Thats not really what this thread is about, but whenever I get the chance to go ill post up.

 

incorrect, the borgwarner turbos are available in undivided or twin scroll(divided), The S588 is available in undivided. The S500 is available also from Reed in undivided




also any shop that builds turbos can modify the housing

 

I stand corrected then.

 

Was the log 2.5 or 3in id?

 

I think you need to add a hug roots style blower on top to take care of that spooling problem

 

Great info here. I like the new hot pipes especially the wastegate dump pipe. I am doin mine very similar except mine still has the crossover around the back and its header style Instead of a log.

 

They are 2 1/2" pipe which is just over 2 1/2" id.

 

Oh, I always thought it was 3", guess thats what I get for not measuring!

 

Another reason the log manifold works aswell as it does is cause the waist gate is before the log, I know it's not going to make a huge difference but your bleading off a fair amound of ex that never has to go throw the log, if the waist gate was right before the turbo like it is now I bet you would have seen more gains then you did.

 

Nice results. They pretty much match what I saw when converting to truck manifolds that Y together just before the turbo.
Turbo headers produce even less back pressure but its almost negligible unless hp is up there. I need to find my compare notes but less than 1.5 rings a bell.
I know exactly what ur describing in regards to spool up. With a Y design it's very predictable and comes in almost linear vs almost instant. Kind of decieving because the truck is pulling but the instant rush of torque is spread out. And talk about how hard the style pulls in the upper rpms is crazy. . I prefer the linear pull.
All the kits work great and it shows just depends on far u take them.
