4.2 breathed fire for the first time in the Allroad today! Sounded absolutely rowdy with open headers! Now to get the 2.0t in the RS5 chassis so can move it/get the purple wagon in the garage!

I think I’m going to downsize the turbos from a .83ar down to a .62ish
The lags not the greatest and these antisurge turbos don’t really produce the spool sounds I was after LOL
Car is holding great in the 7-8psi range.
Do I try for 10-12psi? Still waiting on the JHM supercharger kit. Hoping that’s still in the pipeline as I’d like to fab up a nasty set of 5-1 headers and see how far I could push it with the port injection.
Why not add more boost??
I hope JHM is still pursuing as well. A new IM nowadays is halfway to the cost of a JHM supercharger kit.
Not sure how much boost these engines can take, I don’t think anybody does!
I’m at 12° of timing and 8psi of boost. Biggest debate for me is do I increase the timing while keeping the same boost or increase boost and continue to run moderate timing??
I still have yet to turn on the VVTI stuff and tune for it so maybe that should at the very least be first haha
I’m amazed it’s running like it is with no VVT lol That would definitely get my vote for next step.
There are a few of us that know. LOL. Looks like fun

Still enjoying the crap out of it. Haven’t had time to do any work on it, but she’s been rock solid this entire season! Once school slows down I’ll be pulling the motor/trans for some “upgrades”
Does anybody have the factory engine hoist brackets that attach to the head? I seemed to have lost mine.

I never ended pulling the engine… instead pulling everything else! Car got a brand new Ringer Racing Stage 4+ Billet clutch, and some new seals/gaskets.
“While I was in there” I machined the turbo compressor housings for the T51R mod as well as recirculated the Tial wastegates into the downpipes.
All in all, a decent bit of work but absolutely worth it in terms of sound! The boost controller is connected so I will be upping the boost to around 10-12psi this year

Noooooooo! Just saw IG 
How bad is it?
Oh it’s bad… I’m on the hunt for a new motor LOL
Oh no!
What do you find out about the motor?
I have yet to tear it apart, but she was choochin
Oh that’s terrible!
I won’t know for sure until I get the heads off, but it does appear to be a headgasket failure between cylinders 6 and 7.
10psi of boost and 12° of timing seem to have done it for this ol girl!

Gotcha so if anyone follows your footsteps keep it at 7 lbs lol… look forward to updates!
I got greedy. The car was incredible at 7psi and would knock the socks off my RS5. I already have a new engine and picked up some Lamborghini 5.0 Gallardo 5-1 headers… they definitely require some work…
Going for 500hp N/A with the same port injection RS6 intake manifold.
