Our customer came to us and wanted an extreme build making around 700HP, so we went to work and this what has transpired:
Whipple 2.9 with intercooler, rail, injectors, throttle body plate etc...

700 chp? Jaysus!!! Guess it's safe to say your XJR customer has an "Open Check Book" ($20+k motor)? Is this a 4.0 or 4.2 supercharged build-up? I'm guessing a 4.2 s/c. Not speaking for eveyone...this's an exclusive engine build. Just give me a twin screw for an extra 200 chp for the S-Type R. DANG! That XJR will take out a 560 chp Caddilac V, Bentley Super Sport, and 580 chp 2013 Camaro LTZ. Jaysus! That motor looked too good. Gunna play that Lotto ticket on Saturday.

BIP, what assembly used for LSD? Again, if U R able to do this work on a 4.0 s/c "S", can you develop an adaptor for the 4.2 S-Type R's intake manifold so that the Kenn Bell twin screw adapted to the XKR can be used on the 4.2 STR as well. This was performed by our forum member AVOS for one of his customers in Belgium. Many of us R interested in this mod, an affordable LSD conversion, and an ECU tune to bring it all together.

BFSGross, to answer your question, yes sir we can. We are going to be cutting an intake manifold for our E85 E55 car, so we can install a Whipple 2.9 on it.....
The 2.9 whipple that is going on our customers 4.0 XJR, is actually the second intake we cut, and second Whipple been installed. We originally went with a 2.3 Whipple and specific intake for that size blower, but it was not going to generate enough power, so we sent that unit back to Whipple, and got the 2.9
As a result, a second intake had to be cut for the larger unit.

Hi AVOS. Thank U for chiming in. Is there a difference in mechanics and power potential between the Whipple and Kenn Bell? Will you be developig an STR intake manifold adaptor that'll allow for the customer to provide his own Kenn Bell blower? If yes, what'll be the approx. fee for one or both? B.I.P, not to speak for all; I believe most of us aren't interested in such a radical exhaust mod. Both the cost and increase in noise would likely be unbearable, besides, a very small amount of STR's will see track duty. Looking for a reliable 450+ rwhp STR to hold its own against Caddilac V's, Camaro's, MOPARS, BMW M's....

We all know how the Jag ECU does not like to be tuned or tweaked much, if at all. Once our build is complete, and we start the dyno tuning process of the car, if the ECU does not take to our adjustments, a stand alone system will have to be used.

I'm another owner who is watching this very significant project with great interest.
You are likely aware that no commercial performance aftermarket parts have made any significant performance gains for 2000-2008 Jaguar "R" cars (S Type-R, XJR and XKR). AVOS (a very knowledgeable, nice and competent guy) has an awesome twin-screw power adder but he's across the pond and is a one man band.
Many of us have invested in performance parts with "promised" performance gains -- but no significant results have been realized or proven. In the years of racing my S Type-R (along with 15 dyno pulls) the only significant power increase was due to low temperatures. When the air temperatures are cold (<55F) along with cool engine coolant (<180F), good power is present. Without the use of nitrous oxide and/or low temperatures most of us have only proven performance gains of up to 25 horse power and up to 30 torque by doing the following:
-upper s/c pulley (2.6") = better low rpm performance at expense of high rpm performance
-remove resonator, install high flow cats, x-pipe, and high flow mufflers = slight increase of hp and torque across the board
-low temp stat (or no thermostat) = good performance for longer duration
-remove OEM air intake mufflers, install curved pipe keeping OEM air filter box
