I have seen this used on Subarus... Its a foamy type substance. Can be purchased from Subaru. Cleans out the carbon and varnish deposits in the upper engine. Makes a difference. Haven't tried it on any of my cars. Suspect the subarus need it because of the boxer engine configuration...

A lot of the older suby guys swear that the engines need regular thrashing to clean the top (should that be sides) of the engine out and keep the lifter noises at bay...

I think the main difference between SUEC and Carby Clean is that the Subaru stuff foams and hence doesnt just drain out the exhaust valve due to the effects of gravity.

All speculation tho as like I said... I haven't used it on MY cars...

I have used "top engine cleaner" but the stuff I used was made by Holden & is available thru Holden dealers. The idea is to rev the motor, then dump the stuff in until it stalls !!

sounds pretty harsh eh ?

The car will then blow plumes of white smoke - and I mean PLUMES of white smoke, for a good 1/2 hour or so after restarting the motor. It dissolves carbon deposits in the cyl head & piston crowns. Made a noticeable difference in 20 Y.O L20B Nissan four.

I'd rather fit a tin-oxide fuel catalyst to keep the carbon nasties away - That way you won't have the EPA chasing you (those plumes of white smoke leave a trail for 100m or so !)

Upper engine cleaner is really only good for carbon buildup. If you are having problems with detination or know that you are running overly rich and not giving the car a good hammering now and then, then it may be worth considering.

Carbon buildup will effectively raise your compression ratio (by reducing the compressed cylinder volume) so will therefore help performance unless of cause detination is occuring.

The carbon build-up bits will glow white-hot and promote detonation by spontaneously igniting fuel mixture.

    • If that's the wiring from the factory, I'd be inspecting the loom everywhere.   Any signs of that anywhere else, and seriously, I'd get rid of the car ASAP before the electrical gremlins make it worthless, or it goes up in flames on its own. That is scary how that insulation is failing!
    • I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies. 
    • It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest. 
    • Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks! 
    • It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers
