Joris Posted March 30, 2012 Share Posted March 30, 2012 I saw this on eBay and was wondering if anybody knows if this really works? http://www.ebay.co.uk/itm/SPITFIRE-MULTISPARK-IMPROVED-IGNITION-DODGE-WC51-54-/350247567224?pt=UK_Cars_Parts_Vehicles_Other_Vehicle_Parts_Accessories_ET&hash=item518c61bf78#ht_755wt_1163 Quote Link to comment Share on other sites More sharing options...
Spood Posted March 30, 2012 Share Posted March 30, 2012 I'm not sure Joris but I think a device like this has been discussed on here before in the dim and distant past. I think probably Mr Elliot would be the man to advise on this. Quote Link to comment Share on other sites More sharing options...
Rick W Posted March 30, 2012 Share Posted March 30, 2012 I wouldnt bother Joris, Spitfire plugs came onto the scene a few years ago, I tried them in a few cars and they made no difference. Just stick with good quality spark plugs, NGK etc. Quote Link to comment Share on other sites More sharing options...
fv1609 Posted March 30, 2012 Share Posted March 30, 2012 Joris there is some coverage of these on page 13 on of http://www.hmvf.co.uk/pdf/IGNITIONMATTERS.pdf Including x-rays of these devices revealing the inner secrets of two head to head self tapping screws & how to make your own using an old button!

Joris Posted March 30, 2012 Author Share Posted March 30, 2012 Thanks Clive and the rest, I'll take a deeper look at it! Quote Link to comment Share on other sites More sharing options...
Tony B Posted March 30, 2012 Share Posted March 30, 2012 The principle works, another air gap can boost the spark. I have one knocking about if you want to try it. I have now got one of Frank Jolley's electronic ignitions in my WC51 and one in post for the WC54. They are known to work. Quote Link to comment Share on other sites More sharing options...
Rick W Posted March 30, 2012 Share Posted March 30, 2012 As Tony said, I think you are far better off buying one of the EI kits, Quote Link to comment Share on other sites More sharing options...

Rover8FFR Posted March 30, 2012 Share Posted March 30, 2012 In my younger days Spitfire plugs was a trend in Motocross and all the big US factory teams used them, so all us budding Rick Johnsons did too. I can't say it ran any better than an NGK type R plug, but I remember it was more sensitive to fouling and Krap, so soon switched back to NGK Race Plugs........... Hope that helps............. They would probably only give benefit at the rev range a Motocross bike worked best at, between 9,000 and 12,000 revs.. MV engines would have hit melt down way before that range.......................................... Quote Link to comment Share on other sites More sharing options...

Tony B Posted March 31, 2012 Share Posted March 31, 2012 I'll have a look for my old one if you want. It's sitting doing nothing. There might be one on Katy, she is getting a Frank Jolley special as well. Quote Link to comment Share on other sites More sharing options...
Joris Posted March 31, 2012 Author Share Posted March 31, 2012 Well actually I've got a more modern (waterproof) ignition now but it seemed interesting if I ever wanted to change it back to WW2 spec. Quote Link to comment Share on other sites More sharing options...
Joris Posted April 11, 2012 Author Share Posted April 11, 2012 And this? Does this work? http://www.ebay.co.uk/itm/Dodge-WC-G-505-Fuel-Cat-Stabilizer-Keeps-Fuel-Fresh-/180447459705?pt=UK_Cars_Parts_Vehicles_Other_Vehicle_Parts_Accessories_ET&hash=item2a0381b979#ht_2230wt_1182 Quote Link to comment Share on other sites More sharing options...
ajmac Posted April 11, 2012 Share Posted April 11, 2012 (edited) I wouldn't bother to be honest, just run unleaded as it comes out of the pump, you may have hardened seats, as the US Ford Flathead V8s had hard valve seat inserts up until the 1950s, perhaps Dodge did too. Either way, it can take a lot of hours on an engine to get significant valve seat errosion, depending on how you drive it. Back in the 90s a group in England paid for a test on a Mini A-Series engine and ran it on a test bed at high RPM on normal unleaded, it did suffer seat errosion but it was equal to a hell of a lot of normal driving before it became noticable. With the money you save not using additives, you can get valve inserts fitted when you do a rebuild. It only cost me £125 to get my 2.5 Triumph straight six head done....10 years ago.
