I just intalled these, and now engine idles REAL smooth! Great difference even though my stock ones i pulled out has only 7k miles!
Instead of 0.032 i gapped these to 0.044 according to NGK website. The engine is much more responsive and the problem with lag/lack of power at higher RPM seems to be solved!! I highly recommend these when you need plugs!





1st impression is, the built quality is really good! I haven't install this bad boy yet,but I will as soon as I get time this weekend! I will update again on how this thing performs! Most ppl that got this pulley has 5spd, I have a auto so i let you guys know how it performs on our slushbox!

 

Is that the lightweight crank pulley? It looks different than the other pulleys i've seen.

 

They redesigned it after the initial release had measurement issues.

 

i just wanna say that you have an absolutely breath taking pulley...
i mean that thing is good...
i wanna be friends with it...

somebody please know where thats from

 

It's the Perrin piece.

 

Ive heard that aftermarkets pulleys wear out your belts faster...is this true?

 

Could you tell because it says "PERRIN" on one side of the pulley?

I didn't think the Perrin part was an underdrive pulley, but rather just light weight. Don't know why I thought that...

 

Regarding the iridium plugs, I tried them last week. Since my system has a voltage stabilizer hooked up to the battery, I notice very small power improvement from the plugs. The warm up time is a little less and the car has a little quicker response at high speed, although the power increase for the whole band. I think this upgrade is not necceary if your car has a clean electrical system (that has ground wires and voltage stabilizer).

 

I'm gonna throw something out there. If you like it, keep it. If not, just send it on back:

I wanna be on your pulley.

...I wanna be on your pulley!

 

hmmmm cant wait to hear how the install goes, where did u get the pulley from, i was going to get it from vividracing i guess im a parcial sponsor for them or suttin, they dont get back to me though so i dont know............

how did you gap them? i hope you didnt touch the center electrode. if you did they arent iridium anymore.

im due for plugs soon. (500Mls) how much do they run?

 

Got it from vividracing. I wouldn't recommend them at all! In fact i've see cheaper prices on ebay! It was a real hassle dealing with them! I actually ordered these over a month ago! and after a bunch of E-mailing/phone calls + paypal disputes, FINALLY got into my hands!

 

I gapped them with a cheap gapping tools from autozone, Just have to be really careful not to rub on the center electrode. Also it costs me $36 shipped from E-bay so i guess that would be $9/ plug including shipping!

 

The pulley looks amazing. Have you installed it yet? Any feedback?

 

Yes, installed!!! Anyway... install was a breeze! much simple than the others that I have done!(Eclipse, Civic etc...) Revs slightly faster from 1k to 4k rpm and much better throttle response! I have an auto btw... However, its not as good as I though it would be.... since it does not underdrive! Still worth it overall though!

 

good to know that it does help a little and the install is easy

 

let me know how the pulley works ! looks great!
has anyone used hopupracing .com?
perrin pulleys 129.95

 

just wondering if $130 for almost no gain and something no body really sees is really worth it?

 

take it to the track and see...

and its no gain (not--almost no gain)
these are not under drive, they can not produce power...
they free up some power by reducing rotational mass...

yes its worth it...
