The car was quick in it's day. Kind of like now a stock Mustang GT (2012)
has more horsepower then say, an 86 Ferrari 308 GTS. There's always
something new and improved out there as the years go by. Even though a
Mustang could outrun a classic Ferrari, I think most people would want the
Ferrari knowing that they have something few others do. That's the way it
is with all cars like Jags, Lambo's, Ferrari's, and so on. You buy it
because it's less common and fun to have!
@w1ngsfly well, this was the first drive after he installed it. so im sure
he wanted to baby it and work out any bugs. these cars arent fast anyways
so a flat out video would only be interesting to XJS performance
enthusiasts.
These engines are capable of being stretched to 10litres for a powerboat or
aeroplane. 6.8 or 7.3 l for a fast road/race car. 570-600bhp is possible,
and with class,style,history and prestige.
Tks for the compliments. Catalysers and intermediate mufflers are history.
Only left original rear mufflers. Nice sound, not excessive noise. It is a
Keisler kit with a Tremec box. Rgds.
Well done !... and no, you don't have to run it to death, to enjoy that
first stick ride ! I own a 77 XJ12C. It will be receiving a 5 speed manual
conversion this winter.
Who told you it was flat out? It was just minutes after starting the car
for the first time with the new transmission!!! Filmed because of sheer
pleasure of shifting.
This system sounds different from the U.S. models(1995-1997) and also your
XJ6. The 1998-2003 X308s had a higher pitch chirp as my dad's 2001 Vanden
Plas Supercharged alarm system differs from the X300's and resembles the
1998-2000 X308 alarm chirp(we had a 2000 Vanden Plas for a few months in
2000). All of them were made by Triplex I think.
+Evan Finch The dropped valve seats require the owner to neglect the cooling system to the point of it causing overheating and then continuing to ignore the issue, driving around with the needle pegged until it overheats enough to cause a separation in the seat and head. Does that sound like a design issue or a shitty owner?The marelli ignition issues only run the years you noted, and they dropped it. Does this sound like an engineering problem on Jaguars end....or the italian company Marelli?The fuel injector hoses get brittle and cause fires if you completely neglect them. Any car that is 30 years old should have its hoses replaced. Once again, if this problem crops up, it is owner neglect, not poor engineering. Any old car can have fuel hoses rot out and cause a fire.While you highlighted some of the most common issues, overheating, the marelli ignition issues, and a few fires from old hoses, any research would tell you that they are completely avoidable problems that are, firstly, not Jaguar design problems, and secondly, don't even fit in the cliche or stereotypical problems people assume they have. They are most specific issues just like any car has. You can assume Jettas are reliable and then google a year and find they "all have water pump failures" or something along those lines. What I mean is, every car has issues, and hopefully you can see by the specifics of them that the generic stereotypes are hardly met and the XJS is like any other car. These cars were made for 21 years, there wasn't some catastrophic problem that caused half of them to catch on fire, because that would have caused recalls, but the way you mentioned the injector hoses or ignition makes it sound like you think it is common for them to spontaneously combust. Really, not to cover up and claim any issues don't exist, it's just the main issues aren't what people make them to be, and when you find out what they actually are, well they are kind of bs. Like I said, 30 year old injector hoses can't be trusted on any car, overheating isn't good for any car, and an outlier of a different company making a troublesome ignition system for a few years is unrelated to the overall design, not to mention nearly noone is aware of marelli. They just spit out the generic "uhh lucas electrics" even though most of the car is bosch.Really the biggest thing to do if you are looking at a v12 jag is to make sure the cooling system works, that is the only "issue" I would bother mentioning. Not even because it causes dropped valves, that really isn't a common problem, it's just that overheating is obviously very bad on any engine. Most of the time the problem lays with old thermostats, which close off the bypass and spell trouble when they fail. Once again, thermostats don't last 30 years, hardly Jaguars fault. Any car I have ever had is like this, British, German, American, Japanese. They have all always had a "well you gotta look out for the trans XYZ switch on those" or "Yep those always have sending unit problems." Great example, my brother-in-law came over today and needs his Tahoe instrument cluster fixed. They all have a issue where the solder separates. They all have issues where the sending units go out. He has one, his sister has one, and his dad have one (tahoe, suburban and suburban) and they all have this issue.Cars are cars, I always find it amazing that so many people build reputations through a massive game of phone call when they are all so similar. All cars have issues, all cars have some BS thing that is harder to work on or get to than it should, all cars have that one part that is more expensive than it should be and all cars have some odd designs that are great and some that are idiotic. It is so incredibly stupid to assume you can ignore your camry for 200k miles because it is a toyota, it is also incredibly stupid to regurgitate that one model or brand has "electrical issues" spanning 4 decades because some guy said so one time.
The 5.3L V12 had several problems involving dropped valve seats (which immediately wreck the engine and require a rebuild) if they're run the least bit hot. Another endearing feature was the 90-92 cars' tendency to have catalytic converter fires because the Italian ignition system would temporarily fail on one bank, then start back up after the cat was full of gas. Earlier cars can have engine fires due to the fuel injector hoses getting brittle and leaking due to the heat in the Vee of the engine. ALL of them can have distributor explosions due to how they're arranged.
