Got the HKS SSQV blow off valve installed finally! The removal of the stock BOV and then install of the block off plate was crazy easy with a 12 inch extension > swivel adapter > 5mm allen head. Raised the front, took the wheel off, and you could just work it in no problem.

The symposer was a huge pain in the ass to remove. Was working in the parking lot and had a neighbor randomly come out and provide some much needed extra hands and help. I liked the symposer noise but sort of hated the ear fatigue and competing frequencies in the 2800-3300 RPM range. Totally cleaned that up but you do loose that little bit of growl. Overall worth it.

My snap ring wasn't quite installed correctly so on my first full boost pull the whole thing came out of the adapter. Drove home, re-installed, all good now!

The sound is WEIRD. I love it though. I'll have to try the other insert I have as well. Can get all kinds of squacks, whooshes, and stu-tu-tu as you want it. I'm sure not everyone is driving around playing their car and mods like an instrument but I just can't help myself. The way it holds and vents feels really good, to the point the gas pedal is just feeling more rigid and responsive. Very happy I went this route though I want to try the Turbosmart full recirc as well. I love the way that setup sounds too.

Can’t go wrong with the HKS! Symposer location makes cleaning it so much easier too.

Right? Maintenance and general inspection seems about a million times easier. And just getting rid of the heat soak from a component being turbo-mounted makes me feel a lot better. The flex of the factory piping up to the BOV feels a little meh and it really sits against a couple of other lines but honestly I feel like it’s the best configuration. Paired with an open-ish intake on the same side it really just creates a fun auditory experience though. I’ve probably put 50-60 miles on the ST today.

Definitely worth the five minutes it takes to plug it though I'm not a fan of the noise at all. That said, it was useful for the first six+ months or so when I first bought the car. I went from a five speed to a six and the additional gear is before first so that makes it more likely to over-rev the engine. By the time I took literally five minutes to plug it, I didn't need it.

Added a Redline goods shift boot, as the stocker was developing holes. Center arm rest with padding coming soon (I need spray adhesive):
I used Jeff's method and stuck it on and over the oem material and used duct tape to hold it (under the screw on portion). Cant see any of the tape.

Its not the gray or green plastic type duck tape rather a malleable aluminum material for doing say HVAC ducts. Anyhow super simple, tight and 100% reversible.

Yes absolutely but so is a symposer delete plug. Many cold side pipes totally eliminate the symposer port
Care to point me in the direction of said cold pipe(s)? Does whoosh carry them?

my tuner (Jason) wants me to get rid of it, my latest revision saw no boost increase and he thinks that’s the culprit.

The whoosh brand cold side pipe is what I went with. It deletes the symposer port entirely.

This setup? Sorry I’m new to the fiesta game and don’t wanna throw parts at it.

thanks
No worries. That’s the one. Do you have an air compressor? If so I’d suggest grabbing a boost leak test plug before you start replacing things in search of a leak. It’ll cost you $50ish to make sure you replace the right thing instead of grabbing a $150+ part and it not being the culprit. I have a few from this company and they work great.

Do you put it directly on the turbo or on the intake?

I have multiple sizes. I typically just take off the crossover and put it in the turbo inlet elbow but if I have the car of the ground I prefer to take the compressor outlet off and plug it there with one of the smaller plugs. I don’t like putting a lot of pressure on the throttle body either so I take that connection off and plug it. Also plug the evap harness port on cold side pipe.

I had a smoke machine but I used it once and it broke. Waiting months for parts under warranty. Bought one of these 2.5" adapters to try. I'll just use it on the intake. Thanks for the recommendation.

For sure. Just pressurize to 12-15 psi and spray all the joints with dish soap in water (or you can use your kids bubble wand mix or HVAC supply stores carry leak finding solution that works great)

A month or so back, I took quite a bit apart. I replaced a few coolant hoses, thermostat, and most notably the OEM air/oil separator. My next track day I was down 5-6mph on the front straight. It could be a coincidence but I feel like something is off. I couldn't find a leak and neither could my mechanic. Then the car could only hit 20psi on the dyno. They think my wastegate spring is weak but I feel like there might be a leak. Anyways going to give this a try. It's a helpful tool to have on hand.
