Crank Pulley Replacement

BlackZMamba · 04-21-2016, 10:13 AM

Has anyone replaced their OEM crank pulley with an aftermarket one? If so, which ones did you guys go with and how much of a difference in HP did you achieve?

You have 2 options

STILLEN Pulleys!!!

Don't know if NST is even around anymore.

NST (NonStopTuning) 370Z VQ37HR Pulley Kit Review w/ Dyno Charts

I have the NST setup for years and have not had any issues.

Several threads on this subject already. If site's search isn't working well for you, try any of the big web search engines and add "site:the370z.com" to your search string. Eg, https://duckduckgo.com/?q=crank+pull...%3Athe370z.com

That's the route I went. Rather have reliability than an extra 1whp.

Nope. It relieves a lot of the stresses on the end of the crank and oil pump and smooths everything out.

I dunno know, my 16 4K miles at runs idle runs so smooth I sometimes think it has stopped, have to look at tach

Yeah, but NST scammed a whole bunch of members here and isn't a vendor here anymore.

At idle. It's at high rpm these motors get a little thrashy.
