its a factory manifold with the inlet ported and a peace of 4'' pipe welded on then the turbos feed into a y with a 4'' outlet that is connected to a 4'' silicone boot feeding into the intake.

yeah I know what u mean it could have been done better but its whatever cause as far as i know nobody else has one and i'm also only 18yrs old so i tend to rush things.
the reason i built this is because no one where i live has a built idi its all cummins and powerstrokes. I could have thrown a turbo and injectors on my cummins with studs and easily made more power but it would just be like the othere thousand cummins out there. But if u want this comming winter i could send u the manifolds so u now exactly were the turbo flange needs to be and u could make a set of headers that line up the same for urs.

i know what you mean there i helped abuddy of mine build a 93 cummins with the rotary pump b/c he wanted something different i will try and get his dyno sheets but i think it ran about 650hp fire ringed total arp studded bored pump injectors turbo and lots of tuning

Those 57mm compressors will spool damn quick. That thing will be a monster down low! Have you all thought about doing something like the Banks Big Hoss intake for the Duramax? That would be sick looking on an IDI plus it would be perfect with twins. I'll try to find a pic.

It's good to see somebody else thinking outside of the box with twins.

You can equalize the pressure in both sides of the intake by making it look like an "H" with a pipe flowing air between both sides or you could even do it in a "U"shape like Hypermax did on their build back in the 90s. Either way I agree, the pressure would need equalized between both sides...
