I've been following some of your threads on the UK audi forums.
I'm interested in rear brake upgrades for the s8, are you using c5 rs6 rear bits?
If so, do you have any details on what your used exactly?

Nice looking car by the way!

On this car is used caliper from phaeton. But is not direct fit, so need to be modified rear hub and new adapters for caliper support-this was need because very bad corrosion on hubs. Normally i design and made new caliper support for direct fit, with stock caliper/FL D2 have big pistons 43mm, and put brake pads from D3/phaetons/rs6 c5 etc.

it is a pity that no one asks anything specific about the project. Apparently not interesting to the audience?

Nakata I would love to hear about the supercharger setup! I have been strongly considering this path, Tweetler performance over here in the states has been developing a pretty exciting kit.

Is that an Auxiliary oil pump located next to power steering and coolant expansion tank?

This pump is water intercooler for supercharger. This car have lots of modifications and not so many space under bonnet for hidding it.

Sweet Ill fire off a couple of questions here.
What applications did the super charger / throttle body / intake come from? or custom?
Looks like the pulleys were all custom made? Would you be willing to share the specifications so they could be replicated?
Any fueling upgrades required to get the power you are currently putting down?

Intake manifold is made by my self, mine desing and etc, TB is stock for engine.
Belt is 8pk, so need custom pulley on everything. Because belt is common with alternator, AC and etc.
For fueling is change only injectors, for this results they are only thing need to be change.

Nakata,

How do you make the idler to replace the fan bearing for the mechanical fan?
What auxiliary fan did you use?
Did you do the tuning or did you have a tuner assist with WinOLS?
I'm sure there are many more questions, but trying to start off slow with them.

Thanks,
-Richard
