That only helps for carbon that is built up in the path of the valves. Any RPM will do that. The problem is the carbon that builds up in the well surrounding the valves that restricts air flow. Heated oil is what creates it. More heated oil does not correct it, quite the opposite.

 

Have they done any improvements to stop this in the 2011 or 2012 MCS?

 

Walnut shell blasting....

Does the 2011 & 2012 need it, who knows!?!

 

I know that Water/Meth prevents it, but soon I will be removing the inlet manifold to see if it actually removes any.

I'm excited to see if it has made a difference.

 

Water/meth does work and IF warranty is not an issue AND you can get the consumables AND KEEP THEM ON HAND FOR LONG TRIPS it sounds like the ticket. For the Track it is wonderful. For around town, wonderful but for long road trips how much meth can you carry??? How many miles per tank of meth at freeway speeds???

Let us know if it really works!!!

What year MINI are you driving??

 

Oh I know that it works, but I want to know if it can actually reduce existing buildup.

You don't need to keep the consumables, you can turn the threshold up, or you can stay under the threshold, you can run a small jet, you can even run straight water if you run out, or you can get the double-capacity race tank.

Freeway speeds under low load, won't use a thing, unless you turn the threshold down.

My water/meth tank (double capacity) lasts well over two tanks of fuel, and my threshold is down, and I run a big jet.

I will definitely let you all now if there's a difference. My MINI is an 08/08 f-JCW (or in US-speak, an 09 f-JCW)

 

Wow! Very good info on that rate of consumption It puts the idea closer to the front of my list than I thought

What water/meth kit are you using??? I was toying with the idea of an Aquamist system.

 

I bought (and sell) the Howerton Engineering HFS-3 (which is basically an aquamist system with a couple changes). I really did my research with that, as it wasn't a small investment.

Yeah, you can set up the system to barely use anything.

BTW, don't know if you've seen this, but it makes for good reading if you need convincing. http://howertonengineering.com/mini/ (read the part where it says R56 dyno graph)

 

on long trips use windsheld washer fluid

 

That was the unit that I was considering. Did you sell yours?

JPMM: Windshield Washer Fluid!!!???

 

alcohol and distilled water

 

That makes sense. I was thinking soapy water!!!

Isopropyl 99% ???

 

Oh no, I haven't sold mine. I run a company called RennSport Racing down here in Australia. I have fitted three kits: my car, my brother's car, my business partner's Golf GTI (Rabbit Mk5). We are about to install a fourth kit into a ford focus ST/XR5 Turbo

I have also sold a kit to another JCW owner who is yet to fit it.

Don't run isopropyl alcohol. Richard Lamb of Aquamist doesn't recommend it.

You can bring an additional container of water/meth with you, nothing wrong with that, but I honestly don't think you'll need it, as you won't use anything on low load, long distance driving.

Windshield washer fluid is usually meth and water, but they tend to use dyes and detergents that you don't really want running through the pump. 99.9% pure meth and distilled water is ideal.

 

I understand now, thanks.

Yes, as pure a mixture as possible.

Did you locate the Tank in the boot and run the lines forward to the jets and controller?

Direct Injection really caused a big problem for those of us who care!! Audi/VW, anyone who has D.I. can count on a carbon buildup on their valve stems and cold side of the ports and as was said earlier a good Oil Catch Can will help.

What cans are people using? Trying to locate a can in the engine bay is pretty challenging!

The 2011 refresh engine has only 1 hose on the valve cover and it runs to the turbo so BMW?MINI did something different. I am very curious as to what the valves look like after 10K miles or so.

 

I have an Auqamist on my turbo bike and I thought I read that windshield washer fluid was OK? I'll see what I can find

 

Sorry, I didn't mean it to sound as if windshield washer fluid is bad. But if you can get one that has a few additives as possible, that's better.

Isopropyl is no good.

 

What type of alcohol are they using if not using methanol?

A turbo bike? Just sounds fast without knowing anything about it

 

Yes, the tank is in the boot, and the fluid line runs through the boot floor, under the car (along the fuel lines) and up into the engine bay. The electrical wiring runs under the interior trim.

I have the BSH can currently, but I'm working in conjunction with Czar to get him to make a catch can with a coalescing filtration medium, and a correctly engineered can that matches the flow rate of the PCV system.

An interesting fact: Lexus apparently has a secondary fuel injector in the inlet manifold that sprays intermittently, purely for the purposes of stopping carbon buildup.

 

Interesting about the coalescing can. I saw something about it in another Thread. Keeping the oil out of that area is a good idea!

The Lexus but not the Toyota??

In Australia do you have to run unleaded fuel? What is the octane?

 

Yes, we do have to run unleaded fuel. We have a choice between 91, 95 and 98 RON (which is not the same octane rating system you guys use, I think you use AKI). I think that'd be equivalent to your 87, 91 and 93 respectively.

I'm not sure if Toyota use direct injection on any models, but I'm sure if they do, they'd probably use the same system.

Keeping oil out of the intake tract is indeed a great idea

 

It sounds like a real lock step movement in fuels! Are you being forced to use 10% ethanhol with talk of raising it to 15%???

 

We do have a choice of E10 (10% ethanol) in quite a few places, and E85 (85% ethanol) in very few places, and I'm not sure if we'll be going up to E15, but I'm sure we will.

At one stage we had the option of 98 RON + Ethanol, which equated to 100 RON

 

Do you guys use corn for the ethanol? Just doesn't seem right to use food to put into a car....

The percentages are the same here with the farmers being a big lobby to use their product as opposed to another source of ethanol.

 

I would say that the majority of our ethanol would come from sugar cane. You guys farm a lot more corn than we do, we're big on sugar cane production here lol

 

I suppose that makes sense being as you are more tropically located.

Keep us Posted as to the 2011+ engines look after a few thousand miles get put on them, if you see any of them in for work.

Thanks for the info!
