Wondering if a lighter weight torque converter frees up horsepower the same as a light weight flywheel does on a manual transmission car. I would suspect it does, but have never heard it mentioned or quantified as to how much it may be worth. Many of the aftermarket converters have a smaller diameter than the stock conveter and are also significantly lighter. Anyone have any knowledge, or dynoed first with a locked stok converter and then re-dynoed (locked) after adding only a converter? If so, what brand, and model, was the converter? Thanks!

Yes it makes a difference.

Think rotational mass.

If lighter tires/rims makes a difference, then think what a verter spinning at 5000 rpm will change...

Gotta overcome the inertia, and then also think of the fluid yer slinging around inside that thing...

Also think of windage and "windage trays" for the SBC guys. They gain a lot of HP just by keeping the oil off certain spinning parts that don't need lubrication.

Hell you can even get better HP from changing from a Steele driveshaft to a Carbon Fibre one...

Pretty much what I thought. I was just curious what a lighter converter in an auto, or a lighter flywheel in an M6, buys. I suppose just a few, in either case, but it all adds up. Thanks!

yea, not necessarily gaining horse power but like you said better horsepower, or in other words a more efficient kinda horsepower

True. The engine isn't making more HP, but you are getting more HP to the wheels, so your RWHP would increase. The only exception IMO woudl be the windage tray.

I know it's a technical difference, but yer correct.
