>>14218649 Personally I think its best if you fill a tank with compressed air and hook that up to the intake. No fancy mechanical shit to fail, and no messing around with air conditioning for your engine.
>>14218696 I was thinking this could be a way to store scavenged energy without needing an electrical system, but then I realized that an 80 gallon tank at 150 psi would hold roughly the same air that an M3's turbo pushes in 12 seconds.
Twin scroll turbos make the most power, keep peak boost/torque from 2k to red line, have nearly no lag compared to the old turbos. Far more fuel efficient. They also keep boost longer when off the throttle now.
No matter what type of supercharger you're using you will get parasitic loss, some types of superchargers only make boost at peak engine torque, twinscrew keep boost at idle at the cost of lowered overall gain.
There's no reason to choose a supercharger over a modern turbo, except for cost, and build complexity. UNLESS, you have a very high compression engine in such cases it might be more usable over the very wide power band (but at the cost of less power than a turbo)
What nonsense. How can you pull absolute random figures regarding when a turbocharger will spool and to when it will deliver peak power? Is this on a 1.1 litre three pot or a 10.5 eight? If engines are that alike in your mind you must change this thinking.
Flying the complete other way from your post, I have a number of turbocharged engines. One has a single scroll turbocharger, the other a twin scroll. One config makes peak torque at 1800 and full boost by 1500, the other makes peak torque at 5400 with full boost by 4500, with this turbocharger being twin scroll.
A twin scroll exhaust housing is not a magic pill that turns any turbocharger on any motor into one that 'has nearly no lag compared to the old turbos.' While ball bearing turbochargers and twin scroll housings and quick spool valves all assist in reducing the time to spool it is primarily the aspect ratio of the exhaust housing and secondarily the ratio between compressor wheel mass and exhaust wheel mass that determines time to spool. A twin scroll housing in fact becomes a restriction when used on any motor where the exhaust valve open order does not alternate evenly between inlets on the turbine housing.
Plenty of reasons to choose a supercharger over a modern turbo. Of course there are greater parasitic losses due to the direct drive, and the heat a roots type blower adds to the intake charge.
I've driven and owned and even built some freaky shit. But nothing plants you in the chair and slaps you around the face like a big blower. My god.
Usually a blown motor will have a lower compression ratio than one built for turbocharging. Blowers add a lot of fuel and air to the motor during low rpm high load situations which are traditionally bad areas for detonation to occur. Detonation with a blower combo is very violent and must be avoided. My blower combo was 8.5:1. A close friend's is a deeper 7.5:1. I wouldn't let a blower even look at an engine with high compression.
That 6V53TIB is a 2-stroke diesel. It needs that blower to live!
But seriously, they don't aspirate at all. 2 stroke diesels need pressurised air in the scavenge air space to blow out exhaust gasses when both the exhaust valve and transfer port are open. Without the blower pressurising the scavenge air space the engine will just crank over and spew smoke from every orifice.
Very low pressure levels involved from the blower, just enough to keep the scavenging process happening. All the 'boost' comes from the added turbocharger which is feeding the blower.
As an interesting aside point, the B in TIB stands for Bypass. So this model can bypass the blower once the turbocharger has spooled for greater power and efficiency.
Though I am American and love superchargers, turbos are objectively better. But obviously both combined are the best option. All of the benefits and none of the downsides if you have enough engine bay space. Plus any idiot can install a custom turbo setup but a supercharger ususally requires a kit
Turbo is better. Supes are parasitic. They use power to make power. Turbos are powered by exhaust fumes. More efficient system that can actually improve both performance and mileage. Setup is everything of course. A well tuned supe is better than a laggy as fuck turbo.
Also supes have better delivery and can augment a turbo, but twin turbo does that better.
