Turbo log manifold for a silverado
Hey I am thinking of building a diff setup for my truck. I currently have a fully divided 2.5" truck manifold forward hotside. Spool time currently is not the best. Underhood temps are pretty bad, and I'm tired of fighting piping etc. when reinstalling the kit.
So, my next step is to try my luck at building a turbo log manifold setup. I am planning on ordering all the parts in sch40 mild steel.
As for the header primary tube size I'm thinking of 1.5"
Log manifold main body 2.5"
Crossover 2" or 2.25"
This will all be going into a t6 s480 turbo. My questions are do u think the the sizes for the manifold will work ok? will 2.5" main log body work or should that be 3"? Maybe a lil bigger for crossover size?

well I'm shooting for the fastest spool time possible. This big s480 is crazy laggy with the 5.3, with the 6.0 it wasn't near as bad.
What about a 2" crossover? any hp to be sacrificed with it being that small? Just curious.
And I'm guessing the 2.5" is fine for the main body of the log manifold?

The kit I am currently running used primary tubes with ID of 1.5" and the manifold outlets are 1.875 (yup 1 7/8"). That's how the kit came. Spools lighthtning fast with a 7675 and 6.2L (0-8psi in 0.7 sec according to my logs), I have made 818rwhp @16psi with burnt plug wires. Should be close to 900rwhp if I could keep spark.
if I were building a new kit the primary tubes would be be 1.75" and 2.25 or 2.5" log based on my cubes and turbo.
for you, I think 1.5" and 2" is a good compromise.
