You're Gonna Need a Bigger Plenum...—Engine Masters Preview Ep. 51

Well, maybe. This time on Engine Masters, presented by AMSOIL, we dive into what effect changes to your intake manifold's plenum volume will have on your motor. We want to know if all of the Internet's theories about big boost, big cubes, and/or big rpm needing bigger plenum volume really hold water. Will all of that increased volume really turn into increased power production or are you just creating hood clearance headaches? Watch as we go from straight out-of-the-box to out-of-the-bounds-of-sanity with this plenum volume comparison. #EngineMasters

Come back to youtube where y'all belong. Where it all started!!!

[krover]

Probably the most uneventful episode yet.

[MrTnia]

Nope, still not getting your membership. Shame this is just a money grabbing scheme, you have more than sufficient paid promotional content / ads, my mulla aint joining in.

[Anthony_Pell]

Still not willing to pay so just come. Back to YouTube.

I went from a stock Tuned Port Injection long tube intake runner making a lot of low end torque...
To a Holley Stealth Ram intake with a large plenum and short runners.
Love the latte... If memory serves me correctly I think it made an extra 80 hp on a lean AFR

Just watched this. Great stuff 😀😀

Just a thought. That lower intake manifold. The air going into each cylinder may be dictated by the runner size. So no matter what size the plenum above makes no difference.

If you look at a V8 Supercar engine for example, They run independent runners with a throttle butterfly on each cylinder, but a massive air intake plenum above it.

I would love to see that same engine tested with eight throttles and see if the power is different.

We need more real world stuff like this current stock or slightly modified motors like 5.3 5.0 5.7 stuff most people drive today and want to build for everyday street applications

They would make so much more money if they brought some of these series (like the ones that did really well) back to YouTube. Throw in an ad slot/season sponsor slots and then some of the other shows/newer shows BTS etc on the MTOD program.

The 318 magnum would be a really good test bench for this expirement.

I subscribed to motortrend, I feel it's worth it given all the content besides roadkill. I enjoy the tech in this program and hope it sticks around. I feel like this being a relatively new episode that it may be in jeopardy barring interest.

I also miss the short how to segments on the on demand channel.

They don't show you the results.. They want

[johnogo]

Will that setup work with a 69 Mopar 383 big block with roadrunner cam and 11.5 to 1 compression ratio?

[mudpuddle]

Dammit! I really want to see where this goes... but not enough to go join some pay-per-view site.

[cryptorchildx]

I hope this was a joke episode for Halloween, because I love this show and this episode seemed like a joke. I thought it would have good insight like the carb air filter episode, where we learned a salad bowl can add a few hp's, instead this episode was short and did not really teach anything.

[mrb.]

But is it plenum volume or the distance from the plenum roof to the intake runner that's affecting it ?

[BBb-hsud]

I'd like to see an episode about head modifications. Like port and polish, different cuts, dimple porting, ect

[MADMAX]

Can you guys run a test with an aged and clogged catalyst to show performance sensitivity to exhaust backpressure?

[drewsharpe]

What LS heads come stock with no freeze plugs?

[caseywest]

That’s crazy I can’t wait for the actual video to explain this and how to get your hands on it.... let’s go fellas I’m not getting any younger

[CraftsmanQuad]

One thing I really wish the app had was the comment section. Lots of really cool discussions down here about different tests and tweaks they could’ve made to the tests they did
