If I dump my BOV to the atmoshere, will it make me run rich between gears? I have not seen it yet. I have A/F and EGT.

Is there performance to be gained? because of the loss of air making the mixture richer and killing performance?



Should I try to get the BOV air back into the intake tract somewhere?


This is on a custom ported JSpec twin rotary turbo.

 

Ditto on the gas mileage.Your prob losing respool time also.

 

you guys are aware that it i8s a twin scoll turbo, nothing close to what you run. I make full boost @ 3000.

You also said losing Gas mileag without getting back into the system? is this becuase the ECU adds more gas, I would think the o2 reading would lean it down to match the lost air that was there during the MAF reading which was sent to the ecu, whihc is in 100% control on these RX7s. They also learn mods and adjust acoordingly. for optimum performance.

 

During a shift the mettered air that has given the ECU the signal for X amount of air being in the motor . BOV opens , no longer the same amount of air for fuel rich condtion occurs , slight spool degrdation .

Its really not worth it to vent it back IMO . The gain wouldnt be noticeable .

Why keep the stock AFM anyway . Haltech or Microtech is the way to go the power gain made by switching to Speed Density is alot .
