Jaguar XJS V12 with Injection pb

[nuclhead]

damn thats a nice sound :D

[3084me]

Neat vid. Hey TAB685, I can also confirm that my 1990 XJ-S V-12 DOES NOT force a shift at 5000 RPM. I've owned it since brand new and if it's kept in any gear other than D, It will continue to redline.

Idonlikeveg, I'm not sure about other years though. Maybe cars after the trans case change in the mid 90's or maybe with the 3.6liter & 4.0 liter cars?? My last XJ-S V-12 - 1987 (sold in 2007) - Can't remember exactly but - don't believe that car forced a shift either.

[idonlikeveg]

@3084me I know Jaguar changed the governor weights in the mid 80's. And for my box (1977) you can buy shift kits in order to increase the maximum rpm before a forced shift - because the stock shift was so low and doesn't allow you to reach maximum BHP which is at 5300.

i'm bored of this now! Think i'mma fix the brakes on mine and drive it up the road in 1 and see what happens! :D

the 3.6 has a 4 speed ZF box in it iirc, I don't know about the 4.0 I've never been in one!

[idonlikeveg]

I dont know how you did that, because the governor in a GM400 forces a shift up at 5000 rpm.

Shift seems shakey too. as if wheels were off ground.

also, the first start, you turned the ignition off, the engine didnt stall at all.

Personally i think this vid is a load of pish.

[TAB685]

stupid dumb fucking arsehole ( sorry for the bad language )

1st

The first time i tried to start, It didn't start in normal time

So as i mostly drive diesel my first reaction was to pre heat again, but this is a petrol so no need, just needed to insist

2nd

I passed the gears with the manual shift ( i Choose 1-2-3) and even if I didn't it's still shifts at 5500+ ( this isn't an american V8 )

3rd

The Jaguar rev counters are not good, this one tends to work like old weight machines

[TAB685]

What kind of arsehole are you?

Are you trying to say I faked the fact my Jag goes like a V12 jag goes?

Are you one of those thick arseholes who says " FAKE" on every video ?

[idonlikeveg]

Why would I say you faked how fast it goes? I have one(all be it not road legal at the moment), I know what an XJS is capable of.

And, if i said "FAKE" on every video, Why havent i said "FAKE" on this one?

Stop being so defensive, You can't say things like that based on assumptioms. example: I'm not American, Which you implied i was with "isn't an american V8"

[idonlikeveg]

I didn't say it was an American V8?? (I dont like American engines)

GM400 forces a shift at any selector position (1, 2 or D) not 1,2 and 3! lol get it right!

It's 5000-ish rpm unless the governor settings have been changed. (I can give you links to several sites)

Tachos in the XJS tend to be accurate to some extent. Test it with a signal generator if you like.

When i said vid was a load of pish, I was referring to the quality.

Oh, and the Diesel thing is a poor excuse, I have a diesel car xD

[TAB685]

@idonlikeveg

What your point ?

If you leave it in 1ST and accelerate till the pistons are hitting the valves it won't shift!

XJS tachos are accurate when they work, my doesn't..

What your point? What do you think I did ?

I said amercian V8 because this box was fitted to lots of american V8's duhhhh

[idonlikeveg]

Lol ok i'll give you that one (when the tachos work)

But my point was that the GM400 in an XJ-S forces a shift at 5000rpm no matter what the selector position.

Unless the governor has been modified.

I know that your tacho doesn't work now, but I thought I'd just mention that should you get a working one.

Is this an H.E or a flathead?

[TAB685]

@idonlikeveg

It's a V12 H.E 1991

It needs more than the speedo before it's perfect

I confirm that nothing force the shift, on my box anyway

[jaguarxjrs15]

My XJRS GM400 does not shift up at 5,000rpm, 5,000 rpm is a diesels red line. GM400 shifts up at 6,000. And even when held in 1st gear on the gear lever, it still shifts to 2nd when it redlines.

[idonlikeveg]

That's because the GM400 in the XJR-S has different shift characteristics.

Also, in the mid 80's, Jaguar recalibrated the GM400 for improved response. And during 1992 Jaguar changed the housing of the GM400. I assumed the XJS in this video had an early type because it's says in the description it's a 5.3.

Since my XJ-S has an early type GM400, it's shift point is 5000rpm.

[cetieel]

He has fuck all petrol in that tank!!!!

[humdidoadi]

very cool sound!! :O

[TheMwhaha]

Manualna lepsza idzie poszalec więcej ;)

[remiszewski2007]

siema hej a to jest automat ? bo ja to mam automat i tesz zapierdala

[jagxjsyellow]

:) not to bad - look my jagxjsyellow

[B4CKD00RU5ER]

vy ste blbýýýýýýýýýýýýýý

[remiszewski2007]

I have an 84 and an 89 xjs v12 thest things are Nice, the electronics are tricky but the engine runs mint if you take care of it properly, 1st gear runs to exactly 75mph if times right 2 will go to 120 and drive.. well its been maxed out at around 159

[Explosion000]

Damn I wish they were'nt so unreliable! I want one so bad!

[jetlag700]

Damn, you should buy one, I have two Jags that I drive daily and I love them, they are reliable but are temperamental sometimes, can "pout" in cold weather starts though. I have an 87 Jag XJ6 and an 88 Jag XJS and they are a dream machine to drive, I find excuses to leave the house just to drive my cars. Youl will fall in love with them and never want to own a different kind of car. Donna

[anttheplayer]

soo nice that V12make more vids! i thought 1991's had the 4Ltr instead of the V12?

[TuffNuts]

Damn that thing sounds nice. I was gonna get a 12 but I settled for a 87 XJ6.

[jetlag700]

the Inline 6 cylinder has lots of power, it is only 1.1 Litres smaller than the V12, they are a bullet proof engine, I have one in my 87 XJ6. Just keep your eye out for white smoke coming out the exhaust and rough running, they like to blow a head gasket about every 100,000 miles, mine did and I have read the same from others who owned the XJ6. They really are lovely cars, I am keeping mine and restoring both my XJS which I drive everyday and the XJ6 which is in storage right now.

[cardiffchris]

first is good for 55 or so

so second gear to redline should be just over 100

[anttheplayer]

lovely cant wait to get one!

[hsvdreamnofone]

man that jag sounds so good it gave me goosbumps

[zakris]

Very very nice noise! :D

[TAB685]

Hi ,

The warning light is to say one of the outside lightbulbs has gone , nothing serious ! more videos to come !

It's From 1991

[alltelwarrior12]

Typical XJS with at least one warning light on.

[Scourge151]

Sweet man, can't wait till I've got the money for a K&W converted 6.0 :)

[darkarrow88]

what mufflers do you use, i like the sound and my jag needs more growl
