I think I have a Bosch one I can bring and you can have. I also have a Baileys I could bring, but I'd need it back as it is for my Porsche.

My 710n is holding up fine at 28psi with a GTX3071.

Are you sure the diaphragm is good?

I havent had the time to inspect it. It will hold a vacuum if I suck on it. Something is opening up and releasing pressure. The car will run at 1bar (0 psi) like an N/A car until I release pedal and get on it again

So I'm here again in La Grande. I now have 3 speeding tickets from this car as well :bangshead:

We discovered that the vacuum line going to the bpv had a few big holes in it. Threw a new line in and still getting the sudden boost lost issue. I know theres a hole in the MM hose but I just dont see how it would cause sudden boost lost. We'll try a diverter valve while I'm down at BBQ.

The hose might cause an issue where the rip only decides to open up at higher boost.

replace that hose and you might see an improvement.
You using a stock mc1 michelin man hose?

Be careful!

Kinda funny, the fastest I've ever been in my 200 was when it was almost completely stock. 145 was the number.

What will the 200's do top speed wise? With stock 016? I'm sure someone here has tested it.

BTW nice car taco! 150 mph in a old school audi must feel like 200 lol

Thanks!

Theoretically, it can do about 165 with a 20vt as it has 3.89s and a rev limter at 6400. 20vt no idea what their limiters are

150+ in a properly sorted oldschool Audi felt as good to me as anything. MUCH more confidence-inspiring than anything Japanese or American that I've ever been in the triple digits with.

lol floating would absolutely be the word. The scariest part was realizing how useless stock g60 brakes are over anything 130+.... well lets say MORE useless at those speeds :rofl:

taco when are we going to see some 200mph runs?

Your 150 mph club thing got me thinking about my car so I did some calculating...for you to hit 150mph with 411 gearing, 205/55/15 tires, and a .81 5th gear you would have to hit just over 7000 rpm. at 6k rpm you are doing about 130.
