Also, the engine is a lot less harsh at the higher RPMS since I added my stillen exhaust and intake.

You and I have the UD pulley though. Phimosis' skepticism is directed at the lightweight pulley from Stillen that's stock diameter, not the one we have.

PS.... The reason I am taking such a critical eye on this issue is that I really want to put a lightweight pulley on my Z..... I'll do just about anything to make it faster and it already has a plethora of Stillen parts on it. I just want to make sure I understand the risk/benefit ratio on each piece before I take the plunge.

You're absolutely correct.. I should have been more clear.

The stock pulley is balanced via the removal of material, but is not a harmonic balancer.. please forgive my mistake. But no where near as precise as a billet cut CNC'd piece, hence the NVH ring in the center. You couldn't have it be just the pure cast piece with slag hanging off different areas.

so to simplify all this stuff for newbs like me. if i get the lightweight one, WILL IT HURT ANYTHING?

Curious on why lightweight vs. U/D for you Phimosis?

(and thank you for your orders.. you're practically a rolling STILLEN billboard!)

I kinda am too, long term, but given the cost and complexity of the SC install, it's not like it would be a big deal to swap the pulley at the same time.

quick question, is it possible to get both the underdrive pulley and lightweight pulley installed on the car?

RCZ · 05-29-2009, 04:56 PM

I still havent installed mine, I may swap it with a UD one.

Josh@STILLEN · 05-29-2009, 06:22 PM

So am I! You have no idea. I get to see the progress and can't talk about it..

semtex · 05-29-2009, 07:02 PM

Aw...sure you can, Josh. We'll be discreet, won't we guys?

Josh@STILLEN · 05-29-2009, 07:27 PM

I'm not saying that some lucky owners that came by picking up product and got the tour haven't seen our progress.. but they signed a release to give up their car if they spoke about it to the forums..

By the way, I was looking at the light-weight pullie, (not the ud pullie) and was wondering if you're seeing about 8-10HP from the crank or to the ground. I'd be uber impressed (and probably still skeptic) if it were to the ground.

BTW, hate to dig up a dead horse to kick, but have you seen then RST-V8 putting out 500BHP? 2.4L weighs 90Kg dressed! Talk about power-to-weight! <-- I'd take one of these over a plastic motor any day.
