We just released the New MRZ Lightweight Crank Pulleys

Same diameter as OEM to keep boost level constant, but 2.5 times lighter than the OEM cast iron GM pulley! this pulley will help free up extra HP from your engine with this huge saving on the crank rotational mass. This is one of the bang for the buck modification you can add to your engine and it's also easy to install in 30-45 minutes depending on your mechanical skills.


OEM WEIGHT: 1830 Grams


MRZ WEIGHT : 730 Grams


2.5 lighter than OEM ! Now that's a radical drop on the rotational mass of your crankshaft meaning your engine will get to revs faster.

Just to show the Blue and Red

 

Any other colors besides black, blue, and red? Silver/Gun metal maybe?

 

nice... price?

 

so this will fit the 2.2L? and would you gain more hp in the 2.2L than the 2.0L? and do you have any dyno numbers yet?

 

I clicked the link in the first post....

"2.0 Ecotec LSJ Supercharged LSJ Lightweight Crank Pulley[LSJ Crank Pulley] $174.95

 

says for the 2.0 LSJ, so probably not made for the 2.2

 

yea but at the bottom of the page of the link it says for 2.2l and 2.4l and i was just makin sure it fits the 2.2l. and if you would gain more hp than the 2.0

 

That's pretty sweet. Maybe in a month or two I might pick this up.

 

You can get them in silver/natural billet aluminum color also, we have some other colors we can do as custom order...

Those are for the Supercharged LSJ 2.0, they would fit the 2.2 but the 2.2 and 2.4 have 5ribs pulleys... We'll have Underdrive pulley made for the 2.0/2.4 very soon, those will be underdrive so the HP gain will be even better on those NA engines.

$174.95

 

o thats awesome well keep us updated about the 2.2l pulleys cuz i would get me one

 

siiiick

 

We'll keep potsing our new stuff over here

 

any chance of getting an alternator pulley made as well for the lsj? eventually i'll be doing a 6 rib conversion and i might as well get some hp out of it

 

whats the hp gain look like?

 

The alternator pulley are on the way also, 5 and 6 ribs

 

Are you guys going to do a "free shipping" or "group buy" deal?

 

We will get someone to compare the numbers soon on the Lightweight LSJ pulley but the HP gain should not be more than a couple HP since it's the same size as the OEM pulley, the real gain will come from the rotational mass reduction, our pulley weight 2.5 less than the OEM pulley, this will help your engine revs faster since the rotational mass is readuced

If we get 10 people or more we are ready for a group buy anytime

 

saved for the later

 

mark me down for an interested buyer, i bought the lightweight pulley for my 2.2. a couple years ago and it worked great for me

 

2.2 and 2.4 pulleys should be raedy for sale this week

They will be available in stock diameter or as UDP (smaller diameter)
