I've tried three different versions of the Granatelli COPs and they all started off great and eventually failed. Stick with the stockers, or at least do a lot of homework before you buy an aftermarket set. I can tell you this much, Modaddict is making over 700rwhp... on the stock COPs.

 

He speaks the truth... COPs will eventually fail other than the stock ones. Aslong as you know that it usually happends after about a year of use and you are okay with that, then i think they are worth it.

Heres a dyno graph of a saleen s/c back to back runs. One is with stock cop and then the next they just switched out with the WEAPON x cop no tuning changes or anything were made.

 

I've heard great things about the 2V weapon x but damn, the 3V's have been in production for over a year!

When are they supposed to hit the market? I'll wait if it's soon...

 

last i heard they were starting mass production on them this week, so i figure they will start being sold next week? Not really sure when a product is sold after production has begun.

 

I should have said (meant) R&D not production. I may just have to wait on those!
