Not sure if i can say since i dont have a Ra but i have 180k on motor with a RRM Udp and have had it since 90k .

Car has never had any issues and it has been turbo for about 30k miles .

 

If you decide to replace the udp you will need a different size serpentine belt, a smaller one. You'll have to try and see which one it fits.

 

180,000 miles on mine.

 

Awesome, thats all I wanted to know. I've only got 58,000 miles and only drive it from april to october. The only other question is, do i need to reset my ECU after installing?

 

Rrm supplies the nessecary belt with their pulley so you'll be set

 

I dont recall us resetting the battery when we did mine

 

^^^
There is no need to .

 

what pulleys are you looking at

 

so its not one of those mods where it needs to relearn the new part? I can just install it and drive, or should i drive normal for a certain # of miles?

 

RRM Underdrive Pulley

 

no need to reset. you can just drive

i have about 70k miles on mine and no issues directly related to the udp so far. all issues are of the cause of my asshat driving

 

should you let it break in first before wot? And where should you file on the new one for the timing mark?

 

oh and when u go to remove the bolts, to prevent it from rotating and off setting timing, i saw in a different thread that otter said to have someone sit in the car and apply the brake to stop it from turning. does it need to be running or will it do it shut off as well?

 

^ if the engine is running, and you attempt to remove the bolts on the pulley, i think you may find your having a hard time. just a feeling, you know? kinda like trying to spread butter on bread while its in the toaster.

when I installed the udp i also had to have someone sit in the car and push on the brake, otherwise you cant get the bolts lose cause the pulley will just spin with the ratchet.

 

I think I'm the stupidest person on the forum lol, I have no idea why i asked if it needs to be running.
