so its a harmonic balancer?
1972 240z w/L28, tokico shocks and springs, and a 5 speed waiting. Also running high performance ultra mega blinker fluid, that's at least an extra 50hp to the wheels.

A:


Ok lets please let us clear this up once and for all. The technical name for that part is "harmonic damper" now the damper is balanced, but it is not correct terminolegy to name the part harmonic balancer, it is a balanced damper.
According to the information, you are correct, this part is a damper.
I wish I could have found this part say 3 years ago. I was looking to go serpentine belt to the alternator.

very nice find, too bad I dont have $525 nor a need for that kind of a damper!

Hey Jeff Im in a market for a perfomance Dampner for my stroker, have a n extra spare? I will most likely call Dave Rebello next week if I cant find any other sources. Later!

ive got an all aluminum one made my LMI technoligies---
it was a billet 3 belt one, but when i went to pick it up, they put in on the lathe and let me hack off the two other groves---first time ive ever used one before.
the thing weighs about 1 pound...no kidding. it looks SWEET too

Looks like you add another 137 for the water pump pulley... I don't see the alt pulley listed anywhere but now it up to 662.
Why do the Datsun guy always get burned on the price... LOL
March make a complete kit for the SBC with all billet parts that include automatic tensioners, a high out put alt, water pump, A/C and even power steering. The complete kit minus the power steering is about 2000 bucks...

LOl Bubble to bad you have that piece on a slow car ;) LOL
Nice piece though Jeff! would be great for supercharger set up

Frank I was just thinking about it for my supercharger engine project. I think it would be perfect. The alt pulley is probably just generic. I was thinking of how to get the rib belt for the supercharger to attach to the V-belt of the engine. I was pondering having a rib pully welded to the balancer to drive the supercharger, but I thought it would be hard to get exactly correct and would be expensive to do. I will see if it less than the balancer/water pump set there.

I did not realize I posted that many times. True, I don't know how to post a picture to show in the forum, but then again a click away is not bad either.

I understand the damper and why a better one is needed. My question is besides adding a supercharger, when and why does one need to go to a serpentine belt design?
Matt

A:


The serpentine belt configuration is far superior to the vbelt configuration in my opinion.
signed pseudotechnician view point, Sniper S^$ker, with girly arms : UCC 1-207

A:


Yes, but when is it necessary when your not driving any accesories other than an alt & water pump?
I mean my vbelt setup, stock pulleys except the damper, sees 8K all the time and has never had any problems. Does the serpentine provide less friction or is it just a stronger belt.
I'm not arguing your opinion, which I share, I'm just trying to figure out why I would want to spend $500+ for parts that may not make any difference at all other than looking nice. I can see it on your setup, with the power your making I'm sure it's easy to slip a belt but for those of us under 350 hp it hasn't seemed to be a problem.
btw, how's your car, haven't read much about it lately?

Haha that is what i was thinking for my SC project.. where will you mount yours !?

Well since I have taken the time to have a damper developed, that will retrofit directly to the Nissan setup, I am running the v belt configuration as well. I have had some problems with the alternator getting lose. I think that is solved.
The BHJ unit is cheaper, and it is SFI approved for racing, also a trigger wheel is easily installed on the part.
I don't know where the email came from, but I thought I would share the info.
I like the setup myeslf, less belt flop and belt vibrations. The super charger is perfect for this setup. This is more expensive to retrofit on the cars then the BHJ unit.
Still looks to be good quality and worth consideration.

I can imagine the torque put through your belt system when that turbo hits! You may need a gear drive setup!
I like the BHJ unit you commissioned, that's what I run, so thanks.
Speaking of superchargers, we mounted a vortec using a 240 AC compressor mount without too much modification. We didn't have pulley options so we made those as well for a 6 rib serpentine.

What method is used for the dampening? BHJ, is a coil spring style, stock is rubber, some are fluid, which is this, it does not mention.

I had asked about dampeners a while back. You weren't sure of it being suitable for our applications. Your concern was that it had an elastomer ring that could possibly fail. Jerry finally was able to mass produce the dampener beyond the VQ engine and is now selling them for the L series engine. A little checking around and you will find a slideshow blow up of the dampener.
The only part he lists as available that I cannot find is the alt pulley. It's listed as available, but not yet posted as such.

You may not want to get a lighter harmonic balancer for your SC. The less weight on the dampner/harmonic balancer, the more sensitive it will be.

Well Matt, the car is doing alright, I did get it to the MSA show this year and it was running well enough, actually the fastest it has ever been, and making the most power it ever has. I am now forced to get some drag radials, or wrinkle wall slicks to really run now. The breaks traction in 2 and third no problem just with accelleration.
I have been playing with this new tuning program I have and it is working out good. I have a stumble @ 2100 rpm's that just wont go away. Total pain in the butt in traffic, well not unmanageable, but you know what I am talking about.
I think it may be hardware related and the way the MAF is installed on the car, but I cant be sure. I started taking MAF readings coming home from work yesterday, but could not find any problems with the scaling, its like a sensor is telling the ECU I want NO fuel now, just for that short blip of the rpm, irritating.
Then the other problem is when it is just starting. The car runs good, good AFR's then it starts leaning out, and leaning out to the point it will stall, then like a switch it clears, richens up to stock and is fine, total irritation.
So I think I am dealing with two problems in the low RPM range, you know where you drive on the street LOL but other then that, if I run race fuel I have already boosted the car to 25psi and it was very strong, I need better tires, or run it on the dyno. I am quite sure I have hit my 600hp mark @ the flywheel.
Now it is just a matter of dialing in the low rpm range for drivability on the street, so irritating, 2100rpm flat spot. I am going to run some tests with the cylinder head temp sensor today and see if I can simulate the problem with a resistor decade box.
I will get it sorted sooner or later, probably later after I have pulled my hair out again LOL, sometimes this car really is a pain in it LOL, well maybe most times LOL. But hey, it's the Z

That would make bolting on the supercharger to the L20B in the 510 much easier....

I was thikning on a bolt on bolt-on pulley that drove a Gates HTD pulley anyway. I think the Gates Cog Belts transmit the power better, the serpentine will have to wrap 3/4 of the way around the charger pulley to transmit the torque to drive it at higher rpms.....
Not that I have given it much thought...muahahaha!

Thanks Jeff,
Sounds like your car is about ready, sounds awesome. Those somewhat intermittent problems can drive you crazy but you'll get it, sounds like your well on your way.
I'd love to ride in that thing, and can't imagine it on normal street tires, lol.
