Your honestly the first car guy channel I can enjoy, I’m a technician full time but also like research and development along with car theory. If I had the chance to sit with you for 30 minutes to talk cars I would. I’m also going to be buying the cyllender 4 cooling upgrade. Price is well worth it for what your getting along with the right clamps to never worry about them
Saw some EGT charts that shows the change (decrease) in the delta of the exhaust temps between the cylinders. I cracked my #4 cylinder on my STI and this mod is going on my built block. Certainly worth a little peace of mind adding this mod. Thanks for the video and explaining it all!
It would be incredibly interesting to hear you explain in detail why closed deck blocks typically see higher coolent temps (and what manufacturers like IAG, outfront, etc.. have done to combat those temps)
Only when people use the wrong head gasket or have a closed deck design that blocks the exhaust side supply ports, do people suffer from higher coolant temps. I haven't had an issue with the new IAG stuff. People don't realize the exhaust side cooling jacket holes in the head are the supply to the head, the top half of the cylinder cooling jacket and the rest of the engine (turbo, heater core, TB, etc)
@@jack073 they're normal. I don't even know where the misconception came from that they're higher just because they're closed deck. It makes no sense at all.
Somewhere along the line, I heard that a closed deck run a bit hotter than open or semi-closed simply because all that extra material that sits around the head of the block. But its good to know the truth.
Hey Dom, I just got my cooling mod delivered. Thanks for such fast shipping times! Will post a video this week of how to install the hose from underneath the car. Your description that was sent with the mod is very thorough but i can see some people misunderstanding. Will keep youtube and nasioc informed about my findings and procedings. Thanks!
@@n54dame took me about an hour to install. simple hand tools. ive measured a 25* lower cylinder wall temp since installing the mod and definately less detonation in cyl 4. part was a perfect fit, used a little bit of pipe dope to prevent leakage. would buy it again, if i needed another one.
Oh and while this is not scientifically proven in any way or form, but perhaps is worth mentioning that my remote engine tuner in Germany said the 98ron is better in my country as he is able to be a little bit more aggressive in the tuning than he otherwise would. First of all I don’t think that is the case plus it is pretty much summer all year long here and the ambient tempt was always around 29 Deg C to 30 Deg C at evening when I collected the log data - and I am still on stock 2011 STI TMIC. Could it be due to the much better EGT delta across all four cylinders? Well I don’t know for sure but in theory it is possible I guess.
Really great video ! Appreciate showing some light onto the lt1 engines ! I feel the lt1 engines would have performed a lot better if hey had better flowing heads but they were still amazing for stock ! peak cfm on lt1 heads were 204. On the ls1 heads, it is 244. The reverse flow cooling system is awesome but I suppose that it was overcomplicated and not needed for street cars. So many cars could benefit from a reverse flow cooling modification ! I am not sure how possible it is to do it though....
Another great video! Love the in depth look at what is actually going on with different issues. PLEASE, keep doing this kind of thing! I'm interested in your fix for this issue.
Does this mod require a tune? Lol I’m kidding. I am running the factory “garbage” tune (93 recommended and I use 93). Will this mod help gain any kind of power? I wouldn’t think so but I just thought I would ask. Trying to prove to people that the EJ257 is reliable in stock tune form with proper cooling, oil changes (every 3,000), and 93 octane. I have been thinking about getting an AOS to help prevent fuel dilution even further. Put on 10,000 problem free miles now since my purchase. Thanks for the info! I’ll show my friends
Excellent video as always! Very enlightening to know why #4 fails more commonly, esp. due to detonation. Definitely looking forward to this new product! I'm guessing this could be installed before tune to allow a slightly more aggressive tune, or afterwards as added detonation protection on cylinder 4? I have seen many posts online from people claiming #4 failures were due to excessive heat and that using an ELH versus UELH would be very beneficial in lowering the heat buildup on that cylinder, especially on a higher power build. Any thoughts on this? (not sure if the answer warrants a video of it's own)
@getadomtune Do you have a podcast? ❤️ I owe you a fanboi debt of gratitude. I got the cooling mod with the stainless T. I saw where you buffed the casting scars off around the rim. Nice touch. I bought a Ford Explorer external oil cooler and I'm waiting on you videos about the oil cooling!!!! #getaDOMtune

Hey Dom, if you bring down the temp on cylinder 4's head, decreasing its knock tendency with this mod, doesnt that mean we would lose cylinder 4 as a "reliable" way of sensing knock? I mean cylinder 4 will no longer be as prone to knock as it was without this mod, doesn't that mean we could potentially miss knock events that are more likely to happen in cylinder 1, 2, and 3?
A completely valid concern and one of the reasons why I didn't make the mod flow the maximum amount of available coolant (I strategically sized the orifice in the fitting). I have some EGT and temp data that shows 4 is still hotter, but the delta is reduced dramatically. It's still the harshest cylinder, it's just not as harsh. cdn8.bigcommerce.com/s-gfm7bog6j4/images/stencil/1280x1280/products/112/388/CoolingModEGTs__30473.1533290766.png?c=2&imbypass=on
@@GetaDomTune another reason that "a few fittings and a hose" would be a bad choice of replacement parts. ;) Would you recommend this mod for people running OTS Cobb maps? I'm unsure if the Cobb maps has special timing and fuel adjustment for cylinder 4. I ask because from your video it sounds like the stock maps from Subaru actually has cylinder 4 timing and fuel adjustment to make that cylinder knock first.
@@GetaDomTune Its nice to hear your considered that, it was nagging around the back of my head for a while, I definitely think this is a good idea and will be purchasing two of these, one for each of my 2004 forester xt's, sometime next month as soon as I have the spare investment capitol. :-) As always thanks for the informative content... I think I've watched these video's 20 times each and am still glimpsing new nuggets of information with each pass.
Why does the coolant flow through the throttle body and heater core not return to the radiator but instead flows straight back to the water pump? Surely if those lines returned to the radiator there would be a huge decrease in coolant temps? Sorry if these questions sound stupid...
When the thermostat is closed, there needs to be a coolant flow path or you will damage the water pump. This flow path recirculates coolant through the engine without radiator influence so the engine can warm up. Returning it to the radiator when the thermostat is closed would be the same as not returning it to the radiator because it wouldn't flow.
Just got the cylinder 4 mod done on my 11 wrx. One of my buddies said that it’s actually bad because it messes with the sensor to adjust timing if you do get knock, is that correct?
The FA has an improved flow path, FYI. I just finished a complete analysis of the FA cooling system. They did right on the FA all the things they did wrong on the EJ.
Ah, that's good to know! Where did you end up finding the info for the FA20F? I looked in the service manual I have and couldn't seem to find the flow diagrams, there is a chance I'm blind or maybe I'm missing some sections. Congrats on getting your EJ solution completed and released!
Hey Dom, I god the cylinder 4 cooling mod but my room mate got me the Torque Solutions one for Christmas. Would you be able to do a comparison of these 2 or if it’s as good as yours or close to? It looks VERY similar -John
@@GetaDomTune aw man I was planning to use it for my NA EJ22 for my rally car. Maybe I should test it out and see if it does fit. If not I can always put it on my EJ25. Thanks Dom for making a awesome product 😍🤙🏼🤙🏼🤙🏼🤙🏼🤙🏼
I can't hear anything your are saying because all I can do is stare at your collar being tucked in on one side lol. Seriously though I love the concept. Let me know when its time to test. I'm the best at putting heat into engines ;)
Bruh, you and I went round and round on Facebook over cylinder 4 having less fuel. You ended up bitching out and blocking me. You just admitted what I was saying from the start. Cool cylinder 4 with the proper A/F you'll get better cooling. Your mod may add additional cooling, just a band aid bro. Buwhahahaha /slow golf clap
still stupid huh? Even your reply here shows you have no clue what you're talking about. This isn't fixing AFR, it's fixing burn speed and heat retention.
