Secret Life Of The Intake Manifold - Talking About

[@nastybastardatlive]

Why use the factory 4 barrel intake? It's gotta be 25 or 30 pounds heavier than an aluminum aftermarket intake manifold. They do make good rowboat anchors though.

[@UncleTonysGarage]

Because: A) Not all of our viewers want an aftermarket manifold B) Not all of our viewers can afford an aftermarket intake manifold C) Some of our viewers work with engines that don't have aftermarket manifolds available for them. D) Some viewers are only wanting to maximize their otherwise stock engines E) Some viewers are mostly interested in restoration type builds F) Some factory cast intake manifolds are excellent pieces that just need refinement G) Because making improvements to factory parts can be very satisfying for some H) The sleeper effect I) Not everyone has a rowboat to use their old manifold on....

[@nastybastardatlive]

@@UncleTonysGarage okay. Got it.

[@rockroll3983]

@@UncleTonysGarage You brought up something that has continually sat in the back of my mind. If smooth intake ports are better than bumpy, then why didn't they come from the factory smooth? I have forever thought if a car company can get better efficiency out of their engines they would do it from the factory. This video cements my theory of "not" making intake ports smooth. Voodoo sciences. Thanks for this one! and next question would be, what happens inside the head, bumpy versus smoothed? cheers

@@rockroll3983 Next time you fly try to get a seat by the wing. Hope for flying through rain. You will see the water droplets on the surface of the wing barely move, even though the plane is flying 300-400 mph. A droplet might take 5 minutes to go from leading edge to trailing edge. That's due to the boundary layer. The boundary layer lubricates the airflow of the layer above it, and that lubricates the layer above that, and so on. You want that effect inside your manifold, too.

F.I.A.T. built a factory in the former Soviet Union and they started building F.I.A.T. 124 sedans, under license there. The Soviets named the product "LADA" and reportedly built them with thicker sheet metal, in order to better withstand harsh salty winters. They dropped in their own designed engines of which were single overhead-camshaft types. The Italian 124s were using smooth-as-silk dual overhead-camshaft engines

[@daledavies2334]

Loda Ladas. :-). When I went to Ukraine in 2009, many taxis were Ladas. Some Volgas ad a few Chev Aveo, built in Poland. Virtually all were manual transmission. One Aveo had an automatic. Virtually all the carbureted cars popped through the carb. Accelerator pump probably set for minimal pump shot to save on fuel. All the injected cars had the check engine light illuminated, probably for a similar reason. They fiddled with something for fuel economy. Those guys at Garage54 are pretty inventive guys. Have to give them credit. Now the one where they cut one Lada engine in half and welded two cylinders on to another engine and did the same to the crankshaft was definately out there to made a six. They did get it running.

I'm pretty sure Smokey Yunick made an intake that made the mixture visible while the engine was running.

Back in our Boss 302 Trans Am days I remember "bench racing" in the pit about Smokey Yunick experiment with a 302 intake that had some sort of bladder in it to vary the size of the ports.

He does mention that some one bought it for a display. ?????

[@bobbyz1964]

Interesting about how you want the runners bigger than you think they should be. Stock 74 318 I'm my 3/4 pickup. Had a 68 340 intake slapped it on with a 625 Carter AFB. Yep there's that mismatch but it worked well and after some jets and rods got better mileage, made more power than the two barrel. So I score a cheap SP2P and think more mileage and low end torque! Actually the mileage and power everywhere dropped. Tried jets and rods but never got the mileage back to what the old 340 intake did. Next step is a 273 I just picked up, the SP2P will be used for a door stop or scrapped. 😂

[@UncleTonysGarage]

I've had the same experience with the SP2P and the one I have on my wife's daily driver is coming off to be replaced with a stock 340 piece. It's one of those things that works well on paper, but not in actual use.

If ya wanna see something look at the old torker 340 manifold, notice the sharp turn the airflow has to take on the outboard ports , right where the manifold runners and head ports meet ,the airflow basically slams into the side of the port

The Lada is actually an entry level luxury car. Models go between 60 to 75HP and feature all basic car functionality with some fake leather and wood interior pieces and a 2 barrel carb. Moskvich (de-tuned bmw engine) is a budget car, as it lacks some basic functionality, has a manual engine crank when your battery inevitably dies as you can't afford to drive it more than once a month and has no more than 50 hp and could barely go up a slight incline. The trabant (manufactured in west germany) is the true actual budget entry level car. It is FWD transverse air cooled 2 stroke engine, has fiberglass body, shares a single leaf spring between both rear tires, has all around drum brakes and dashboard has only a speedo. At least it has a starter as big as the ones used on Ladas (the same as the 3 cyl wartburg 353) and 4 speed transmission with a one way clutch on 4th gear (to prevent oil starvation in engine braking conditions)

[@bobkonradi1027]

There is a video on KZbin, where there's a discussion between an interviewer and Ford guru John Kaase. In it, as a part of the discussion about intake manifolds and their internal characteristics, Kaase says they drilled a hold in an intake runner, then capped it with a removable plug. After they got the engine running on a dyno, they slowed the engine down and Kaase stuck one of his fingers in the hole. He said he could plainly feel reversion, sort of a standoff. He could feel the air moving down the intake runner, then could feel the air moving back up the runner. Also, the air in the runner was very cold due to the effect of the atomized gasoline on the air in the manifold. I thought it was very interesting that there was reversion / pulsing back and from the air hitting the intake valve and then bouncing back up the runner in a "normal" dual plane intake.

[@theinsaneshecklador6598]

I just posted a similar comment.

[@blairleighton3343]

I suppose that it's like the dimples on a golf ball help it to travel further because of reduced drag, so the roughness inside the runners reduces drag on the air/fuel mixture. I remember back in the mid to late 60s, porting and polishing was a common thing. I guess maybe the polishing wasn't such a good thing after all. Didn't Richard Petty run a vinal roof on #43 once and felt it was a bit faster? Or did I dream that. Oh well, cheers 🍺
