Pulley Q's

[airstuff]

How many of you guys run Aluminium lightweight pulleys like Scat,Cb Performance,Saco or other street pulleys.

I see some of the quality engines here on the forum like Jason Fosters engine and others running light pulleys.

How long do these engines front bearings last in addition to the same engines fitted with Berg equalizer or Achiever?

[Jim Ratto]

I run a steel pulley not because of weight, but only because I don't worry about the ID of the pulley wallowing out on the crank, which usually results in the OD of the pulley tearing up the nose of the case. I've run aluminum pulleys in the past and had one or two do that. I just run the normal weight Berg pulley. (well in the winter I'll run a Santana power).

How many cars sold today run aluminum pulleys on a steel crank? Something to think about...

[John Rayburn]

My balancer told me years ago that the Berg heavy pulley was the greatest thing he'd seen. I've run them for years and years and can't recall ever needing a line bore since.

Yeah, but John you never drive over 3500rpm!

[John Rayburn]

True.

[Jim Ratto]

True.

is your car a diesel?

[John Rayburn]

No, it's an aeroplane.

I've had an aluminium pulley split down the keyway, no major damage done to the engine - just bolt on a new pulley and go. Noticed a squeak at idle, then a quick flash of mag fire from the case. This was just at fire-up in the pits. But then I've also had a Berg Equalizer come off and destroy both crank and case. Followed all the Berg instructions to the letter but sh1t happens. I think I'd use another aluminium pulley, but the solid one, not the one with the holes, as the split was between the keyway and one of the five holes in the pulley face.

and what's up with those Jay Cee street pulleys which have the steel hub?

[Mike Lawless]

The new batch of steel hubbed pulleys are pretty nice. Right now I'm running a Bugpack hub and my own custom pulley, (to clear the autocraft pump). CB's new line of pulleys have steel hubs and are really nice pieces. At the time I put this together, there wasn't a dry sump size pulley with a belt groove available. Now there is.

The Bugpack hub I have is a nice tight fit, requires a puller to get it off.

Years ago, I had a Berg 6" equalizer. It tried to weld itself to the crank. So did the flywheel at the time. (not wedgmated). The flywheel problem most likely was the cause of the pulley problem, but the engine was seeing over 8000 rpm at the time. The Berg pulley is a really nice thing for a street engine. For a drag set-up, perhaps the shock of the clutch engagement led to the "welding" problem too?

I ran a dry sump pulley with a groove on Friday nights on my street car in the early-mid nineties.

I ran a dry sump pulley up until last Sat!

[Mike Lawless]

To clarify, I meant to say a new style  dry sump sized pulley with a steel hub was unavailable, (except for the Autocraft unobtainium pulley). I ran a CB dry sump size pulley before the current one. I should have been more clear.

Something else to know,the ally pulleys are offered in billet or cast,this may be the issue?

cheers richie
