The taller plenum requires more taper in the runners to match the same cylinder head port. Taper influences the wave tuning and that could be part of the difference you are seeing. It also looks like the runners might be shorter on the new Victor JR. The tall intake looks like the Super Victor 340 intake.

Then evaluate the mixture across each cylinder to check for lean/rick conditions with 8 o2 sensors. Of course the EFI will apply the same fuel to each cylinder but does the manifold supply the same air ?

Yeah it doesn't really make sense. Same manifold model except for different years and looks overall the same (height and runner length), but big difference in power. Yet the mods he showed, like radiusing the top of the plenum, and port matching barely do anything?? 🤔 The Victor Jr ports are quite small as cast. My heads are matched to a 1205. Was going to match the roof and straight side of the intake ports but guess that doesn't even matter now? And that intake being LARGER than the heads "should" fall on it's face but this is another example of that not happening.

Have heard that the intake should flow more than the heads, BUT, what about that huge lip?! Was saying that port matching can't mean much seeing this. And, I wonder if having the intake be a restriction could help in certain applications. Like helping to give more driveability and throttle response for a smaller engine with large heads (like a 355 with 230cc heads). Or does the higher flowing intake apply across the board in ALL applications?

Yes I'm aware of a combo having to be matched, but did wonder about certain things that could "crutch" certain combos, like the large heads on a smallish engine. But it makes sense to have that charge right there when it enters the large ports and build some velocity. I just thought a way large intake would LOSE velocity on an engine "not big enough".

Great video Eric! Just goes to show you if it ain't broke don't fix it. You should show your Victor Jr results to Edelbrock, maybe they will go back to the original. Concerning your LS comparison, does it include putting a set of 15 degree heads on your dyno mule? That's the only way to do a true fair comparison. If the 23 degree heads can keep up, imagine what 15s will do!

@stevenbelue549611 ай бұрын
Could the rolled/blended edge only gaining 2 hp have to do with fuel atomization. I would think it increased flow dramatically but it may have hurt atomization. Thinking that sharp edge helps fling any droplets or unatomized fuel back into the airstream, after blending maybe it just clings to the wall and follows the contour and doesn't get introduced back into the airstream and reatomized. Just guessing
@dennisrobinson800810 ай бұрын
I heard about this test elsewhere. I dont' believe Edelbrock didn't make gains with the new product. What i "suspect" is the port exit at the manifold is a different size/shape and perhaps the "super victor" has the intake charge hitting a "wall" with the head ports protruding into the air flow path, whereas the victor jr have a better port match out of the box.
