Does anyone have a Cosmo Underdrive Crank Pulley?

I wanted to know how it has worked so far, and how it compares to an Unorthodox Racing one.

The only Cosmo stuff I see talked about in this (or the 5th gen) subforums are their intakes and short throw shifters, and most of those threads are 3+ years old...

So do you think it would be better to spend the extra cash for an Unorthodox one?

Nitrous. Arguably the best performance (potential) for the least amount of money, at least up front.

UDPs are basically worthless.

UDP dont add much but the 5 hp for $60 isnt bad. Spacers are like $200 and add on the 6th gen 10hp 12tq.

The 4th gen kit is still in the works. I have already completed my initial design and gotten around several problems, including the UIM coolant bypass and stock EGR tube fitment. I will be starting the CAD drawings within a week and hope to have a prototype sometime in Nov. It takes a LONG time to produce the CAD drawings when you don't copy the gaskets. I always based my drawings off of the actual manifolds and make sure everything is port matched! 150 R&D hours went into the VQ35DE kit and I expect this kit to be roughly the same.

Nitrous is cool and all but what I hate is once the bottle is empty so is the fun.

Ricer math for the UDP but I thought the spacers were dyno proven?

best bang for buck would be an ebay speed chip, plus 20hp for about a buck!
