We take great care in selecting which components would offer the best combination of performance, durability and value for all of our cooling packages. Not only for our test car, but for yours as well. It’s this passion for improvement that led us to working with Matt at Dedicated Motorsports in order to to offer there track proven main front HX to our clients as well. When it came to the AUX coolers, we were not satisfied with what we found existing in the market, so we worked with our friends at CSF to modify an existing design, in order to give you more flexibility and better performance.

MAIN HX: This custom DMS designed and CSF built beauty not only increased the size of the HX but also increased its efficiency through the use of CSF's B tube technology and ultra efficient multi-louvered fins. As you may have already figured out, upgrading to a high flow coolant pump is useless if you have major system restrictions like factory heat exchangers. DMS helped alleviate these restrictions and added flexibility with the addition of -12ORB inlet/outlet fittings. This allows the end user to choose the inlets/outlet size of either -12AN or 3/4 Hose barb.

AUX HX: GMS worked closely with the team at CSF to make some improvements to their existing #8207 design by removing the fixed GM quick connect fittings in favor of a pair of -10 ORB female bosses which gives you the flexibility to run the OEM 5/8” quick connects (included in the box), push lock or AN fittings of your choice. We also changed the finish so all three units match in color and finish to provide uniform aesthetics as well as proven cooling results. The ORB bungs also allow you to remove the OEM 5/8” hose / fittings and upgrade to 3/4” between the AUX and Main HX by simply installing a -10 ORB to -12 AN adapter. Note: In an effort to maximize the size of these units, cutting the upper bracket in one corner may be needed on some cars. Additional modifications will be needed for the 3/4” option depending on the fittings and preferred hose routing. It’s not that bad, we can help. This effort to upgrade to 3/4” fittings and hoses yielded us a 20% increase in flow using the factory pump!!!

Each CSF Radiator design, custom or not, undergoes rigorous testing before it is brought to market. Testing includes:
-Individually leak tested
-Vibration cycle tested
-Thermal cycle tested
-Wind tunnel cycle tested.
-Burst pressure and impulse cycle tested for strength
-Salt spray tested for corrosion
-10 foot box "drop test" to ensure packaging protection

Not only are these CSF built beauties more efficient and more durable than OEM but they also help add more capacity to the supercharger cooling system. Combined this trio hold approx. 235% more fluid (14 cups vs 6 cups) which adds just over ½ gallon of HX coolant with this set alone.

GMS takes pride in offering the very best components for your car. As LT4 purists, we want to squeeze as much power as we can from the LT4 factory 1.7L blower. As most of you know, making big power with these compact blowers often means spinning them faster, which is a double edged sword. As the blower speed increases, so does the heat generated by the blower, which quickly illuminates the weakness of the factory HX cooling system. So whether you are simply trying to keep your otherwise stock ZLE happy on the track, or your 1000HP street racer is combating your sky rocketing IAT’s this HX combo will help.

Want to keep track of your IAT’s and oil temps in real time? Add an incredible Banks iDash to your cart for maximum monitoring capabilities.

Whats in the box:

(1) DMS Main Front HX (with 3/4” barbs)
(2) GMS Aux Coolers (with removable 5/8” Quick Connects)

What YOU will need to provide:

Patience and attention to detail for installation... or, someone like that, who you trust with your beloved, adorned, magnificent, earth shaking, alarm sounding ZL1.
Cut-off wheel for a quick trim to the upper AUX cooler bracket no matter which fitting set up you choose.
-12AN to 3/4” hose set-up requires a 1-3/4” hole saw, -10ORB to -12AN low profile adapters and your choice of fittings. We suggest using 3/4” silicone hoses for this option, as well as 120 degree fittings. Email us if you want a turn-key solution for fittings as well. Our AUX Cooler fitting package can be found HERE.
More 50/50 coolant. Some nice hose pinch clamps are a big help here also.

Fitment: 2017+ Camaro ZL1 + 2016+ CTS.V

GMS Triple Heat Exchanger Package: Solving the LT4 Heat Problem the Right Way

The LT4 platform is one of the most impressive factory supercharged V8 engines GM has ever produced.

But once you start adding:

More boost
More timing
More aggressive driving

You quickly run into the same problem every high-performance LT4 owner eventually faces:

Heat Soak.

Not just coolant temperature.
Not just oil temperature.

Supercharger system heat.

And once intake air temperatures begin to climb, performance starts disappearing fast.

The Hidden Power Loss Most Camaro Owners Never Realize

Many owners focus on:

Pulley size
Camshaft choice
Ported blowers
Fuel systems

But they overlook one of the most critical performance limitations on the LT4 platform:

Heat Exchanger efficiency.

Because the Eaton TVS supercharger creates heat every time it compresses air, and that only gets worse as you spin the blower faster.

As boost increases:

Air temperature rises
Air density drops
Knock sensitivity increases

The ECU responds by:

Pulling timing
Reducing power
Increasing thermal protection strategies

The result:

Inconsistent performance
Reduced horsepower
Slower recovery between pulls

This becomes even worse:

On track
In hot climates
During repeated acceleration
On high horsepower builds

The Problem with the Factory LT4 Cooling System

The OEM system works reasonably well for a stock vehicle under moderate use.

But it becomes overwhelmed when:

Boost is increased
Airflow is improved
Ambient temperatures rise
Vehicle speed varies

The factory limitations include:

Limited heat exchanger surface area
Limited coolant capacity
Restricted coolant flow
Rapid heat saturation

Once heat saturation occurs, the system struggles to recover.

That means each pull becomes progressively worse than the last.

Why Intake Air Temperature Matters So Much

On an LT4, intake air temperature directly impacts:

Ignition timing
Knock resistance
Air density
Power consistency

As temperatures rise:

The ECU removes timing
Combustion efficiency drops
Power falls off dramatically

This is why two identical cars can make completely different power depending on cooling efficiency.

The Solution: GMS Triple Heat Exchanger Package

The GMS Triple Heat Exchanger Package was designed to address the real limitations of the factory LT4 cooling system.

This is not simply a larger heat exchanger.

It is a complete cooling strategy designed to:

Increase thermal capacity
Improve heat rejection
Improve coolant flow efficiency
Reduce heat soak
Improve recovery between pulls

Why Triple Heat Exchangers Work Better

The biggest advantage of a triple heat exchanger setup is increased surface area and cooling capacity.

More surface area means:

Greater heat transfer
Lower coolant temperatures
Faster recovery under load

This becomes especially important on:

Ported blower setups
Higher boost combinations
Ethanol blends
Road course vehicles
High ambient temperature environments

The Importance of Coolant Volume

One of the most overlooked aspects of intercooler performance is coolant volume.

More coolant capacity:

Slows temperature rise
Increases thermal stability
Reduces rapid heat saturation

This helps maintain more consistent intake air temperatures during aggressive driving.

Flow Rate Matters More Than Most People Realize

Cooling efficiency is not only about heat exchanger size.

Flow rate matters.

A properly designed system improves:

Coolant circulation
Heat transfer efficiency
System recovery speed

This becomes critical during:

Back-to-back pulls
Track sessions
Stop-and-go heat loading

A system that cannot move coolant efficiently will eventually heat soak regardless of heat exchanger size.

How Heat Soak Kills Performance

Heat soak is cumulative.

Each pull adds heat faster than the system can remove it.

The result:

Rising IATs
Timing reduction
Reduced power consistency

This is why many high horsepower LT4 cars feel extremely strong on the first pull—but progressively slower afterward.

The cooling system simply cannot recover fast enough.

Why Larger Cooling Systems Become Mandatory on Modified LT4 Builds

As horsepower increases:

Cylinder pressure rises
Boost rises
Supercharger discharge temperature rises

This creates exponentially more thermal load.

At higher power levels, upgraded cooling is no longer optional.

It becomes a reliability and consistency requirement.

Real-World Benefits of the GMS Triple Heat Exchanger Package

Proper intercooler cooling delivers benefits in multiple areas:

Power Consistency

Lower intake temperatures help maintain ignition timing and consistent horsepower.

Improved Recovery

The system recovers faster between pulls and during aggressive driving.

Better Knock Resistance

Lower temperatures improve detonation resistance and tuning stability.

Improved Reliability

Reducing heat reduces stress on:

Pistons
Rings
Bearings
Head gaskets

Better Track Performance

Road course driving places enormous continuous thermal load on the LT4 system. Improved cooling becomes critical.

Why Bigger Isn’t Always Better

One of the biggest mistakes in cooling upgrades is assuming that simply installing the largest possible heat exchanger solves everything.

A properly engineered system must balance:

Surface area
Airflow efficiency
Coolant flow
Pressure drop
Packaging

The GMS system is designed around the real thermal behavior of the LT4 platform—not just oversized parts.

The Difference Between “Peak Power” and “Repeatable Power”

Anyone can make a hero dyno pull.

The real challenge is maintaining power repeatedly under heat.

That’s where cooling separates serious builds from unstable ones.

The GMS Triple Heat Exchanger Package helps maintain:

Consistent intake temperatures
Stable timing
Repeatable performance

Not just one good pull.

Why Buy from Griffin Motorsports

You’re not just buying a heat exchanger.

You’re getting:

A system designed specifically for the LT4 platform
Real-world testing and experience
Proven solutions for high horsepower applications

Everything offered is selected based on:

Real thermal limitations
Real track and street conditions
Real performance results

This is about solving the actual problem—not just selling parts.

Who Needs an Upgraded Heat Exchanger System?

If your Camaro has:

A pulley upgrade
Ported blower
Camshaft
Ethanol blend
Increased boost
Track use

You should strongly consider upgraded intercooler cooling.

The more power you make, the more critical cooling becomes.

Final Thoughts

The LT4 platform responds extremely well to modifications—but heat management becomes the limiting factor very quickly.

Without proper intercooler cooling:

Timing gets pulled
Power becomes inconsistent
Reliability suffers

The GMS Triple Heat Exchanger Package is designed to address those problems directly by improving:

Thermal capacity
Coolant volume
Heat rejection
Recovery rate

Because making power is only half the battle.

Keeping it consistently is what matters.
