who else here has done it? i got bored the other day and made a delete plate for my WRX and i was both impressed and disappointed about it.
with my BPV working normally, in gear on and off throttle is very violent if i am not smooth with the pedal. with the BPV blocked it is very smooth no matter how abrupt i am with the throttle, i quite like it a LOT. BUT!!! basically between shifts the RPM's hang/drop slower than normal so it causes me to get on the throttle/off clutch weird. so i would have to shift slower to make it smoother. its a badass sound, but that throttle hang alone is annoying enough to want to go back (even though i was going to anyway). im sure theres ways to get around/fix this. but the feeling when staying in gear geting on and off throttle was really nice/interesting.
the DBC 02-05 WRX's with the 16 bit ECU's do not have this throttle hang issue, i believe it is something tuned into the DBW maps on 32 bit ecu cars (04+ STi, 06+ WRX)
next time i can play around in the dirt i will try it both blocked and normal to see how it is.
i will also say, on a VF39 i dont think i would run it blocked all the time because of the potential to bend compressor blades (have no research on this at all) but on bigger turbos i would run none at all full time. but what do i know, im also going to be running a VIPEC V88 and anti lag...
heres a video i have of it. its kinda hard to hear but you can. these videos were done with the windows up to hear the turbo spool and surge better. the surge is audiable from outside the car. im running a stock intake with snorkus removed.
