Alta has their original s/c pulley on sale for $100 and their version 2.0 costs around $140.

My question is:

Is it worth spending the extra $40 to get the 2.0 or will the original design suffice?

 

I've had my version 1.0 pulley on for 32,000 trouble free miles. For me it wouldn't be worth $40 more for a pulley that does the same thing as the lower cost original. Just my .02 here.

 

I've got V2.0 as the price was the same. For $40 (a 40% premium! ) I'd take the V1

 

It will suffice

 

As I know V2 is better because it prevent from jumping

 

I'd go w/ version 1 again. I've had mine on for over 142,000 miles now.

I actually prefer installing the V1, as one of the collar clamping bolts on the V2 is very hard to get a torque wrench onto to tighten it properly. And I've installed several each of both the V1 and V2, as well as the Helix and M7 pulleys.

I like the idea of the V2's clamping collar with its own bolts, if you've got a damaged/scratched up supercharger shaft and are worried that the V1 or a similar design may slip, but for just replacing a factory pulley, I'll go with the V1 every day of the week, even if the V2 were the same price.

 

i have the v1 i havent had a problem with skiping jumping or anyother such nonsense.....

 

Go with the V1. save the 40 bucks for an intake or something.

 

30k miles on my v1. love it easy to install.

 

its all bling. my v1 has been beat on and ive never had an issue.

 

thanks for all the insight, i think I will be getting the v.1 asap
