up with modifications on it.

Here's what my shop designed and made. Not cheap but the best I've seen for replacing the current filter that comes with the A to A kit.

This has been on my radar for awhile, just haven’t had my car to start on it. My ideas involve 3D printing. How do you plan to transition from the supercharger to the “hole”? It’s not a straight shot. And 3.5” tube? I think even the admin tuning 3” intake resulted in having to squeeze the tube to make it fit.

Iím making 12.76 with the stock filter. What are your thoughts on that? Not convinced itís a good thing... supposedly from tuners cam timing. No idea what power itís making.

Yep!

So the parts came in early. Some cutting is required, but it doesn't seem like it will be a crazy amount. Modifications will be similar to (but more than) how the charge Y pipe came through the passenger side. I've had a lot of distractions yesterday and today, but tomorrow I should be able to get it all done.

There's no way to get any kind of aluminum coupler in there, so I'm toying with cutting it to about 1.5-2" wide and using it that way to still provide some support. We'll see.

So, I got it all together and on the car (pictures to follow). I did run into the issue that I thought I might though. There is a long (~12") of silicone intake tubing that has no support. Under full throttle, the tubing partially collapses under the vacuum generated by the supercharger. It is completely fine for daily driving, but continued tuning will have to wait until I can come up with a way to provide support against collapse inside the tube....

So group thinking with Eugene (ByThaBay), I think I will grab some PVC to epoxy to the outside to provide support to the silicone tubing. I apologize for the lack of pictures.

Default Pictures

Sorry about the wait, here are pictures from my adventures. I have some more to take, but here are some.

To fix the tubing collapse problem, I bought some 3" PVC pipe from Lowe's. It has a 3.5" outer diameter, so it made it very convenient to use from the inside for support. I cut about a one inch wide piece and placed it inside the silicone tubing right before it transitions through the rectangular area of the radiator support.

Test drive showed that everything held strong until about 10psi, when based on pressure meter readings, the tube might have collapsed again.

My plan is to cut another piece about the same width, and place it before the transition through the rectangular area to prevent the collapse from happening.

I will get pictures of this piece when I complete it.

Should this work (and I'm pretty confident it will), I will make a separate thread detailing exactly what I did in case anybody wants to do the same thing.

Thanks for following!

Looks good. I'm curious to see how less restrictive it is compared to the stock filter.

What did you use to remove the metal that sits in front of the rectangular plastic piece?

I used a Dremel with metal cutting wheels for all the required cutting and smoothing. Ive gone through approximately 7 wheel so far...

Rough look at some comparison logs and where I'm at currently with setup yields very promising results.

Topz says that I should be getting 15-16 psi with my setup (he's seen more results from his kit than I have, so I trust him on this). Setup is Si impeller, 9 psi pulley serp-side, and 3.15-3.00 high traction pulleys SC-side.

Filter off datalogging netted me about 12 psi @ 6200 RPM
OLD filter on datalogging netted me 5 psi @ 6200 RPM
NEW intake setup datalogging netted me 10.5 psi @ 5600 RPM

I can't find evidence of tubing collapse in the recent logs, but I thought I saw it, so I immediately eased off the throttle.
