Im getting different answers from everyone i talk to about this. Does it even matter or hurt the turbo if i keep my recirculatory valve off??

 

I asked this question along time ago.The real answer is you dont need recirculatory Blow off valve on hondas its only for cars that use MAF.

 

its only for FACTORY cars that cannot expell air before the exhaust tip.

A recirculatory valve cannot hurt you. Anyone that says otherwise is crazy! Lets take pressurized air and vent it to the atmosphere.. Vs. pressurized air and venting it into the air filter.

 

it wont hurt, but is not needed and you will just save yourself time and a bit of money if you just vent it

 

At low bost pressures it probarbly does not make a diference. However as boost pressure increases it is advisable to use either a blow off valve or a recirculating valve to stop the backward spinning motion of the turbo. This occurs when the throttle is suddenly closed under load, the pressure is build up between the throttle body and the compressor discharge with no where for the air to go but backwards and minimal flow foward. With a bv or rv this pressure would be released. My choise is the rv since the air would flow back to the suction of the compressor and if boost is instantly needed (eg after a quick gear change), it is already there, thus allowing a faster acceleration.
