Re: Roll over protection

For effective roll over protection have a look at Bob Tulius' car for mounting points. It's in the Gaydon museum.

I'm presuming you're referring to the information in Appendix 7 The production torsion bar figure of 100lb/in" is given in the document headed "Comparative Specification of Production "E" Type and Coomes "E" Type 18th. August 1962 " in Appendix 9. 0.750" nominal diameter, 36 7/8" length - V12 cars ...

Re: That Torsion Bar Question Again?

Hi Damian, Prior to introduction of the larger diameter (0.780-0.784") torsion bars referred to above, production bars were rated at 100lb/in. The wishbone rubbers contributing a further 16lb/in. (info from Jaguar documents dated 1962). Bob PS Have you seen CliveR's posts on jag-lovers? Sounds like ...

Just to add that the S3 PM shows 3off BD25659 each for attaching "Jaguar"and "E Type" and 3off BD25644 for "V12". Jaguar called both "Friction Bush, securing emblem".

Re: Rain shield orientation

Post #1 might there be a sensible explanation for this? No, but not a new mistake. This label was in use in the US in the early days of the V12. https://i.postimg.cc/Wp0yP74J/S3-Rainshield-Sticker.jpg In mid 1972 Jaguar changed the early 2 hole rainshield to a 4 hole type and added a forward suppor...

Re: muffled performance

Norman Dewis doing max speed runs in Italy in July 1970 and chasing the magic 150mph, noticing that only the centre two outlets of the four were effective, had the rear silencer and fantail removed and replaced with two straight through pipes. He reported a 3mph improvement in top speed.

Re: muffled performance

Hi Colin,
Would be interesting to know what brand that silencer is as the position of the welds on this original box appear to suggest a different internal construction on the inlet side.

Possibly legacy holes in the shell prior to a larger heat shield being added during develop...
