    Transonic combustion

    seems too good for the motorists to have !!! I cant see the gov,or the petrol companys actually going along with it just yet, maybe 12 15 years, just think of all the lost revenue the will loose, would be good to actually have some on the road, to put the sceptics at rest !!! regards marcus...

    Piston damage from not enough ignition timing?

    Intresting thread this, but no one has said BMW has had problems with its cylinder bores, 6 8 and 12 cyl ones, so the ladds in the local BMW garage say, some thing to do with the ..coatings.. on the cyl wall deteriating,. wonder if this could be it,!!! Marcus One does nae have to know how...

    Radiators? 1 core 2 core, cross flow, etc...

    I totally agree with Izmus and Pat, getting the air out, is as good as ,or better than a rad change the faster you go, the more air is forced into the bonnet/hood area, thus raising the front of the car of the ground also you need a good tight fitting rad shroud, so that any air that goes...

    MBT (Minimum Best Timing ?)

    Hi all, one thing that most people are missing , is that the best timing at one particular rpm site, will not be the same at a site further up the rev range Ie, little throttle opening , at 4000+ revs, will get away with alot of advance but a lot of throttle openning, IE WOT, will need a lot...

    Camshaft /Tappet settings

    Ok ,ladds , been doing a bit of detective work here, and also got some good feed back, from some ..cam manufacturers.. but one thing is clear, the gaps that are given with a cam, all vary, as to what the cam grinder thinks/wants some say that the gap is needed to ..take..up the gap on a ramp...

    Camshaft /Tappet settings

    One thing i forgot to mention, dont no if it affects other engines, but the ..rocker gaps.. get wider by about 1.5-2 thou, when the engine is hot depending as to how hot it is, then the gap is bigger its a cast iron head, block I would have thought that the gaps would ..close.. up, as metal...

    Camshaft /Tappet settings

    Mike,im with you on that, as i know that cams have take up ramps,the one i have has these on, it says so in a diagram, that was in the box, the cam runs solid tappets/lifters too tight and it puts undue pressure on the cam lobe. Franze, this is sound thinking, but dont rev that...

    Camshaft /Tappet settings

    Thanks Ladds, I seem to get the jist of it, I was running the cam at 17 inlet, and 19 ex, but on recomendation, from some one, who said that cos im on , 1.65 rockers, instead of 1.50 ones, then the gaps should be opened up to 19 and 21 as higher ratio rockers need more clearance, this...

    Camshaft /Tappet settings

    Thanks for the intrest, but I dont think Ive got yhe answers im after!!!! Ivymike, youve come close, by saying that the bigger gaps in the tappets/ [rocker arms ] as we call them over here, are for an engine with more power, i can see where ye coming from with this, but read below. Pat, i...

    Compression ratio and balance factor

    This may be a long shot, but it happened to me once, has ..both.. the heads been skimmed the same amount,!!!! you say that you shortened the cylinders, is this normal way to go with Harlys,!! as shortening the cylinders, will result in the pistons sticking up past the gasket, may be...

    Camshaft /Tappet settings

    Can any one tell me why the gaps on a upgraded camshaft are bigger than on an OE one eg, standard TR 6 , 35 65 35 65, 250 cam lift, 10 thou clearance, after market cam, same duration, but a little more lift, 25-40 more, but any thing from 16 to 24 thou clearance, this is even if the cam is...
