Came across this video where they stat that turbo and super charging is not reliable.
But Volvo makes reliable cars with this setup....don't they?
 
anything thats more complicated is more prone to issues especially with new tech. forced induction has been around but requires more upkeep + as usual the quality of said part can be the difference! $$$ is always a factor as we only see a few using both types of injection that is more $$ + VW uses it more in euro because of tighter emissions.
 
Detroit made supercharged and turbo charged engines that did pretty good and made good power.
 
haven't watched the video, but Nissan Did this in 1988. (pr something similar.)
March* Super Turbo. only built 10k of them, JDM only of course. *March is the JDM model name for the Micra

https://en.wikipedia.org/wiki/Nissan_Micra#Super_Turbo
"In 1988, Nissan launched a limited 10,000-unit run of its homologated (certified) Nissan 1989 Micra Super Turbo (EK10GFR/GAR). Both this and the 1988 Micra R (EK10FR) featured the same highly advanced sequential compound charged (supercharger plus turbocharger) engine in an all-aluminium straight-four 930 cc eight-valve MA09ERT unit that produced 110 PS (81 kW; 108 hp) at 6400 rpm. This car came with either a 3-speed automatic or 5-speed manual gearbox with viscous limited slip differential, as well as options such as air conditioning and electric mirrors. The Micra Super Turbo still holds the crown for the fastest production Micra in Nissan's history, with factory performance figures of 7.7 seconds to go from 0 to 100 km/h (62 mph) and 15.5 seconds to run a quarter-mile. It has a top speed of 180 km/h (112 mph)."


Supercharger for down low (while the Turbo Spools), and a special diverter valve to dump the supercharger's boost once the Turbo starts making enough boost.

a quick google of "March Super Turbo" will Bring up the Videos Mighty Car Mods has done on them. (Marty's owned 2. one years ago, that he sold, and a couple Christmas's ago they went to Japan and Bought another, which he plans to keep "Forever")
 
More parts is often less reliable. But it really comes down to the engineering. Did they design for maximum umph or with long term reliability? or something between?

Latest Volvos do pretty good on the supercharged and turbocharged system. I especially love to XC90 that is Turbocharged, Supercharged, and a Hybrid. With that being said - engines got issues with low tension piston rings. Don't think it's related to the forced induction, but worth mentioning, before everyone snaps their necks rushing to buy the latest super-turbo-hybrid Volvo just to find out it swallows oil at 1qt/1000mi rate.
 
I'm curious how the Volvo twin charged units will hold up over time/miles - they are very complex and high strung with their output per liter. Had a V90XC T6 rental with the twin charged and it definitely moved that tank quite nicely - 300ish HP out of 2 liters. Volvo was able to make it not sound like a 4 cylinder, it had a nice growl under WOT.
 
...and there are guys that have done it.

This is Alexis blown and turbo'd mill he's got in his boat.

Its incredible.

the only way to describe it is like having a rheostat on the side of a nuke plant connected to your powertrain.

It redefines the meaning of the words "poweband" and "throttle reponse".

A weekend setting on inexpensive fuel is usually around 1500HP. More than enough to scare your friends.

Turn it all up and run the right fuel and the half dozen or so of these of these that have been made will put around 4000HP into whatever is on the back of the crankshaft.
