Tinweevil Posted January 26, 2015 Share Posted January 26, 2015 Interesting thread.My £0.02, you can save the weight of the expansion bottle, bracket, pipe and contained water by using non aqueous coolant. It doesn't expand with heat. Bonus 1: your system runs with little pressure and requires no additional corrosion inhibitor. Bonus 2: your wallet will be ligher too.

Richard B Posted January 27, 2015 Share Posted January 27, 2015 Quoted from BiTurbo228 Canleys alloy diff casing: 2.673kg Whats the weight saving over the cast iron one?Of course playing devils advocate, the CC alloy diff casing carrys another 1/2 pint of EP75W90 oil and then you have to factor in the weight of the Quaife LSD (well I do anyway) 😎 Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted January 27, 2015 Author Share Posted January 27, 2015 Good point :S but if I can get better heat dispersion and an LSD for no added weight I'll be happy.I haven't pulled the cast iron one off my diff yet, but as soon as I do I'll post the weight I'll also see if I can get the weight of the standard diff gear set to see how much heavier the quaife is...

BiTurbo228 Posted February 12, 2015 Author Share Posted February 12, 2015 Latest weight:Cast iron alternator bracket: 0.586kgCanleys alloy alternator bracket: 0.242kgYou could probably shave some more of that weight off the alloy one to be honest, but I don't know how strong it has to be...

John Bonnett Posted June 25, 2015 Share Posted June 25, 2015 Quoted from Richard B John compare that to the weight of a Hi-Torque starter. Maybe you should change the ringear? I totally agree Richard and will do in due course. I feel a bit vulnerable running such a rare starter motor in addition to the weight penalty.

BiTurbo228 Posted July 6, 2015 Author Share Posted July 6, 2015 Quoted from Bainzy Spitfire Mk4/1500 door glass - 2kg per window (so 4kg a pair).Spitfire 1500 USA door with side impact bar - bare shell with only hinges - 11kg Excellent that'll be useful if I ever want to go to perspex windows or fibreglass doors Oh, just weighed my Dolly Sprint alloys. 5.4kg sans tyre, which is lighter than the Cosmics I have. The spacers you need to run them on a spit will add weight, but what's 15mm of alloy plate? Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted October 13, 2015 Author Share Posted October 13, 2015 Just weighed my lightweight alternator (originally bought from Canleys, but bought off eBay by me) and it came in at 3.118kg.A little heavier than I was expecting, but every little counts Canleys big brake kit is on the way so we'll see about that in a couple of days Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted October 19, 2015 Author Share Posted October 19, 2015 Right, big brake kit arrived so naturally first thing I did was weigh them Canley's 4-pot caliper (whole assembly including pads): 3.118kgDoes anyone know the weight of a standard Spitfire caliper?I've also finished my lower suspension arms and weighed a load of little bits around the rear suspension.Rotoflex radius arm (complete with bushes): 0.904kgRotoflex wishbone inner polybush: 0.044kgRotoflex wishbone outer nylon bush: 0.006kgMy lower tie rod (complete with bushes): 0.664kgMy whole lower tie rod assemble (both sides): 2.661kgSo add everything together and we have in order of weight:Cast iron rotoflex wishbone assembly: 6.788kgAlloy rotoflex wishbone assembly: 3.756kgLower tie rod assembly: 2.661kgPretty pleased with that Quote Link to comment Share on other sites More sharing options...

Don't you want to compare the 4-pot caliper & disc to the (heavier) GT6/Vitesse caliper & disc? Quote Link to comment Share on other sites More sharing options...

That would be useful to know as well. Canleys mark down the GT6 caliper as 4.5kg, but I don't know if that includes pads and I haven't a foggy about discs...The main reason I wanted to know Spitfire ones is so I can work out how much heavier/lighter it'd be on my car.

BiTurbo228 Posted November 8, 2015 Author Share Posted November 8, 2015 Right, whipped one of the Spitfire calipers off my old hubs and they weigh 3.534kg complete with pads.Also weighed a couple of other things.Single-rail non-OD gearbox from a Dolly 1850: 28.4kgCompares to a 3-rail non-OD gearbox: 34.5kgI reckon the alloy bellhousing on the single-rail is something to do with that...Then I did diffs.Standard cast-iron case 3.89 open diff: 23kg3.89 open diff with alloy case: 19.7kg Quote Link to comment Share on other sites More sharing options...

BiTurbo228 Posted November 25, 2015 Author Share Posted November 25, 2015 Brand new goody in the post, so first thing to do (after gawping at it and shaking the moths from my wallet) is weigh it Quaife ATB LSD for a Spitfire/GT6/Marina*/Caterham: 4.515kg*how many Marinas do you think are fitted with helical LSDs...

JohnD Posted November 25, 2015 Share Posted November 25, 2015 BiTurbo,4,5 Kgs? Is that just the LSD unit? Not the whole diff, surely?And you need to compare that weight with the parts it will replace.But congrats on a good choice, I've had one for years and they are incredibly robust, as well as effetcive.John Quote Link to comment Share on other sites More sharing options...

When I pull my diff apart I'll get the weight of an open diff centre.All I hear about them is that they're expensive, but well worth the money.

Even went and got a flat board to put under the scales to make sure it wasn't uneven ground giving a funny reading.All I can think of is either heavier internals on the 3-rail.Either that or the single rail having an alloy bellhousing. Forgot to check on mine, although I'll do that this evening...Quoted from GT6 M And just cos ye got a quaif init, dont mean that it will be OKdiff unit yes, but it will not stop CW, or P loosin their bits.M Agreed. I'll need to put it back together very carefully, and check the condition of the cwp to make sure it's not damaged.On the plus side I've got a 3.89 which from reading around seems to be slightly less fragile than the 3.27, for whatever reason.I've also read something about the earlier diffs having slightly beefier bearings (but weaker carriers, which I'll replace with the Quaife unit). Seems like a recipe for a strong small-chassis diff, unless I've got my facts mixed up... Quote Link to comment Share on other sites More sharing options...
