Hi Guys...
For most of car enthusiast, surely they heard of turbocharger and superchager all the time. Turbocharger are more famous among car tuner compared to supercharger.
The most easier way to get more power from an engine is boost and there’s no other way around because boost is the most efficient and cost effective way to get more power out of any given engine but they do come with a price or side effects if it’s not being done properly. Without a proper parts and engine management, the newly boosted engine could be reduced to scrap steel within a week.
Talking about boost, there are only two options... The TURBOCHARGER or SUPERCHARGER. Turbocharge normally allows for higher power gains because it runs on the engine’s own exhaust gases while the supercharge runs on the pulley and a belt which has a parasitic effect on the engine’s power output.
But the turbocharger also has its own disadvantage as well. The turbo lag is one of the weeknes. The turbo setup is also unpredictable compared to the supercharger setups. By using the supercharger, the power delivery is much more smoother and more linear unlike the turbocharger where nothing happen until you hit 3000 rpm. The supercharger are also somewhat reliable because they are less prone to boost spikes.
The problem with the superchargers is that they can be difficult to install. It can be bulky esspecially for Roots and Twin-Screw type superchargers and required a bit of engineering and customization to install the pulley which needs to run the supercharger. Modern day cars normally have very cramped engine bays for space savings and wires and fuses for all the new fangled technological gizmos which makes it quite hard to fit a supercharger.
Roots and Twin-Screw type superchargers are also aren’t very efficient when high boost level are concerned. This is because the Twin-Screw rotors design is susceptible to blowback from the engine when boost levels are too high. This is not so with centrifugal superchargers.
The centrifugal supercharger is a lot like turbocharger which runs on engine driven belt and pulley which means this types of supercharger is more compact compared to Roots or Twin-Screw type supercharger and able to deliver more boost than a Roots or Twin-Screw type supercharger if needed.
A complete supercharger kit comes with extra injector, F-Con SZ piggyback ECU, all associated brackets, pulleys and belts for the supercharger, intercooler and an oil cooler. The installation might sounds easy but doesn’t mean it is quick.
After all the kit was finally installed, the base map was loaded on the ECU and everything wiil be checked to make sure everything was running properly before the car is tested on the dyno.
For example taking the Nissan 350Z or also known as a FairladyZ as the test subject. A stock 350Z produces power at 200.67bhp while 24.78kg/m for torque. After installing a HKS Dual Muffler Exhaust, the power of the car increases to 206.34bhp while the torque still remains the same. When the supercharger kit were installed, it pushed out 0.5bar of boost to the VQ35DE which churns out 270.68bhp and producing 34.05kg/m of torque. The F-Con SZ were than retuned to give a leaner fuel mixture. After a few adjusting and few more runs on the dyno, the 350Z produced power about 314.24bhp with 37.87kg/m.
The end result is a wholesome 108bhp and 12kg/m of torque increase from the HKS GT supercharger kit.. That’s really fast... Can’t wait to grab that kit...
