so i kind of got to thinking this evening while surfing ebay for quad 4 parts and an interesting item caught my fancy...
ive seen this used on RWD quad 4 setups... midgets and race cars mostly.... basically to fit a certain configuration in the engine bay or to flat out flip the throttle body around so it faces the front of the motor instead.
Upside down HO manifold
anyways, im wondering if installing this "upside down" as it were would increase intake air velocity as instead of the engine sucking the air UP against gravity like stock, it would then be fed down into the runners a bit more easily... sort of like a "tunnel ram" effect, if you will. obviously it'd probably hit the hood this way but im just throwing an idea out there.
ive seen a lot of n/a honda intake's that are angled upwards like this.. stock OR aftermarket. on n/a stuff mostly though...
who knows maybe im off my rocker.. please give input and ideas.

wouldn't we have hood clearance issues with this?
I would think the normal Quad intake would flow better since the runners flow the same direction as the TB (The air moves the same direction)... where with the RWD one, the air goes through the TB then has to jack knife backwards into the runners. I am no expert by anymeans with intakes though so someone please chime in if I am wrong, I am just going off of what I think...

Sucking against gravity... Really?
look at a Honda B18C engine. (Its a japanese only motor)... the intake mani is faced down like the HO Mani.... That motor makes like 5 hp less than the American ITR (B18C5)
Air doenst weight much so its not a big issue, except at very very very low velocities, like trying to crank the engine, heck maybe lower than that. Honestly every one but F1, nascar, and lemans just ignore that part of the equation entirely when doing intake math.

And that has more to do with how the runners go straight into the valves and ports than air weight.

The only benefit I could see to this is to keep fuel from pooling with a side-draft weber carb...which is likely why you only see this in RWD applications.
I have no signiture
As said above, this is a bad design change. You're going from the air having to make roughly a 60 degree change in direction to about 120 degree change in direction.
Paying someone to install parts and bragging about it being fast, is like watching someone bang your wife and being proud to raise their kids.
Bringing this back just to LOL @ Gravity!

brian you are a dick.
heaven forbid i try and think of ways to help my cars out you bastard! i dont have a degree in intake manifold design! LOL
i think i was on the right track for my thinking but obviously off on the theory. v8 cars somtimes like to have a taller intake manifold as well as some cars do actually improve with the use of throttle body or carb spacers, etc. and if you look at honda intakes etc a lot of them do point up so dont cut me down so badly it was just a thought, allbeit an uneducated one.. i meant well! haha
i will get you for this.

I choose the technology built for land speed records... not the technology built to save on emissions and gas mileage.
did you look at the pics? it will fit exactly the same way as the regular manifold but the t/b will be where the alternator is, they just flipped the lower piece so it faces left instead of right.
yep i did but this was like 6 months ago.. so...

Well I actually had my hood off and had my secret weapon piece sticking straight up from my tb and it made a totally difference in power rather than 90 or 60 degreeing it to the right from tb. Brad your on the right page, I get what you saying. LOL
At sea lever 1 square inch column of air all the way through to the top of the atmosphere weighs approximately 14.7 pounds give or take a little.

HMM. Math.
