I am going to have to be WAY over 20 PSI to have the DR650 doing most of the work. I easily held 17 to redline before. Maybe if I tried going all out and ran 25 PSI it'd be a problem.

I am totally injector limited and this car will probably NEVER see over 18 PSI or so even when i go to bigger injectors. This is not a race gas car.

If there was a problem it would be easy to feel this out of balance condition your theory suggests at high RPM/ high boost and believe me it is as smooth as ever.

So, whenever a post like this comes up inevitably you are going to post how the theory says boom and I am going to post how in practice there are no problems.



Edit: Oh and the reason for no race gas is I don't see the point of producing track results I can't produce on the street because I drive this car every day. It is my ONLY car.

Edit2: I am sure you have seen the stock downpipe. How's that for equal flow!

Thats basically what I am saying.

You can run like this as long as you don't push the setup where 1 turbo is doing all the work and the other is way out of its efficiency range.

For that matter thats exactly what I said. The wierd thing is I don't have to break things to figure out how they will break. Riding around on low boost won't ever do anything to our bottom end but for what you risk and what you gain is it really worth it?

Example being a 9b/13g setup. Phalse already ran 11.7 with that years ago. Don't know if it was a true L turbine 13g' or a 9b converted to 13g (same turbines). You can do that big deal. I am not going to recommend something to any 3s owner when their is no real benefit to doing so.

For you both your turbos are within their efficiency range so big nothing. You can roll like that forever. Now if you get fuel and meth or whatever to where you can be outside the 13g's efficiency range consistantly everytime you go WOT then you fall into the POTENTIAL damage area with unequal balance between the banks. It won't fail immediately, it won't fail in 10 miles or even a 100 but it will fail sooner than if you had your engine balanced with equal turbos/backpressure.

When that is, who knows, I have no desire to find out, and like I said our motors are pretty stout, but they are metal, they don't get stronger with use and or abuse. I just want mine around as long as possible and hope you and other 3s owners get the same.
