Triples vs twins

Triples are often a cheaper alternative to a set of larger compounds.
Most triple applications on street trucks are either done to look cool or save money. You also are going to have to give up some space that is generally occupied by something else to fit them in.

Yeah I know a lot of show trucks do triples! Dps is telling me the triples are harder to tune and the twins they wanted me to run was with there new vgt as the pressure charger. I think that would be ok if it wasn’t new and proven but I think I’ll wait on that to see how they do.
I’ve talk to Pius about compounds and he ask u about your set up and builds the chargers to what the engine wants! He says he wouldnt do a married wastegate because he liked a wastegate on the manifold and builds to your boost level. I may wait awhile and have him built me the turbos and get crazy Carl to build a kit!
I just like the triple ideal but ain’t sure which way to go yet.

Member T-man here has a triple 363 truck with a crazy Carl's kit. Damned thing boosts like nothing I've seen.
9.87 best times 5.9 based. T-man went up for more cubes so better times comin

What?
I'm running a pair of HE351's into an HE341. $550 for all three turbos was the appealing part. The real estate they consume is the downside. The spool is decent. I would say comparable to better than the GT37/GT42 twins I used to run (if I remember right from 5 years ago). With 5x16s and a pump with just the standard parts, its clean until 70 psi of boost. That is also where exhaust likes to disconnect itself under the cab. Apparently 4" exhaust isn't enough.

I'd bet the engine is rotating enough under WOT to pull the exhaust apart. My 91 used to do that, until I put a 2' section of flex pipe just after the down pipe.

What?
Never checked my drive pressures with it. Its just a truck for picking up things and dragging the rzr out to the mountains. Tows great, EGT's always stay in check. No track times, I think I'd have G56 parts laying on the ground. No dyno numbers, but I'd estimate around 600 based on previous setups I've had. Daily drives as well as it always has. Boost response is good. Smoke when trying to drive carefully is worse after the 5x16s, but once its making 5 psi or so its clean up until around 70psi.
My boost from the primaries is around 20 psi, total around 80. It seems to hold the 4:1 through out all rpm and boost ranges. I hooked up the gate on the HE341, only to have response worsen, smoke worsen and temps worsen. I would get about 40 psi out of the primaries, but the total was only about 45, really killed the secondary. I kept restricting the gate until finally its just the actuator with no boost signal. Thats how it is today.
The exhaust coming off is 99% a flow thing. The rest of the exhaust is all on factory hangers with lots of movement. It blew the same joint off 3 times (downpipe to the rest under the cab), I fixed that good and proper, and it blew the next joint down the line that hasn't been off in the better part of 10 years. It needs either a true dual 4" or a 5", but there is no room for a 5" down pipe with how I built it. For what I do with the truck, its just fine, but I know thats hurting potential.
