Horsepower sells car, Torque wins races.

[@nagyandras8857]

Horsepower allways wins. No mather what.

[@dukecraig2402]

@@nagyandras8857 That's right, horsepower is the final say in the matter, torque is a component of horsepower and simply a part of the math involved in measuring horsepower. What people don't get is that there's no time constraint on measuring torque, you can take as long as you want to make 80 ft lbs of torque, but horsepower is a measurement of how much time it took you to make that amount of torque, the higher the horsepower the faster you produced the 80 ft lbs of torque. 80 ft lbs of torque at 1,000 RPM's is going to lose against 60 ft lbs of torque at 5,000 RPM's every day of the week and twice on Sunday. 80 ft lbs@1000 RPM's=15.23 HP. 60 ft lbs@5000 RPM's=57.12 HP. He who crosses the finish line in the least amount of time wins therefore horsepower is the final say in the matter.

Man, if I still had my 1991 Talon TSI AWD 5-Speed, the BEST of the DSM Turbo Trio Coupes - with her SEXY Flat wing and the BEST looking body kit and style by a HUGE margin - which was VERY hooked up, Big 16G Turbo, boost controller that I set to 21-24 PSI when using 93+ Octane, and 18.5 for standard gas - full 3" Exhaust from the manifold back - my tuner/mechanic gave me a HOLLOW Cat! And cause she was a 91, she did not ever have to pass CARB/SMOG testing - of course bigger front mounted intercooler, 750cc injectors - top end rebuild with 1mm oversized valves titanium valves and springs, and cams with a SLIGTLY aggressive profile - halfway between stock and straight track cams, Anyway - when working properly she HAD to be putting damned near ~320+ to the wheels! BUT I REALLY wish I had a Standalone ECU! MY Mechanic was able to flash my ECU as he had 5+ of the DSM trio Turbo Coupes, that he had hooked up himself. And apparently there WERE good ECU Tunes available for my setup, that took into account the higher CFM Turbo with higher boost, more aggressive cams and just higher flow everything. But the Throttle response and peak power would have been FAR Higher with a well Tuned AEM (Back in the day, I was looking at a brand called Apexi that most DSM tuners used at the time) Like the low end throttle response was a bit underwhelming, but as soon as I floored it, well I was able to ALMOST bottom out the rear shocks whilst chirping the front wheels a lot with a hard launch! I wish I could find the picture a friend took when I did a hard launch - you could see the rear was all but bottomed, and the front tires had a small gap under them with the shocks extended fully! The Big 16G STILL TODAY - remains the BEST STREETABLE TURBO FOR DSM CARS! Not even Garret has a better solution for EVO or Talon that is not massive and takes forever to spin up! People USED to think the Mitsubishi 18G or "Frankenstein" 19c were better for street use - but WRONG! The 19c would spool a bit faster, but it was HEAVILY limited in max RPM and therefore CFM -cause Turbo's are DEFINED by the CFM they can flow mostly - because almost ANY Turbo can DO ~50 PSI of boost - depending on engine size to an extent, but they will be limited in how much raw AIR they can flow! Anyway the Big 16G has more flow than ANYTHING you can put on a 4G63T - that is below the 20G Turbo or some of the larger Garretts you could fit to the motor, and 20G and above are NOT good for street use, unless you plan to use NOS to spool your turbo to win highway duels and nigthtime drag races. I blew away countless BMW M3, a Supra, 300ZX, EVERY Honda I ran against as well as all - Camaros, Mustangs, a Ford Raptor, and more on the highway when they were TRYING to pass me! God damn I miss that car... I wish I didn't go broke and was able to afford the then ~$6000 rebuild it needed when I blew the head gasket as well as cracked a cooling jacket IIRC - it was pretty major to fix, after I had already dumped ~$15,000 into the car as a then 20 year old. I had to sell her... But god I miss that car, I do NOT miss the bills from having to replace, literally everything - but I REALLY miss how insanely fast she was, and how SEXY TALON TSI LOOKED! That FLAT Wing and the body kit + the weight savings (~200+ lbs lighter than Eclipse as there was basically no sound deadening) - made her the BEST of the DSM Trio Turbo Coupes!

Before turbo became a mainstream word around the 80s, they used to be called turbine driven superchargers or turbosuperchargers. They weren’t considered so different as we think of them today. They would have called anything that created boost a supercharger but today everyone calls the electric ones, electric turbos but they should be electric superchargers.

The Supercharger has an advantage over turbos in that it provides much better torque in the low end and still works at lower RPMs. The boost is always there because the supercharger is always working. No need to spool it up. This lead to some interesting twin-charger designs which switch between a super and a turbo on the fly.

The roots and screw compressors still play a dominant role in industry today. Any sizeable compressed air supply in a factory will be built around single or multi stage screw compressors, and roots blowers are used where large volumes of lower pressure air is needed like air supply to combustion processes or transport of powdered and granulated substances trough pipelines.

Red about this Audi electric motor driven supercharger a couple of weeks ago. They say the electric motor is able to go from 0-70 000 RPM in about 1/4 sec. Amazing, right. I can only imagine how much this thing costs. And there are 2 regular turbo's onboard. The electrical one is there to eliminate the turbo lag.

[@mickvonbornemann3824]

What the go is a turbocharger that’s connected to a engine via a variable ratio drive. So at low revs the turbocharger works as a direct drive supercharger for no turbo lag, while at high revs, not just compresses intake air but also adds power directly to the crankshaft via ‘turbo-compounding’

2024 three pre-compression cylinders and three two and a half times larger re-expansion cylinders are on a secondary shaft. Said shaft naturally produces constant torque. The torque is fed to the engine's crankshaft through a CVT. The CVT functions as both throttle and booster. Increasing the secondary shaft's relative speed increases boost. Decreasing it emulates a throttle but without vacuum losses.

I’m always a bit puzzled with this automotive terminology. I was allways taught that ”supercharging” is a general term covering all methods of artficially increasing the intake pressure, - and the equipment itself could be mechanical, exhaust turbine (or electrically) driven. And then you can differentiate accordin to compressor type also to centrifugal, roots, screw etc. So the keyword here should be ”mechanically driven”(?)

a supercharger is always a blower but a blower is not always a supercharger. 2 stroke engines that require a blower to run are naturally aspirated, not supercharged. Otherwise all 2 stroke engines would have to be considered "supercharged" as they use the bottom of the piston to pump air above the piston, replacing the second cylinder in that first 2 stroke design.
