That’s a great achievement with just pulleys and a tune
you will def get to 10.5
either a ported charger or a 2300
watwr meth
fi interchiller
this will ensure rock solid low iat and mat

Thanks! And no need for 2300, plenty of power left from our 1900s, most likely more than our engines and transmissions are capable of handling!

Just started a thread about pully and tune for an SVR.

Looking to still be 100% street and almost daily car as well, how is yours for that type of use? Are the tunes canned or on-site assume only?

At Alpha Jag Tuning we have been tuning 4.2 , 3.0 and 5.0 engines for quite some time and set records before and now this latest record on FType R and with minimal mods..
Definitely properly tuned car will drive with no issues as a daily driver, when you step on it is when you will
notice the extra power and with custom tuning lots of parameters can be fine tuned to your liking.
I have 3 Jaguars that I drive, XKR, XJ SC 5.0 and ftype-R
All tuning that we do is custom and is according to data logging and is easily done remotely with our tools

Default Best time yet 10.7 1/4th

Update:
Took the car to another racing event by Bakersfield CA! Unfortunately heavy fog and 40 degrees weather all day made the track slippery for the AWD cars since we can't do a proper burn out on street tires. Nonetheless even with loosing .15sec on takeoff managed to get best of 10.7 and 131MPH trap so now that's a new record!
Happy with that even those car does have 10.5 in her!
Stay tuned!

Went to a local drag race strip last Friday . It's only a 1/8 mile and density altitude was 2000+ , nonetheless car ran pretty strong! Still full factory exhaust with cats!

What tires are you running (maybe I missed it), and how are you launching to get your 60’ below 1.7?

Impressive numbers. 🤙🏼
