According to this link Eurocharged has a pulley coming out that produces 12whp.
After speaking to an EC rep the other day it should be available in the next few weeks.

This will be my next modification but wanted to see if any others would be interested as a GB for better pricing.

I'd be in, but im so cautious when it comes to pulleys. The ones evozsport made usually ended up failing and much more hassle than they were worth.

Autosport7

Well this is interesting! Care to elaborate...? I haven't heard of any issues, I sure hope EC doesn't fail at this. I have been counting on this pwr increase since I heard about the release.

Price?

We need a ROW air boxes group buy too . . .

mthis

U want row boxes I'll sell them for cheap but they have no mafs.
They new never installed. I bought them bc I needed new mafs so I took the mafs and now they sitting in a box new.
pm Me a offer if you want them.

I heard a few instances of issues with Evo sports pully.
But then again this is a EC one so it might be stronger.

Is it really worth 12rw for what it will cost and what it will cost to install and the headache of someone installing wrong.

PM sent!

I justified it by saying "people are paying $3k for an exhaust" so this isn't bad. Then I realize I only paid $250 for my UR pulley for my Z! Lol

Orrrr $1800 for a CF Intake that nets zero gains.

At the end of the day if you want to make power in this car you have to pay up. IMHO none of it is worth what we're paying, but we do it anyway.

Im in, since this does not require any re-tune its perfect for those who are looking to squeeze 12 extra horses out of the car.

Gents for a Naturally aspirated motor 12 WHP is a lot. Now is this pulley worth $1000+ dollars? nope. But it does have higher yields compared to some of the other available engine mods for our cars.

ROW's on their way folks! Thanks for the deal mthis!
ROW's, pulley an V5 tune my buddy in his CTSV will be in the rear view! Until he gets a pulley!!!

I'm in for a pulley ..you should be pulling you're friends CTS-V stock I've raced a few and beat them every time, they never seem to be able to hook up from a dead stop ..but the supercharger sounds sick i'll admit and pretty fast once they get going

shades

I'm in if the price is right

I'm interested as well for a group buy!

I read on other cars underdrive pulleys can damage components connected to the drive belt long term like power steering or alternator. Does anyone know if there are negative repercussions using this long term?

Mort

There is no free lunch. You should be aware of the fact the underdrive pulley will spin all belt driven motor accessories at a slower speed than anticipated by the manufacturer. The one I see discussed most is the alternator, especially if aftermarket amps are used with subwoofers and see larger pulleys being used on them. This sort of defeats the purpose of freeing up HP by reducing the drive pulley diameter and mass. I have never bothered with underdrive pulleys myself but there is info out there if you search. Also undampened pulleys have been known to cause some issues and dampened ones known to fall apart. You can also get lighter pulleys to gain some lessening of rotational mass but no change in size for this reason. Less gains but less compromise with other belt driven accessories. Worth doing some research before committing to this mod. This seems to me to be more of a hardcore racing mod than a street friendly way to free up a few more HP.

ruey220

understood and thanks for the tip. I just figured a blower will also reduce life of engine but you're talking about adding close to 100+hp to risk engine life but have more enjoyment in the short term. Adding 12hp, pay $1000 and lose an alternator and pay another close to $500 or so to repair every so often, definitely is more of a racing mod, vs street friendly. I think other things like ROW, ECU, or even exhaust can give good hp gain without any long term effects, give me more piece of mind. I thought perhaps there was a way to negate the downside of having this such as placing a different sized pulley on those other components attached, but then again it probably also negates the hp gains on the pulley itself.

ROW's arrived! They look beautiful! Thanks mthis!

No aftermarket parts and accessories boosting power is probably "GOOD" for the longevity of the vehicle. I may put 2000 miles on my car a year, I personally will probably never see the long term related issues heard of.
