📣 The CSO solution is here! No plastic. No warping. No compromise.

Cannonball Garage CSO McLaren Billet Valve Covers were engineered to eliminate the weaknesses of the factory plastic design and provide lasting protection where it matters most.

➡️ We completely redesigned the internal geometry to eliminate potential contact between the camshafts and valve covers. That means no internal plastic contact points, no plastic shedding, and no debris entering the engine.

➡️ Precision-machined from billet aluminum, the covers remain flat through repeated heat cycles, resist flexing and distortion, and maintain more consistent gasket compression for improved long-term sealing.

➡️ Additional improvements include deeper spark plug tube seal engagement for better oil control and a stronger, more consistent seal across the bridge section to support crankcase scavenging efficiency.

📱Only FIVE sets are available in this limited release. Contact Jordan now at 847-829-0060 to secure yours!

⭐⭐⭐⭐⭐

"I couldn’t be happier with the work Cannonball Garage did on my McLaren 720S. They built it with their CSO R-Spec engine package, and the quality, attention to detail, and craftsmanship are second to none. From the beginning, the team was knowledgeable, professional, and kept me informed throughout the entire process.

The car runs flawlessly and the performance is incredible. You can tell they truly understand the McLaren platform and take pride in building engines that are both powerful and reliable. If you’re looking for a shop that stands behind its work and delivers top-tier results, Cannonball Garage is the place to go.

Huge thanks to the entire team for building my dream 720S. I wouldn’t trust anyone else with my car, and I highly recommend Cannonball Garage to anyone serious about performance and reliability"

We’ve gone racing! So we’re closed.

Today Friday August 28th, the front office lights will be off. Phones might be quiet. Emails might wait.

But in the shop?

Business as usual.

Engines will still be coming apart.
Cars will still be going up on lifts.
Techs will still be wrenching like nothing changed.

Because horsepower doesn’t take a day off.

If you need us, leave a message or send us a note and we’ll get back to you.
If your car is already here… just know it’s still in motion.

Cannonball Garage. Even when we’re “closed,” we’re working.

Call the shop. Send us a message. We’ll catch up with you Monday.

A McLaren engine built by Cannonball Garage is fundamentally different. The CSO components were co-designed by our head of special operations in collaboration with top-tier manufacturers.

CSO Exclusive Engine Components:

➡️ CSO MLX Head Gaskets: Our CSO MLX head gaskets feature proprietary cooling ports and custom thickness options that allow us to compensate for material removed during head decking. This preserves proper geometry, compression ratio, and piston-to-valve clearance.

➡️ CSO Connecting Rods: CSO connecting rods are manufactured from a proprietary material that dramatically increases strength while maintaining factory weight. Maintaining OE rod weight is critical on a flat-plane crankshaft for proper balance and longevity.

➡️ CSO Main Bearings: CSO main bearings are the only McLaren bearings available in multiple sizes. This allows us to precisely set oil clearances for any application, whether using factory main bolts or high-yield-strength fasteners.

➡️ CSO-Spec Total Seal Piston Rings: Developed exclusively with Total Seal, CSO-spec piston rings are engineered to complement the factory pistons and cylinder sleeves. The result is superior ring-to-cylinder seal, increased performance, and reduced blow-by.

➡️ CSO-Spec Forged Pistons: For clients seeking the ultimate solution, CSO forged pistons exceed OE strength and design standards while remaining weight-matched for proper flat-plane crank balance. Strength without balance is not an upgrade. These pistons deliver both.

➡️ CSO-Spec Cylinder Sleeves: At high horsepower levels, factory cylinder sleeves become a limiting factor. CSO sleeves are engineered to handle extreme output and are significantly stronger than OE and far beyond the few manufacturers simply duplicating factory designs.

➡️ CSO Head and Main Studs / Bolts: CSO fasteners are specifically designed to work within the structural limitations of the OE block and ladder frame. Using improperly engineered hardware risks thread failure, distorted bearing housings, and irreversible block damage.

Our commitment is simple, to be the best, not the cheapest. The choice is yours.

➡️ This past weekend, we had the opportunity to attend the inaugural Wheaton Concours, and it did not disappoint!

Some of the most incredible cars in the world came together for an unforgettable celebration of automotive design, history, and performance. The race winning $65M McLaren F1 GTR featuring the "Gulf" livery that was actually driven to the show was obviously the fan favorite. There were other timeless classics to super cars to modern hyper cars, every corner offered something special.

👍 Congratulations to everyone who helped bring this incredible event to life for a great cause. This show benefits Special Olympics Illinois, and local Special Olympics athletes voted on and presented a trophy of their own on the field. We’re proud to have been a sponsor of its first year and can’t wait to see what’s ahead for the Wheaton Concours!

⚪ It's delivery day! Blade Silver isn’t a color you see every day. This uniquely spec’d example of a 2019 McLaren 570S recently visited Cannonball Garage for some important maintenance and diagnostics.

CBG Technician Mark performed:

✅ CSO spark plug replacement
✅ Check-engine-light diagnostics
✅ Oil and filter service
✅ McLaren oil pump replacement

From tracking down warning lights to addressing critical oil-system components, every service was completed with the platform-specific knowledge and attention to detail these cars demand.

📈 Another McLaren headed home after a major Cannonball Garage build with 920 WHP and 785 ft/lbs of torque!

This 720S came to us from Pennsylvania with a catastrophic engine failure. The customer opted to start fresh with a brand-new engine, and we were able to source it at a much better price than typical dealer pricing, saving him a significant amount of money on the overall build.

➡️ Before the new engine went back into the car, the owner had us tear it down and build it with our CSO Spec-T engine package, upgrading it with our CSO internals before reassembly. It also came to us with upgraded Pure 1200 turbos already installed, giving the build a strong foundation. After custom dyno tuning with M-Engineering, it made about 920 wheel horsepower and 785 ft/lbs of torque on 93 octane.

Yesterday, we had a delivery day headed back to Tennessee. Today, Pennsylvania. That is the reality of Cannonball Garage. Clients ship us cars from all over the country because they trust our team, our process, and our experience with the McLaren platform.

📱Whether your McLaren needs diagnostics, service, an engine rebuild, or a full CSO build, call the shop or send us a message. Let’s build it the right way.

🔁 It is always great having a return client back at Cannonball Garage.

This time, they brought in their Lamborghini Gallardo Performante for service, and it is hard not to appreciate just how special this car is. Lightweight, sharp, open-top, all-wheel drive, and powered by that iconic Lamborghini V10, the Performante brings a completely different kind of energy into the shop.

➡️ While McLarens are what we are best known for, our team also services and supports a range of high-performance exotic vehicles. Whether it is routine maintenance, inspections, diagnostics, or performance work, the goal is always the same: take care of the car the right way and give the owner confidence every time they get behind the wheel.

Thank you to our client for continuing to trust Cannonball Garage with such an incredible machine.

📱If your exotic is due for service, inspection, or maintenance, call the shop or send us a message. Let’s keep it ready for the road.
