@  Fast86GN : (04 March 2019 - 07:05 PM)

I don't think it would that loud probably depends on the mufflers used?

Hello everyone! Its been a long time!. Looking to get back into the game. Anyone have a GS on the east coast they wish to part with?

@  ejguillot : (14 February 2019 - 09:08 PM)

Still have a Regal GS project that has taken way too long to build, and it's nowhere near done.

I've got to pull the original harmonic balancer on a '98 Buick Regal GS with about 150k miles in order to install a new crankshaft position sensor.

 

I'm wondering if it would make sense to buy/install a new harmonic balancer while I'm at it. I've already installed all new accessories recently, along with tensioner and idler pulleys. Heck, I even replaced the A/C compressor with a delete kit just recently after it siezed and snapped the belt. So only the harmonic balancer is still old/original.

 

I looked on Rock Auto and was surprised to find out there are a few options. Normally for this I would go ahead and purchase a new ACDelco unit, but it looks like Dayco makes a couple different versions. It's hard to tell by the description if they under drive the accessories or overdrive the supercharger though.

 

I really don't want to under drive the accessories or overdrive the supercharger. I already have the ZZP modular pulley on the S/C snout and I would rather change that way.

 

Has anybody else seen or bought these Dayco harmonic balancers? One of them looks like it is made from billet aluminum. If it were a lot lighter than I would be interested...maybe.

I wouldn't change it if it's not making any noise.  If it starts acting up, it is easy change later as long as you have the correct puller.  I think the Lisle 45300 is the one you want.  Other universal puller sets can damage the crank sensor and/or balancer. Balancers on these engines do not have a bad reputation for going bad, not to say that it could never happen.

Thanks, and it's not making any noise or anything. Also thanks for the proper tool part #! I did see that Intense sells a similar one (Dayco Powerbond), that is stock diameter or 5% overdrive on the supercharger. The one from Rock Auto you can get with 10% under drive for the accessories and stock supercharger diameter, and it's quiet a lot cheaper. I guess it's tempting considering I have to remove the old stock one. The Intense listing says it's a lot lighter than any steel balancer, and it has the option to run an 8-rib belt for the S/C. I believe my ZZP mod pulley also has that option.

I'm running the 8 rib. As you mod and tune for a smaller SC pulley, the 8 rib will help to keep the belt from slipping.

I can only see myself going smaller in S/C pulley size with further mods. The 3.4" mod pulley has worked great so far for the past 7-8 years.

 

What harmonic balancer do you run to allow the 8-rib belt?

Not sure...bought it used on one of the forums.  I do not think it is over or under drive. I never compared it to the original.

Mines 8rib. Looks like a a stock unit with 2 extra groves milled in.

I wouldn’t bother replacing if it works and doesn’t look like it’s cracked or damaged.
