Superchargers for Commodores and HSVs: An Exciting Performance Upgrade
For years, superchargers have been a popular upgrade for Commodores and HSVs. However, the Gen F GTS release, featuring a factory-installed supercharger, catapulted their popularity as an aftermarket enhancement. These performance boosters are now essential for those seeking to elevate their driving experience.
What Are Supercharged Commodores Like to Drive?
Superchargers using the latest top-mount technology can dramatically enhance performance while preserving the car’s luxurious feel. The latest systems, like Harrop and Magnuson, run quietly when cruising. You will only hear a noticeable whine when you apply full throttle. This sound complements the engine without overwhelming it.
When correctly tuned, these superchargers deliver smoother, more effortless acceleration at low RPM. For example, the car feels much lighter when cruising at 2000 RPM in 6th gear. It is almost like it has lost hundreds of kilograms. At wide-open throttle, even at 4000 RPM, the acceleration is amazing. You need not push the engine into higher RPMs to feel that thrilling “push-in-the-back” sensation.
These superchargers and a full-performance exhaust upgrade can produce 460 to 510 engine kW. This output translates to about 350–400 rwkW. This ensures thrilling acceleration and exhilarating performance at full throttle.
Front-Mount Superchargers: A Different Experience
Front-mount superchargers, such as Prochargers and Vortechs, offer a unique driving experience. Unlike top-mount systems, they build boost progressively with RPM, achieving peak boost at high revs. However, they often provide low amounts of boost at lower RPM. This means the extra power is not felt until 4000 RPM or higher.
Front-mount systems can be louder, especially when the engine is idling. However, they work effectively when the engine can handle high boost levels. This capability provides linear, predictable power delivery, which is ideal for high-RPM performance.
Front-mount superchargers are better at reducing tyre spin than turbocharged systems. Turbochargers often deliver torque in sudden bursts.
Recommendations for VE and VF Commodores and HSVs
If you upgrade a VE, VF Commodore, or HSV, we suggest the Harrop FDFI2300 TVS2300 or the Magnuson Heartbeat 2300. Your choice should depend on your aesthetic preferences. Both systems deliver exceptional performance and maintain high quality.
On a stock Commodore L77, these systems can achieve up to 460 engine kW (approximately 345 rwkW in autos or 365 rwkW in manuals). For HSV LS3 models, they reach nearly 500 engine kW. This is about 375 rwkW in automatic versions and close to 400 rwkW in manual versions.
For near-new cars, we offer the Harrop FDFI2300 installation for $16,600, which includes fitting and hub dyno tuning. The Magnuson Heartbeat 2300 is also available at a slightly higher price.
Cam Upgrade and Supercharger
It is best to combine a cam upgrade with a supercharger either do the cam before or during the supercharger install. With Harrop FDFI2300 systems and cam upgrade combined we often see near 500 rwkw.
Exploring Advanced Options: FDFI2650 and Beyond
We also provide the Harrop FDFI2650 TVS2650, Magnuson 2650, or Whipple 2.9L for enthusiasts seeking even more power. Combined with cam upgrades and full-performance exhausts, these superchargers can quickly push output to 500 rwkW or beyond. For those chasing the upper limits of performance, 750 rwkW (1000 rear wheel horsepower) or more is achievable.
However, it’s crucial to note that factory cylinder sleeves are prone to cracking at higher power levels. To solve this, we can strengthen your engine block with high-quality sleeves. We will also use forged pistons and rods. This will ensure durability, even at high power levels.
Performance Essentials and Alternatives
For VE Series I models, a fuel pump upgrade is necessary to support the supercharger. We typically recommend a 1000hp fuel pump kit, which costs approximately $2,300 to install.
Additionally, a performance exhaust is vital for maximizing power gains. High-performance setups benefit from 2-inch primary headers, ceramic coating, 100-cell catalytic converters, and twin 3-inch cat-back systems.
If supercharging exceeds your budget, consider a camshaft upgrade. This option can boost output to 430 engine kW or more when paired with quality cylinder heads. Starting at $4,850, a cam upgrade includes new lifters and provides that choppy, aggressive, idle sound many enthusiasts love.
Upgrading the LSA Supercharger
For vehicles with an LSA engine, upgrading to the Harrop H2650i is a better choice than maxing out the stock LSA1900. In our testing, the H2650i consistently delivers over 50 rwkW more at the same boost level, with additional spark advance. This upgrade not only increases power but also enhances efficiency and reliability.
