my point was turbos have alot of little tiny parts, in my exprience turbos tend to die. They usually last 3 to 5 years and its time for a new one. That might be because they are pushed but superchargers are out of common use, they are extremely expensive and require alot of knowledge to pick your gearing. Where as now a days the turbo is pretty much picked for your engine. Plus they are cheap at about 2500 to 3500 a piece. They were originally designed for diesels and are somewhat over rated. A roots type supercharger is the most simple of the three but the most commonly used. This is your low powercharger and tends to not do a whole lot, a centrifugal is a little bit better but gets hotter than the roots at quicker pace. If you hang with alot of older cars you will see more of the superchargers. They can be extremely quick and are commonly used in drag racing on 8 second cars. Most 4 cylinders do not use them because they require more money for the initial purchase and most that are made would give a 2.5L engine an ass kicking. Most wont even fit my car, and I am an 8 cylinder. For example to see a 6-71 on a 2.0 honda would be a joke, but to see it on a 383 would be quite common, the 383 make mores than 30 ft lbs of torque at the crank N/A, (sorry had to do it) and has the capability to run it with actual power gains. |
