The crank pulley is an underdrive pulley, its a 23% underdrive pulley that replaces the stock balancer/pulley in order to not just underdrive but also save on rotating weight. All others I have ever seen just bolt on top of your stocker, adding even more weight than you had stock. Like I said I wouldnt do it any other way.

Highly recommended and worth it.

Poop, i meant to say did you also do the alternator pulley

 

If you have a hypertech chip you can send that in to us to have it reflashed to save anthor $25 bucks.

Our normal price includes a memory adapter so theres no need to send us your stock chip.. those adapters cost us plenty so if you have your own chip/adapter that can be reflashed we pass the savings right along to you.

 

hey alvin i might just do that. But the reason i do not want to do head and cam is the $ too much for me right now. I want to do a 100 nx wet shot. I was told that i wouldnt need to upgrande anything really. MAybe a fuel pump. But i was also told that if mine works fine i shouldnt even have to worrie about that. I only want spray for some bigger races. I would say maybe spary it 5 times a month maybe less. Any info would be good.

No I did not use a ALT pulley. Just the 23% crank replacement. The battery volts are low 12's at long stop lights, but I just corrected this by upping the idle RPM's using a Madwolf tune. It wasnt causing any problems, even with my 1200 watt system bumpin, but I just feel better knowing its not dipping down low, who knows, it might kill my opti, and I am trying hard not to let that happen...again. Some use a ALT overdrive pulley to help with voltage levels but your actuall becoming counter productive at that point, why not just up the idle?

The stock fuel pump starts to loose steam around 360 rwhp in my experience. I would replace it if you plan on making more than that.
