Rotary Carbon Clean?
 

Guys

Another nube question, but as this is my first rotor im not sure bout anything. Is it ok to run a carbon cleaner like subaru upper engine cleaner through a rotary? Or is there some solution or additive you can put in the fuel tank? Any help much appreciated :)

Just rev the shit out of it!

yep yep lots of redlining. :)

r u guys for real? seriously? wont that wear the engine out quicker?

"A redline a day keeps the carbon away!":boink:

think about it like this, they put the redline there for a reason, dont go past it and you wont have problems:icon_tup:

Redlining reduces build-up but it doesn't REMOVE what has already built up. Just run some BG fuel system treatment every 6 months for preventative maintenance and you wont have to worry about carbon build-up.

SeaFoam!

Anyone heard of or ever used this? what do you think?

As long as the engine is nicely warmed up, it's perfectly fine.

You're thinking of weak-ass piston engines that get all whiny about high RPMs.

haha

If you REALLY don't want any carbon build up ever, run water inj.

Can you use seamfoam without replacing spark plugs or anything else, or is it a must? Thinkin about it for a future project....

I took the FD to get dyno tuned a couple of weeks ago...I can tell you for a fact that carbon will be cleaned out, a couple of high revs in 4th gear produced the thickest black smoke I have ever seen followed by clear heat vapors. I think I granny shift too much

its deffinatly true. i coated the front of my buddies z in black smoke the other day cuz he was tailgating me, he learned not to do that again :lol:

Read the Rx8's owners manual and what it recommends :)

Then if you still have problems use seafoam. After that maybe water injection.

RX-8?! nobody cares about that rotary sedan! hahaha:lol:

I have read this before. i was actually going to start a thread about it to see how many people are doing this.

I'm interested in doing this, so if someone has done it before. What vacuum nipples did you use? i know there are two on the passenger side of the upper intake manifold, but the writeup says to use some on the lower. Does anyone know if the two on the upper intake manifold go to the two separate rotor housings or if they both go to the same one???

or if you have any other tips or advice, i would appreciate it before i go and do this.

He's indicating that it might be preferable to use a LIM nipple, but for convenience I've used one of the two on the UIM. I don't think it makes alot of difference. I also used distilled water since I had some in the shop and the local water is pretty hard, but again it probably doesn't make any difference. Keep an eye on your exhaust as it will get hot, but that's generally a good thing.

well i was planning on putting a vacuum line on both of the nipples on the upper intake manifold and t-ing them together and putting that in the water. would that work? would that get water to both rotor housings??

^yes, that is what is says to do if u followed the link

ok, i was just wondering if i could use those or if i had to find a couple on the lower intake manifold. if there even are any there, i dont know.

thanks though.
