Question about side scoop?
It’s no secret that our side intercooler intakes sit very close to the body and not further out to grab more air for enhanced cooling. Porsche corrected this with the newer turbos by sticking the intakes further out along the body.
My question...
is is there any other source out there for a larger air duct other than the Joe Toth (I appreciate joes work and the things he does for the community but they’re just too bulbous) and the Manthey sets (perfect but god damn with that price tag for something that’s so small))? For the amount of options of rear wings, side skirts, bumpers.... why isn’t anyone maybe looking into this area that’s crucial to the performance of our cars? This post is more or less rant now that I think about it but whatever.
Anyone have a source for 3D printing to maybe tackle this?

I follow a handful of 3D printing pages and if you contracted someone to do this you’ll probably be close to the same cost as the Manthey product. There is a place to get them for 750 ish but still a high price tag. However while considering to use 3D printing I would also be looking at the duct way from the scoop to the smic. You can only flow so much through a certain space. I haven’t personally had a look of the routing through the quarter panels but I would imagine that there is room for improvement.

The turbo cars are pretty sensitive for timing with the relation of the IAT. Keeping the temps in check will keep you in the timing area you want to stay in. We know aftermarket smic units can help as well but I believe some conditions still can’t be controlled just by them alone.

If if there was some type of additional way to draw more air across the surface area of the coolers, I think we can all agree that it would be a great thing, no?

One factor to consider that many people don't realize- the stock inlets function more by pulling air through the coolers from venturi created by air moving across the outlet at the bottom of bumper than by air entering on its own through the upper inlet. The air flowing across the lower duct creates a vacuum in the inlet since the air is moving faster across the bottom than inside the lower duct work and it sucks air through the side scoop. Hard to explain it correctly. Bigger ducts help the venturi pull more air through.

There’s been plenty of data between Toth and Manthey of them dropping intake temps between 10-40 degrees. I may be off a little but close for discussion. If the Venturi effect is there then why not place puller fans there?

Puller fans would probably make it worse... theyre an obstruction.

overall efficiency of any engine is a must right? I doubt during average street use, but for a acceleration type situation (on ramp, traffic light, etc) I think the added air being drawn in will help the engine.
Im not a engineer of any sorts. I own pizzerias. I could be talking out of my butt, but just overall I made a observation

Efficiency is important, but IMO there first needs to be an indication that something isn't efficient enough in its current design. I think for street use, a stock 996 Turbo has all the efficiencies needed to produce enough acceleration to manage any situation you reasonably face. If there isn't enough acceleration available for what you're attempting to do, then I would suggest you just not do it.
