QTP Cutout on my evo.

Video

 

that sounds badass open

 

where is it installed?

 

that must be really loud under load? Kinda sounds like a rally car.. well almost. missing the straight pipe.. can you have it always closed or always open? (I think it opens under a certain pressure)

 

Its an Electronic cutout that is opened and closed with a toggle switch. If you look closely in the video you can see it under the steering wheel and to the left of the boost controller. Once open it says open, and can be closed at any time. Its located just after the bend in the downpipe, cutout faces drivers side.

 

where exactly in the exhaust did you put it I meant.

 

Its located right after the bend in the downpipe coming down for the o2 housing. The cut out faces the drivers side.

 

Sounds good. Can you get a vid of it when you are under load?

 

did u use stock dp?

 

Yup stock downpipe

 

I saw you flick the switch in the video.. but, and I guess I should have phrased it better.. I thought I saw one of these that automatically opened under a certain amount of pressure in the exhaust. Does this? Or is it purely manual?

 

is this what u call dump back, any leak when its close?

 

is there any gains?? or is it just for the sound

 

This one is manual only, I've also seen that one. Its operated with a wastegate actuator. I forget who makes it (AGP or ATP), that one is alot like an external wastegate , except its for your exhaust instead of turbo.

The Cutout seals really well no leaks.

The car pulls much harder with the cutout open.

 

wow, that's identical to my setup I posted before... same location, same part... even aims the same direction, lol...

Keep in mind, I've blown up the butterfly valve 3 times now and rebuilt it with parts from Home Depot 3 times now. Just yesterday, my torque motor finally decided to die on me... now I gotta call QTP and ask about their torque motors... yay.
