"AUDacIouS4" Allroad Prescision Turbo 5558 build

[AUDacIouS4]

The Wagon Mafia hit Chuckwalla Raceway last weekend. Man this car is fast!! I was hanging with some fast cars. I play on the street a little here and there when it's safe, but this is the first time I have really driven it hard. I sold my Cayman which I had been tracking for the last two years so I thought it would be fun to go rip the wagon! Halfway through a session I started shooting fireballs and the car lost boost so I pulled off track and found that the turbo compressor outlet hose blew apart! That's a first for me. Nothing a little duct tape and a clamp can't fix! I was able to drive 150 miles home, so always carry duct tape and zip ties!
Oh, and my water pump went out last week at 77k miles, so that was fun fixing that. A new one was $420 at the dealer with a 10% discount. For those who haven't replaced one yet it only takes about 2 hours to swap one out.

It's been a minute Audi brethren! 40,000 miles into the big turbo build and the car still runs great. My wife mostly drives the car now and I was considering selling it this spring. I wanted to reach out on here to see if anyone is interested or else I will list it on BaT when the time comes.

True testament to it's reliability. Congratulations and all the best in your future builds.

This thread has been useful to my 13' A5 Sportback B8.5 big turbo build. Currently limited by the brushless LPFP giving in at 27psi, 5700rpm 4th gear. ECU closes throttle and limits boost. You can 'trick' the system by letting off partial throttle for a sec then WOT again and it picks up boost pretty well till 7300rpm redline. Theory we are running with is that the LPFP is struggling to meet the fuel requirements hence the throttle shut.

BACKGROUND
The car has a built engine; rods, pistons, valves, springs, retainers, bearings, headstuds... went with a custom twin gate tubular manifold from Lunchbox Fabrication, two TS Hypergate 45s, TS Raceport BOV and a 'G30-900' equivalent 6255 Pulsar Turbo with a 3" full exhaust. Currently running Golf 7R DI injectors, VIS HPFP piston upgrade, Stock LPFP (8k0919051ad) same part no. with B8.5 4.2 NA RS5. Car seems to have maxed out this LPFP at 450bhp. Strange as RS5 come with 444hp stock
