Chevydan, I don;t know what the bleed pipes are??
Phil, I see what you are saying, but if possible, cite me to a better inake elbow, if one exist, so I can see the difference between this one and a "better" one so my mind can start thinking about that issue. Thanks.

Jax04, what filter mesh thing? Are you taking about the old air filter on the turbos? If so, these turbos have a 5" intake and it matched up nicely with an edelbrock carb foam intake filter. I am not using any filters anymore, but if that is not what you are referring to, let me know.
As far as the carbon fiber valve covers, what a waste. Last thing I want it to start cleaning up an oily mess on my nice new block. I'll give them a try anyway and watch them closely.

A few more pics from when we tried to dyno it to test the converter out. This is when we noticed the head leaking. Head studs pulled threads out. That was the iron 6.0 truck block 402ci. That wasted yet another year of the build. It was in October 2009. It took that long to get the new engine built mainly because I did not have the entire amount ot money to drop on it, so I had to go slow.

A few of Madman's pics from when it was in his shop. Madman took good care of the car and it came back without one single scratch on it. But don;t tell him that because I like to tell him he screwed it all up. Also, here is the BMR k member that accomodates the dual 4" exhaust.

thank you. I might have to look into that. Im currently running a mesh deal i made, but i dont like it. Thanks! Ill look them up!Again, this looks great man! Incredible job!
Im assuming thats just powder coat on the housings? (compressor)

Yes, just powder coating. Measure the diameter of your compressor intake and look at some carb filters with the washable foam. It works real well. I never had problems with it becuase it flows so well with the foam. Mine were the triangular shaped edelbrock intake filters. They are inexpensive to boot. I would feel more comfortable with that than with a mesh screen that could come lose and end up inside the turbo.

I guess over time it could break down, but mine were several years old and the foam was still very strong. However, I know form the past (1980's) with using them, they do tend to break down over time with the heat. I did not have that problem at all with my turbo Camaro and I would think if you changed the foam every couple of years it would not be a problem. Just my experience.

As far as the back two cylinders issue, I do not believe that is an issue at all with boost. Once you get a couple pounds of positive pressure, that issue becomes moot. With natural aspiration, the intake manifold is everything an I agree that an improper carb placement or manifold build could leave some cylinders lean as hell. With boost, there is positive pressure just waiting for the cylinder when the valve opens up, so not issue whatsoever. I had to think about that issue for a while to get it straight in my mind.

its not a lean issue, its a cooling issue. with the power you're making you should be using kurt urbans water vapor system, or whip up something like it. its pretty critical, those rear two cyls can get hot and cause lots of problems.

which its not, just a measurement of restriction, which means if there is a problem with the intake, then its still there with boost

LOL. You might atleast take what Phil says with a grain of salt. If you dont indeed research the matter further before you write it off. It only takes 1 cylinder, much less 2, to go lean and make for a very bad day. I used to think the way you do about boost. It seems to reason if you have positive pressure through out an area, plenum, space, etc, it is equal because of the function of pressure. Not really true. Direction of flow, turbulence, and siphoning effects blow that basic theory to hell. When you have high amounts of air that are turning a corner quickly, the mass of air creates turbulent pockets, and/or voids depending on how you look at it.

If "it all evens out"when you apply boost than there would be no need for sheetmetal intakes with proper airflow distribution. Don't sweat it, I'll wont make any more stupid posts here.

I'm just trying to open up eyes to a problem that is going to come out very soon. I could really give a **** if the OP takes the advice, its not my motor. I work with hundreds of guys around the country with my AMS-1000 consulting service and see plenty of data that supports my position.
