Difference between air box and big filter/heatshield LCR

[Bouncerbeater]

I've swapped out my JR filter and heatshield setup to a stock air box and filter on my LCR due to trying to keep the noise levels acceptable for her indoors. Have done logs before and after and am getting a drop from 215g/s to 190g/s
I knew there would be a drop but this seems rather a lot.
Anyone have experience of this ? Is this the right kind of levels ? To me, approximately 30 bhp seems a big difference between the two

Try again without the snorkle intake. It does seem like a lot!

 

[Bouncerbeater]

Was thinking that as it looks fairly restrictive.

You reading that right? The readings you posted up a measured air flow values not bhp

 

[Bouncerbeater]

Yes, just using the recognised method of dividing airflow by .8 to give a rough bhp

Ok, new info learned I have!

I logged my big filter back to back with airbox and gained something like 11g/s with open cone. no real difference in noise either

In my case the open cone is pretty loud. Mainly turbo intake but stock airbox is much quieter. If only I could have somewhere near the performance of the open filter with the lack of noise of the airbox. Nirvana I suppose

Open cone is also pretty loud yeah. I want to have airbox back as well, but my SFS tip is a tad to short to make a proper join with the MAF body.

So for now, open cone haha (with music set a tad louder)

yep

seen the same on dyno

hence why when asked oe airbox vs open cone, for power, open cone wins

Perhaps I will keep airbox for day to day then swap over back to cone filter for fun blasts etc. good job it only takes ten minutes
