Is there any major reason why not to try this method of de-flooding an FD3S?
Quote from: rx7aberdeen;66040Believe it or not if you pour 3/4 of a can of coke directly into the inlet manifold pf a flooded rx7 and turn it over the car will start did it myself and witnessed what i thought was a miracle! has to be coke, cant be diet and has to be an rx7 to work!!!!!!!!!
Its a quote from the FAQ section but no reply on effectiveness or engine safety from a tuner?
Many thanks
Personaly..... I wouldn\'t do it!
If it was a carbon locked engine then it might work in ridding the engine of carbon - coke is amazing at stripping crud off metal. One of the ingredients of coke is Phosphoric acid - the active component of Jenolite.
I\'d be reticent to try it - but can see why it might work in some cases.
i def wouldnt have the balls to try it
coca-cola doesn\'t compress well, so if you pour 190ml (roughly 3/4 of a can) into the engine and it all ends up in one chamber, surely something is going to go \'pop\' when you crank it? i\'m pants at maths, but i\'m thinking when the chamber is at full compression the volume is a lot less than 190ml.
It would smell sweet coming out the exhaust lol!! ;)
To me that would just be a waste of good coke :rollin

You can\'t be serious?!!!! As already said before. fluid doesn\'t compress and something will go bang(expensively). Take the plugs out and crank it over AFTER removing the egi fuse(3rd from the front of the fuse box under the bonnet) or you will definately unflood the engine-and the rest of the car-with a large fire. If its that bad, after cranking it over with the plugs out, leave it a couple of hours and try again. Get some new plugs while you\'re at it.This advice(pouring coke in the manifold) sounds remarkably like the one on an american site I\'ve seen about polishing the ports by tipping sand into the inlet manifold, it must be the funniest thing I\'ve read in years!!! I suppose using a few grammes of heroin would do the same as some coke though its mighty addictive!!!!
I reckon two lines will do the trick......worKs for me....HAHAHA!!!
As coke(aCola I mean) contains phosphoric acid, do you think lisurgic acid would do the same thing?(Am I getting silly now)?!!!!!!
If you pour coke into a flooded engine it might work...but then your engine is flooded with coke :D
Er...isn\'t the fundamental principle of hydraulics that it\'s very difficult to compress a liquid :3Confused? And we all know how powerful hydraulic pressure can be....just look at a JCB! :D So surely hydraulic pressure + rotor seals = Boooom-splatter! :Hammer

probably more like squish, splurge and some contaminated oil to boot. I\'d drink the coke. :guinness
:Giggle:Giggle:Giggle maybe you should try redbull :cheersit will give it wings lol:rolleyes:
1/2 cans coke maybe but it will still flood it just not with fuel
I\'m glad to hear I have the same opinion as everyone else!
Another one to throw into the discussion is:
Rotaries cannot suffer from hydraulic lock?? True or false?

Water instead of ATF for decarboning
Hey y\'all, I was talking to Rob Golden at Pineapple Racing last weekend and asked about his experience with the ATF treatment. He said that he prefers to use water.
1) works well, steam is very effective at breaking up carbon. Gives a noticable power gain.
2) easier and quicker, just pull a vaccuum hose at the dynamic chamber and pour 2 liters of water in (no kidding) while the car is reved up and down above 4k rpm. Just pour it in as fast as you can without killing the motor.
3) doesn\'t fowl plugs, O2 sensor, or clog the cats like ATF (actually cleans them).
I gave this a try last weekend and here was my experience:
I pulled a vacuum hose off of the dynamic chamber and placed a fresh hose in it and submerbed that
hose in 1 liter of water. The motor sucked up the water over about 3 minutes or so. I had to give the car gas to keep it running; about 4 k rpm most of the time, but I varied this quite a bit between 2k and 6k rpm. Obviously the car ran rough during the treatment. Towards the end of the treatment I noticed smoke coming from the side of my car near the back wheels and a burning smell. I looked under the car and to my suprise the cat and muffler pipes were glowing orange hot! (it was about 30 minutes before dark) I don\'t know wtf was going on but it got my adrenaline going! I shut the car off and let things cool down.
After things cooled down I took it for a spin. The car runs better, idles better, and has a bit more power (feels like 10-15 horsies, but this us just a guess). It also has noticeably better response at part-throttle. Feels more torque-y. So, it works, but I\'m worried about what all that heat could do to my new mufflers and cat, although everything seems fine now.
Anyone else ever try this?

Would/has anybody done this from the uk?
What are your opinions on both these statements?:

i know this has been discussed alot here but i found this and was just making sure things were ok before i do it coz i know my mates car kinda fooded and he bent a con rod in his jeep just dont want my engine to go pop or some thing bad to happen it all
NOTE • Hydrostatic lock is caused by the entry of substantial amounts of water into the engine through the air intake system and subsequent contamination of the fuel system. Hydrostatic lock most frequently occurs during or just after fording. Water is forced into the air intake system, drawn into the engine, and effectively "locks-up" the engine.
Hydro-Lock
Hydrostatic lock, hydraulic lock, hydro-lock or hydro-lock occurs when liquids enter an engine cylinder.
This can occur from a coolant, oil or fuel leak,
but the chief cause is drawing water into the engine through the air induction system
(air filter, intake manifold). Internal combustion engines must employ a compression stroke to compress the charge.
Liquids are incompressible; the presence of a liquid in the engine cylinder during the compression stroke generates destructively high cylinder pressures.
Abnormally high cylinder pressures can bend and break pistons, piston pins, connecting rods, crankshafts and ruin bearings and can crack or break cylinder heads and engine blocks. Small amounts of liquids may pass through an engine cycle without causing damage. Hydro-lock may occur while the engine is running, the work of the compression stroke being supplied by engine\'s rotational inertia. Or a liquid may leak into the cylinder while the engine is being stored;
the work of the compression stroke will be supplied by the starter motor.

LOL wrong post for the wrong forum buddy. Rotary\'s don\'t have rods nor can they hydro-loc. Any water that enters the combustion chamber will flow straight through. Now if a really excessive amount goes in, the only thing that will happen is the engine will bog down to the point it stops running. Once you remove all the water from with-in the engine, the engine will fire right back up and be fine.
__________________
^^^Including this highlighted in red?
Heres my humble opinion once more. The swept volume of one lobe on the rotary is 201cc, the compression ratio is 9:1, therefore the combustion chamber including squish is 25cc approximately.A can of coke is 330ml,3/4 of that is 247.5ml. 1ml=1cc. You stick 250ml into 25cc and something has got to go.The opinion that rotarys don\'t suffer hydraulic locking is(in my opinion),BOLLACKS!! They have,at top dead cente, a fully closed combustion chamber. At that point, before ignition(yes I know,its already fired by then but just for theorys sake), the combustion chamber pressure is 132psi. Stick a fuel/air ratio into the mix and light it at the right time and you have cylinder/combustion chamber pressures of going on for a thousand psi-momentarily-(someone correct me if I,m wrong) then stick boost from the turbo into the equation. The point here is that air is compressible and the rotor will fire and move on with the expansion of the gases, the seals hold this pressure in the engine at that point. If you try to compress coke or water or even cat.... the engine will hydraulic whether its a rotary, 4stroke or 2stroke and something expensive will break.So, to summarise,the major reason not to put coke, water, cat/elephant/hippo.... into an engine is this:-An engine rebuild is THREE AND A HALF GRAND!!!!!

haha, well said!
The coke will come out round the insulating rubbers of the injectors.
I managed to completly flud a 13b (dont ask how) Was sure I had a fuel leak as after it was cranked over I would have fuel poring out underneath! After a lengthy deflood procedure and oil change, all was good.
Did I mention that I managed to flood a ....roen? I achieved this magnificent feat by totally ignoring the wise words of my better half(as in \'Don\'t drive through there you idiot, its too deep\')and promptly driving into 21/2feet of water. The ....ing thing stopped never to go again, mind you the expression on my missis\' face said it all- along the lines of \'YOU DICKHEAD!!!!\' Well I always was an impetuous type!!!
Hey Bob,
you\'ve fully answered my question, It shocks me that some people in the States have done this to there Rotary!
Many thanks

They are americans.... they shoot themselves when at war. they elected Bush as president. they lend over 5 times your income to rednecks... pouring coke into their car seems pretty senisble if you consider this :evillaugh

True True lol :yes
Sorry but you\'re wrong there waddock. The americans don\'t shoot each other the ....ers shoot our lads \'Sorry dude but we fly so high to keep out of range of anything that we can\'t make out who is friend or foe so we just shoot anyway and hope for the best\'. The american and british ground forces in the second world war called the usaf \'the american luftwaffe\' cos they were always bombing the allies.On a lighter note, did you know that a wassock was a wig for a bald minge? Its a good job my eyesight is stiil good or who knows???? Oh my real name is Bob Monkhouse so I\'ve heard \'em all before!!!!!!!
I think this water cleanup isn\'t chucking large amounts of liquid into the engine all in one go - at 4000RPM, the engine will be cycling through the rotors at 1/3 of this - so say abot 1300 combustion events per rotor face. By opening up a vac pipe and letting the engine ingest this water over a minute or two - it\'s not much water per cycle that\'s getting sucked in.
I\'d be reticent to go as far as sucking liquid straight in like this - proper atomisation of the water is what\'s needed - water injection - it\'s something that is done already. The amounts and time he\'s talking about are about double what you\'d expect with water injection whilst on boost.
There is a vid somewhere on MRC of this being done.
How long would the hosepipe have to be?
