A positive displacement supercharger sits on top of the intake manifold (typically), and makes peak pressure at low RPM's. You can also run a narrower lobe separation angle than other forms of forced induction, but has to be weighed against the potential to have “blow through” during valve overlap. In fact, I think there were. For the uninitiated, both a turbocharger and a supercharger serve to give your vehicle a performance boost so you get more power when they’re installed in the engine. With electric superchargers, this really can be an exclusive OR, but with most forced induction you can't shut off the blower so you're either using your super/turbo by itself or you… Only once the horsepower increases rise above 20-percent, would a nitrous-specific profile be recommended. All posts copyright their original authors. ... a turbo can be … One thing with supercharged and turbocharged combinations, is that the heavily compressed intake charge loses velocity compared to a lighter, less-dense naturally aspirated charge. The combination of the negative pressure wave in the chamber and a positive wave in the runner can result in a net pressure drop across the valve at intake opening, even though the piston is still going up towards TDC.”. i know that you can take an engine and put two turbochargers on it, my question is can you take an engine and put a turbocharger and a supercharger on it? While we’ve been very general in our explanations, the reason for that is twofold. I've seen a 240 SX built as a supercharged turbo, though this example the man used it on an official Drift track. Both are air compressors, but they operate and perform very differently. You can also run a narrower lobe separation angle than other forms of forced induction, but has to be weighed against the potential to have “blow through” during valve overlap. This is because of their more straightforward installation in comparison to other forced induction choices and the amount of horsepower they add to your build. Just have to tweak the computer Turbos are more tricky. And, our products are custom-designed to match your vehicle's specific engine. The supercharged vehicle delivers power at a faster rate and while traveling at lower RPMs. They can help point you towards the right camshaft profile, whether it’s on the shelf or a custom grind. This also reduces the notable stress on the components in the lower RPM range while assisting with traction. In short, no. It pushes air into the engine, increasing its density and allowing the engine to have more oxygen-intake cycles. Because nitrous has its largest gains low in the RPM range, the common school of thought is that the camshaft profile should help balance the powerband. Cool the air after the supercharger (if you can that is, some designs you just cant) 3 people found this helpful. As others have said twincharging has been done lots, both on cars and airplanes. Superchargers will have no lag since there is no wait for the power increase. Why Do We Measure Engines Against The Power Of Horses? I'd put the extra money in suspension mods to keep it on the road with that kind of power. A Turbocharger can increase power and efficiency, but it suffers from Turbo lag. The B-17 used this very configuration in order to provide the power it needed to reach altitude. I have 14 PC turbo and 17' PC SC. Most automatics are designed to slip when they shift, which makes for a nice smooth ride but increases wear on the tranny, and the shift kit makes them a bit firmer. Turbochargers require more RPM to make peak boost, and the larger the turbo, the more exhaust it takes. The density of the intake charge is increased with the addition of gaseous nitrous oxide, as well as an additional fuel charge. Some Volvo’s use a small supercharger to boost power off the line, the turbo taking over after it spools … But where the turbo falls short is turbo lag. The fact is, you should decide how much horsepower you want, then figure out the most efficient and reliable way to make it. Mark helpful. The response is immediate, and the operating temperatures are generally cooler. A turbo is powered by exhaust gases, and a supercharger (blower) is belt driven, but the end result is pressure at the manifold, instead of vacuum. “We can use piston motion and some wave tuning to get charge motion at a lower velocity and with less valve timing,” Godbold explains. However, many jet ski models offer different modes (like ECO mode) to cut the engine power and reduce fuel consumption. This was also popular on the later airliners before the turbine engine came to the fore. I understand if some of you are laughing and thinking, "just buy an S model mini". Ask MetaFilter is a question and answer site that covers nearly any question on earth, where members help each other solve problems. We promise not to use your email address for anything but exclusive updates from the Power Automedia Network. © 2017 Power Automedia. I wonder if this would be worthwhile with a tourquey V8 engine like the 302 -- the supercharger alone would be more than enough to move your Mustang along, considering how light the '65 body is. Report. On the intake side, you have standard atmospheric pressure, but a heavier, denser intake charge that takes more effort to draw in. Mark helpful. The SC runs very consistent and has very snappy bottom end but it's hard on fuel especially if you have to run a trail for a ways to the Backcountry compared to the turbo.
