Airbox Snorkel

Calling Jesse and Gregg.....

They are probably still running it since they are running stock classes and would need to keep it on.

I plan to make a map and test it at some point when I do the next round of dyno tests, but yeah, like capitalview said, it isn't a priority since almost every race organization requires it to be in for the classes that the R3 runs.

I wouldn't de-snorkel the airbox. I would just put pod filters on. Really get some air in it.

I will be running the airbox as I plan to run the 500 Supersport class in CCS.

Why More air?

If removing the snorkel gives you more air??? what is this doing? giving it more air....and you will need to find a way to add more fuel...I have done over 100's of dyno runs in different configurations and exhaust, air filters and types of fuel....I have not had an issue of needing more air....Just more fuel in several areas.....So the removal of this will give the sense of faster...because it is louder....

Where is the air box snorkel? I was going to look at my air box today to see if there was a way to modify it and found this thread. I get that the introduction of more air would require more fuel - is there a way to have the stock ECU relearn the fuel / air maps?

On a typical car, you unplug the battery for a certain amount of time, reconnect it, then start the car and let it idle for a certain time and then just drive it. I've done it with my VW's and even my Odyssey minivan (lol).

My bike is tuned with a high flow air filter and snorkel removed and mapped accordingly !! Bike runs great with a tuned HP @ 41.50HPATW

I looked at my bike today and saw the snorkel. Why in the world is the intake on the BACK of the air box?? Wouldn't it get more air pressure from the front?

I also stripped one of the air box screws - they seem to be on there really tight from the factory and are made of a soft metal. Going to have to dremel the top to try and get it off. Didn't bother with the last screw either.

So to get the snorkel off, do I need to take the seat off? I was thinking of putting a tube or a few holes on the front side of the airbox.

Yeah it's a **** design get it off ! Shame there isn't a BIG MOUTH available

Bike will need a tune tho just heads up

So the stock ECU can relearn / adapt for the extra air even up to a limited amount?

Until you strap it on the dyno and monitor AFR's under load you won't know , that said I know already first hand that the AFR's will be OFF !

Pic of the Item in question ! The idea of the snorkel at the rear of the airbox is so its not sucking hot air from the engine bay. I Seriously think Yamaha could have designed a better intake system for this bike with a ram air configuration !! I'm going to see if I can put something together to help feed the airbox with some cooler ram air !! watch this space.

About that actually Maybe you can modify the inside trim panels on the main fairing panels (the black ones) to create a ram air tunnel along the inside of the fairing to the back, bypassing the engine heat. Just an idea. Would be kinda tricky tho

There are plenty of options

A lot of work, for minimal gains. I'm leaving mine stock.

Sounds great thanks ! Just removing the snorkel opens it up a fair amount but needs tuning 100%

Well, when you make some dyno charts so I can see a total power-curve comparison, we'll go from there.

I already seen dyno results for a full-exhaust with PCV and a tune. +3-hp I believe it was. It's not worth it to me. If it's worth it to you, then go for it.

I have a question about the snorkel - I saw the rear portion and based on your pic above, is there a part inside the top of the box too? I didn't notice it but I'm guessing it must be there.

I did see that there are two long snorkels in the bottom of the box below the air filter as well. Are those tuned as well for something? I'm guessing one for each cylinder maybe?

With the snorkel removed, couldn't you drill some holes on the front part of the box and refit the outer snorkel onto it?

Looking forward to seeing what you have in mind for a ram air setup!
