I had it running with the stock bottom end and just the hot side connected with no wastegate. Pulled it out ,built the motor put it back in the car in less than a month! Just the details and plumbing left.

I might be wrong but I don't think 2 walboro 255 will supply the motor the fuel it's going to need....your build is alot like mine and I have a big *** pump and converted to return style fuel system....just a thought.....good luck with the build it's going to make alot of power....

I am still up in the air on the 2 pumps. When I talked with Nasty performance, they said they have had as much as 930 hp to the wheels with the double pumper, and it wasn't running out fuel. I haven't bought the pumps yet though. I wanted to use the feature built into the BS3 to activate the second pump under load via TPS. I am open to ideas though.

let me know how it turns out, I'd like to at least compare dyno graphs with you concerning our different A/R Housings. What are you doing with the intake valve seated spring pressure? I've been in the market for a 1.08 for a while now, I just cannot justify it as the car is in all fairness just a street car.
Other than the compression ratio our builds are very similar.

Yeah the E85 throws a wrench in it. I think I will look into something a little different on the pump. Anyone had any luck with the Magnafuel stuff. Or dare I ask Aereomotive pumps???

The springs are the new Extreme Patriot dual springs. Rich at WCCH set them up for me, I can't remember the numbers on the pressure. Maybe he can chime in?

The pics can now be seen in detail at this photobucket link

If I can figure out how to upload video from my phone, I have some footage of it running with the stock short block/LQ9 heads.
