You peeps with big stereo's are asking for trouble, the stock alternator is week, and your going to underdrive it?
also we have electric steering no belt! so i doubt we would gain much, but keep us informed, you swayed me on the headers, maybe the pully is next? |

Well,this is the other reason why I havnt added any ICE(In Car Entertainment) to the car yet,I figured I'd get all the performance upgrades installed first,then see if I needed an alternator swap.But Ill keep you informed,I think that it will work out perfectly,C-One test all there products religously,and I trust them.

Hello,
This pulley does not underdrive, its the same diameter as OEM. Just much lighter. I currently sell these for the Honda fit. But will have one for the Yaris very soon for test fitting USDM yaris & scion. |

If its not an underdrive pulley I really can't imagine that there would be any sort of gain. Also having a non damped pulley is far from ideal.

Not sure of the formula but this also holds true for lightened flywheels and clutches: rotating mass weighs a hell-of-a-lot more than stationary mass. Somebody else around here might have some actual numbers but decreasing the pulley weight by one pound will allow the motor to spin up faster due to the fact that is has to move a lot less weight. This is especially true at the lower rpms where there is less torque/horsepower available. I don't know how noticeable the performance gain would be with just a lightened pulley since I've never installed one, but I have done an old Porsche flywheel and clutch and the accelleration gains were awesome. With some trade-offs, of course.

A lot of times when your dealing with a lightened flywheel your losing at least 10lbs. I put a UDP on my old Neon and there was minimal gains, and I would attribute any gain to the underdrive aspect.
The Neon also had 2 grooves so it stood to lose a lot more weight than a single groove setup. I just think $250 for a pulley is insane.

You could fit a pulley in the old yaris through the wheel arch, probs best to do it that way again if theres room

good to know. Maybe I'll take my stocker off and just get it lightened.

Doesnt quite work that way... by the time a machine shop sets up to lighten yours, you could just buy a brand new one.
Besides, its not like there is much to remove on a stock pulley, without effecting its strength. Aftermarket pulleys are not lightned stock pulleys FYI. |
