Epic!! Thank you for all the time and effort that must’ve gone into this video, super cool to see the various effects. I was shocked to see how little the 45° metal bend impact the result. For a V2, please consider comparing different filtration options, eg. those metal mesh stack filters that sit over the opening of each stack vs/ meshes that are mounted between the stack and the body, vs/ those individual foamy thingies that sit over each throat, vs/ K&N DCOE-style filter boxes with the big shiny plate where you want the air to come from, vs/ none. There’s so much folklore about the various filter options (“oh, these will kill air velocity, try these other ones”) that it’d be really nice to get some real data.

Usually, on normal induction engines (particularly older ones), the best ram length will be equal roughly, to the length of the induction travel (i.e. the distance from the venturi to the cylinder). Massive radius bellmouths will always flow more than any other form of intake. There are some exceptions to this (like the A-series siamese port heads), but its a good general rule.

The only real remaining thing to test, is getting a linear actuator and trying to have variable runner-length on the same dyno-run, and figuring out what rpm which runner length is optimal, and if variable angle would be beneficial too. As the Yamaha R1's come with "stacked" trumpets that vary the runner-length to some degree, it has some impact obviously, but what remains to see is at what rpm the intake-pulses swap to purely wanting air-speed and if it changes back at any point if load is increased

In 1965 my SCCA sponsors modified a 356C 2600 SC so much that it had to run in E Modified class. It’s Solex 40 I-II carbs were topped with just duplexes airhorns - the trumpets. The car finished third in the Marlboro 6-Hour race. Conventional wisdom then was for short intakes, long intake runners and a short exhaust if you wanted high end power. You reversed that for more power in the lower RPMs at the expense of absolute power.

I posted this in a group it was shared to It's a very interesting comparison. Everyone loves to argue on the internet without hard data, and everyone has a "best" set up, but it's not always ideal or practical to follow them. I would love to see the stock intake setup for a true baseline. Then maybe an enclosed airbox too with a single entry. We’re all aware 10kw is a big gain in these engines, but I’m not sure my (inexperienced) butt-dyno could tell the difference between a lot of the configurations and would go with what’s most easily accessible, fits in the engine bay (peksy brake boosters!) and fits the budget. Thanks for doing a video like this

Remember also, that the travel of combustible mixture through the intake will change from ramming. David Vizard did a massive test of the flow pattern, and found out that even on increased flow from the inlet, the travel path of the mixture changed, sometimes causing backflow in recessed areas of the intake (like after a sharp turn). The atomisation of the fuel in the mixture also changed somewhat from the changes. More power wins, but its interesting to note these things.

Hey, yes this is basically what my normal intake is. Being the one at end of vid with the air filter. Total length is 185mm, but has slight taper and decent sized bellmouth, so it acts closer to the straight 165mm pipe rather than the 185mm straight

Bellmouth shape changes the reflection point of the open tube and different Bellmouth forms will mimic different length pipes. I think you will find a stronger effect and more torque area under the curve with smaller diameter tubes.

Nicely done tests!! Thanks for your efforts...very instructive. I know you don't really have room for it, but building a Helmholtz tuned intake box could help the bottom end and flatten out the torque dip you're seeing in the midrange. We've done some testing on SV1000 Suzuki's and with stacks and pods they lose midrange and gain a little on the top end, but with the stock airbox it boosts bottom to midrange with little top end loss. You'd have to go above hood level to experiment with this concept, but thank you for posting up all of your tuning videos.

The correct diameter ram pipes for this engine will be around 41 mm and about 150 to 200 mm long. when you go larger in diameter as the 51 mm are the velocity of the air is so low there is no change in power as you change to a larger ram pipe. I know everyone thinks that diameter has nothing to do with it but I have dyno sheets to prove my point. We put a Toyota 1.8l on the dyno and tested a couple of different diameter ram pipes and got a 60 percent lift in power at 5,000 rpm for a decline of a couple of KW at the top end, If you want I can send you the dyno sheet and you can check out if what I say is correct or not.

Interesting research from physics point of view. With different tubes you change out-coming gas resistance: velocity perturbations from turbulence and etc. In ideal conditions you need vacuum cleaner for exhaust gas sucking. If you want to increase the power in some RPM range, you need to calculate intake air velocity and find right geometry for maximum turbulence. i'm think, you need create some mini tornado with rotating shape air flow. In centrifugal process, heavier fluid particles goes outside, light fluid particles concentrate in the middle. Easier fluid particles is smaller and more efficient became in to energy. Good luck :)
