Peter Cobbold Posted January 10, 2017 Report Share Posted January 10, 2017 I loooked into the transfofmer coil he recommends , the Bosch GT40T. It was Australian and also no longer available. Peter Quote Link to post Share on other sites

Guest Posted January 11, 2017 Report Share Posted January 11, 2017 I am far too stupid to understand this. Or perhaps I didn't pay attention in class when this was on the black board (there was this really nice girl in my class THAT I can remember) Menno Quote Link to post Share on other sites
RobH Posted January 11, 2017 Report Share Posted January 11, 2017 A very interesting and comprehensive paper, thanks for the link Bob. I do notice he just talks about the spark energy from the different systems. OK it isn't the stated aim but the paper says nothing about whether there is any real benefit in terms of power developed on the road, as opposed to the bench tests he performs on just the ignition system. For the run-of the mill road TR4 with its 'agricultural' engine.....I wonder whether it would really make much difference? There's a whole load of other interesting stuff on the website he links to on page 5. Quote Link to post Share on other sites

RogerH Posted January 11, 2017 Report Share Posted January 11, 2017 Hi Graham, not sure if Dr,H has changed his web address but here is his OD logic box http://www.worldphaco.net/ Roger Quote Link to post Share on other sites
Grahamgl Posted January 11, 2017 Report Share Posted January 11, 2017 Hi Roger, His website address hasn't altered. He did a series of articles in TRAction a few years ago which was where I got the O/D controller circuit from. It cost me less than a tenner to make it. Graham Quote Link to post Share on other sites
TriumphV8 Posted January 12, 2017 Report Share Posted January 12, 2017 In my opinion the improvement of the ignition makes sense because older systems could not work like the Physics would request. The main problem ist that the ignition coil needs for a small time an electric pulse to build up the magnetic field that delivers the high tension when it breakes together. Related to a defined angle of each crank rotation this time will be longer at low revs what heats unnecessarily the coil and what will be shorter at high revs what may not "fill" the coil completely. This can easily be corrected with modern electronics and worth a look at. But I prefer to use it as a black box and fit and forget. The rest like free programmable ignition mapping is a nice add on and a very good idea when engine is modified or distributor is worn or other circumstances like fuel quality enforce a modification. Hotter cams will make the original part throttle advance a bit weak. Quote Link to post Share on other sites
DaveR Posted January 12, 2017 Report Share Posted January 12, 2017 One of the problems is the range of time the constant the coil has to work over. i.e long at low rpm to short at high rpm, its a compromise. Like many of the shortcomings of the earlier ignition systems these can be designed out in modern vehicle systems and as a result this will improve engine efficiency and reduce pollution. It has to be a compromise which most of us accept in our older vehicles for maybe originality and simplicity. Easier, cheaper and quicker to fix. That is providing the repro parts are up to it! Just my thoughts, Dave Quote Link to post Share on other sites
GT6M Posted January 16, 2017 Report Share Posted January 16, 2017 One of the best ways t, up yer IGN is to fit uprated parts, there a few choices like Hollow plug leads, thee,s save weight, and must be the ultimate sparky plug, dont forget, ye will need to clean yer plug wires too, as a dutty plug wire really saps power, http://kalecoauto.com/index.php?main_page=product_info&cPath=9&products_id=27&zenid=m-cgpbwo1p1f1Gugi,l-50 chrome here too,for them thats into Bling http://kalecoauto.com/index.php?main_page=product_info&cPath=9&products_id=29&zenid=-2YeniuphhtT4uaNLStRM0 http://kalecoauto.com/index.php?main_page=product_info&cPath=9&products_id=30&zenid=-2YeniuphhtT4uaNLStRM0 Zoom in to see the benefits of thee,s plugs, M Quote Link to post Share on other sites

I want to get this right as it might affect the product's elligiblability for TR Gold. - should I wish to propose it. Peter W Sorry OP this is off topic.
