I'm doing similar, but in a B5 A4 quattro, with 4,2L S8 motor from the onset.

What pistons are you running to drop compression in your ABZ?

Ooh, please start a thread with :pics:

Marc is it done yet???

What brand s.s. lines are they? They should not rot out in only a couple years, especially not when used for coolant.

summit. I'm a little ticked.

I avoid Summit AN stuff if at all possible. Some of the AN fittings I've had had sloppy tolerances, and would strip out very easily. All my stuff is Earl's, with a couple Aeroquip pieces thrown in.
If you're going to order a lot of stuff, and can wait a few extra days for shipping compared to Summit, it pays to go here:
www.anplumbing.com
I've probably saved a couple hundred dollars by going there...

Ive bought from AN plumbing before.I just bought some from Summit and I laughed @ the quality...

Earl's fittings or dont bother.

Its an ABH with stock internals, replacing a PT with stock internals. Stacked headgaskets to drop CR.

Show us ya thread on that S8 into .......

so no go on the coupe. got everything all done and leak free (after much f'ing around) and then the car shredded the alternator belt... Thats happened before so its clearly a design issue I need to revisit.. just not something I want to deal with on a multi-hundred mile two week road trip. So the S6 got some love in the form of a new drivers front CV boot, now packing up, gotta head out the door at 7 tomorrow..

Bummer, but probably a good call.

To me it sounds like the only logical solution would be a rear axle mounted alternator.

progress.....

Thanks Siena,

I didnt realize that was your thread, nice work

Mark, what was the prognosis on your welding issue? Catch me on chat.

70 pages, wow.

so I worked on my serpentine tensioner modifications a bit yesterday. Decided I should be able to modify the stock tensioner to do what I want.

here is where I'm at so far:





the basic idea here is that an idler roller gets bolted to where the tensioner shock used to go, and that will press on the back side of the belt that will be going directly between the crank pulley and the alternator. I have removed the giant spring from the back side of the TB cover behind the stock adjuster nut. I then drilled two holes that mark the outer extremes of where the 'slot' needs to be milled that will be used to clamp down the adjuster once it is rotated to the tensioned position. Now to go use Haydn's mill to take care of that part...

Nice keep up the good work

WF?

yes

racing?

might do a drag run or two :-D

Update: car is running but not so much driving. The shift linkage is all whacked out for some reason, which must have happened when I put the new motor in pushing things out of alignment.

All of my stuff is now moved over to my new house so at least everything is in one spot.. coupe is nestled in the lift bay for fixing up the linkage and installing a few remaining details (headlights, some trim, etc). Need to do a bit of road tuning before taking it down the 1/4 mile but should be ready to roll by Friday :woowoo:

sweetness, get it dialed right in, ill see ya there, jsut waiting on a few sensors to come in so i can obsessivly monitor my motor aaha on the ride and me and soem freinds are headed down

race vs janis?

he'll smoke me as I will need some fuel system updates before I can take full advantage of the new motor.

We've raced before, I killed him off the line but then he took over at half track thanks to suck ass 3.6 cams (no power over 5500 rpm, turbos or no turbos)

ahyeah i was wondering how the upper end of the v8 breathes / revs

what kinda fueling stuff do you need and what are you gonan do for cams?

need to run new fuel lines and fabricate fuel rails. still running stock coupe fuel lines and stock v8 fuel rails which are pretty restrictive. I was getting pressure drop @ 440whp, so...

as far as cams go, the 4.2 cams are night and day difference vs the 3.6 cams. I'll be running the stock 4.2 cams.

does sound too bad def about a day job, ha so youll have it rolling on a beastly new fueling system and such for WF? i kid thats goign to be a lot of test fitting / fab etc

think youll have the new fueling done soemtime this summer? that thing has a lot more in it even on stock bottom end

hard to say, I just moved so all of my time lately has been going into putting things away and 'house stuff'. I have the fuel rails already fabricated so probably...
