rj Posted October 1, 2008 Share Posted October 1, 2008 It's been discussed a few times in the past, but at long last I've had a chance to throw a VHPD engine on the calibrated set of scales: 72.84kg This was the bare engine with MGF wet sump, coil pack, distributer HT leads and the bulky Rover alternator. However the engine was fitted with the lightweight Julian Weight Watcher Thompson cam cover. No flywheel nor any induction fitted. Removing the mentioned items would probably mean that a stock engine - with the ordinary cam cover - would weigh in at 68-69kg. An R500 flywheel will add 3,167g Jenveys... Hmmm... Haven't had them on the scales, but a guess would say 2kg incl fuel rail and injectors. In other words the engine ready to run weighs 75kg! I'm going to do a little work on the engine and will post the weight of it once I've finished. Link to comment Share on other sites More sharing options...
tweeky Posted October 1, 2008 Share Posted October 1, 2008 have a look to see if the MGF engine mount it still fitte, if so remove it and you`ll save 1.5 kg oily removed mine and fitted a blankilg plate a couple of weeks ago Tweeky In a purple haze Edited by - tweeky on 1 Oct 2008 16:58:31 Edited by - tweeky on 1 Oct 2008 16:59:18 Link to comment Share on other sites More sharing options...
rj Posted October 1, 2008 Author Share Posted October 1, 2008 It has been removed. And it has vernier cam pulleys which I reckon are lighter than the stock iron items. Still I was a bit surprised that it was that light! Link to comment Share on other sites More sharing options...
Peter T Posted October 1, 2008 Share Posted October 1, 2008 Iv'e heard that you can lose at least another kilo if you drill big holes in the top of the pistons, also some bloke told me that if you remove 8 valves you can make it even lighter. I love the pub talk 😬 Link to comment Share on other sites More sharing options...
rj Posted October 1, 2008 Author Share Posted October 1, 2008 Peter Well... Probably the same as myself removing fingers rather than going on a diet. Maybe you should consider a little weight saving on the feet? Link to comment Share on other sites More sharing options...
Roger Ford Posted October 1, 2008 Share Posted October 1, 2008 Oil's heavy. Leave it out (or use lightweight gear oil 😬) Link to comment Share on other sites More sharing options...
I.Mupferit Posted October 2, 2008 Share Posted October 2, 2008 Another benefit of leaving the oil out is that at a stroke you have upgraded to a dry sump with no further monetary outlay. Brent (aka Arfur Nayo) Link to comment Share on other sites More sharing options...
Jason Plato Posted October 2, 2008 Share Posted October 2, 2008 complete engine on dry sump with throttle bodies, flywheel, clutch etc all ready to install was 82kg alternator and starter = 7.5Kg combined = 89.5 kg obviously the wet sump engine will be lighter without the dry sump gear. here is C7 TOP Taffia rear gunner Edited by - Dave Jackson on 2 Oct 2008 10:08:22 Link to comment Share on other sites More sharing options...
rj Posted October 2, 2008 Author Share Posted October 2, 2008 Dave, Too many HTTPs in your first linkThis will work Just the scavenge pump bracket and tensioner will add 2kg, so obviously the dry sumped is a lot heavier than the wet. A nice magnesium R500 sump pan will help though... I'm also on the drawing board to have made custom brackets for the pump and at the same time being an engine mount to save the heavy 5mm iron anchor as used in the standard installation - I'll also be aiming for a toothed belt like in the Pace installation. - And try to get rid of the nasty hose from the sumpt to the pump 😔 Lots of things to do when preparing a new engine.
