When I install my Aluminum rrm crank pulley into my 2002 lancer oz rally do I need to change the belt or anything or do i just replace it with my old one and I'm good to go? Any help would be very appreciated.

 

you dont have to do anything but jus swap em out, it took literally 20 minutes

 

could you tell a difference after the installation?

 

there was some difference, but im an auto so... i dont have much throttle period haha

 

Auto guys feel a little response but we have little "control" over our cars throttle response. Manual guys may have better results

 

i could feel a difference being manual. it defiantely got the engine working quicker. the rrm one is i believe 1 lbs or material compared to the stocker which is about 4-5 lbs.

 

Yes sir, less weight causes the pulley to spin faster

 

Alright thanks. Yea I just bought the pulley from rrm a few minutes ago. ive got an auto myself but I mean it defiantly wont hurt me getting a lighter pulley. NExt mod... Piggy back. What do you guys think about that? WOrth the money or nah?

 

yah just get a piggy if you're new to tuning.

 

It does not spin faster.
It is lightweight, so there is less load on the crankshaft and less force required to turn the pulley.
You'll notice it revs a little faster.

ECUflash all the way. The days of the piggyback have been over.

 

hey guys im having a real problem right now. When i try to take off the crank pulley bolt it wont break loose. I have a 300lb torque impact gun and thats not doing it. Any suggestion? Im not sure what the problem is.

 

this should help ya https://www.evolutionm.net/forums/la...ley-04-es.html

 

or you can do the old school method lol. socket breaker bar. find a nice spot for it to lay on and isnt gonna move. have someone hold it and turn the key once starter will loosen it quick. done it to 20 cars lol n never a problem.


edit: i just read the link haha. just like me...

 

Oh ya 300 wont do it my friend. The crank pulley is one of the tightest bolts on a car. I got tired of fighting with them a while back and bought myself a nice pneumatic impact with 710 Ibs of torque and some 1/2" air line. It either breaks it loose or just plain breaks it havent found anything yet that can stop it.

 

You need a bigger gun.
