I am planning on converting to the Vette front accessories. So I am wondering if I should go ahead & put a GM balancer on it or go with something from the aftermarket....?

 

Really? 48 views & no one has commented.....?

 

I'm just using the stock balancer, I havent seen many failures.... I would go stock unless your wanting to spend the money on an underdrive pulley

 

Might as well get the underdrive pulley. I got mine on ebay for $120, made a noticeable difference.

 

if you have the money for the aftermarket balancer go with that man, they hold up to much higher rpm's, i know the ati fluid dampners work well, and i've heard pretty good things about the professional products one as well

 

I just run a stock one. I've heard of lots of guys on here discover aftermarket UD pulleys causing a high rpm break up/misfiire. This is after replacing everything else trying to track down the cause. Even the SLP underdrive pulley (which i believe is made by powerbond) is advertised that it will not create a false knock. For a few small hp, I'd rather not deal with the potential headache.

 

IMO get a Fluidampr crank pulley, better than stock!

 

I've been running the ASP specialties underdrive pulley for almost ten years without a problem.

 

I would get an SFI rated UD pulley if it were me. I have run a SLP/Powerbond for years with no issues.

 

x2 on the Fluidampr.

 

who has installed a fluiddampr ? i searched and did not see a write up on 1

 

I have a fluidampr p/n 740102, for sale if interested. It had never been installed.

 

The Fluidampr installs just like any other crank pulley for our cars.
I've got the Aluminum 10% UD pulley on my car.



Fluidampr and SLP






Stock

 

have you noticed any difference? any reliability problems?

 

My engine actually seemed to shake less after replacing the SLP pulley with the Fluidampr, none/no issues!.

 

been undecided.........want a stronger specd dampner.......either FD or ASP.....and not a underdrive.......jus may go with the FD
