A torque converter in a manual transmission car?

At low rpm's engine can only produce so much power.
Torque converters allow engine to be spinning at higher rpm's thus producing more power, while the drivetrain is spinning at low rpm's.

Thus what you think of fitting a torque converter to a manual transmission car?

Of course the torque converter must include a clutch, both to allow smooth shifting and to provide lockup as lockup-torque converters do to prevent slippage.

isn't this the principle of the automatic clutch?

I've seen it done in stock cars before. I don't exactly understand how it works tho.

Too complex to be worth it on a street car, and the same effect can be achieved with proper clutch control.

When gearboxes had 2 or 3 gears it may have had value.
But with 5 and 6 then the gearing is doing all the torque multiplication you need to get power at the wheels and as noted, the only advantage then is during gear change and good clutch will do a better job with less weight and losses.

If it's what we think he's asking, yes, and of course it's been done in several ways.

Not really that complex, but not worth the extra weight... and the market has always been rather limited for it. More people prefer autoboxes, they're easier to control electronically and provide greater profit for manufacturers.

This, coupled to the aforementioned extra weight. IIRC at least 4 manufacturers produced models with some version of a torque converter managed clutch with 4 speeds: NSU, VW/Porsche, Renault, Hanomag... there were probably others.

Yes at Low rmp's engine can produce only so much power if you increase your rmp's then your engine power will also increase .
