V layout with reversed intake and exhaust
V layout with reversed intake and exhaust
(OP)
Consider a reverse of the standard locations of the intake and exhaust on a V layout engine.
Is it not practical to have a significant portion of the intake tract running up instead of down?
I'm not asking about changing an existing engine etc.
Thanks for any thoughts on this.

If all possible ways haven't been tried, the unexplored volume of the solution space is small.

I don't recall seeing an engine with slanted bank(s) where the intake was on the underside of the slant.
It doesn't mean it hasn't been tried of course.

Also, I recall one of the Gurney/Eagle 255 engines going into a Bonneville door-slammer a bunch of years ago.

Additionally, if you were at Goodwood this year, for the first time, Ford Museum had the 1965 Indy 500 winning Lotus of Jim Clark on display. Driven by Sir Jackie Stewart wearing a "Jim Clark replica helmet". I think this was the very first time the car had been on track since winning the 500! ( Also that year was the Lotus/Ford of Dan Gurney...Just another example of "reversed layout".)

I could go on, but suffice to say, it's been done long before any of us were a thought!!!

There are outboard motor Vees with the "reverse flow" configuration too...

We've covered the technical features of this smooth-running 3.3L block in the past, but since this Yamaha has an unusual design that's particularly well thought out, it rates a short review here. It uses a 60-degree V block that employs reverse flow for the intake and exhaust systems. The intake feeds fuel and air into the engine around the outside of the V, and the exhaust is routed from the center of the V into the midsection leg and lower unit. This is just the opposite of V-block automotive engines, and results in a more effective and less restrictive exhaust system that's perfect for a high-performance outboard.

In Indy cars and F1 it is possible to exhaust straight out the back at above engine level, so the pipes over the top between the valley removes heat from the chassis better and makes 180 deg exhausts a piece of cake for cuniform crank engines.
Up draught intake is no problem for dry systems with port injection, but there where inherent problems with up draught carburettors that where popular pre about 1920.

There's some inventive tech from back then to get around problems that we'd consider trivial today.

I am 100% sure there will be other gasoline engines with a similar arrangement, in the market place, in the not too distant future.

I can certainly see the advantage in turbo applications.

The difficulty in routing the exhaust is, in a passenger car, a major consideration. With the requirement for two 90deg changes of direction.
Another associated problem is the placement for the catalysts which for light off reasons need to be as close to the turbine exit as possible.
Also the placement of the turbochargers in this area, underbonnet, is not ideal for thermal management as there is not much airflow within this area.

It has a powerglide trans. The last time I saw it he had a vice grip on the shift arm for a shifter!!!!
The radiator is in the rear mounted under the pickup bed. He uses water pipe for the long runs to the motor.
It sounds strange but it runs.
I just got a picture of it from our club photographer. If I can figure out how to post it I will later.
