Thoughts/Reviews about 'GetaDomTune' Cylinder 4 Chamber Cooling System?

I am seriously considering installing this kit in order to 'save' #4 from exploding on my next engine. There are some discussions/thoughts on other forums about it. Yet, I am curious to hear from any fellow forum members who have installed it.

 

Have you noticed less knocking over time?

Did you try to add more timing?

 

 

Although all 4 cylinders have similar EGT temp after installing this kit, the EGT temperatures for cyl 1-3 are now slightly raised. This may also mean that the turbo may run slightly hotter too?

 

 

 

Thoughts?

Sub'd, curious about this as well.

No thoughts but have had it pulled up on my phone for a bit.

 

Couldn't find a good consensus on nasioc about it other than "it probably won't hurt"

 

Interested if others know as well.

Dom is definitely a reputable subaru guru. The shop that did my sti power steering rack install also fabbed up one. I almost bought one during the cyber monday deal along with other parts. I backed out and figured if my car has been fine these past 11 years why change it now.

 

This does all make sense and will probably do this mod when I get my block built/get a new shortblock. The thing i feared was the other cylinders getting a bit warmer and with 138k I'll just let it ride. Even temps across the board seems better and #4 is a nice improvement. I think I even saw his YouTube video a handful of times.

 

I'll probably still pick one up and install one for the heck of it. Would like to see more data and installs/reviews. Boy this legacy is a never ending project hahahaha.

I will pull the trigger and buy it and have it installed with my motor in April. I will report back . Might as well since I am having the new short block put in. Edited February 13, 2020 by NORULZleggy

That is exactly my worry. I don't recall him discussing this.

I started dismantling everything last night. Hopefully, this evening the engine is on a stand

yeah I figured why not, I have my date set, and all my parts, can't hurt. Fresh OEM VF52, OEM STI short block, and great tuner for break in tune and great shop. Can't believe I am building this car to drive it slow lol.

 

I like to stretch the legs, but I have got flipped off by people for taking my time and driving like a normal person. hahaah

I've had a similar kit in my possession for a few months now, but have yet to install it. I basically bought the OEM fitting used on the twin turbo setups. I've been putting it off even though I have the OEM coolant and conditioner in my possession already. I have yet to ask Bill (Tuner) if this modification will require any adjustments to the tune, I don't see why it would need a tweak but I'll ask none the less. Edited February 13, 2020 by Gabo

I'd be surprised if it needed anything but based on what I've read if this would lower and even egt couldn't you theoretically get more out of the engine.

 

The whole point is to lower temps in cyl 4 which is the one most prone to pre detonate. I think I understand that correctly?

Yes. You don't need a retune, but you may be able to squeeze more power out by changing the timing a bit. But I would not expect the change to be that drastic.

We need a thorough experiment by covertrussian to test this out...

good suggestion. We need to bug him to do this.

Food for thought: My engine (203k miles) started failing on cylinder 4, low compression and poor leakdown results. Not catastrophic and could be completely random, but apparently I felt the need to contribute today.

203K is pretty good. My other car has 165K and still running strong.

That is precisely the point of the modification. Bill stopped at 500whp because I wanted him to. He was sure there was more left. I was :spin: I don't have any equipment to measure temps so I can't offer to do any testing. I'm contempt with Dom's research and results though.

I have looked at this a few times.

 

My only real concern would be introducing more potential failure point to the coolant system.

 

I don't think the miniscule rise in overall temps is an issue.

I searched the interwez and went down a rabbit hole. People have the same concerns we all wonder about leaks and this and that. also people have this on there car and things seem to be just fine. He put a ton of research into this and he seems to be the man on this. I am going to try it. Might just order another short block just incase haahahaah .

I think, like most others, it isn't gonna hurt. I would also prefer it wasn't silicone. I'll likely end up with it at some point but I'm not in a hurry to drain the coolant. Might also switch for a cut to fit rubber hose.

 

But yes everything I've read makes it seem that Dom knows his stuff. If you read his install instructions, on the first page it talk about other ideas he currently has that sound interesting, like the variable power steering.

I'm about to install a diy kit. Here is what I bought:

 

1x M20x1.5 to -6AN fitting

1x 20mm crush washer (94109x20000 honda oem)

1x -6AN 45 degree fitting

1x 5/8"x5/8"x3/8" tee

1 ft 3/8" coolant hose

1 ft 5/8" coolant hose

2x clamps for 3/8" hose

2x clamps for 5/8" hose

 

My plan is to not cut the oem heater hose and instead use a small chunk of the 5/8 line on one side of the tee and then the oem heater hose on the other side.

 

This is essentially the same kit as the VEMS tuning cooling kit. They use Phenix Industries AN fittings. The -6AN is a little smaller diameter than the Dom kit. According to VEMS tuning, the -6AN fitting is within 0.010" of the optimal diameter but uses off the shelf parts for simplicity.

rhino, did you finish the install?

 

 

I just read on another forum that the overall cooling temp, for one forum member, decreased by 5C. Curious to hear if you see the same thing.

I didn't yet. Work is always busy and the current situation makes it more difficult to work on the car since I'm an indefinite stay at home dad while still having to work from home.

My goal is to get some time on the car. I need to change my rear wheel bearings, sway bar bushings, add cooling mod and clean aos/replace the hoses.

no worries. also working from home here. Been doing that for a while though. But this time, with 3 little kids running around

BTW I did buy this kit and will have it installed with all my other parts.

Nice.

i watched the videos and looked at the engine when it was apart. I still think it's snake oil. I'm not going to buy it because 30k on closed deck engine says no problem.

 

Dropping 5F on 1 cylinder only to raise temperature on others seems like the wrong approach.

 

Although I am thinking about going to an external water pump with multiple flow paths. Seems like a more uniform delivery of colder coolant to all parts of the engine would be better.
