Similar engine as the a8 5syl but 2mm smaller inducer on turbo with these dyno figures. It is also e-85 fuel with stoch 3b modifed motronic.

A8 at the track with 295/30-18 and e-85@700hp, racing against a porsche. I think the porsche lost

Hope it is ok that you can se the pictures of the a8 with 295-30-18 r- tires Vilhelm.

Sweet Jonus. Thanks! Guys, the builder of the A8 (master Audi builder) is here, so all technical questions about the car can go to him, so post them here, and he might answer

What about a couple of pictures of this baby. This is the Turbo that is in the car now, isn't it??

Jonus, there's some type of pressure relief system on the charge pipes, right? He mentions it has no Blow off valve, but does it have a recirculation/diverter valve? If not, how is the surge not going to destroy the compressor impellers and the center bearings?

This is definitely the sound of a boost relief valve and not surge...

WOW!!!!
Love the idea
I know where there's a 200 v8 that was ex Audi demo car in uk.
Been sitting for a while but apparently runs, 200k plus miles tho
Wonder if that would take an I5 easy enough ?

Can't see why not, as originally they where I5's My old 200 (RIP) was a 1986 model with electric memory seats aircon the lot, beautiful car to drive and dearly missed. That came stock with a 10v I5 on kjet which on the long run I was going to fit a 20v to. The later models from Europe 1989'ish came with a 20v as stock.

There is no BOV/release valve on the pipes, trust me. The pressure goes right back to the turbo, that's why you hear a "cho, cho, cho" sound instead of a "pshheee" sound. You can hear it way better in higher gears with full boost and less RPM

I asked him if this hurt the turbo much, and Jonus said it really didn't effect the turbo life.
