Crank pulley... not anymore - Toyota Nation Forum : Toyota Car and Truck Forums

I've been searching for a crank pulley for my v6 camry for a while now, i couldn't find anything or anyone who would custom-make it for me

i contacted URD asking if they can make me one, but they said that they used to do it but it was slow-moving so they decided to cancel its line!

does anyone know where i can get me a custom crank pulley? i've been searching for a month now

And talk to "TRD4LIFE" he had a V6 Camry with an upgraded pulley.

why do you want a lightweight/underdrive pulley? ... i suggest you search the entire forums for some info on why NOT to get one

what's the down side?!
i want one with the same diameter as the stock one, only lighter...
unorthodox site says that about 80% of the power comes from the weight reduction and only 20% from the smaller diameter...
so if i get one with the same diameter as the stock's, i should get the hp i want without compromising anything else, right?

i heard horrific things about after market UD pulleys as well. the extra weight is used to balance and steady the crank shaft. without the weight, then the bearings take much more stress and fail prematurely.

theoretically yes, but to what degree does this affect the bearings?
i had a friend with a nissan maxima, he had a chinese-made crank pulley with crappy quality... it has been two years now since he got it and nothing's wrong...

even if the bearings life span is reduced by, lets say, 30%, it's not that bad, you get something around 13whp from these things, that's alotta power for $200 at most.
