How We Design Turbo Systems

A turbo system isn’t just a collection of parts. It’s a system that has to work together, airflow, heat, fitment, and serviceability all matter.

 

At Aronson Racing Lab, we don’t just install turbo components. We design systems that perform, fit correctly, and can be maintained long-term.

 

It Starts With Your Goals

Every build is different.

Before anything gets built, we look at:

• Power goals
• Intended use (street, race, daily, etc.)
• Fuel type (gas, diesel, E85, methanol)
• Engine and supporting modifications

 

What this means:
The system is built around your setup, not forced to fit a generic design.

 

Airflow Comes First

Airflow is one of the biggest factors in performance.

We focus on:

• Minimizing unnecessary bends
• Keeping piping as direct as possible
• Maintaining consistent pipe diameter
• Reducing restrictions

 

What this means:
Better efficiency, faster spool, and more consistent performance.

 

Packaging and Fitment

Engine bays don’t give you much room to work with. That’s where design matters.

We build around:

• Existing components and clearances
• Heat-sensitive areas
• Access points for maintenance

 

Real-world design examples include:

• Routing around components like dipsticks and accessories without blocking access
• Keeping piping tight and organized without creating unnecessary bends
• Designing components that fit clean without forcing installation

 

What this means:
Everything fits the way it should, without creating problems later.

 

Heat Management

Turbo systems generate a lot of heat, and ignoring that leads to failures.

We consider:

• Material selection (304 vs 321 stainless)
• Component placement
• Proximity to wiring, hoses, and other sensitive parts

 

What this means:
Improved reliability and reduced risk of heat-related damage.

 

Serviceability Matters

This is one of the most overlooked parts of turbo system design.

We design systems so they can be:

• Removed and reinstalled without unnecessary disassembly
• Broken into sections when needed
• Serviced without fighting the entire engine bay

 

Examples include:

• Multi-piece piping where it makes sense
• Maintaining access to critical components
• Avoiding designs that require tearing everything apart for simple maintenance

 

What this means:
Less time and cost when it comes to future work.

 

Material Selection

The materials we choose are based on heat, pressure, and overall system performance. Different parts of a turbo system require different materials to function properly and last.

 

Cold Side (Charge Air):

• Typically built using 6061 aluminum
• Lightweight with good strength
• Excellent for airflow and heat dissipation

 

Why we use it:
6061 aluminum keeps weight down while providing the strength needed for boost pressure. It also helps reduce heat soak compared to steel, making it ideal for intercooler piping and intake systems.

 

Hot Side (Exhaust & Turbo Piping):

• Built using 304 or 321 stainless steel
• Designed to handle high heat and thermal cycling

 

Why we use it:
304 stainless works well for most applications and offers strong durability. For higher horsepower and higher heat conditions, 321 stainless provides better resistance to cracking and long-term heat stress.

 

Extreme Heat Applications:

• Stainless Schedule 10 piping is used in the most demanding environments

 

Why we use it:
Schedule 10 stainless has thicker wall construction, making it more resistant to extreme heat, pressure, and fatigue. This is typically used in high horsepower or race applications where standard tubing may not hold up over time.

 

What this means:
Each part of the system is built with the right material for its job, not a one-material-fits-all approach. This leads to better durability, improved performance, and a system that holds up under real-world conditions.

 

Built, Checked, and Refined

No system is perfect on the first try without checking it.

Every build goes through:

• Test fitting
• Adjustment and refinement
• Final welding and finishing

 

What this means:
A system that fits right and performs the way it was designed to.

 

The Bottom Line

A well-designed turbo system isn’t just about making power. It’s about making power reliably, efficiently, and without creating new problems.

 

At Aronson Racing Lab, we build turbo systems with performance, fitment, and long-term serviceability in mind.
