Fiesta ST Symposer delete. Boost test and sound.

[@terrypotts2802]

Hey Steve, jubilee clips don’t distribute force evenly around the fitting - they tend to pinch either side. Proper hose clips (like the one that broke) do. It could be you’re losing that small amount of boost because of this. If I were you I’d swap out the jubilee clip and repeat the 3rd gear pull. Great video BTW 👍

[@ducky-o7y]

Really enjoying your videos, fellow ST owner. You have a lovely family and it makes a refreshing change to the other FiST channels. Also my old tutor was called Steve and he was welsh, do you know him? ;)

[@Sparkplugsteve]

Thank you very much for that comment. yes i know him very well haha

5:48 Sounds like Darth Vader is in your engine.

[@PaulinhoThompson]

Interesting results - "like a glove" :D

[@davekent9770]

You need to block off the end of the pipe leading into the cabin otherwise you’ll pick up all the random rattles and noise of the engine bay. I found a suitable sized bottle cap and blocked it off with insulating tape and cable ties. First attempt fell once and that’s why I know it makes a massive difference.

[@Sparkplugsteve]

Thank you. I did wonder what to do about that pipe.

[@MG-ko6jf]

Interesting. I don't have a boost gauge in my Fiesta ST. Ripped the symposer out and plugged the line with Dorman 02600 expansion plug. I like the quieter cabin. It also feels like throttle response is better and it gets up to speed just a bit quicker.

[@BensCoffeeRants]

There's a lot of variables when testing boost, engine / intake temps, humidity maybe can affect it, so best to test multiple times, but I think you should start by making sure the symposer delete plug is nice and snug.

[@jeff7461]

Sounds alien coming out of the garage!

[@bluntyr5gtt]

not sure if you read my comment on one of your other vids but i mentioned doing this its a complete no brainer, along with quick shift and rear engine mount :), glad you have done this though

[@bluntyr5gtt]

i also had a real pig getting that clip off ended up using a set of pipe grips haha

[@Sparkplugsteve]

Hi bluntyr5gtt. Yes I remember your comment and took it on board. I plan to do the 2 other bits soon.what brands are you using? Thanks for watching and commentimg.

[@a1b3do]

Love the begrudging family cameos

[@sugarsaint]

johnny come late, but as an owner of 3 turbo'd cars todate - imo its simply a case of your turbo having to produce less boost for the same about of HP without the symposer. It's like having a free flowing exhaust - your cars boost will drop off completely but produce exactly the same power. It's when you turn the boost back up to what it was that you'll get the full effect of the upgrade.

Very interesting video and well put together. I have a 2013 Focus Titanium X, similar engine as yours. Great to see somebody make a video on it, keep up the good work.

[@Itz_Miaxoxo]

Gretsch video, I purchased the symposer delete kit for my ST, with the agency power exhaust system I thought it was a better combo to delete the symposer so I can hear more of my exhaust sound.

[@mightyrs4221]

Maybe an exhaust, I see the kids so don’t wanna say straight pipe , just a bit of noise up revs, good video

[@Sparkplugsteve]

Hi. I have thought about an exhaust but it would need to be a quiet one to avoid the drone. Iv read the standard exhaust is good for 300bhp plus so will probably leave it along and do intercooler and sport cat so I can go for more power. Thanks for watching and commenting..

[@DutchMiester77]

Can you do a symposer delete with a blow off valve adapter .

[@roders2011]

myth busting top lad.good vids good work. quite enjoy watching the vids keep up the good work

[@96mivec]

Atmospheric conditions like air temp can effect boost pressure. I noticed first test was raining so air was possibly denser on that particular day.

[@Sparkplugsteve]

yes i think your right.

[@96mivec]

I had a boost controller on an Evo for years and had to turn boost down as the weather got colder 👍🏻👍🏻 Enjoyin the series pal, love that ST

[@Toby_the_Glen]

Although the first test with the symposer was done on a damp day. Colder damp air gives a better 'burn'. Maybe try it again when it's raining?

[@joebar924]

you should change the hose upstream of your ITG admission, there is a lot to gain at this level because the original one is very restrictive.

[@samporter4882]

[@ROFLzSALMONz]

[@Dungeonbrewing]

Did you ever get to the bottom of why it appeared to boost slightly lower with the symposer delete?

[@RedCastle335]

What kind of blowoff valve do you have? It sounds amazing.

[@Sparkplugsteve]

It's standard with just an air filter so it's louder

@@Sparkplugsteve ok thank you

[@GabrielSTEFAN943]

Do you think this could be retrofitted to a car that doesn't have it ?

[@aydencaldwell2472]

What’s giving you the flutter noise ? Heard folk getting it from turbo smart dump valves but also sometimes just from an ITG

[@diegudr]

Cant you just unhook the hose, rubber band a sock around the end to keep dust out. Then rubber band a sock around the symposer? I know that sounds ghetto but would that produce the same result sound wise? I just thought I might try that temporarily until I have time to do what you did. What do you think?

[@Nyziko]

Maybe the bung is leaking boost around it's edges? Ah well, if not atleast it's a lot more quiet now hopefully. Sometimes i think it's too much with the drone on a little uphill highway.

[@Sparkplugsteve]

It seems ok now. Maybe it was a air temperature difference in the day..

[@uTheJoKeR]

What size clamp did you use?

[@mitchiranger]

Is it me, or did it sound the same? Must be a thing to which you have to be in the actual car to experience properly, instead due to audio on a video. Great video either way, informative :) cheers

[@Giannis_Cooperakis_AtWork]

Were the two runs (before and after installing the symposer) equal in terms of rpm? If so, although it doesn't hit the 21psi, it maintains much more boost at the top end.16 versus 18 psi is i'm not wrong.

[@Sparkplugsteve]

They were both 3rd gear pulls from about 2000 rpm up to 6rpm give or take. I shall take a look again. I only really looked at peak to be honest. Im still yet to check for a leak but the car drives great. Il watch the vid back now to see how they compare again.

[@CarRambles]

Did you ever find out why the symposer delete caused a drop is PSI?

[@Sparkplugsteve]

i didnt really investigate it other than checking the bung was tight. car feels the same so put it down to different temperatures between runs.

[@vicvidzz6575]

It could be different Temp outside when u did the two pulls since when u have the symposer on it was racing so the air temp was cooler which means more boost

[@zrsfocus8888]

Could be dropping boost because of the recirc and actuator mate. When I had mine with cp2 on the dyno it peaked out at 228bhp on the first, but 2nd it was 190ish. Haven’t had a problem since getting a forge recirc. But from day to day use, you probably won’t notice it that much as you say when driving it 👌

[@BensCoffeeRants]

A friend and I tried and couldn't get my symposer off, what did you use to help you get it out? WD40 or something similar?

[@geekuyujr8376]

What you got on it that makes it sound like that????

[@Sparkplugsteve]

It's the map. It was a early peron 1+ that fluttered a lot.

[@danwilliamsr538]

[@cjmackay9804]

Was this car mapped when you got 21psi?

[@Sparkplugsteve]

Peron stage 1+

[@cjmackay9804]

Ah ok my wife has a molten orange st running cp2. The boost gauge hits 21 psi no problem but my standard race red st only hits 19psi on boost gauge. I guess a mapped car produces better boost?

[@Nyle95]

@@cjmackay9804 The molten orange colour gives it a few extra psi

[@meddylad]

The symposer was an absolute bitch to get off mine.... the clip is real hard to get a grip on and even with the clip off the symposer wouldnt budge (tried WD40 but wouldnt shift)...it seems like it was glued inside the rubber pipe. In the end and with my opinion now, I just used a stanley knife to cut the whole symposer off ( only need to cut about an inch below the clip)......you can then get the clip off the removed bit of pipe and secure it on to the new cap

[@Nor4x4Way]

How to you get the turkey noise? (turbo surge sound?)

[@Sparkplugsteve]

The peron map woukd do it . It's enough boost to Turkey but not quite enough it open the dv. My current pumaspeed map doesn't do it and I think peron doesn't anymore.

[@joekeen3831]

Can you fit a boost gauge on a standard 2013 fiesta ecoboost?

[@MexicanPoro]

You can fit a boost gauge on anything making boost lol. Just gotta tap into it some where.

[@PeakPerformanceReviews]

I prefer mine with 👌 and ..... not gonna lie I’d be concerned that there is a little less boost without it ..... odd and weird .... can only guess it’s leaking by and I’d check the fit. Good luck bud good video

[@Sparkplugsteve]

Yeh I'm a bit concerned too. Iv not driven it since and as I had the family with me I only did the one pull. So it needs a thorough check over this weekend. Thanks for watching.

[@PeakPerformanceReviews]

Spark Plug Steve I always find a good place in mexico and do a number of pulls to see what it does before and after anything I ever do rather than looking at boost. That being said a gauge before and after should give a good indication. No probs fella!

Hi its all standard. Turbo noises are louder due to itg air filter. Check out my vid of fitting it and the noise. Its great.

Isn't flutter bad?

[@Sparkplugsteve]

This is running a factory standard recirc valve so all the flutter and whoosh is as ford made it. its only because of the filter that it can be heard. the standard airbox mutes it.

[@Roadwarrior92]

I alway's got told flutter wasn't good on turbos life span?

@@Roadwarrior92 Flutter is bad for the life span ONLY when there is more of it and if the air cannot be recirculated or vented to atmosphere properly.
