guy who goes to our local has a supercharged jag xkr, recons its been chipped and has a smaller pulley on the s/c and is now making 630bhp...

also recons he can do the 1/4 at shakespear chounty raceway in 12. something seconds.... on road tyres std pressure, otherwise std car etc

is that him talking bollocks or perfectly possible?

im seeing him again in about 10mins lol

 

I should hope it does run 12's ! Their not a slow car with 400+hp in standard form

 

cool, was just wondering if he was talking out of his arse with 600+bhp!

 

lololol my 300hp FWD fiesta run a 12.6 i would think a 630hp RWD jag should be quicker than a 12 imo

 

With 630bhp I would want a low 11sec 1/4 even in RWD, what did Lee catermole manage with less than that? I know Lee had a decent setup and very good at launching too but still

 

its an auto, he says if you just stamp on the gas it just lights them up, i dont think hes been propperly dragging it, just had a go one day.

says you need to give it about half throttle to get it to move, then stamp on it and it grips.

i know fa about jags so was just asking the question

 

lololol but the automatic Jag weighs a good few hundred kilos more than the Fiesta lololol.

The book speeds are:

2000 Jaguar XKR 0-60 mph 4.9 Quarter mile 13.3
2000 Jaguar XKR Convertible 0-60 mph 5.2 Quarter mile 13.5
2001 Jaguar XKR Silverstone 0-60 mph 4.8 Quarter Mile 13.0
2003 Jaguar XKR Convertible 0-60 mph 5.2 Quarter mile 13.8
2003 Jaguar XKR 0-60 mph 5.1 Quarter Mile 13.4
2006 Jaguar XK 0-60 mph 5.9 Quarter mile 14.5
2007 Jaguar XK Convertible 0-60 mph 5.6 Quarter mile 14.2
2007 Jaguar XKR 0-60 mph 4.4 Quarter mile 12.8

So with 600+bhp it's perfectly plausible.

 

You can buy a Paramount XKR new with 500bhp their top kit is the Paramount 600 & to get that we are talking many thousands to achieve. have a friend who had their 500 kit from new, its a big old lump & was not as fast as you would think he sold it to buy a BMW.

 

still dubble the power and rwd with less lag

en as said by dan most of the times hes quoted are in the 13's so dubbling the power should knock more than 1 sec off the times better than a 12.6 would you not say?

 

If he had doubled the power then possibly... but 630bhp isn't doubling the power.

....and I'm not convinced that a basic chip and pulley upgrade would produce that much extra power. Also it gets harder and harder to knock time off the 1/4 mile time the faster you go, so going from a 16.5 to a 15.5 isn't too difficult, but going from a 13.5 to a 12.5 is a bit more tricky.

lololol

i dont know much about jags but wouldnt it need much more than a chip and a smaller pulley to make 630bhp?

 

Thats nothing, he is talking pub talk, my fiesta's running 10s

 

well im at 300 so 630 is dubble my power

so hes dubble my wight and dubble my power with less lag and rwd

so at a VERY rough gess he should do better than a 12.6 lololol

ta
clarke

 

 

so double the weight and double the power will still work out the same power to weight and how many times have you tried??

 

Was at shakey last year for a rwyb and there was a jag meet there, there were some running very impressive times and sure there was one in the 12's.

 

with rwd and less lag as said a very open gess

 

lol

he didnt say much about the jag this week, but wants me to service his merc sl 3.2 na - twin spark.

how much of a cunt is it to replace 12 sparkplugs lol?

 

it takes a wile lol the back ones are a bit harder

 

probably a proper twat of a job tbh

 

lads. shakespeares times aint accurate. santa pod times are more accurate. any car that makes say 14s at santa pod does 13s at shakespeare. this is because if you be careful and notice the track shakespeare is flat. where as santa pod is SLIGHT uphill..

 

What were your times at both tracks?

 

Well to me then that makes Santa Pod less accurate as now it's a hill climb track.

Shakespeare is not 1sec faster. I tend to run upto 0.3s faster there, but there could be many reasons as I've never run both tracks the same day.

 

Funny Ive run consistent times at both venues, and times also matched by my GPS/Accelerometer device.

I'd say the above is a bit of a BS statement.
