    Game on!

    Glad to see this post. I'm a little biased but I know how much hard work went into development of these original and unique ideas.

    People are talking about compressor efficiency like it's the big difference and as a turbine guy... it does make a difference but not night and day. As stated above 20 psi isn't 20 psi. Here is an...

    You do have a point overall but I know the inspection criteria on mounts and it's pretty tame. My point was that mounts in general don't have to be matched. It's intuitive if you consider the...

    Many aircraft engine applications use mounts that are different in design on different parts of the engine, i.e. one mount is just xy plane, one is xyz, one is z. Mount durometer may differ or they...

    This group typically only demands test data on new designs, it's acceptable to eyeball and estimate that OEM designs are lousy, lol.

    I like having mine on at about 8ish psi. Of course, my tune pulls some fuel (via scalar) at that load range so it's a seamless transition. I still see a low 11 or high 10 a/f spike but never feel...

    My 335is clutch finally started to slip. I got about 20k miles out of it at/above 500 whp, current tune is around 560 whp with about the same torque, maybe a little more. Anything is possible but...

    Good stuff. During the development phase I had a solenoid go bad but it's fairly rare. Glad to see you're back up and running strong.

    I've been using Motul 8100 X-cess 5w40 with pretty good luck. I get blackstone reports every other or every 3rd oil change, and normally change every 3000 miles, but there have been a couple times I...

    If the TBI is spraying while at idle I'm not sure the car would even run -we did some testing in the development phase and verification that it was spraying after hooking things back up was just to...

    Sort of. On some shifts the throttle will stay open and boost doesn't bleed off very fast. It's easiest to see this work in a 1-2 shift. Start first gear fairly low and wind it out then just push...

    The more the ecu has control over fueling, I think you're probably better off, but you're right in that the need is somewhat diminished. I wonder how it'd do with a throttle body ring; just enough...

    WTF! I hope that's what happened and if so, you're a lucky s.o.b. Would be funny if that's why the car that engine came from got sold.... lololol

    Nah dude you misread my response. You touched on the "go with proven (non VTT) " mentality, which meant you referred to the idiotic mentality, not that you shared that mentality. That's why I said...

    I have over 20k on my VTT 2+'s on VTT inlets and they're going strong. Fuel is E66, boost is ~26-23 psi. No issues so far. I daily drive the car fairly hard and never had any turbo or boost...

    It'd be really easy to tell if it's a spike or not by looking at the log. On the graph, it really does look like a spike, neg rep away if you don't understand smoothing or spikes and want to show...

    I like it. I'd suggest looking into fuel valve operational characteristics from turbine engines for some hints on how to make the damned thing work better.

    I'm the VTT2+ guy on the 550i/335is clutch. It just started slipping on me, took about 20k miles to do so. I drive aggressively but don't launch/slip much. It was a good value but I'm replacing it...

    It's going to be very difficult to say if it was assy error or surging. When we blow something up in the test cell we have probably 200+ different parameters being logged, and that's if there is no...
