Has anyone ever done anything with ram air intakes - on anything ? Need some advice!

EXPECTATIONS VS. MONEY

I really don't get how you can not 'try it to see' (as in proving a theory) to see if the theorem and maths aligns.

Eg ... 'Oh I think a wheel will role along' ... No wait on, we won't 'try it to see' first before we go into production .... Who the hell would just chop into something all guns blazing without trying out the basis of the theoretical ?

I've already stated my opinion of this sidecar thing ...... I'm curious as to the amount of money you think this is going to cost ...... If less than 6 figures, you are wasting your time ....... and since we are only allotted a certain amount - I think you would happier riding and enjoying life ..... Mike :thumbup:

I see these all the time at the track aka NEVER...A windmill generates power from free air. The vehicle can't do it for free.

Next silly question ...

Has anyone ever done anything with ram air intakes ? Obviously asking because in all the years of tweaking and playing, I have next to no experience with them.

However, thinking I wouldn't mind crossing a semi forced induction ram air intake with a particle separator style intake, that are mainly used on aircraft. ( ... think about a normally aspirated engine - then go to the other 'extremes' of turbo or super-charging, ... now back up the train to about half way between these two extremes and there sits what I envisage)

As an aside, particle separators, I'm very familiar with from my days of working with rotory engines and helicopters (Allison turbines especially ... And I see when I began 'googling' this stuff again, low and behold both Polaris and Can Am are all over it for their adventure off road series of turbos and the like ... bugger me ... C'mon BRP ... catch up with the Spyders yet again ...

So much for that idea …

youtube; cbGWgvJN1_8] youtube.com/watch?v=cbGWgvJN1_8[/video] … apparently not … ha ha ha … back to the drawing boards … Oh well … The ECU should be back from Monster early this week and that will be amazing no doubt!

There isn't much of anything you are going to "insert" in the intake tract that will do anything other than impede airflow. If you do some math ( (Displacement) (RPM) (Volumetric Efficiency) (Pressure Ratio)/5660 ) to determine CFM rates for the engine you are gonna see that a 1.33 liter engine spinning at let's say the midpoint of our rpm range, 4K, with a standard 90% VE figure will ingest air at a rate of 84.59 CFM... And pretty much double that at 8k. Even at a modest 2k it will ingest at a rate of 42.29 CFM.

There is more to be had by cooling the intake air charge and removing restrictions in the intake tract (air filter etc). You have to be careful when enlarging the intake piping diameter when using a MAF type system as this will change the MAF readings to the ECM. You can get away with it if you are using a Speed Density System up to the limits of the maps' ability to self adjust.

To reinforce what Hypureone said; I read a well written tech article (years ago--I'm sure the laws of physics haven't changed) on the efficiency of sport bike ram air systems. They instrumented the air pressure feeding into the air box from the test bike's factory ram air scoop. They got no pressurization at all until well over 100MPH! At around 160MPH they had a fair bit of pressurization, and estimated it was good for an additional 11HP over the factory rated static HP.

If your objective is to duct additional cooling air into your radiator/oil cooler etc--that's pretty feasible. But if you're trying to pressurize your intake for additional HP--that's a Unicorn; unless you've got strap on rockets on your Spyder to get that aerodynamic brick up to 150+.

You could always try several leaf blowers to pressurize your intake. :joke: If you do---be sure to video it and share!

I've seen ram air extension intakes on the Hayabusa bike but I've never heard anyone brag about power increase.

A cold air intake would be nice but my ice cubes only last for 30 min or less :-(
