35T AWD 1/4 mile thread

Thanks for setting me straight. I remember reading about a clearance issue on one of the pulleys, I was confused. So its the top pulley the one that's the "Biach" to replace. I too will wait and see other users' results are after thousands of miles on the lower pulley. BTW I did get my programmer from VAP this afternoon, and they are working to get me my mod files tomorrow sometime.

I just weighed my AWD 35T and with 3/4 full tank of fuel it weighs in at 4,040 lbs without me in it. This thing is a tank and is made of aluminum, how is that possible? My XFR weighed much less than this boat. This car won't go 11's without a few more mods or if it sheds some weighed, #FatCat

That is still 3900lbs dry.... I guess those double wishbones are made from lead.
I wonder what is the weight difference between the base model AWD vs fully optioned AWD.

With no options on mine the site says ( From 3,795 lbs) for the AWD R-Sport

The smaller upper pulley was discussed at length by Unhind and VAP when developing the tune for the F-type V6 (same engine as XE, as you know).
The consensus is that there is a very small enhancement from swapping the upper pulley to a smaller one on the V6. For hp/$ you are much better off buying the lower pulley. And its much easier to install to boot.
Personally, I'm shying away from either pulley. The upper one is hell to install (and you have to shave some mm off the SC nose - no thanks), and changing the lower one gives me some concern about vibrations/damping. Superchargers are notorious for generating these kinds of vibrational forces which can be hard on the engine crank if not damped properly. I'm sure JLR has done the math on their crank pulley but not sure how a non-OEM pulley would affect this... just my opinion. I'm gonna wait until we see how engines hold up after running these lower pulleys for ~20k miles and then decide... either way the tune alone is super safe and gives great gains.

Wow! I loaded the VAP tune this morning and WHAT A DIFFERENCE. :-)
I've no other mods. I can't tell you exactly how fast my XE got, suffice it to say the 120MPH speed limiter was nowhere to be found....(Let's assume I was doing this on COTA, which is 15 minutes from me).
I hit 150 and had more power left, but ran out of straight. I was surprised the car stayed planted aerodynamicly at these speeds of 110 to 160ish, although if i was racing id surely add a tail to add downforce on turns.
I did a little parking lot visit, and this XE drifts easily...like a champ. Bye Bye tires. I'd be surprised if the rears last me 10K. But its worth it!
I do plan to see what a 1/4 runs on my RWD, in the next few months. I'll post results, good or bad. Compared to the considerable 340Hp stock, this VAP tune makes the XE turn into a Monster. Highly recommend!

I'm pretty sure you guys are aware of this, but if you were to couple a top pulley with your tune and crank pulley, you'd be approaching 500HP.

I'll probably get one of these before the crank pulley because it is easier to install and relatively inexpensive ( in comparison to the crank pulley from VAP). It should be possible for me to run around 450HP with the small pulley and the VAP tune. The small pulley runs about $370.00 USD, an easier investment for me to to justify for another 24 HP.
And later when I get another $2K I'll get the crank pulley. Then it should push around 500Hp with both.

There's no way a top pulley makes another 24BHP. The V8 Supercharger has a 65mm top pulley, you can get down to 62mm without shaving the supercharger snout. The V6 already has a 62mm upper pulley. So, if you shave the snout and plan on 4-5 hours for the install, you can install a 60.5mm upper pulley which works out at a whopping 0.75lbs of boost.....
I suspect you're right. No way 0.75lb gives 24hp

After the VAP tune and lower pulley, the only other significant way to get better times is to either lose the weight or start looking at Nos or a meth injection kit.
Other than wheels there is little else we can do to reduce the weight. I have looked into a carbon fiber, but there is absolutely nothing out there so every part will be essentially made, almost one-off piece. That easily starts getting prohibitive. I am in the XF so the XE market may be different, but I don't think by much.
The F Types have tons more options...but...I need the four doors still so....wah
