Thinking is that the shorter stack should let it more air for higher HP#s.

The Longer 990 ADv ones result in more torque.

These will be here soon for testing.

BTW,
Air filters just showed up so I hope to start shipping out Fri and Sat.
The orginal stacks for the 990 motor (Adv,superduke,SM/T/R) are the same
The RC8 stacks with 2nd flies removed used in a airbox should give a gain starting from 6500rpm till limiter.
But it doesn't loose torque down below.

And the fun part is they cost allmost nothing, i paided 5 euro (6-7 US dollars).

example from a superduke:
