It's most likely cheaper to go through an UR distributor rather than direct from UR. Stillen is just one of their distributors. Shop around!

You should feel more torque in low and mid range rpms.

 

What's your current price on the UDP for the 2K Max?

 

I gotta check on my pricing, but it's probably going to be priced around $169

 

I read in another post that the pulley acts as a vibration damper. If the crankshaft is even slightly unbalanced, reducing the weight on the pulley could cause the crankshaft to break. Has anyone ever heard of this happening on a Maxima?

 

If you guys frequent the Z forum (www.twinturbo.net) then you would know I'm not a big fan of the underdrive pulleys. yeah, it's a great bang for the buck but long term reliability is still an issue. I don't like the idea of swapping out a big, heavy stock pulley and putting in a lighter one. The vibes/frequencies from the accessory belts travels through the pulley into the crank. the VG30DE/TT (Z32 engines) are also internally balanced on the crank, so most *should* be fine, but they're risking an $7000-8000+ engine for 12-15 rwhp. Not worth throwing a rod if you ask me. I still sell them if the customer *really* wants it.

 

I must say I don't like the sound of that at all, Phuong. Point taken.
