Airbox or separate Filters? An age old question.

[Nickj]

A little bit of my retirement package is going into a 748R, savings seem a bit pointless (possibly an on-call osteopath too) Now they had the bigger airbox which fits into the frame which isn't the regular trellis.
Probably a good idea as the motor is a real air gulper with big valve lifts and the above intake shower injectors would work less well with even more turbulent air.
CV's do prefer more constant pressures so a box makes a bit of sense and the volume can be used to do a bit of pulse tuning but it's maybe more effective looking at the stack length and clearing any steps in the intakes above the carb or injectors.

Something like this;



EVR large airbox with TPO 'Beast' velocity stacks on my 916, shame you can't see it when the tank's on because it's automotive porn...

I have the TPO Beast stacks on my S4, they are huge and only just fit but do give a little bit more midrange torque.

I have read many times in various places that the best setup for the 748/916 bikes is either the standard airtube filters or those BMC ones that you have; any over the stack filters mess up the airflow and also reduce the airbox volume. I have gone for the standard DP carbon airbox and DP airtubes which will take a flat panel Powercross filter. Would probably get another set of TPO beasts for that too eventually.

Similar to mine but shorter stacks, that would go with the higher rev capability and of course more bits to blob in the fuel.



Not a pic of mine, I'm still reading through the Ducati workshop manual to get the hang of how it's stuck together and comes apart.
