Been looking at some air filters and the lovely chaps in Aus that make the ones I am interested in, insist in quoting the airflow in cubic feet per minute. My brain is tiny and I'm crap at maths, can anybody give me a rough estimate of the airflow for say 150 bananas in cubic feet per minute?

They offer 300, 400, 600 and 1000 CFM versions, so I need to work out which size to go for and then try and find one to suit my application...

Thank you please.

Even when boosted, a smaller filter will generally work fine even when smaller than n/a airflow might suggest.

K&N rate theirs at something like 1.8x n/a airflow for boosted.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Andy how are you going to fit it under the bonnet?

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

I'm going to bolt it to my 'carb'. They come in enough variations to find something that fits OK.
