3/4 Can Coke to cure flooded FD3S?

DMDRIFTING · February 11, 2009, 08:43:53 PM

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!!!

Bob Monkhouse · February 12, 2009, 04:27:42 PM

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

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!

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?
