Z320 Posted June 26, 2023 Author Report Share Posted June 26, 2023 (edited) That sounds enjoyable! I remember my 230 SLK with not switched SC (because of an electric fault) was like sleeping aid.. Edited June 26, 2023 by Z320 Quote Link to post Share on other sites
Peter Cobbold Posted June 26, 2023 Report Share Posted June 26, 2023 I get 6-7psi at 2800rpm, rising from 1psi at 1000 rpm. Not the Moss kit but an old Wade RO34 from 1950-60s twostroke commercial diesel (Commer TS3 ). The 6 feels as if it has had a couple of extra cylinders grafted on, similar to a friend's MGBGTV8. I had planned to fit water injection so It would run on 95RON without retarding the spark, but did not get beyond the design stage. Peter Quote Link to post Share on other sites

Only issue is pre ignition. So I run 4psi which is still pretty fun. HI TIm sounds interesting looked a good kit all the parts etc from Moss dont know why they discontinued it david Quote Link to post Share on other sites

A HS8 SU would do the job, and is simple to DIY tune. Fabricating the manifold is tricky, but if Moss still have them in a warehouse somewhere thay could be put to good DIY use.

If so, will it be at the IWE this year ? Cheers. Quote Link to post Share on other sites

Cheers. Hi Tom, Sadly its stuck in the garage waiting for grandson to finish fitting the new clutch. My Parkinson's has weakened my muscles such that crawling around under the TR is impossible. So although I know how it could be greatly improved, the plans for water injection etc are on hold..... Fortunately I am engrossed in new science that I never, ever, thought I would get involved with. See the '90 minutes' thread. Peter Quote Link to post Share on other sites

It is just It has to be drilled so the manifold vacuum can be ported to the power valve of the carb. This is a mod many US tuning know how to do but suspect the setup was not making moss enough to justify getting this done en bulk. Tim Quote Link to post Share on other sites

dblenk Posted July 15, 2023 Report Share Posted July 15, 2023 (edited) Is the M62 eaton supercharger the only one that goes with a TR see a merc SLK unit but doesnt say what charger Jag M112 are there for 4.2 V8's would they work ????

M62's seem hard to get thanks David David, There is some info here: https://www.benzworld.org/threads/eaton-m62-confusion.1431384/ The M62 is ideally matched to a 2.5L engine ** . The M45 will work but has to be driven faster to get the same boost and that impairs the temperature and hence 'adiabatic efficiency'. Compressor maps are in this thread: http://www.vx220.org.uk/forums/topic/138860-eaton-sced-clutch-control-trigger/ The 112 is much longer and may be tricky to fit especially on rhd TR6. Peter ** explanation here: https://supertrarged.wordpress.com/2014/12/16/eaton-m62-blower-calculations-for-tr6/ the contours on these maps represent adiabatic efficiency and you want that to be as high as possible.

Z320 Posted July 22, 2023 Author Report Share Posted July 22, 2023 Hi, today I fixed the tubes in the correct position with the 3rd flange WIG tacked it from behind and weldet all around (sorry, no photo) silver-brazed it and cleaned it lining up of all 4 tubes is OK, better than by welding Quote Link to post Share on other sites

Compressing any gas always, even with 100% adiabatic efficiency, always heats the gas (Boyle's law). The rest of the book is excellent. Quote Link to post Share on other sites
Z320 Posted September 3, 2023 Author Report Share Posted September 3, 2023 Hi, this project is a very slowly growing plant.... With a very simple tool, a level app for my Iphone and manual with files I made all 4 tubes in one line and 20° angled. Only the tube of cylinder #2 is a bit twisted.....this will not matter much. While waiting for sheet steel and the steel tube 80/60 mm I gave some thoughts on a front stay to base the forces from the belt to the engine. My wooden model served me very well for this, all looks nice and easy (I hope). Yesterday I got a piece of aluminium d=100 x 85 mm from the scap yard for a symbolic 1 Euro, this could be a nice pulley. Somehow I'm currently scared about the welding job that has to be done - considering my poor welding talent.... I cold give it alway to a workshop - but will it be any longer a DIY project then?
