designed for:

2nd harmonic at 9500
3rd harmonic at 7300
4th harmonic at 5500

plenum volume is ideal for an engine displacement of 2 liters

throttle body is 90mm (Q45)

 

What kind of numbers?

 

its only tacked together and a before and after will not be possible (at least on my car)

 

I am surprised that the stacks are in the middle of the chamber. I would have presumed they'd be on the "floor". Why is that?

 

I'd like to hear/be informed about this.

 

having the bellmouth mid plenum with a full radius bell allows air to be pulled from underneath the stack instead on only directly above it. This means there is a lower instantaneous pressure drop at the runner entrance.

 

thinking the exact same thing....I can't see how in the middle of the chamber would be better.

 

Okay?
One more time, this time in english.

 

Looks like a serious mod.. just would like to know what exactly it achieves.
TIA
