Jaguar E Type Series III, 1972

Ok, got it. Thanks.

 

The car is at my house now. I will be putting it in the ad section next week. Here are a few pics.

Did not think that I was a Jaguar guy......spectacular car to drive the few short miles I did to my house.

Your car is beautiful. I have a number of vintage Ferraris and Maseratis and a v-12 etype OTS. It is a joy to drive.
There were 2 different compression ratio cars. The European was 9:1 and the USA 7.8:1.
If you look at the engine number on the ID plate at the front fire wall ( drivers side ).it will end with either LA(LB) or SA(SB). The LA is the 7.8:1 and the SA is the 9:1 engine.
There is quite a horsepower difference between them. The USA cars had 291 and the Euro version 335.
Enjoy your car, I have had mine since 1983 and it has been trouble free.

 

Thank you for the information and your kind comments.

I thought that the USA cars had 272 hp, but nice to know it is more.

Unfortunately, I will be selling the car as I am only the custodian for that period of time until sold.

EHHH!
only the 71 with the higher Comp ratio, had an upward HP..
I believe the american version 72 and above was even less than 272..
actually the series 2 6 cyl had a little more than the 12..

just my memory serving me

 

These Jags have the most legroom. Much more comfortable than earlier years if you are over six feet and have long legs.

 

First I've heard of this. Euro V12 in the E Type made between 265 and 276 BHP from memory and nowhere near 335BHP.

 

google e-type brochures. 315 hp per manufacturer brochure. that was gross hp. then there was a rating change re how hp was determined. that resulted in misinformation.

Interesting horsepower discrepancies, but if someone wants, what I believe, a no nonsense perfect 1972 series III, 4 spd, roadster you won't find one better than this example.

 

Your memory is serving you "Bad Information"....series II 6 cylinder engines were "around" 250hp....1972 Series III 12 cylinder were around "300".....those are facts!!!....not memory!!!.....Mark

 

In the end, Jaguar themselves admitted that the most powerful version of the XK-engine was the EFI installed in the Euro- Series III XJ's: It had the biggest valves and best profiled cams.
Any version of the 12 had more power.

After all the BS HP-numbers that were put in print in the sixties, the early seventies saw at least European manufacturers adhering to the DIN (Deutsche Industrie Norm), and real figures became the norm.

 

I challenge you on this..
My " Bad information " is your poor Knowledge of the Marque, Those are not the facts
The American V 12Cars had a few less HP than the 3 carb 6 cylinders series 2 / 1.5 or 1

Only the late 71 V 12's came with a higher comp. ratio, hence a little more HP..and a little more Torque.
300HP was never a post 1971 USA smog regulated car

61-67 etypes had 265 hp(triple su carbs)
68-71 etypes 245 hp(twin strombergs)

Hello Micheal; I very familiar with the marque as I have owned a pristine 1969 XKE Series II FHC for quite some time, I also own a few other cars & I believe I have a fairly firm grasp on the "feel of horsepower". It has been quite well documented that horsepower ratings of Bristish cars were quite embelished in the 60's. I bet NO Series "I", "I-1/2", "II" Jaguar EVER left the factory with 265hp, a DYNO makes a "liar" out of most Bristish car manufactors in the 60's. According to my link, it states 314 HP for the Series III.....Mark

The E-type's engine was the same 3,781 cc (231 cu. in.) six introduced on the final XK150s, with three S.U. HS8 carburetors and a rather optimistic 265 hp (198 kW) gross rating. (Various sources suggest net ratings between 180 and 228 hp (134 and 167 kW), a point obfuscated by the fact that many of the cars Jaguar released to the press had noticeably more power than the standard tune.) To this engine was linked, sadly, the XK's familiar and cumbersome Moss four-speed gearbox, still lacking a synchronized low gear and no more pleasant to use than it had been on earlier Jaguars.

 

In the past 20 years I have owned 7 E types as well..
I never stopped following the Marque.

314 is surely a mis quote..
if there were 4 webers Then Yes, but I too have had the pleasure of seat of the pants feel driving all series.

I believe a series one 4.2 would take every engine performance award away from the series 3, as the response time and HP were certainly greater.
I believe....according to Victory by design...they went to a 12 to just stay abreast of the decresing HP that the series 2 was experiencing...
Either way...maybe someone more Knowledgeable than us could answer the HP question..

Any DYNO VIDEOS out there.

 

Michael,
Jaguars own brochure for USA v12 etypes states 314 hp.
Google " jaguar etype brochures". A lot of info there.

http://www.jag-lovers.org/brochures/xke3/s3_3-71_rear_l.jpg

This brochure states 314 BHP Gross @ 6200 rpm and 272 bhp DIN @ 5850

Denis Jenkinson's "Jaguar E-Type" book states 314 bhp (SAE) @ 6200 rpm on page 128

Paul Skilleter's "The Jaguar E-Type" states 272bhp @ 5850 rpm on page 119.

Chris Harvey's "E-Type: End of an Era" states 272bhp (NET) @ 5850 rpm for the SIII V12 and 272bhp (DIN) @ 5850 rpm for the SIII V-12 2+2 on page 218.

Philip Porter's "Jaguar: History of a Classic Marque" lists max power as 272bhp on page 168. No mention of gross or net, SAE or DIN, or rpm.

It's probably fair to say that all of them are optimistic.

 

Hello f1_nix; Your various HP stats would PROVE my claim that the Series I-II 6 cylinder NEVER had more HP than the V-12....I rest my case.....Mark

 

From most of the same sources the SI had 265bhp and the SII had 171bhp as published. Not sure of the calculation methods. What the SI and II cars had over the SIII cars was less weight and better balance.

 

The 4.2 with the twin Strombergs was a bit of a joke; Euro-versions still emplyed the triple SU's and were a lot faster.

Even with the extra weight, the 12 was a great car, especially with a manual box. With some handywork, the Strombergs can be replaced by SU's, which makes it more responsive.

 

5.3 Litre

The 5.3-litre (5,343 cc) version had an oversquare 90 mm (3.5 in) bore and 70 mm (2.8 in) stroke. It produced 210 kW (282 hp), (242 hp (180 kW) to 295 hp (220 kW) depending on emission controls and compression ratio) and 400 N·m (300 lbf·ft) in fuel-injected form. Right from the start of production in 1971 for the Series 3 E-Type, the V12 engine had Lucas OPUS electronic ignition. This system was used until 1982 when the Lucas CEI system was introduced. Initially the OPUS ignition amplifier unit was secured directly to the engine between the cylinder heads and had problems due to overheating. Later cars had the ignition amplifier moved away from the engine where it could get air flow for cooling. Originally the V12 was supposed to get an advanced Fuel Injection system under development by AE Brico but this plan was cancelled at a late stage, possibly due to concerns that the design was too similar to Bosch products. The V12 as used in the Series 3 E-Types, Series 1 XJ12 and early Series 2 XJ12s (1973-April 1975) had four Zenith-Stromberg side draft carburettors. After April 1975, the V12 engine used in the S2 XJ12 and the new XJ-S had a Lucas fuel injection system which was based around the Bosch D-Jetronic system

If you rest your case now...you've lost..
We Were always talking about the American post 72 cars here!
242 is the # I recollect, Thats 20 less than the series 1..Heres my confirmation
Wikipedia has it right for American equipped Smog Cars
Case Closed.

I have no dog in this fight. I was simply passing on information from published sources other than Jaguar Cars Ltd. (B-L) literature, none of which make any reference to US market, home market, compression ratios, emission controls, etc. Makes no difference to me which version has more horsepower; I'm perfectly happy with my SI FHC.

 

Ok so it looks like I have interest from a buyer from Japan.

Does anyone have experience shipping to Asia?

I hear, however, that xke's are tough to get into Japan. Can anyone confirm this too?

Thanks.
