Spitfire Multispark... any good??

Heard a lot of good things about this Spitfire Multispark on a few forums and websites. Has anybody fitted it to a P6 to any decent results?

If you're not aware of it, it's basically a coil-to-dizzy lead with some sort of oscillation device in it that converts 1 spark into 5 for multispark performance. It claims to improve economy, increase bhp, lower emissions, lengthen spark plug life, improve cold starting, solve world hunger, the lot!

I'm always a bit skeptical of these sorts of products. They promise the earth and always have a clever little rig at motor shows to *prove* it, but I'm only interested in improvements in a real-world application, rather than in principle- clever as they are.

I can see that there would be benefits in theory, especially on a carburetted engine, but has anyone had any success?

Snake oil IMHO

surely we set the timing for a spark to arrive at the time we require it, we want the spark to be as strong as possible at that exact time, not 1/5th of the power with the majority of the spark occurring well after the required time.

multispark applications in engines are to create multiple flame fronts in the combustion chamber for increased burn, one spark plug with 5 sparks (four of which occur after the event hoping for sloppy seconds) would not create this, the acid test for me is always along the lines of 'is it used in professional motorsports' and is it used by car manufacturers who given the opportunity to increase BHP and increase economy would jump at the chance....... and nope I dont see it!


ive seen one of these 'rigs' at a trade show many years ago, we watched the demo, asked some probing questions that the 'expert' could not answer and prompty walked off.


if anyone wants me ill be in the garage fitting a 'fuel cat' full of lead balls into my fuel line :LOL:
 
do not buy this crap , im amazed that these people are still in business , i put them on my gs1000 years ago and it ran like a bag of crap , so i decided to smash open one of these things to see what was inside ,oscillation device my arse inside was a NAIL!save your money for something decent, regards rich

That's a good rule of thumb, i'll remeber that one when explaing why putting a one way air valve in the breather system is pointless. :)

yes we spent lots of time when i build WRC engines fitting those valves into the system....... :LOL:
 
Iridium Spark Plugs

Just seen one of these things for sale on ebay for £25 and it reminded me about this post!
I agree with the motorsport test Whitewash came up with- makes very good sense!

Here's another one for the panel: Iridium spark plugs.
Now they ARE used in motorsport, and a lot of classic mags/forums, etc are talking about them quite a lot. But are they beneficial in a real-world setting? Now, I get the principle, but is concentrating the potential diff with advanced mettalurgy techniques really going to make a justifiable improvement to economy/potential power output in a 40yo TC that probably only puts out 75bhp as it stands..?

I remain skeptical until proven cynical!

Probably a hell of a lot more to be gained from pulling the head off, lapping the valves, setting the clearances properly, de-coking the chambers and fitting new piston rings and a quick cylinder hone. But that involves loads of work, not just bolting in some fancy plugs. :LOL:

I remember Dave Walker saying that if you've got a good spark that ignites the mixture, it doesn't matter what else you do with the spark it won't make any difference.

What you do get from some of these add-ons is improved reliability and reduced maintenance, especially something like replacing the points with a contactless electronic system. Now if somebody could make a dizzy cap that had the coilpacks built in, you'd remove the king lead and rotor arm from the system too.

I reckon these are made from:

Half a dozen or so (depending on the cc of your vehicle of course) Mentos Chewymints wrapped individually in kitchen foil.

The foil wrapped sweets are then placed inside a bit of steel mesh and the ends twisted - you can buy rolls of this at Wickes or B & Q.

Almost as good as the 'fuel saver' magnets that clip onto the fuel line in the engine bay. :roll:

Solid gold. :LOL:

are you meaning that it isn't a length of hose with a cat stuck in it?

Solid bullshit, that advert is hilarious, so utterly full of crap!
 
...as we are in the lounge, talking about snake oils -

What about "Two-Stroke Oil put in the fuel tank of a diesel car" ?

Any opinions on that ?

Regards !

(its a holyday in Germany, the weather is SMASHING and I got a late shift - go figure... . Some pity PLEASE - and a very nice day to YOU !)
 
...right, that is what everybody is trying to find out :)

No, seriously:

There are more than a few people that put two-stroke-oil in their diesel, be it a mechanical pump, common rail or whatever engine.
Google for it and you will find more pros than cons, and the smallest of problems is blocking of XXX as the stuff sems to burn almost residue-free (better than diesel, as they say) indeed and will on its way clean AND lubricate ("...you get two benefits for the price of ONE (drumroll/cymbal crash)!")

I found that there are some genuin petrolheads (AND dieselnuts) here so I thought that somebody might give her/his experience... .
 
Pete's our man for this sort of thing, runs his Pug diesel on any old cr*p he finds lying around, I'm suprised he's not been on yet and given us chapter and verse ! :LOL:

What do you mean crap? :D

I run on Plant Oils in the Pug XUD9TE Shooting Brake Bodied Flyer!

Regarding the use of 2 stroke oil in a diesel.....

It can be done and does indeed increase the lubrication properties which can help
the injection pump when using 'Slightly Unusual Fluids' to propel the vehicle...

Before anyone asks....

You can use 2499 litres a years of Plant Based Oil without paying fuel duty
You can use anything as an additive provided it does not exceed 3% by volume.
I would NOT advise using Red Diesel as an additive!
I use Acetone in veg oil to help break down the molecular bonds.
 
im presuming that if i run my diesel on cats then the engine would break them down meaning that kittens will come out of the exhaust pipe?

not only will this solve the stray cat problem, but the car will really purr and be quicker as it will go "meeeeoooooooowwwwwmmmm" as it goes past.

plus it would leave a trail of cute kittens behind it, leaning that ladies can go all soppy over the kittens and leave us to work in our garages


world saved, and all before the pub opens! tomorrow i will solve climate change by leaving my fridge door open
