Interesting...thanks for sharing.

Notice header on that article, it say theory.
In real world you may not have perfect air box and your bike may run better without it. Only way to know is not by reading articles but to try.
You can take complete air box of and put individual filters on carbs, tune it to compensate for change and gain power everywhere and have better running bike.
If it was simple calculation all bikes would run perfect

Yes it gives the theory behind airboxes and how they work. It doesnt say you cant modify them. I posted it up because alot of people dont realise how they can or do work.

Yes but by doing the math you can reasonably work out what you could expect to gain or lose before trying it

How you going to calculate your gain by removing air box?
How you calculate how much hot air from radiator enters snorkel? Or how much oil mist enters air box through crankcase vent.
My point is you can't just say that removing air box will take away or add hp by reading article on air box principles. You have to test it, it is only way.

How about sticking to subject and showing your extensive dyno tuning without airbox lid?

Well I did not do the dyno runs... But, I trust the person that did the dyno runs...

If you lose power on the dyno... Do you expect to do the same thing to other SV650 and have different results?

Sounds like personal problem

Oh yeah... I forgot you do not trust dyno results...

But, if you have a better way to make a bit more power out of an SV650... Share what you have!!!

Luis

I never said I don't trust dyno.
However I can say I don't trust what you say
