Hey Guys, I wanted to know are MRZ Alternator Pulley worth it ? Have anyone of you experience with this pulley ? I am not gonna get MRZ Underdrive pulley, I rather not risking breaking my engine. As far as I did research alittle about MRZ Underdrive Pulley is not worth it IMO cause only alittle HP gain and just REV alittle faster. Anyways I got a good deal for MRZ Alternator Pulley but I rather wait not to buy them first and hear out an experience one that has 1.

 

Bump! Anybody ?

 

In for answers... And answers about the crank pulley! I'm thinking about both

 

Crank pulley is definitely a bad idea. It doesn't absorb vibrations as well as the stock and can cause oil leaks, plus it does basically nothing for performance. Alternator pulley I'd say probably gives the same lack of performance gain.

 

That's what I thought, I would go for Alternator Pulley instead of Underdrive Pulley. I got good deal for $60 bucks can't complain with that instead of Underdrive Pulley for about $160 bucks. I will complain with $160 bucks that will give me oil leak. LOL!

 

Still don't think that the alternator pulley is worth it, but it's your money

 

Why You don't think Alternator Pulley isn't worth it ? Have you seen the size and weight that thing ? I think it's worth it alittle cause of the weight and free up alittle bit. $60 bucks isn't that too bad compare to $160 bucks can cause oil leak.

 

the whole oil leak thing, a guy with a yellow lnf tried an aftermarket pulley and hes had no issues to report. the thread was updated maybe within the last month

 

Can you post up the link about his update ?

They re designed it

 

The link won't work. Just google mrz light weight crank pulley cobalt and go to the your cobalt threads. Some good info

 

might take me a few. ill get it to you

 

Yeah, I did look it up and it's good for LNF but for LSJ nope. That's why I rather be safe is just only get Alternator Pulley and not Crank Pulley.

 

i wouldnt waste money on an alternator pulley

 

No pulley is gonna net you much in gains (other than a smaller sc pulley obviously)
