  1. It's not rhe eepeated stress or wera, the idea is that if you take a stock rod bolt out, and replace it with one that can clamp down “tighter”, it will distort the rod slightly and then lead to bearing failure. In order to avoid this, ARP recommends eesizing of the rod after the ARP bolt install.
  2. I would say MS2X isn't worth it with 6 cylinders. http://www.extraefi.co.uk/products/MS2X.html If you want sequential with 6 you'll need MS3X.
  3. A VW VR6 coil pack is an option. https://www.autodoc.nl/hella/9972299
  4. Quite a destruction, John. I can't go into details too much, but at work we regularly run engines past their maximum rpm, but just short of destruction. To this end thermocouples are installed under every bearing shell, even the big ends. Normally the bearing temperature increases linearly with increased load, but past a certain point the load becomes too much and the temperature skyrockets in a fraction of a second. A human wouldn't be able to react fast enough, but the software/control system is quick enough to catch it and prevent major destruction. The key is to remove the load and return the engine to idle asap and keep it running. If you do stop the engine, the bearings will melt to the crankshaft.
  5. Agreed, I found these 2 videos the most helpful:
  6. Got one of these last year, basically like an R-tech but sold under a different name. https://www.ebay.de/itm/TIG-WIG-Schweisgerat-AC-DC-200Di-200-A-Inverter-Schweissgerat-Pulse-HF-MMA/382386913925? I think it's more like soldering than Mig welding. Not tried aluminium yet, though. Oh, one tip, I disliked the standard supplied torch cable very much. So much so I bought a different torch on aliexpress, which has a much thinner, single cable. This improved my welds no end, as it gives much more freedom and precision. It is similar to this one: If you do intend on getting one like this make sure you get it with the right connector and torch. As there are different size connectors.
  7. Thanks for the link to the RUSEFI, looks like a very intering alternative to microsquirt. Congrats the manifold looks great! Don't think the angle will matter, did you take a look at the weber manifolds? "Any reason not to use copper tubing for a fuel rail? " It could crack due to vibrations if it's not well supported. Don't know if you intend to but a Bosch 044 fuel pump, but that's way overkill for an engine only making 119 BHP. Although the one in the link is very cheap for a genuine Bosch 044 pump. I would look to a smaller fuel pump. This one will draw a lot of amps and heat up your fuel. External or internal swirl pot are a necessity with fuel injection unfortunately. EFI pumps don't suck fuel well at all and always have to be mounted below the fuel tank/swirl pot. Swirl pots are necessary because EFI systems don't have a "reserve" like carburetors have with the float bowls. So if the fuel supply is interrupted, due the pick up sucking up air, the mixture will instantly go lean. This can happen when you're you braking, accelerating or cornering, especially when the fuel tank level is low.
  8. Looks like the Belgian Lidl shop also has the die grinder and will allow you to purchase it. Though they don't send it abroad so you will have to have it send to a pick up point in Belgium. https://www.lidl-shop.be/nl-BE/PARKSIDE-Rechte-slijpmachine-PGS-500-A1-500-W/p100312246 +1 for the vacuum cleaner As for gloves, I like nitrile ones as the latex can cause allergies in the long run. I also tried stones on the drill, amazing how fast they wear when you don't spin them fast enough.
  9. You might find this thread more useful: https://www.triumphexp.com/forum/spitfire-and-gt6-forum.8/sectioning-a-mk4-218142-head.934685.934787/ Forgot to add that I did take a mold of both the 6 and 4 cylinder heads; they are very different indeed. And not in a good way for the 4 cylinder, as you can see in the pic.
  10. Hmm, looks like my memory is failing, but then I did copy it around 20 years ago. I did find the copied pages, but it's from a speedpro and not written by Vizard. The amount of detail it goes into is pretty small. Just a few lines of text a flow diagram and two pics. It says to: - remove the valve guides and use ones that are 7⁰ bulleted. - modify the combustion chamber. - cut 3-angled seats. -modify the SSR with a generous radius.
  11. I already had an air compressor so bought an air powered die grinder. Didn't like it as my compressor couldn't keep up and found it wasn't very powerful. Then bought an electric Bosch one 2nd hand, similar to this one: https://www.amazon.co.uk/Bosch-Langhals-Geradschleifer-KickBackStop-10-000-28-000-Regelstufen/dp/B0057CI8T6 Much more powerful, but you have to be careful or it will kick back like others mentioned. Don't know how to explain it, but you have to hold it "loose", but firm and be precise" to avoid the kick. If you don't want to spend that much Lidl has a 500W die grinder for under 20Euro; https://www.lidl.de/de/parkside-geradschleifer-pgs-500-a1-500-watt/p360324 I have copied the 4 cylinder pages out of the Vizard book a long time ago. I'll have a look if I still have them. If you hook the amazon drill extension up to a normal drill, forget it, like Nick just said the speed is much to low.
  12. Funny that, my brother has an MGB and my experience it pretty much the opposite of yours; the MGB doesn't sound half as good as my Spitfire. Anyway I think you have already found the problem, with 80psi on 2 cylinders and 190 on the others it's never going to run very good. Here are 2 examples of how a Triumph 4 cylinder should sound: https://www.youtube.com/watch?v=HhgEjkAla8E https://www.youtube.com/watch?v=B3RRREAn1mE
  13. Here are some more. You've probably all seen these, but I'll post them anyway.
  14. What worked for me in the past was to put it in gear and have someone rotate the output shaft as you wiggle the gearbox onto the engine.
  15. Or: http://efi.ttrignition.com/quadramap.html Also read the following as synchromap is no longer being developed. http://www.msextra.com/forums/viewtopic.php?f=67&t=64579
