I don't think i would do Meth injection on the Jag, the dealer here are very anxious to cancel your warrantee as is, if they catch something like that i assure you they'll do just that. I think the Jag handles itself pretty well as is. In this intense heat, I wouldn't recommend pushing any engine.
I actually got a kit for the Supra but haven't installed it yet, i intend on bringing the vehicle over and am worried about the availability of methanol in Qatar.
Regarding Qatar; I'm actually a Qatari local.. I have my brother and uncle living in the US and i go down there quite frequently for my business and work (i do type-ratings, and training on Boeing C17/C15s military cargo jets - I'm an Aeronautical engineer working for the Qatari Royal Airforce in conjunction with the US base here).
I'm serious come down here for a visit whenever you can and check it out, i'll be glad to take you around - You'll have a lot of fun.
My apologies for hijacking the thread....

LOL, in the US those old toyotas are worth more than the new Lexus if they are in good shape!

The EuroCharged tune is done and the results are in. I will post the Dyno charts later. I have a few questions about the chart results before I post them. The bottom line is an 18.8% increase in rwhp which is very respectful!
Before - The best dyno run on my stock 2010 XKR (510bhp) produced 382 rwhp and 349 of torque.
After - the best dyno run after the tune and pulley install produced 454 rwhp and 408 of torque.
For $1,075 that included the tune, pulley and the two dyno runs - I believe a gain of 72 rwhp is a "best" value win.
Unfortunately, I have not had a chance to take the monster out because its been raining here constantly for two days -
I will post the dyno charts once I've had a little more consulting about the charts and more real world driving comments after this weekend.

This is the tune ETG starts from which has been provided to ETG from Jaguar. Accordingly, your absolute gain over the best manufactures tune is around 10%.
What concerns me most is how the car will handle the extra power. Overall, it appears that you have significantly increased your wheel horse power for around $1,000--not bad.
You should add this to the ETG tuning thread.

The R-S has an uprated torque converter to handle the additional engine output. The XKR was deliberately de-tuned slightly to keep it within the reliability specs of the standard converter. The TCM does provide some form of feedback to the ECU:
So, it is possible for the TCM to tell the ECU to back off, meaning it might limit engine output to ensure the converter is not overloaded. I don't know for sure that it does that, but I did see it implied in an article I read somewhere (sorry, not sure where).
The TCM processes signals from the transmission speed and temperature sensors, the ECM and other vehicle systems. From the received signal inputs and pre-programmed data, the module calculates the correct gear, torque converter clutch setting and optimum pressure settings for gear shift and lock-up clutch control.
The ECM supplies the engine management data over the high speed CAN bus. The TCM requires engine data to efficiently control the transmission operation, for example; flywheel torque, engine speed, accelerator pedal angle, engine temperature. The steering angle sensor and the ABS (anti-lock brake system) module also supply data to the TCM on the high speed CAN bus. The TCM uses data from these systems to suspend gear changes when the vehicle is cornering and/or the ABS module is controlling braking or traction control.
Using the signal inputs and the memorized data, the TCM control program computes the correct gear and torque converter lock-up clutch setting and the optimum pressure settings for gear shift and lock-up clutch control. Special output-side modules (power output stages, current regulator circuits), allow the TCM to control the solenoid valves and pressure regulators and consequently precisely control the hydraulics of the automatic transmission. In addition, the amount and duration of engine interventions are supplied to the engine management by way of the CAN bus. [my emphasis]

Regarding the LCs.. Your inception would be equally true if you keep in mind the options we get on both trucks here. PTO Winches (Gear Driven from the Center Diff), Coolboxes, rear AC, 3rd row seating etc.. All of which were not offered on the USDM LCs. Here however, they are no where near as valuable as the new ones even though they are both one owner, fully documented, factory painted examples.
Regarding the tune, my interests would be the same as DGL; I have difficulty putting the stock power to the ground as is. I would love to tune the Jag but would be worried about how the car would handle the extra power. Transmission would be another issue I feel that its having enough difficulty handling the stock power. I'm sure one could upgrade the valve body and torque converter to handle the extra power. Another problem is, once everything is said and done, i'm pretty sure warrantee would be void!

You just tap into the bottom of the reservoir. Everything else works like normal. The best part about doing it this way is that you get a low washer fluid warning when you are running out of fluid. Not all systems come with a low level warning for a dedicated bottle.
Since the intake air on the Jaguar supercharged engines is already cooled, I would consider a misting system on the intercooler as opposed to injecting the engine. The benefits won't be as substantial, but no warranty issues and that kind of a system is much easier to set up and tune.
If you spray into the intake, you will want to do it after the supercharger. Spraying before the supercharger will cause the coating to wear off the blades over time. There is no harm to the engine from this, but it will cause the supercharger to lose 5-10% of its efficiency. I have seen this first hand and also discussed this at length with Eaton. However, when you spray after the supercharger, the question becomes where do you mount the nozzle to ensure even flow to each cylinder? The only real way to guarantee this is a separate nozzle in each runner - which becomes a real pain.

[QUOTE=maldweik;833145]This seems very interesting for the Supra haha. I never knew you can do that.. Do you still have wiper fluid though or is the whole system routed to the intake?
Still have wiper fluid for the windshield. The mist is VERY fine and at low boost doesn't even come on so its not even like you have to fill it every time you get gas either.

The brand is not important and anything you can get here labelled as windshield wiper fluid will work but most marketed towards "Winter [mix]" has more methanol and is preferred.

After conferring with EuroCharge today on the current dyno results, it was decided that I need to have a new set of rear tires installed so we can get more accurate dyno results. The results I am getting are below expectation. The good news is either way, a meaningful gain was achieved. We just need to be as accurate as possible.
