I have killer b headers with EWG setup on my 2020 Rex. Personally not a fan of the sound but love the performance!

All the more reason to do this bypass mod because the car will sound like a V8 when it opens

Is the EWG plumbed back into the exhaust? Mine just dumps next to the DP and it sounds crazy when it opens.

I have open dump EWG as well. So it is combined together with another open dump wastegate as exhaust bypass. Open dump everything = the world splits apart when I'm in boost

Does your cut out modulate with boost or does it open fully at 15#s?

Ahhh, spring pressure. I'm very interested in this. Too many straight piped scat packs around here.

How do you figure? He's showing gains from a less restrictive turboback here.

Yes, manifold pressure ratio (int/exh pressures) is very important but so is the delta P across the turbine housing.

You can see the dump tube just above his exhaust "cut out" in the pic.

8000 miles and this bypass is still holding up. Perfectly quiet while cruising and no leaks. Sudden heart attacking inducing scream for people doing the speed limit in the left lane then the car becomes completely quiet afterwards

Would you see a bigger boost gain with a Bypass or blowoff?

Bypass will make turbo spool quicker and push more psi

But who can turn down the pssshhh of a BOV

I don't know man... the 'Tsuu tsu tsu tsu tsu tsu' of dosing / off throttle surge sounds pretty slick.

Gotta love the tsu tsu tsu.

I get pretty nice off throttle compressor surge with my Turbosmart Plumb-Back BPV on my VF39 when I didn't used to with the stock BPV.
