Thing is, Subarus are so specific that if you don’t know what you’re talking about you’re gonna get called out on it. Like this guy.
40 horse lol he must be smoking
The unequal length headers give it the distinctive noise not the orientation of the cylinders
But they limit horsepower. If u instal equal length u get easily 20hp more ,but lose specific rumble.
@@malboro555 that's interesting I didn't know that.
Had to turn off when he said that. Hate when people chat shit on big name shows
@@malboro555 20hp is a lot bud. Maybe if he also removed the mufflers and tuned it properly.
Headers only have me 12hp at the wheels without a tune and mine is a 5L Supercharged V8. Muffler Delete would pose more of a restriction on this car??
TBH I didn't watch the whole video because the guys an idiot and there's so many erroraneous statements in it
@@darieldesvignes942 Check Killer B Motorsport , they make a good stuff for Subaru.
As soon as he said ''2001 model'' i just closed the tab...
dead ass
Why tho
@@canneddinners6059 cuz thats not an 01. its a 04-05, two redesigns after the 01. credibility is out the window if you cant even correctly tell people what care it is
If you closed it straight away, how’d you write this comment 🧐
@@hawkwardwrx In japan and europe the blobeye was sold from 01-03
"Let's move the intercooler out of the hot engine bay"
(proceeds to install cone filter in the bay) 😆😆
Oh dear... not sure what’s worse.. STI Badges on a WRX... or that open cone filter sucking in hot air 🤣
FMIC increases lag too
langra man until you map it
the hot air intake hurt me inside
@@Birmingham_racing map can't fix loss of pressure lol
His beard lol
My trust of him died when he couldn't even got the year of the car right, let alone his explanation of why the Subaru makes a distinctive noise.
Jimmy, the emissivity of black paint > silver paint. That's why factory heat exchangers a.k.a intercoolers are made from aluminum and left in their natural colours. The lighter colour body absorbs less heat than darker colours.
I like how the car conveniently has the crash bar removed before the bumper. Minor detail to consider that he left out.
Piping is so long .... the Turbo lag will be longer than the pipes. And 40 degrees cooler gives you 40hp more ? .. you will be happy if you get 4hp
Nah man, this is probs the only true fact of the video. I didn't watch the whole thing because the guy is a stupid uneducated idiot. However intake temps do make a massive difference to forced induction cars. (If they have been dyno tuned properly)
For your info, look up "Forced Induction Interchillers" I've got one on my car and it makes 70hp difference with it on and off. Mine is a supercharged 5L V8 though.
blocking the radiator is good too
Absolutely can make more than 4hp - with a tune to take advantage of three intercooler you could easily be looking at 30 to 40. The lag increase isn't really that noticeable to he honest but yeah, there are absolutely better options than going straight to a front mount.
@@jazzmangocats lag can be fixed by rotating intake - way shorter tubes. And yes, definitely a tune to accommodate everything. Big no no on that filter. Just drop a K&N in the stock airbox and you're better off. Safe travels, everyone!
Great way to blow up your engine without getting a tune.
Ive fitted 100s off fmic and never had an engine blow without a map infact it reduces boost pressure through larger diameter pipes and bigger cooler
The ecu will self adjust and will remain fully safe. Yes a map tweak would help figures, but there's no danger to not.
I'm talking about that hot air filter. Subaru's need a tune when a filter is installed.
How can this be a 2001 Impreza when the Blobeye was introduced in 2004????
According to the DVLA this is an 03 car. I also had an 03 Blobeye, FX03 XVU
This is definitely not an 01 anywhere in the world. 01 would be a bugeye, except for in the US where it'd still be the GC body style, and not turbocharged.
Pretty sure its a private plate, which can be older than the age of the car.
Lose the mud flaps I hate mudflaps on evos and scoobies
IMO it looks toilet
hell presidenti he said it's an 01 impreza
Should be titled how to blow up a Subaru. Do not worry about tuning enjoy your extra power for a few days then bang! Awesome video lol
Americans did it worst
Even though it's 2022, the time of technology, practicality and marketers, and this car is still popular and it's cool in all its sports parameters. Nice car. Thank you.
Wonderful in depth video on how to quickly blow your subaru engine without any tuning! Fifth Gear is getting toooo smart. rocket scientists 👩🔬
Why, oh why is it called fifth gear when the picture is of a four speed transmission?
Bettter question y do u care
The picture is clearly a five gear speed transmission with no reverse on it
who else is loling?
I watched this two days ago and I've only just recovered
So much nonsense in this!
3 grand, lucky to get a really clean wrx turbo for under 7k. Best thing you can do with them is keep them 100% original like mine.Keep it a good few years and you will get your money back all day long
That's why I always look forward to the winter. Those gains mate....
Wish there was some actually dyno numbers to prove the difference.
Another "CUTTING EDGE!" 2005-era tutorial from Fifth Gear! ;) Cheers!
This wrx will not self adjust for the cooler charge temperature without a map & cone filter is going to loose you power. To make more power from blob wrx, ditch the up-pipe cat, replace the whole exhaust with 3" turbo back sportcat/decat, decent panel filter.. dyno remap with someone reputable & run the car on proper fuel aka shell vpower. This should see 280/290bhp. If this is not enough, you need the sti turbo or something of the shelf & probs then look at intercooler but at this point your pushing your luck with the 5 speed.
Love the channel!
#FifthGear Do you have any proof that the car made more power after those modifications?
those do not add any more power, not without a tune at least
I bet it lost power without a tune, in fact I garuntee it, plus the stock intercooler is good for much more power then stock, and going to a cone filter isn't going to do much, now it's just sucking in hot air, total clowns
@@dallasmellsop5488 yep if they had done a larger top mount intercooler it would have seen gains, and if they had just purchased a true CAI they would have seen some more gains. I purchased an aem intake and I believe the crank hp gain was +40 with a tune.
I ❤ my '98 Terzo Impreza. A classic.
If you have a wrexi, embrace its original bodykit and not add sti parts coz in the end, its still a wrexi
Or WRX
Ill ask this here cause it kinda fits my question.
I preferably want to buy a 4WD as a first car but I've really no clue, if a WRX or STI would go well fresh out the gate. The non turbos seem logical, although I want to be like a project aka look the part but until the insurance eases, then go for performance. Practically, I think buy that point it'll be cheaper or less effort just to buy WRX at that point.
So after you remove the blow off valve from the car without replace it (because in the wrx it is fitted on the intercooler...,-) how many miles you need to blow your turbocharger????
So cringe, i feel sorry for the guy in a way dealing with this embarrassment, but im alot more upset about what they’ve just done to that Subaru lol
Ringer alert. Didn't make blob eye in 2001 that's a bugeye with a front end change even the radiator is wrong for a 2001 model upto 03 didn't have the cap on the radiator only had the one on header tank near turbo. Don't ever do this work without remapping you won't get no gain without correct afr if anything you'll make it slower from bad fueling and increased lag. Air filter pod = lean, front mount = lean and then people wonder why subaru are considered fragile.
Keep it standard and the price will be skyhigh in 10 years
My old impreza had 158k miles when I sold it never broke down once. Never had the engine messed with or nothing like that.Keep them 100% original is the secret. You see so many that have had engine rebuild ect, leave them alone and they will run for ever
They had engine rebuilds because they didn’t last forever lol
In theory, the cooler air will outweigh the possible turbo lag caused by more/longer air travel. Cooler air will also allow higher boost, cooler air contains more oxygen, allowing the engine to burn more fuel creating more power.
But...
Without decent remapping the ECU's won't allow boost exceeding the set parameters in the programming, and definitely will not allow more fuel into the engine.
With a proper remap this might work fine, but like this? Nope.
Do I need a tune on this car if I get a CAi?
Say it with me. "Heat shield and a tune." That argument about the hot engine bay for the intercooler is way more important for the intake. Heat soak is real and a small shield can work wonders. An enclosure is better. Also, no tune is a terrible idea.
How to increase turbo lag and install hot ar intake no reprogram needed.
yeah agreed.. there's a reason the IC on the Ej is mounted there, but people insist on listening to these muppets rather than the people who designed and built it
@@dagnut tuners and garages just make money from the bs. plus the fmic has covered half the radiator up now lol
Black dissipates heat, thats why houses in sunny places are painted black 🤣
This is the exact reason people manage to blow their engines, making nonsense "mods" without even a tune... Poor Subie, hurts me inside watching this!
That intake so better have been tuned for... Rip consistent A/F ratios 😂
So we just gonna ignore the fact that Captain Price started modifying cars???
😂😂👌
How to ruin a car
This is fine, but going above 800hp will kill the car straight up
@@hybridAbsol no it's not an increase in power, this guy means that the mods they did were shit, cos they were, an intercooler with no tune won't add power, pair that with a filter that now sucks in lost air, it drives worse and probaly LOST power.
Plus, the stock intercooler is good for much more power, this really was an embarrassing video, espically when it blows up because it's a subaru with no tune
Black doesn't dissipate heat!!!
Oh yeah 40 bhp extra totally
This comment section has absolutely ripped this guy lmao
The EJ engines need a new ecu map when the airfilter is changed to an open sportfilter. The same thing if the downpipe, headers, turbo or downpipe is changed.
it needed nothing doing to it
@@langraman8756 you should make a new maping because when you are changing the airfilter and and the filterbox the map sensor is not working correct on low rpm .
a catback is fine without a map, had one on my stock impreza for probably over 15 years
Can you still by an impreza STi for under 4k?
No haha I wish. Can't even get a nice WRX for that
@@tomcliffe4572 any idea what model from 97 to 2005 is the LEAST popular STi and WRX? the more likely to be a lower price from a B grade one
Missed a old Subaru trick here. If you add the rally decals it gives you 10 more hp
arent you meant to get a remap after any engine alterations?
This video is full of old wives tales. Black doesn't work like you think it does with heat, and the burble sound is more about the uneven exhaust header lengths. The bigger intercooler is likely to help, but 40hp is a massive wild claim without tuning and bigger turbo. Without other mods an upgraded top cooler would probably be a better buy
No remap??
6:35 so basiclly the cone filter he installed in the engine bay is negating the fmic install then? well done sir
Only the uk spec Impreza’s had unequal headers and the Japanese spec had equal length headers and the Japanese spec had better turbochargers and the intercooler was Water cooled
Can you use water spray on the intercooler when the intercooler are moved to the front?
Only if you moved the jets aswell . The sti comes with a IC water jet as standard
Ok, thanks for the reply😄
Hot air intake?
@6m30s: "...cooling the air ENTERING the turbo..." Intercoolers are supposed to be installed AFTER the turbo, so they make no difference to the air entering the turbo. The only thing you've done to the air entering the turbo is to fit the conical air filter, a move that often results in slightly higher air temperatures into the turbo as the OEM solution to air filtering often includes cold air inlets.
Unfortunately you don't know as much as you think you do. turbocharger can be intake side or (as per most vehicles) exhaust side of the engine. It is often on the exhaust manifold.
@@tracktimevideos5164 Your attempted rebuttal makes little sense. My comment included the quoted phrase about the function of the intercooler where it was incorrectly stated that the intercooler is for, "...cooling the air ENTERING the turbo...". This is in reference to a system point of view, i.e. where the air flows. It has absolutely nothing to do with the physical mounting point of the turbos themselves. Compressing air in the turbo increases the temperature, followed by an intercooler for the air EXITING the turbo. Nobody installs an intercooler before the turbo as that would make no sense. Can you now see that your comment is completely off the mark? Please focus your attention on the quoted phrase that can be found in the video at the time stamp that I also referenced. I'm pointing to an error where the narrator misspoke. Your rebuttal to my comment is incorrect. "Unfortunately you don't know as much about the English language as you think you do...", LOL.
@@tracktimevideos5164 Of course it's on the exhaust manifold!
The exhaust gasses spools up the turbo, which in turn forces compressed air into the engine.
And compressed air gets hot! Hence the intercooler, cooling the compressed and hot air before it enters the intake manifold.
@@tracktimevideos5164 That is so wrong lol wtf
I didn't know that about colour black dissipating heat. Does anyone have more detailed explanation?
It does not 😂 Engineering explained has made a video on it👌🏼🙈
no need to explain half the radiator covered up too
Damn where can I get an “Impretza”? Never heard of one
Thats the right way of saying it, like pizza
I wish wrx's were 3000$ you'll be lucky to find one 9k, let alone the sti you'll be looking around 18k if you're lucky. Also love how he says the wrong year
saw a video like this before, somebody wrote this in comments: subaru: engine of the year 2016 This guy: I am gonna improve it.
The color black dose not dissipate heat better. The type of metal would actually have to do with that part and actually black is a heat soak put out some thing yellow in the sun next to some thing black that is the same material and the black item will be hotter when measuring the surface heat.
Correct, but also wrong.
Black coating don't dissipate the heat as such. It absorbs the heat, in theory it absorbs heat from the intercooler core.
But in reality? Nah.
Alternate Title: How to Blow a Head Gasket
I'll be doing a video series on how to do these modifications properly without risking your engine. SPOILER: get a tune.
How the hell does a FMIC give you 40bhp...... absolute nonsense 😂
To start with...... any change to the intercooler setup would require remapping. Just chucking a FMIC on is not gonna get you that kind of power..... all you will get is lots of lag 🙈
The stock FMIC on a WRX isn't great but still OK until you are pushing 300+ bhp. Even at that, upgrade to the STI top mount intercooler, underboonet plastics and bonnet scoop. A much better upgrade unless you are planning 400+ bhp.
And don't even get me started on that cone filter 😂
yeah we all know how black metal never gets hot...
All that work and then skipping that vital step at the end. What a waste.
The FMIC has covered up half the radiator lmao Some idiots mainstream media puts out. Low standards. Hot air intake filter. lag introduced with FMIC lol
sad we wont have this engine anymore
My Evo9 will eat that Scooby for Breakfast!😎😎
Your evo 9 couldn’t beat a 1 litre automatic polo from 1997 though could it
Any Subie bro knows that's definitely not an 2001. The blob eye is 04-05 gen
From 03 matey
private plate me thinks
that’s not a 2001 model that’s a 2003 04 model bro
What a load of bullshit, that 40HP increase logic LOL
The dumb wave species legs are a tuning fork @ 7 oclock to cover the blob on the templars challet
Sorry guys shit happens
WTF? This is why I keep my brain running on stock settings…..modified brains can blow your engines!
Love the beard nobody ever said
Since when did Captain Price put performance parts on subies
Put a H.K.S panel filter with aftermarket silicone pipes ... would make more power then that pod filter 😂😂 lol soo 90s era hahahah
Do you need a beard like his to start off with? 🤔
This episode, to me, looks as if it was filmed, in and around Callow End in Worcestershire, and the road the car is tested on the new intercooler is installed is Jennett Tree Lane. Anyone able to confirm for me? Also looks like the Malvern Hills in the background (specifically The North Hill).
Bet that pulls like fuck,,,,,,timing that is
Wouldn't you have to re-tune the ECU?
Yes you would, this guys a clod.
I understand why a FMIC but i rather have a funtional hoodscoop than replace an entire piece to look like a regular impreza
40 HP increase.... Nope, probably lose power. Massive turbo lag increase too.
I keep mine stock.
This isn’t a 2001 model...the blob eyes were released in 2003...
It's no wonder people blow their car's if this is the kind of example they follow, so much misinformation and serious lack of knowledge, the presenter might have the gift of talking the talk but he stumbles when trying to do the walk. Doing it like this loses power and makes for dangerous lean running situations when just a straight forward remap will net more gains than slapping tut on it! Without changing the turbo/injectors/fuel pump and remap there are absolutely no gains from doing this just a butt load of losses/risk.
A dyno before and after would prove some of the claims. I bet it will not be a 40HP gain
No remap is asking for trouble. You cannot add stuff to these with out getting it mapped. Det time
He forgot the Flux Capacitor.
We have done accurate tests to determine the engine is doing 40+ hp more
the tests: trust me bro
Don’t think 40hp. Pod filters are proven to decrease hp. Sock air box is rated to 300hp all you doing is letting the motor breath hot air. As for front mount I wouldn’t be boosting until you have a tune. Won’t see noticeable gains until then.
Complete BS. I bet this made almost no difference to the BHP. These ‘cold’ air intakes usually decrease BHP in most dyno tests that I’ve seen. On these cars, there’s an air scoop just above the grill so I seriously doubt whether this cone filter helps.
Regarding the front mounted IC, a useful mod but needs to be combined with a remap, up rated fuel pump and injectors. And preferably a revised exhaust system.
Nah dude 40bhp I swear.
Has 500bhp now
With a heat shield it helps
No it doesn't. You don't need an uprated fuel system for an intercooler lol
And yes a cone filter may slightly reduce bhp on an unmodified engine in a rolling road due to heat soak, but that doesn't apply to a car moving through the air.
sirjakethebrit
What I’m saying is that a FMI on its own will produce little extra power in this car. Real gains are predominantly made from increased boost which should be done correctly with a remap. Most tuners would also recommend an up rated fuel pump and bigger injectors for modest boost increases especially on a regular WRX (which this seems to be).
I'm no.mechanic but was in the Subaru scene for many years and had 4. This is the biggest amount of bullshit I've ever seen 🙄
40 hp for an intercooler upgrade nice i think i will put 2 of them on .LOL. take that cone filter off they are rubbish
Last time I was this early I was still in my mums wound
0:54 its not a 2001 model vehicle
Nice Impretza or whatever he said lol
Front mount on a impreza actually sucks on stock turbo lowers cfm too much
Wow
Uhhhh the stock intercooler is good for 400hp 🤦♀️
so Tiff got traded for this clown???he is actually funnier than an actual clown goes vroom vroom...my iq level really went down after watching this🤣🤣🤣🤣🤣
2001 model? Anyone seen my continuum transfunctioner?
I mean surely you need a tune before any of that will make a difference past a couple of hp
You just ruined that car.
+40hp my ass
This guy worked on that Goblin works garage... 😂 Their ideas are frankly dangerously stupid at times. His are just reigned in dumb.
