Just to add some ’meat to the bone’ Dave Baker has added some very useful pages to his website regarding exhaust;
In fact, even if you are slightly interested in engine tuning you should really put some time aside to read the rest of his website http://www.pumaracing.co.uk/index.htm
To conclude, the smaller primary pipes have made a difference, but the difference was improved further by using the 90mm trumpets. Here is a final graph with the new exhaust manifold comparing the 40mm and 90mm trumpets.
I think with the ultra big valve head and wilder cam a different manifold may be needed altogether. I have since learned about…[Läs mer]
OK, so much for the short trumpets, Andrew at the dyno was in no rush to go home and he seemed as interested as me to see what the 90mm trumpets would produce, 5 minutes later the longer trumpets fitted and we’re ready for another run.
Comparing this run with a previous run, with the old manifold and 90mm trumpets, peak power was up by a tad over…[Läs mer]
The MSS manifold fitted to the car during all of this tuning has been an unknown quantity to some degree, after talking with Dave Baker (Puma Race Engines) i decided to carry out some alterations, primary and secondary pipes were both 44mm od, it was easier to alter the primary pipes, so these have been reduced to 39mm od.
The first run on the…[Läs mer]
Most manufacturers appear to supply shocks for the later type EMS, but the rear early double pin shock is not so easy, i had Bilstein UK manufacture for me a pair of early rears for my ’76 EMS at around £100 each, i don’t think that it is too expensive, compared to my triple adjustable coilover units for my AX at around £500 each! I suppose it’s a…[Läs mer]
With the onset of warmer weather i decided to get the EMS some fresh paint, an old friend is doing the bodywork/paint at his bodyshop, water based paint topped off with glossy scratch resistant two-pack lacquer. The bodywork on the EMS is in really good condition, the paint is a little bit tired and one of the doors is the wrong colour from a…[Läs mer]

The engines are basically the same with regards to internal components, the exhaust valves for the injection engine will be Sodium filled.
Of course the settings for fuel and spark will be different for both engines.
For general information, the later H engine, 1987- i think ?, will have the smaller/lighter starter motor under the inlet manifold…[Läs mer]
I must add, i have had no experience of the Castrol saf oils, so i am not endorsing them.
However, with my experience from rebuilding many stroker/V4 rally gearboxes, on hard tarmac historic night rallies, not regularity, the boxes fair much better with Amsoil and have also resulted in less failures and rebuilds. A quality synthetic oil in these…[Läs mer]
Which Castrol saf-x are you recommending there are two, i think in this case it would be good to be exact.
Castrol saf-xo for gearboxes without LSD.
Castrol saf-xj for gearboxes with LSD.
I use Amsoil in both my LSD and ordinary gearboxes. I have not experienced any clutch chatter/judder from the plate LSD with the oil, but if it does occur an additive is available from Amsoil.
This is an interesting article, maybe some of your favourite gear oils are included 😉
That’s good, now everyone will know 😉
I have a few sets of EMS rims that i want to try this on, but my lathe/mill at home is too small, so i will have to find a quite moment at where i work to try this out.
