For those that skipped through it, 0.2 bar of boost was added to achieve the actual dyno gains (10-12 whp gained per psi). The challenge with the intercooler is determining what you need in a dynamic situation to maintain stable IAT values at your selected boost level. I would be VERY interested to see how a Spec C top-mount factory I/C with Auto water spray compares to a front mount in terms of being able to push the boost.
👍 The ic auto spray doesn't tend to make much difference on the dyno from when I have tested in the past (pre TH-cam days) I will, however, see whether a suitable car arrives to making a video of the test going forward. Size and location will work against a spec c tmic compared to a fmic though. Thanks for watching and the comment 🙏
@@stock.cars.2ned more boost doesn't always mean more power hence why it was capped at 1.4 bar on the tmic map. Running more boost on the tmic meant that much less ignition could be run and even with more airflow the power made was less... Sorry for not going through a million different scenarios of the tuning, but this is someone's car, not a shop owned test mule where I can do endless takes for the video. The comparison was optimised and safe map for tmic vs optimised and safe map for fmic and as such valid.
@@stock.cars.2ned I think it's a fine test, and glad the boost increase was shown... but selecting an optimal intercooler for an application is a real pain in the ass and takes a lot more logging time than a day in the dyno can provide.
@@racedynamix I understood the take-away - a more efficient intercooler can allow to you operate your compressor further outside of it's efficiency island and squeak a bit more power out of the setup. Pushing the limits in this area requires fuel and spark tuning, and then subsequent logging of IATs to validate stable temperatures.

If you were running a Process west Top mount you'll still make that power figure and keep the spool, the stock sti top mount it's limited to what psi it can hold and still remain thermostatically efficient
They cost a fortune, also heatsoak whilst sat in traffic is still an issue, and the other issue with air going over the scoop over 100mph is still there. Top mount is fine for a road car really.
They are good but still nowhere near as good as a fmic. The wrong location so suffer heat soak and issues with airflow at speed missing the scoop altogether 👍
I wanted to love my TMIC... I monitored temperature with an IAT sensor in the TMIC and the TMIC would easily get ~20F hotter at wide open throttle; any additional throttle outside of casual cruising would heat up the TMIC. I installed an FMIC, transferred over the same IAT sensor, and saw the exact opposite effect, as you mentioned, it gets cooler the faster you go. It also cools off quickly after heat soaking while parked or in traffic.
@@stock.cars.2ned If new hardware (or better fuel) pushes out the safe limit of boost and/or ignition timing: (a) changing neither of those would show a small difference if even measurable; (b) changing the tune parameters to make use of the better hardware will show the meaningful difference.

Yeh, that was a good day nice. Its nice meeting accademy members and seeing their cars make power. That noise Never gets old ❤ Good work on video Duncan
Thank you for making such an informative video. I have a FMIC on my classic but was seriously contemplating going for a top mount from an sti new age as aesthetically they look great. However, after watching this video and your excellent wording from wisdom, I have permanently removed the idea from my head. Cheeeeers 😊
IMHO the best TMIC for Scoobarus are made by Wagner Tuning. They are tube and fin tech and they are ginormous. I made a good bunch of horsies by changing from the STI one (and also upgrading the hood scoop and a custom undertray to suit).
Would have been great to show 1.4 bar vs 1.4 bar, but I’d be happy to push 1.6 on both setups with proper iat compensations set up. I’ve tested all 3 setups tmic,fmic, and custom water to air and wta wins all with ease.
Noted. The car will be back again at some point and we will try and do some more filming 👍 The objective was to see the difference in power though from an optimised map on a tmic to an optimised map on fmic. Regardless of boost the fmic enables more power to be made. Running the tmic at that boost on that car would not make more power than it did at 1.4 hence why it was mapped at 1.4. The better efficiency of the fmic at removing heat allows more boost to be used.
I'd just like to add, (my car by the way ) My previous mapper did add more boost at first with the top mount but it wasn't making more power and was creating heat. The car was happy where it got mapped. Plus it was a warm day outside and was mapped on the road. This example is of my setup. All setups will give different results. My aim from this video was just to show the outright difference from a turbo that's rated in the low 400s where boost levels will be high and so will the heat. Could of easily of got a big 500bhp turbo and run lower boost to achieve 450bhp, but I wanted a turbo that gives great responce and boost that comes in nice and early like oem. You can go crazy onhow indepth the tests are, but this kind of test with this setup just shows very quickly what a front mount is capable of. And shows the limitations of the top mount at this level.
Great video. What are your thoughts on companies selling their fmic kits as install ready requiring no remapping? Did you change fueling or timing at all?
I think that is wrong... Fitting a fmic requires fitting an induction kit and that changes fueling. On this car the induction kit was there for both tmic and fmic so I didn't change fueling at all. It took more ignition timing and because the air was cooled better it allowed me to run more boost. 👍
There is no issue with hawk scoop and air flow till 480hp,always You can put bigger scoop.You gain more air as sti top mount is to small to take more. Process West top mount with scoop undertray is best to go with that power level. I will more worry about heat soak trough air cone filter ,should be in a sealed box with air snorkel attached and about brakes going above 100mph on track.For track just remove engine undertray .Than You block radiator with front mount intercooler giving it less air to cool it down. Engine oil cooler could help to plus meth map.
I am sorry but that isn't going to happen unless they all give me their version and it would need to be done on the same day to make it a truly valid comparison. Sorry
It's never a bad thing but subarus have never been any higher then 340bhp from the factory (apart from the cosworth 400 version ) Most are like 220 to 300 on average from the factory. Sti top mount performs really well at that power level. And the bonnet scoop is so iconic now that I couldn't imagine a subaru without one
It would be nice to have a simple comparison with what ~numbers to expect from 500 HP British to 500 HP US dynojet to 500 US mustang give or take. 👍🏽👍🏽
thanks for the response. I am aiming for 400bhp . Was going to upgrade the turbo from stock vf34 and upgrade air intake bigger injectors and a good remap. But was unsure if 400 would be safe on the standard engine. Also keeping the standard clutch on the car as well. Has the Sti top mount intercooler
Hi. Those mods won't make 400 tbh, a more realistic target for those mods is 340-350. At that power level the std engine should be fine if tuned det free and with good maintenance.
@@racedynamix ok. So a hybrid turbo upgrade bigger injectors front mount intercooler upgraded induction kit and a down pipe straight through 3inch and a updated fuel pump and a custom won’t make 400 from 280bhp what would I need to add to the list to make the 400
@@silenthill87 ah a hybrid 400 bhp capable turbo might help you get there with fmic and injectors 550cc or slightly larger... But you are definitely into engine death territory.

I prefer TMIC because of OEM placement. Car sucks during the summer. Bare killer b headers, turbo blanket for the 20g turbo, Koyo radiator and I have watch temps lol
I've only seen them on videos. Only difference I see is the quality and fitment tend to be better. I knew someone running a timeattack car with 700 plus bhp with a cheap ebay core and his temps was fine. Biggest fitment issue is having to destroy your front bumper on the inside, but I think that's the case regardless. I think for the money, this particular kit doesn't fit bad at all.
The fitment of the more expensive kits is much better, the pipework quality is much better too. Some of the cheap kits you wonder whether the designers have even ever seen a subaru 🤣
Great video :) I've got a question re 2.5's. Despite the STI having a redline starting at 7000rpm the 2.5 ALWAYS seems to start bleeding power at 6000-6200rpm. Even with the AVCS they seem to struggle, but why? is it a breathing issue (head ports/valves etc) or a displacement/stroke issue? Part of the reason I went from 2.5 to 2.1 on the Type R was to gain an extra 1000rpm of rev range as you could feel the power leaving the chat after 6k rpm. Might be worth doing a video on 2.0 vs 2.1 vs 2.3 vs 2.5, as I know the Gobstoppers are all 2.0 but people think you need a 2.3 for monster power.
@@benc911 other than spool up it doesnt explain what I asked. I've built/run/modified Subarus for years, run 2.0, 2.1 and 2.5 engines etc and Duncan has probably tuned 200+ cars for us.
Great vid. The interesting thing here is the spool hasn't changed on the graph is that maybe to do with altitude? I am in an area where we are at 5000ft above see level we do see the difference in response from a front mount to top mount almost 1000-1500rpm specially on the 2.0 but the end power figure does vary. The 2.5s however really do perform better with front mounts.
Indeed... Response and boost threshold are different, there will be a slight delay in refilling all the pipework from a fmic but once going it will outperform a tmic easily 👍 even at altitude 😎
I've heard that FMIC on subarus with stock location radiators reduce the cooling effectiveness of the radiator because the FMIC is blocking a portion of the radiator. Thoughts?
If he had a smaller front number plate it would easily have made another 200bhp I reckon lol, seriously though for a cheap cooler that is great gains and the pipes fitted well by the looks of it which is normally the issue with cheap intercooler kits
I dont really like to cut my prodrive bumper for a fmic Also those aftermarket ic are way thikker material that means when heat soak they will take longer to cool down I was also wondering what the effect of the ic spray on the ic is and how much does the temp drop and what the result is on the power
Heat soak isn't an issue at the front and airflow works to cool them much quicker than a tmic. The IC spray does almost nothing, I have tested in the past but will do a video at some point on that actual effect on numbers 👍
I’ve got a fmic in the boot lol still to be fitted to my sf5 fozzy s . Yesterday some kind gentleman smashed into my beloved fozzy parked at the side of the rd back to welding thought I was done . New rear quarter panel bumper tail light trailing arm bracket the joys of motoring…… my fmic is all silicone hoses no metal does this affect it?
Hi have a question. Is the 2005 2.5 sti engine any good? I hear a lot of Bad reports about it. I want to run 360bhp. Will the heads and rings be ok at that level of power?
Hi.. Great question. The 2.5 is inherently weaker in design but should be OK to that power level if mapped to be det free. The Ej207 would be much more capable of handling that power and significantly more tbh. The ringlands and headgaskets are a weakness on the 2.5 but it makes for a great road engine because of torque. hth
No extra power bra.. the front mount actually creates a heat trap that soaks everything with heat and is pointless in every way, unless…. You have your radiator in the trunk like the rally cars that use front mounts. A well ducted and proper sized top mount intercooler will yield quicker throttle response and recover from heat soak quicker, as well as not blocking the radiator from doing its job cooling., top mount for the win on your average daily driven rally car. Unless you move the rad to the back. Then front mount obviously would be better.
I think they would be better but still suffer from heat soak and inefficiency due to location and direct airflow, albeit the newer scoop is a better design. Fmic still wins outright imo
@@stock.cars.2ned it might also be a sales pitch, but nothing was incorrect. FMIC can be bigger, and doesn't heat soak. The dyno numbers from many tuners show the positive results of an FMIC over TMIC, and I hate to admit it because I love the top mount- , but the data backs it up
Hi there was thinking about a front mount myself .but will it need a stage 2 remap to feel the benefits thanks . Currently running 320bhp on stage 1 tmic
I don't really do stage 1 or stage 2 maps.. Just custom maps for whatever is on the car. There will be a power gain on your from fitting and mapping a fmic though but at that sort of level a tmic is doing OK 👍
I have customers running 496bhp on the std engine... But they are aware that they are on borrowed time.. It will break at that level. There isn't a hard fast limit on power though.. What are you aiming for?

it is mate, buy the gravity version as its the same but youll save £100. Just remember its a cheap kit, fitment is fine, seen worse and copes with decent power.
@@thomaswahahauw560 Yeah it would need a tune as you would be replacing the std induction set up with an induction kit of some shape. That will alter Afr .. mostly leaning it out.. and could make it dangerous or run badly 👍
@racedynamix how are you getting away with fuel delivery only using 850cc injectors..? Here in Australia I don't know of anyone using anything under 1050cc injectors. 🤔
@@NovoGold the max power that a set of injectors can flow for is approx 70% of the cc assuming good fuel and other supporting mods. 1050 cc injectors are good for close to 700 bhp

@@stock.cars.2ned it might also be a sales pitch, but nothing was incorrect. FMIC can be bigger, and doesn't heat soak. The dyno numbers from many tuners show the positive results of an FMIC over TMIC, and I hate to admit it because I love the top mount- , but the data backs it up
Hi there was thinking about a front mount myself .but will it need a stage 2 remap to feel the benefits thanks . Currently running 320bhp on stage 1 tmic
I don't really do stage 1 or stage 2 maps.. Just custom maps for whatever is on the car. There will be a power gain on your from fitting and mapping a fmic though but at that sort of level a tmic is doing OK 👍
Where did the first one go 😂
Lol.. There was a couple of blank bits in it.. So I had to delete. I couldn't live with it having obvious defects over and above my own deficiencies 🤣
I wonder if there would be as much a gain with a smaller oem size turbo like the td04 or vf35?
The gains won't be as much obviously but it could be worth it if car used on track etc.
Awesome video
Thank you very much 🙏
I’ve a question. In a 2004 blob eye 2.0L wrx sti.. what is the maximum bhp the engine can take without having to forge the engine etc
I have customers running 496bhp on the std engine... But they are aware that they are on borrowed time.. It will break at that level.
There isn't a hard fast limit on power though.. What are you aiming for?
@@racedynamix thanks for the response. I am aiming for 400bhp . Was going to upgrade the turbo from stock vf34 and upgrade air intake bigger injectors and a good remap. But was unsure if 400 would be safe on the standard engine. Also keeping the standard clutch on the car as well. Has the Sti top mount intercooler
Hi duncan is this the japspeed fmic? I was thinking of buying one for my 04 sti, do you rate them?
it is mate, buy the gravity version as its the same but youll save £100. Just remember its a cheap kit, fitment is fine, seen worse and copes with decent power.
A fmic is a good option for you 👍
If i build a fmic on my subi,2013 sti full stock, do i need to tune my car ? Would I still benefit the iat as well ?
@@thomaswahahauw560 Yeah it would need a tune as you would be replacing the std induction set up with an induction kit of some shape. That will alter Afr .. mostly leaning it out.. and could make it dangerous or run badly 👍
Shouldnt the top mount be able to hold the same amount of boost? Or did you just up the boost with the fmic?
The top mount can't rid of the heat quick enough so wouldn't take more boost before having to reduce ignition timing and actually make less power.
@@racedynamix Ahh i see
@@racedynamix Would this apply with a speed density tune?
Is it worth it to get a fmic with a stock vf39 turbo? I live in an area that averages 105-110F in the summer.
It certainly helps keep air temps going into the engine low and that is extra safety at the very least. 😎
Good watch 👌🏻
Thanks Rob 🙏🙏
How about heat sosk in hot weather. Arizona , florida
Definitely beneficial to have a fmic there 👍
@@stock.cars.2ned why so aggressive?
Good job
🙏
What front mount kit did he use ?
Gravity/japspeed
I think it was a Gravity kit 👍
850cc injectors, that's not possible
@@NovoGold what's not possible ?
@racedynamix how are you getting away with fuel delivery only using 850cc injectors..? Here in Australia I don't know of anyone using anything under 1050cc injectors. 🤔
The standard injectors can cope with upto 400bhp so why couldn't 850s cope with 50bhp more ?@NovoGold
@@NovoGold the max power that a set of injectors can flow for is approx 70% of the cc assuming good fuel and other supporting mods.
1050 cc injectors are good for close to 700 bhp
@racedynamix all good, I just wasn't aware of what stock injectors would cope with. Thanks for the info, much appreciated 👍
