For those who are running the stage 2, I would like to know whether there are any oil consumption issues similar to what has been reported on the RBs from time to time.

I have RBs no oil consumption at all....why are you having some? If so maybe that's another issue he can address or already did since the stage2 v2 are in production. That's if you're having a problem that is, which I highly doubt you are.

That is a good question. I've been trying to find that out for some time.

Why would you doubt that I have a problem? I would be surprised if you knew my car so well that you can claim with certainty that there's no problem and the oil is disappearing because of my vivid imagination.

I was saying that because his turbos just came out not to long ago that's all. You should not be having oil consumption problems. How long have you had them? Are you see any type of smoke?

I think it was a simple misunderstanding. You didn't state that your RB's were having an oil consumption problem in your first post. You made a general statement about some RB owners having the issue.

It looks like you have a 60-130 mph option on your device. Can you give us that time too as time permits.

No way I can do it less that 8 sec. 60-130 that is 96-209km/h and ny the best time was 7,9. In the summer I can do it in aprox 8,1-8,5. Will measure 60-130 but it would be more than 9 sec. No way less. Friend's Porsche turbo 997 can do it in 7,6 sec, anything under 7 is f... fast!

Slope is corrected to 0.00 via DBSCANNER.

But it was driven on a + 0.20 slope with a 7.01 and after that I corrected it to a 0.00 slope. Result was 6.98 seconds.

Concrete numbers tomorrow but they are hoping around 440-450whp easily on the mustang which is right around 500whp on a dynoqueen!!! haha. More updates tomorrow people thanks for being so patient!!!
Your goal is very challenging. Just be careful and don't push them too hard. The back pressure can get too high for both the turbos and the engine. I posted some useful info on this thread some time ago, that should help in keeping the goals reasonable:

The fact that think and are posting that the stage 2 turbine wheel exducer is .1mm larger than stock is hilarious. Jippi doo back with more misinformation. Keep it up buddy!

Edit: .1in or .1mm he is still completely incorrect and is spreading bs

well I think he's kinda setting you up with potential "new" news from Mike. I don't know exact dimensions but your rev1 has a smaller turbine which directly effects VE. And combined with a larger compressor, WGDC could be perceived as safe(ish) relative to stock turbo experiences... but this may not be the case, especially if trying to reach a certain HP goal.

It is normal, Tony send documents with the turbod that explains the very fine sand in them. All your mechanic needs to do is blow it out and your good to go.

Its not sand, its not even close to sand. Its is a very soft material made of plastic and glass used to clean the inside of the housings. There are pockets it can get stuck in. These are cleaned twice and hot tanked twice after, and yet some can still remain due to the way they weld the housings. It cannot hurt anything as it is 10 times softer then any other materials it comes in contact with. Blow out the little you can see and whatever remains is instantly blown out the exhaust on start up, its that simple. Most people email and ask, but I see you like to go straight to the forums. Noted.
