probably not

That's what I'd have thought, and I think the conclusion was last time it was brought up. That's why I'm quite interested to see what Simon's friend says

If it was that easy with no bad effects then Fuel companys would have already added it to the fuel.

Maybe they do... there are 2 'performance' diesels on the market I am aware of and tried. Both claim cleaner engines and a few miles extra economy per tank (sound familiar?). There are MANY surface tension modification agents -of which Acetone is easiest to acquire for you an' me (and very non-toxic compared to others that can make the liver into a sponge).

All in all, they ARE using the same idea, and ripping us off (eg Acetone adds 5 pennies a tank. BP Ultimate Diesel adds 2 quid a tank) they ain't stupid

I'd also be very very wary of using it on a modern, high-performance diesel engine.

A lot of the NASCAR teams are using it. My engine is that used in the Mini One-D. A 1.4 turbo intercooled gem Take a while Googlin the method. It will protect such engines, not harm them. Your injectors will be clean and water-free. Cold starts better than ever.

It is many factors too dilute (50ML per 40Litres max) to ever harm anything plastic or rubber.

My concern as well, lubricity is an important property of a fuel and adding a solvent can't be good

Too dilute to act as a solvent (diesel is awash with fine lubricants) it only acts as a surface tension modifier.

I can assure you they are not

Tiny things can have a huge impact. A few thousands of an inch imperfection has some o' you keen overclockers lapping things smooth and reporting improvement. A bit of Polonium 210 the weight of a single Phosphor dot on your LCD kills one and pollutes swathes of London.

I forgot to add, the benefits on Petrol engines exceed that of diesel btw. No effect on smoke but 'knock' and 'pinking on load' can be reduced, as well as power/torque gain.

There does seem some interest here. Overclocking fuel what next

Well BP are notorious for their honesty I suppose. They will be as forthcoming with their recipe as Burger King.

Its not that important. try it or don't. Its old hat now in many motoring forums. Not one single chronic user has reported a problem now well over a year. Says it all.

Tuning box. But be careful, you don't want to map it too much. I'd start with 20bhp then move to 30. Anything too much, your clutch will start slipping.

megakid · 14 Feb 2007 at 12:48

So no-one has heard of the resistor mod? I thought that was a fairly simple mod just to trick the ECU into thinking there was more air and hence adding more diesel? I'm sure Jez had one on his Leon TDi so Jez, are you about

?

I know it was frowned upon by some members but for what I want (a temporary thing until I sell in July) it might do the trick!

I'll be eagerly watching to hear back from Simon regarding the acetone trick.

Jez · 14 Feb 2007 at 14:35

I wouldnt go doing a DIY mod mate to your engine. It works, certainly for VAG engines (there are different variations depending on model) and it makes quite a difference, but it also makes the engine run very rough and smokily. If you want more performance then you need a proper remap really which will adjust both fueling and boost.

Simon · 14 Feb 2007 at 15:01

Hi Simon,

Thanks for sending that through, it's been on the net for a while, I think I first read through it about a year ago.

It's all a bit far fetched (20-35% improvement in FE is just bonkers) I'm afraid, that's diesel-like efficiency from conventional gasoline operation which just does work thermodynamically.

As for durability, the concentrations that they're talking about won't really do any harm, any more than that and the elastomers in the fuelling system might suffer, more still and you'll probably start getting excessive upper cylinder wear from wall wetting.

Happy to talk through if you like.

Cheers

i've just been to see my mate at ford, he's a mechanic and is in charge there, he said if you have warranty on your car (which i have) then don't do it, even if you don't have warranty, it's not really worth it unless you don't care about your car, he said yes, it might work, but with the pressures going through a modern diesel engine, it could damage it or the fuel pump could fail and your looking at a hefty repair bill.

Apparently it 'works' by making the micro-droplets that come out the injectors come out as even smaller droplets, so improving the efficiency of the burn. Reduces particulates from the exhaust and stops that diesel acceleration smoke as a side-benefit. Can't prove that one way or t'other, but the extra torque and economy are defo there. Been using it 18 months no problems.

i thought acetone was just a poor mans octane booster?

i didn't think it had anything to do with the size of the injector atomised particles :confused:

Linz · 14 Feb 2007 at 22:07

In no way does the small amount affect the octane in either fuel. NASCAR use it to raise octane, but in correspondingly HUGE amounts -a totally different goal.

When you modify the surface tension of a liquid, it will mist finer. The spray from the engine injectors is a far finer mist. that's how the tiny amounts of Acetone work here. Anyone babbling about octane is confusing it with a completely different method (eg NASCAR, etc) that has nothing to do with the 'tiny amount' method.

Do you see?

There's plenty to read on this, eg:

Linz · 14 Feb 2007 at 22:10

Compare pouring a glass of unleaded on a candle. Impressive. Now see a fire-eater spray the same amount of fuel over the flame Far more impressive -a mist mixes fuel/oxygen better. Finer the spray, more oomph, and burns more completely with less particulates.

For diesel tuning boxes, you wanna go HERE and speak to Andrew888.

Those are his forums, his website, DTUK is here:-

http://dieselbox.co.uk/

I have one of his CRD2 tuning boxes fitted to my 3.0 V6 Vectra CDTi SRi.

Its simply incredible!!!.

Its boosted the power from a stock 177bhp to 220bhp and 450Nm of torque, and the mpg got better as well. Now getting around 40mpg when driven normally, around 35 when foot to the floor.

I've got it set on map 1, the lowest one, called "Harry". I've not tried any of the other maps, but I'm looking forward to trying map 4 "Sally" next week, a quick change of jumpers within the CRD2 box is all that is required to change maps.

"Real on the road" performance has been increased tenfold. Putting the foot down in 4th gear feels like the car is in 3rd gear etc. I've embarrassed quite a few "so called" hot hatches since, when they come up behind you and see the CDTi badge on the bootlid......LOL!!!. Last one was a Civic Type R. He got a wee fright, shall we say?.

Register on the forums there and check the "Rolling road results" section for any evidence that you may need to fit a CRD2.

Couple it up with a free flow K&N panel filter and your sorted.

The CRD2 boxes take 5 mins tops to fit and can be removed and the car put back to standard in the same time.

Give it a look see m8, you wont regret it. My best m8 recently drove my Vectra and was so impressed, he bought a CRD2 for his Mondeo ST diesel.

Linz · 14 Feb 2007 at 23:09

The new Vectras are fantastic to drive. Tried a 3.2 Elite, bloody marvelous, then the facelift VXR Estate, ******* mental. The 3.0 CDTi seems to have masses of torque, nice one.

psalliss · 14 Feb 2007 at 23:18

well worth it mate makes a massive difference to the car. ive got a omega 2.2 dti which before o had it chipped was flat chipped its miles quicker revs cleaner and has for more torque.
