Im at 107k miles and about to do my A14 service this or next week and I remember a while ago when I first got my 05' that a few of you had done an extra pulley for a bit more power. I though I would look into it when I was in there doing the timing belt/water pump, but now that im about to do the service, and I can't find the threads about the extra performance pulley.
Any one remember anything about this? Any help would be great

 

UR Crank Pulley, either u can get the stock size and use oem belts or go smaller & lighter one, but u will need smaller belt.
The both increase aceleration i had smaller one in my TL and i loved it. Now I have the stock size in my RL and it makes a difference cuz the RL is so heavy.
The Stock Crank Pulley weights over 7lbs. and the UR weights less the 2lbs, The smaller UR weights even less.
Less Weight = More Power.

 

Smaller pulley = underdriven charging system = more strain on your alternator

At least I think that's how it goes.

 

Yup I'd go stock size with this car

 

as others have said, PLEASE go the stock diameter light weight pulley route

 

Ditto.

 

Thanks for the wise word, Heavy!

 

 

Thanks!

 

In the next 25,000 miles I am due for a timing belt. It would be the best time to put it on.

The website is UnOrthodox Racing. The RL stock size pulley is $346.

 

go to http://www.excelerateperformance.com thats where i got mine for $200 new!!

 

I got stock sized pulley because I got a big ass sub in the trunk !
