Right its a supercharged A8 4.2 Quattro Sport, ABZ engine (originally 300hp) it has a 9.0:1 compression ratio and now has an Eaton M112 Supercharger producing around a 1 bar of boost.

As far as power is concerned I dont know yet, I expect it to be in excess of 450hp. It is still a bit of work in progress on that side of things so we will have to wait and see. I am on strictly limited RPM until everything has be honed/checked but I was able to drive the 300 odd mile journey home without incident although at present it has an oil leak so am in the progress of cleaning it down so that I can identify the source.

The work was carried out by JOMO engineering in Ireland but everything is most definitely custom fit, this isnt going to be any sort of kit. As you can see from the pics it has been shoe horned into the space previously occupied by the variable length intake manifold and fits snug under the bonnet. Everything from the complete breather system, throttle butterfly, belt routing, intake manifold. It is such a tight fit that both the sound proofing on the bulk head at the back of the engine and the fan blades at the front of the engine have been modified to accommodate such a large charger

throttlebody, that was the word I was looking for earlier, went with throttle butterfly instead.

Before you get to excited its been a bit traumatic getting this far, in the region of 1000 hours labour over an 18 month period, my general lack of posting over that time is due to me not having the car.

Can't wait for more details. Bolting a charger on is one thing but getting it all to work is another. What ECU are You using, injectors, fuel pressure, fuel pump.

i cant wait to get my hands on something like this, did you use a plate to lower compression or did you change the pistons ??? also wandering as you are running around 14psi have you got an intercooler or charge cooler in mind or set up at the moment and what duty cycle are the injectors running to cope with more air ? also what about the maf did you bypass it and use a map sensor instead ? so many questions i need to ask to get this up and running
