Whats happened to the IK noise?

[ollie_kerslake]

Morning,

A week ago I fitted a BMC CDA, but I didnt have and tubing for the cold air feed, so naughtly I was running it without a cold airfeed as I didnt have much choice. When it was like this it sounded really throuty and imprezza like.

Two days ago I fitted some tubing and ran it down near the frog fog so it was getting cool air but no it doesnt really make a sound unless your in really really low revs.

whats going on?

Cheers

before the noise was coming stricht out of the filter. now it has to travel from the filter down an idduction pipe so its becoming more quite.

same as if you would but the standard air box in but drilled holes in the top the noise from the eng would escape from there too.

the BMC CDA is basicly another air box but insted of a p.filter in it it has a cone filter this is to increase the service area thats filterd and give greater airflow = more power

simply put the bmc is now enclosed in a box (cylinder) before it was open.

thanks guys, its a shame cause I liked that noise, also I have kinda lost my 5k cam boost?

Maybe use the right foot a bit harder

I notice that its quiet unless you give it the beans and above 4K

i did mate but ou just dont get the surge like i did without the bmc, although overall perforce is better. A much better pick up through the ranges

my 5 k cam hit went/stopped when i changed the standard p.filter for a igt one. not sure why. had had to I.K on the car too and no cam hit with them too.
