"Strange" low noise at 3000rpm
My 2001 RX7 run fine...
Start without problem cold or hot.
But I have a question.
When I push gas and hit 3000rpm for a time that is around 1/2 sec i hear a sort of "Bwhooooom".
During this noise nothing strange happen and car continue to rev up without esitation.
Any idea?
PS
Car is engine stock except for Aftermarket air filters

I have no CAT atm and here emission test is not a problem..
I can solve this problem with
1)Stock Airbox
2)Remove Airpump
Q: the noise problem can be solved with AIR PUMP deactivation or i have to physical remove the pump? (and I need a shorter belt?)

im sure you can deactivate it, but i physically removed mine. you can do this by installing a pulley kit, it gets rid of the the belt that runs to the air pump. i went with a greddy.
