Please tell me that this is in no way a gd design for routing IC piping

The IC itself is very efficient and effective. The plumbing is a compromise at best.
That same IC with the end tanks swapped into a z config has excellent sustained boost IAT numbers, little pressure drop and very good throttle response.

What are the IAT's? Because I did some testing with my setup.
In 70 F deg weather I was able to get down to 27 C at WOT during a 2nd-3rd gear run. During normal driving the IAT's were at 36-37 C.

With your current set up? At what boost pressure? The setups I've seen data on were a chipped K03
and a GT28R .. both put out a fairly high turbo outlet temperature. The bigger turbo had IATs in the mid 30s ..
By contrast I saw IATs in the very upper 60s and lower 70s with the OEM SMIC and in the mid to upper 40s with the SPP/RaceTec

Yes with the GT35R and custom 26.5 x 11 x 3 fmic(20" core)
boost levels were 16psi on 91 octane. Next time I hit the drags I will log the IAT's to see what they are during a full run of 20+ psi.

It will be interesting to see what the IATs show at the higher boost.
The data I've seen for the APR vertical IC and for the data I posted on my SPP set up are after multiple runs under max boost. It appears that the IC hits equilibrium right around 100 f. Looking at the logs of mine I'd say mine hits equilibrium closer to 116-120f
