Superchargers for VE VF V8 Harrop Magnusson Whipple
There has been a range of superchargers available for the Commodores and HSV for years. The release of the Gen F GTS with its factory supercharger has recently given a boost to the popularity of superchargers as an aftermarket item.
What Are They Like To Rive?
The superchargers using the latest technology top mount systems can give a good boost in performance without spoiling the luxury feel of the cars. The newer superchargers are relatively quiet although the whine is apparent at full throttle, the sound doesn’t dominate the exhaust at cruising speeds. When tuned correctly there is much more ease of acceleration at part throttle at low rpm, eg. 2000rpm in 6th gear the car feels a few hundred kgs lighter. The acceleration at the wide open throttle is extreme at even 4000rpm, and this negates the need to get the engine into its higher rpm ranges to be enjoyable in its push in the back. Most of the new superchargers, when combined with a full exhaust upgrade, will end up with 460-510 engine kw even with the factory camshaft, that’s around 350-400 rear wheel kw, so there is plenty of reason for strong acceleration at full throttle.
What About A Front Mount Supercharger?
Front mount superchargers, eg Prochargers, and Vortecs build boost usually with rpm, so at peak revs, there is peak boost, and usually, at low rpm, there are low amounts of boost. Sometimes there is no extra shove in the back from these superchargers until 4000rpm or more. They are also usually far noisier particularly at idle than the modern top mount superchargers. They excel when combined with an engine that can cope with large amounts of boost since more boost at high rpm means the boost is consequently reaching a useful value much earlier in the rpm range and the added benefit of this is they provide very nice linear tractable power. Superchargers deliver acceleration in a way which is unlike turbo systems which usually come on so quickly with torque at low rpm that they spin the tyres more unexpectedly. A smart setup car with a top mount and matching engine is hard to beat at the strip. The new procharger with variable boost is also worth a look.
What Do You Recommend For VE or VF Commodores And HSV?
We currently recommend the Harrop FDFI2300 TVS2300 or the Magnusson Heartbeat 2300 depending on customer preference for looks. Both perform well and are high-quality items. When combined with aftermarket heads, full exhaust and a blower cam upgrade they are capable of making over 500 rwkw. On a factory Commodore L77, they are capable of 460 engine kw which is 345 rwkw in an auto or 365rwkw in a manual, in HSV LS3 this increased to near 500 engine kw which is 375 rwkw in Autos or approaching 400 rwkw in manuals.
For near new cars owners, we can now offer the Harrop FDFI2300 installed for around $16000 fitted and hub dyno tuned. It is a bit more for the Magnusson Heartbeat 2300.
We can also offer FDFI2650 TVS2650 Harrop and the Magnusson 2650 or the Whipple 2.9L. We can provide cam upgrade with SC combos which with full large performance exhaust can make 500rwkw easily if desired and as much or more than 750rwkw is possible (1000 rear wheel hp). However the factory cylinder sleeves are fragile and prone to cracking at high power levels due to core shift from factory. We can resleeve your block with better quality sleeves and build the engine with forged pistons & rods which will make the engine safer at very high power levels.
The VE Series I will also require a fuel pump upgrade to supply enough fuel for the Supercharger. We often use the 800hp kit which fitted costs an extra approx $1900. 1000hp and 1500hp fuel pump upgrades are available.
Performance Exhaust is essential to support any Supercharger Upgrade. High end power combos are best with Headers that have 2″ primaries, ceramic coated and 100 cell cats with twin 3″ catbacks.
The alternative if SC is out of your budget is you could do a cam upgrade and lift power to as much as 430 engine kw or higher with some good heads. The car will idle choppy or lumpy which may be what you want. The cost of an oztrack cam upgrade starts from $4850 with new lifters plus options. Click HERE for more details delivered via messenger.
