Re: rolling road figures

I'd go with those figures Chris. The most powerful XK was the EFI big valve 4.2 with electronic ignition which developed about 220 on a good day. And I do mean literally on a good day, as ambient temp and air pressure need to be corrected for. Since there is no such thing as directly measuring horse...

Re: S3 V12 Stromberg/Dizzy vacuum pipes

US Exceptionalism means you use different octane ratings. Thankfully, there are still 360 degrees in American circles, so at least the timing will be easy.

Someone clever will explain the RON thing and work out the octane equivalency issue for you.

Re: Subtle stripes fitted

That was one of my least favourite corners. They didn't call it the Devil's Elbow for nothing. It looks flatter now but it was a horrible very off-camber sweeper, downhill into a pile of pit-related ironmongery if you got it wrong. The preceding chicane wasn't there then, so you took it faster, but ...

Re: Seals and seals...

Thanks for the help guys. I see there have been quite some changes in how Jaguar sealed the doors and windows. Well they used three different engines and 8 bodies too, so the wrong book could be worse than no book. Nothing substitutes for the right book, which you haven't looked at it seems Thim? I...

Re: Seals and seals...

In fairness to Thim, the 2+2 seals are different from the FHC in some places (hence J38 not J30 book), although he has worked out the biggie with that unique tubular door seal.

Re: One for the Lightweight or Mk IX experts

Thanks Harold. Same as mine (I rounded up a bit). I've ordered a slice of 3.5" pipe with 1/4" wall thickness, so there won't be much machining needed to make up a couple of adapter rings to position the disc. Then I'll rotate it on the flange and drill five fresh fixing holes midway between the exis...

Re: Seals and seals...

Jag paid a graphic artist good money to make sure your J38 2+2 spare parts book shows the place and orientation for each seal by showing its cross section with a kind of magnifier effect. The spares book was, literally, the first thing I bought when I got my first E-Type. A picture being worth a tho...

One for the Lightweight or Mk IX experts

After spending a pretty penny getting a set of MkIX front brakes adapted to mimic long-nose D parts, I was dismayed to find not all five-stud discs are the same. The MkIX holes are on a slightly large pitch circle diameter and the central hole over the hub is 3.5" instead of 3.25". At first I though...

Re: Fixing the Y trim piece on centre console

Hi, Does anybody have a picture of the underside of the Y shaped trim piece on the centre console? It would appear that mine has been modified (shortened) by the PO and it is unclear what is original and what is not. I am trying to establish how it is fixed on to the console. Also is the gauntlet p...

Re: Engine rebuild, various questions, and - hopefully - some good ideas.

One thing I always do to the pick-up pipe is cut a couple of vee notches in the lower end. I’ve measured some that come very close to the base of the sump and given the low pressure in that part of the circuit I am nervous about any restriction to flow. By notching the end it is impossible to blank ...

Re: Prescott Hil

Last time I did a timed run, in 2011, we emerged near the top from the shelter of the trees onto a newly-damp track, courtesy of a passing shower. That was tricky in itself, but the gear lever coming off in my hand was even trickier. The skimpy weld on the Getrag conversion bridge piece came apart a...

Re: Acoustic Cameras

With speed cameras you can link the image to the offender by validation road markings. If you're right behind a noisy vehicle with both in shot, how do they avoid mixing up offenders?

Re: Gearbox Numbers

I had an April (ish) 62 FHC which showed a gearbox number the same as a later car, according to the late Mike Cook, Jaguar archivist. He said my car was a personal export car and there was probably a warranty replacement box fitted after the owner’s initial UK/ Euro mileage. The removed box would th...

Re: Trouble shooting 123 dizzy

360 degrees out (two strokes) not 180 (one stroke, i.e. BDC). Believe nothing, verify everything, starting with the right stroke and timing marks.
