Lightweight flywheel and lightweight pulleys: bad? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I actually have the TRD lightweight flywheel, and it's the best mod I fitted to my car.
What if I put lightweight pulleys? Any issues?

Lol. You know this kind of topic how it ends up ...

You won't notice a power increase really. If you just want to have the car rev in neutral quickly, it will accomplish that

Leave the pulleys alone, not enough delta in angular momentum to make a difference. Changing flywheel on the other hand makes a noticeable difference in both free rev as well as acceleration 8n lower gears.

Put the stock pulley back on after having my car for 5 years now.
ZERO difference.

Idle to redline and redline back to idle with the lightweight pully and the stocker were less than half a second different.

BUT The car did have that pulley from 6 months after purchase until a month ago. (2013MY)
No unusual wear to the engine according to OA.

IMHO pulleys are 99.99999999% bling and nothing else.

A pulley gets you exactly as much HP back as the drag reduction from a good wash and wax. The real gains are in the smiles per gallon the next couple days knowing what you did.

Waste of money. I still have mines in a box... Bought it before reading up on them in the forums. Wanna buy em? Lol

Ok. Here is now my reply. I have Toda's light flywheel and pulley kit. No issues at all after 3 years of usage. As others said, the pulleys will not give anything. Only if they under-drive peripherals like the water pump or battery generator, but again the gains are small. It was calculated at the past to be in the range of 1-2 hp. The flywheel is a different story.
