Overview: supercharger vs. turbocharger

Nissan March use Supercharger and Turbocharger
Engine MA-10 1.0L 1998 SOHC less than 100hp

I'd have to agree with texan's comment in/re reliability - it depends on the overall design of the engine / ___charger system.

An example - nearly every semi truck on the road is turbocharged., and the engines in these vehicles go many times as far as the engines in most of our cars.

That said, it seems to me that for a given engine, having lower BMEP (perhaps as a result of having lower/no boost) is bound to reduce wear @ nearly every interface in the engine. The ring/liner and skirt/liner interfaces in particular, followed by the interfaces on the exhaust side of the valvetrain, then the conrod bearings and crank bearings, etc... Torsional vibration magnitudes in the crankshaft will also likely be reduced (due to lower excitation magnitudes), which will probably not affect crank life (crank should be designed to accomodate TVs anyway) but may improve the longevity of the TV damper. I'm not sure, off the top of my head, how a reduction in boost will affect load-line variation in the journal bearings in any given engine, so I'll refrain from commenting on that.

Actually PP, Nissan's March SuperTurbo engine (MA09ERT) was 930cc and produced 110PS at 6400rpm and 13.3kgm of torque at 4800rpm. As far as I know, no other manufacturer has made an engine that small in displacement this powerful!

Can you put a supercharger and a turbocharger in the same engine?

[ivymike1031]

yep.

texan or neone who has a good idea of what they r talkinh about on a type r i heard b16b civic type r engine are more for all motor so what would i do plus supercharge it or turbo it?

[texan]

I'm not exactly sure what you're asking, but if you have a B16B and are interested in forced induction, a mild turbo setup will work best. That engine isn't built for turbocharged use so the boost must be kept to a minimum, but a properly designed and installed turbo setup will be very effective on that motor.

[typerdelsol]

well what do i have to do to have an all motor car? And turbo i was thinking to do a little more research on top fuels civic type r it is japans fastest fwd car they are using a blitz k3t turbo, e56 waste gate, and a 3 row intercooler what do u all think ???

[typerdelsol]

n e one here have a ctr engine and vafc on it please give me your specs if neone can help

First off, loved the thread on Turbo vs. Super chargers.

Next I have an interesting spin ...

Why don't we have an electronically controlled blower mounted on intake and/or exhaust that will spin up based on a combination of throttle position and engine speed and provide continuous stable boost throughout the rev range?

It would seem to give the best of both worlds ...
1) no turbo lag since it can be made available at the same time the fuel injection system adds the fuel.
2) no supercharger power bleed since we are powered by alternator / battery.

This moves to a new level when you consider a hybrid engine like Toyota Prius. Electronically supercharge this and the power will come from the batteries that were charged by inertia.

[texan]

The problem with your idea is that, thus far, nobody's been able to build a supercharger capable of producing meaningful amounts of boost (especially for a sustained amount of time) using the vehicle's electrical system. Visteon did develop a system designed for short use boost, but it's a fairly large revamp of the entire electrical system from what I remember. Once carmakers finally jump to 42 volt vehicles it will be much easier to accomplish, but until then the promise of electrically driven boost seems a little out of reach.

That's why I mentioned the Prius, it has a normal 12v system plus the 201v system that runs the electric motor. It would seem like this could be used to get a lot more 'on-demand' power out of a small enigine.

I can certainly see your logic, but from a manufacturer's perspective I'm still not sure it's the best option. After all, whatever they develop will need to be a technology that really improves upon something other than just power output, as that's easy enough to do already. The hybrid systems currently in production make large strides in coupling extremely low emmissions and high fuel economy with respectable power output; your idea would have the power output dealt with but wouldn't adress the emmissions or fuel economy as effectively as an electric booster motor. You'd work just as hard to generate and store the electricity as the other guys, but then you'd waste most of it by converting it back into mechanical energy, then to airflow, then to heat energy (of which only about 1/3 is used to twist the crank), and finally back to mechanical energy. That's a very lossy method, which is why the systems coming out avoid this IMO.

for V8's and other large displacement motors would there be any advantages to install a turbocharger as oppose to a supercharger for drag racing? And what about installing both a supercharger and a turbocharger, what would be the advantages to installing both as oppose to just one?
