well i finally got around to putting the NST 9.5lb pulley on my s/c. alot of u auto s/c guys know that i said i was gonna get around to this like months ago lol. but things come up and plans get pushed back. well it's finally on and i'm loving it! theres a harder and longer pull in the high end now. before there was a nice pull in the low to mid range, but towards the high end, you couldnt feel it as much anymore. now i can feel the pull even in the higher ends! i'm going to tune in a bit..gotta get money together to get the pnp harness.

oh btw, right now i have the forge 007 bpv on with the weakest spring. just wanted to know which spring to switch to to hold better boost, so if anybody can ping in, please lemme know thanks!

i dont know of anybody that hasnt been satisfied by NST so if you're in the market for a pulley, definitely hit up mike on aim, the sn is NSTonAIM. or check out their website www.nonstoptuning.com.

 

I asked about what spring, answer I got was red spring...

 

thanks!

 

You should re-dyno now to see what kinda numbers your putting down now. Im sure it was atleast a 15whp bump. Manuals usually gain around 15-20whp with a pulley swap I believe.

 

i'll do that when i tune since i get a baseline dyno before he tunes anyways

 

supercharger holding up good?

 

yep, new blower's been perfect. doesnt even make that ugly rattling noise. i just got the pulley put on so we'll see how it goes

 

The springs are rated as follows:
Green 5-15
Yellow 15-23
Blue 23-30
Red 30+

This a general guideline that was honestly developed for turbo applications. Not too sure if the vac/boost relationship on a supercharged car will change the spring requirements... Of couse the problem with too stiff of a spring would be that it might not open at lower boost levels.
