[QUOTE="Cowabunga, post: 4507194, member: 718"] These are Same's own design and are the 'Pantherised' versions of an earlier design. The Pantherised engines have the immersed camshaft actuated piston pumps rather than the Simms-type timing case driven external in-line pump previously used. They also have under-piston oil spray cooling to supplement the air cooling of the upper combustion chamber and cylinder heads. Anything else?……….. Oh yes, hyper eutectic alloy pistons. Not sure whether there was anything unique about the pistons at the time but it was mentioned in their marketing bullshite. Very economical engines but lacking somewhat in torque backup compared with more modern designs today. Pantherised engines were made in three, four, five and six cylinder versions with two bore sizes available. I know one was 98mm and I think the other was either 102 or 105mm, can't quite remember which. The five cylinder was interesting because at that time only Same and Fiat fitted them to tractors as far as I know. Both around 90hp. An example of the Same is the Jaguar95. I had a Tiger Six 105 and a later Laser 130. The Tiger was an especially impressive performer in its day. The Laser was hampered by a heavy clutch pedal and a transmission that seemed to suck power in the two higher gears for some reason. Although still only 30kph, the Laser had the same front axle as fitted to my Titan 160 complete with large brakes in each front hub. These Pantherised engines liked hard work from new or their extremely high quality cylinders and piston rings would glaze. Once run-in properly on that hard work they are extremely reliable and long lived engines as long as the fins are kept reasonably clean to avoid overheating. I believe I'm correct in saying that each engine manufactured was partly run-in at Treviglio in their several test chambers before fitting to a chassis. That was, I think, quite innovative in the late 1970's and early 1980's. The one exception is that they are difficult to time properly once upset. There was one locally, a Trident 130, that kept blowing fuel injectors out for some reason. I don't think Riverlea, the dealer, ever did cure it. And no, I didn't get a single morsel of the above from Google, so :finger: to those that believe I do. [/QUOTE]
