Re: More turbo BMW updates
Ugh.
Look - I have personally seen three instances where a "custom" manifold has hurt performance not only down low, as expected, but up high as well. I am not about to make silly guesses and use other peoples ideas of what should be done until I discover a problem. The stock manifold is worlds above other manufacturers poor excuse of a manifold - it's the last thing on my list to try and re-invent. I am neither an elitist nor a ***** - much of my automotive experience is with Volkswagens. Real elite.
You still fail to understand why I am doing the dual feed. It's going to increase the volume at the front of the pump by 2. Yes there is a single inlet, but right in front of that single inlet is the potential for 2x the amount of fuel, so it would take more effort to drain that 2x fuel back into the tank if I brake hard or turn and starve it. That's the idea. I understand a Y is going to add turbulence, but it is not adding turbulence 10" upstream of a fuel pump. Its a gravity feed pick up - the A1000 is not a sucking pump, or has a very light lift ability. Therefore, if I could put 10 lines into a single T to try and get as much volume 10" from the inlet of the pump, I would. I am preventing the chance of it starving by effectively putting more fuel closer to the in point. Of course I am limited by the single line to the pump. I am actually limited by the single inlet ON the pump.
As for the Sequencer, I have faith in B&G coming out soon - they have PCBs read, I have seen/heard friends who know about them. I could easily go out and drop money on an SM4 or AEM standalone... it'd be easy. But I am looking to try these things out as I like giving back to the community and supper the MS front.
There's no value in arguing with you - you're a trouble maker on this and other forums. You can have your ideas of how my project should pan out but until you go through the hassle of building your own identical setup, this idea remains mine. Sit back and enjoy the ride. It's easy to give advice that is not feasible. I could sit back and critique all of what you've done... but I don't care to - you did it your way for a reason. I have seen serious power made on the stock manifold. Short runner manifolds increase your HP up high but your torque falls of a BUNCH. I am not looking to make it completely boring on the street. I also have the manifold right now - that means I am that much closer to turning the car over.
As for "licking" the *** of people - all I do is ask what updates come, maybe once a week or two. Wowowowow. I have an MS1 3.0, and MS2 3.0 and a MS2 3.57 all 6 COP modified. That's not the point. I want to try the sequencer out - it looks promising and if $540 is out of the realm for a DIY well.. ----.
I just find it funny, these quotes, "550hp at the crank (max the holset) eventually when i up the boost. i'll definitely hit that" and "If I chose to build a 1000hp engine.... . and i would succeed. anyway, thats besides the point." And I am the arrogant one?

take it easy guys, no need to hate on HMT 
you are obviously both smart guys and have done cool projects, so differences of opinion is expected, but this shitfight
save it for h-t perhaps
sorry for the threadjack

Besides a pressurized fuel cell and having the pickup in a baffled lowered point should be fine to keep the fuel sloshing around, I figured that since the feed is pressurized g force wouldn't have much to say about where it's going.
Correct me if I'm wrong.
