Took the beast out to the track today. Ran two passes at 12.31@117.5 mph. 8 degrees ambient. Car is 100% stock.

Official race weight (car+driver)....4545lbs!

 

Very cool! I'm planning on taking mine out to the strip before the end of the year and I'll post the results. Your times are what I was expecting. Did you leave Trac DSC on or did you disable it completely?

As for the weight, that's one reason I'm interested when the new aluminum version comes out. Could take a half a second off the quarter and add some mph at the end if they drop 500 lbs.

 

Sport + Dynamic only. No burn out. DSC on full. Automatic shifts.
Still spun out of hole.

 

I was shocked at how heavy it really is. 4340 lbs without me and with 5 gal in the tank.
The F type conv that went with me is 3900 without driver.
A 2014 Dodge Challenger was 4150 with driver. ..

 

Nice, not bad for your first runs in that car! I am curious what the F-Type ran (and which engine / trim it was)

 

The results are over on the F type forum. F type is convert with tune and pulley. Ran 12.06 @ 123. Traction was an issue. Very hard charging top end

I did try the same but it cut me off at the start. Did you try with 1/2 DSC off ? The best I did with my modded XFR is 11.736 with 1/2 DSC off, no burn out and with raising the rev.

 

Sorry, without raising the rev.

 

Impressive! What mods? What MPH?

 

119mph. I have attached time slip.


Will take it in another 2 weeks for the main challenge. I haven't done this for 2 years but an owner of 2014 M6 Grandcoupe Competition Pack with Akrapovic Exhaust want to test it against my car so I took it for a warm up a sessions.


Mods:
PP-Performance Software
Arden Full Exhausts
Spires Coilover

 

That's pretty impressive....I wonder what my wife's XF with the non supercharged 5.0 will run.....

 

you guys should post your slips on this thread -- you have some really quick times.

I don't see any XF NA times...

Here is the time slip and weight at the end of the run with me in the car. Official NHRA weight booth

 

I did not realize that the XF was that fat! I could swear that I read somewhere that my XF weighed 4045 lbs.

 

XF? You are correct.
It adds a good 300lbs for the supercharger and RS suspension.
I was within 5 lbs of Jag's stated weight.

 

that is crazy fast!
