MRZ pulley***look here if you have

[Cobalt Tom]

Looking at getting the MRZ set, not sure if I should get the UDP crank or not though. Opinions?

no, your alt would hate you cause of your subs, do stock size just lightweight

My alt hates me as it is lol, and in reality if I get a UDP isnt that going to make the alt spin faster (increasing power output and shortening its lifespan)? Or will it be the other way around and spin slower? I never was good at figuring out things like that.

Nope, cars have voltage regulators, ur alt puts out gobs of power. Most put out enough to **** everything up. So spinning faster do much bc the regulator will still allow only the same amount of aperage...good for rev'n faster though

Right I get that part, and in thinking about it a little more, a UDP on the crank is going to make the alt spin slower by default. How many amps does the stock one put out? 140?

even the mrz site says that if you run an aftermarket stereo system then do not get the udp

I musta missed that one lol
