Is my X308 XJR slow?

[paulnov21]

Although my 2001 XJR (80k) is a lot quicker than all my other old cars, I was expecting a lot more from the 370 bhp. Once motoring over 60 it pulls great, its just getting there. It seems sluggish even in sport mode, is this normal?
I would like to take it to an expert, i'm reluctant to go to a main dealer, a specialist would be great. Can anyone recommend someone who won't rip me off. I'm in the south of the country i don't mind travelling.

cheers

Don't forget you are trying to move two Ton of car

If in the south I can recommend TLJaguar post code RG40 4TS phone [phone]


Top man when it come to Jags

Try turning traction control off in sports mode, you should get a load of slip when you boot it, if not then something is up.

You need to clean or replace your MAF.

Then you will have your rocket-ship.

Forget that two-ton bks above.

Under six seconds to sixty should feel fast. I have had people screaming in the car up to sixty . No reason your car should not

I would recommend the Surrey Jag Centre in Croydon, if you're looking for a specialist in the South East.

Its all relative but mine still scares me in second flat out sometimes (probably shouldnt do it in a country lane)

Anyway, I would recommend checking the MAF i think i cleaned mine with carb cleaner.
You can buy a U308 OBD code reader for £20 that will show you any MAF fault readings (ebay).
Then I would always recommend getting a pulley upgrade (from £150-300) which makes a big difference by spinning the supercharger earlier down the rev range, feels alot more pokey from standstill.

Have fun

There is only one thing for it... What 0 to 60 are you getting?

I swear my 2002 XJR does 60 in just over 5 secs.

thanks guys
i've ordered some MAF cleaner off ebay and will see what happens. if no change i'll call one of the recommended specialists

I drove a few when I was looking, some of them where definitely down on power. As you say, they just didn't pull at low revs, as if the ignition timing or cam timing was out. Mine would flash the TC light on dry tarmac until it changed into 3rd (or whatever gear it goes to a bit above 60mph).
