I received my Crank pulley from excelerate yesterday. I hope to install it tomorrow provided that the nut is not stubborn. Does anyone have it installed yet? if so how were the gains. I am hoping to get about 10 hp out of it but that maybe asking a little too much. well ill find out tomorrow!

i am also going to be installing the exhaust tomorrow. i am going to do them at different times so i can see how the mods effect the motor.

 

nice! mine will be here next monday per UPS. can't wait! let me know how it goes man! good luck!

 

I'm not sure about those underdrive pullies. I've never installed one or driven a car with one but I cannot imagine how an alternator or a power steering pump can operate the same at idle when there is the most load on an engine when turning- and when the alternator would create the least amount of electricity.. Tell me if you notice any differences.

 

the UR pulley doesn't underdrive by much... like 10-20% i think... but it's considerably lighter

 

definently looking forward to how you guys feel about UR pulleys...

 

same!

 

i tried to get the bolt off yesterday and had no luck by my self. I had a 3 ft breaker bar and could not get it off. that thing is on there man!. I am a decent size kid and had a breaker bar and everything. i think i need to use a lift and get a bigger breaker bar. hopefully that will work. i will keep you guys updated.

As for the exhaust, that is one and all I have to say is that it was the easiest exhaust swap I have ever done. The gains were noticable especially on the highway when I downshift to a lower gear you feel it on the but dyno. I can t wait to get that pulley on to see what that does.

 

did u end up swapping the Comptech RSB?

 

no, I found out that my bro already ordered it for my Christmas present so I didnt want to do it.
