GR Corolla Gets a Blow-Off Valve Upgrade! 

Save yourself time and hassle by removing the windshield wiper cowl / support tray. You will have a little over 1ft of space. Enjoy!

I’m loving the gr content but I think what would’ve been nice in the videos for the intake and the blowoff value is if you should it before and after

Sounds mad! Love the bit of surge 👌

Sweet! One thing I expected is that this would have been much more aggressive-sounding straight out of the showroom given all the hype and drone footage of it in action.

I love that turbo noise so bad, such a good eargasm! But I heard many people say this sounds overtime would harm to the turbo, is that true?

The turbo flutter sounds sick. Is the blue spring the one you ended up using? And is the dump valve link in the description the same one used in the vid? Might return my turbosmart for one of these.

Question: I was thinking of the Forge turbo inlet (only) for the GRC. Do you think it impact the stock diverter/dump valve since more air is going through from the Forge turbo inlet? It would be primarily for sound, and minor HP as secondary. Also, I was wondering if getting the Forge turbo inlet would give CEL. Would appreciate feedback.

Excited for this new STI… GR Corolla 😅

Damn this sounds so good

Any issues so far with the dump valve installed?

That silicone coupler is going to ripe open with all that boost over time.

do you need a tune if you just add the BOV? I would love it on mine, but don’t wanna cause any damage.

So does the bov make the sututu noises or something else?? I’m trying to make mine sound like that

Any update on how it’s doing? Running good??

Enjoying mine

Did you need a tune with the BOV?

Got that same kit with catback mbrp doenst do whistlers

Do you need a tune for all of this ?

Any videos of the recirculating bov??

That sneezing would get annoying, with less performance than a recirculating valve. Downgrade.

Dude, who usually takes off your wheels? Why are they ground down to bare metal near the center cap and definitely into the lugs area. That’s not a good look bro. No offense. But wow. Who is that careless
