Accessory drive recommendations?

[roguegeek]

73 Camaro with a Speedtech ExtReme subframe. I'm probably going to go with the LS427/570. What accessory drive systems are you guys running? I'm thinking about one of those Holly mid-mount systems (https://www.holley.com/products/ls_power/ls_and_lt_accessory_drives/gm_ls_accessory_drives/mid_mount/complete_accessory_kits/parts/20-185BK), but would like to hear about what everyone else is doing.

[roguegeek]

Some of the other ones I've being given as options are Drive Junky (http://drivejunky.com/product/high-ac-ls-drive-system/), Wegner (https://www.wegnerautomotive.com/drive-kits/lsx-drive-kits/coil-pack-ignition/wak033/), and Concept One (https://www.c1pulleys.com/collections/chevy-ls-victory-pulley-systems).

I prefer holley accessory drives, they use many over the counter parts so that makes repairs easy ....

What do you think of that whole plate system they use instead of normal brackets? Looks like a cool solution, but does it add a lot of weight and does it take up real estate?

I have the mid mount on my car. Great unit with tight packaging. I don’t think the weight is much different that the others. I think the alternator is great (big amps at idle when you need it) and the water pump is easier to change (C7 style cartridge). Assuming you are going with the Extreme and are going to track the car. I am considering changing the PS pump from the stock Holley type 2 to a Turn one unit. I am getting a seep from the pump shaft after about 2 years. Other than that it is an awesome setup!

Does the new 570 horse wet sump version of the LS7 still use the stock LS7 crank with the long snout? If so, you'll need the crank spacer from Scoggin Dickey to take up the extra length. No big deal. I have the Holley mid mount for my LS7 that is converted to a wet sump using LS3 components. It's not in the car yet, but have heard good things about it.

Yeah, the car is going to be on a track. The PS pump on the Holly, you're finding it's not adequate?

I'm not sure, but I'm glad you mentioned it. I'll keep an eye out.

I am not saying it is inadequate but I think most guys upgrade their pumps for track duty. The Turn one stuff is great! I think my shaft seal is going bad from too much sitting.

The Holley Mid-mount is an excellent choice.

Well the reason I ask is because Speedtech and Sweet do recommend a very high-end pump for steering. So I guess I'm just wondering if the stock Holly fairs well.

[130fe]

I would say in street application the Holley unit is great, if it is in a situation like yours then I would look at the Turn one unit (no matter what drive system you go with). I am getting ready to upgrade my suspension so I am looking at the Turn one unit also.

Personally I doubt the Holley mid mount has enough power steering pulley belt wrap for a car that will be tracked. Not even close, the belt just kisses the pulley.

Wegner has excellent wrap....

not sure what holley "stock" is but the holley kit uses a 97 or newer corvette steering pump and inside that there are levels of pumps, I use the lightweight aluminum, 2.8 GPM High Flow, 1350 PSI unit that coupled with a steering cooler and power steering filter, one pump replacement in 8 years.. and I turn a lot or rubber

I think I'll be upgrading the PS pump on any of these systems to a Turn One pump, so I'm not too concerned about what comes with any of the assembly drives.

[roguegeek]

Still haven’t made a decision on this. A lot of the Speedtech guys are running the Drive Junky accessory drive and then upgrading the PS pump to the Turn One. I’m having a hard time seeing why it’s so much more than others. I’m hearing the components are nicer, but what do you guys think?

I have about 700 miles on Drive Junky drive, 68 Camaro LS1. No problem at all. The belt wrap on power steering is the key reason I went with it. Speak with them, I believe pump is a Jones Racing unit.

Don mentioned above the belt wrap on the steering pump as well. Can you elaborate on what you guys are seeing here in terms of advantage and disadvantage? To my untrained eye, I can't tell the difference.

Edit: Ahh, I see what you guys are talking about now. You're talking about the length of belt on the circumference of the steering pump pulley. I'm guessing with stronger pumps, there's a danger of the belt not being able to turn the pulley if it isn't engaged enough?

[dhutton]

With insufficient wrap on the pulley you can get belt slipping and squealing under load. If it slips you lose your power steering assist which is not good. Track driven cars need maximum belt wrap.

Systems where the belt just kisses the pulley are not suitable for track driven cars imho. Even the OEMs strive for good belt wrap.

I’m running a Wegner front drive. Amazing customer service and product.

Makes sense. Now I just need to decide between Drive Junky (http://drivejunky.com/product/high-ac-ls-drive-system/) and Wegner (https://www.wegnerautomotive.com/drive-kits/lsx-drive-kits/coil-pack-ignition/wak033/). Between those two, which do you guys feel has the better PS pump? If I can put off buying the Turn One pump for a little bit, that would be helpful. The following are Speedtech's requirements for steering pump:


ExtReme Power Steering System Requirements

The Sweet dual power steering rack is a very high quality part. Considering the way Speedtech has spec’d its internals for maximum all round performance and through extensive testing and racing our Sweet equipped test cars we have come up with the following critical requirements to ensure proper function, reliability, and longevity of your power steering system.

The use of a very high quality power steering pump is required
• We recommend either Jones Racing or Sweet Manufacturing.
Both of these pumps are hand built and have extensive internal modifications to increase both performance and longevity over any other pump that we are aware of.
• Do not use a factory style or spec'ed steering pump.

MAXIMIM RPM of the steering pump is 5200 RPM
Please ensure your pullies are sized for this max speed accordingly with max engine RPM. Although individual needs may vary, we generally recommend:
• 5” crank Pulley
• 6.5” power steering pulley

Required Power Steering Pump Specifications
• 3+ Gallons per minute
• 1300 psi

We recommend a series 60 eccentric in the power steering pump.

You MUST use a quality power steering cooler
• Minimum of at least 44 sq inches.

You MUST use a high quality fluid, we recommend
• Jones full synthetic, or
• Sweet full synthetic

Also, which is more easily serviceable with common parts in case something fails in the field?

Edit: I'm heavily leaning towards the DJ kit. All of the Speedtech cars are using them and it looks like it's everything I need and more.

Purchased the Wegner WAK033 (https://www.wegnerautomotive.com/drive-kits/lsx-drive-kits/coil-pack-ignition/wak033/) yesterday. Solid black everything with the 225 amp alt. The PSC power steering pump is spec'ed at 3.1 gal/min and 1500 psi compared to 1100 psi of the Jones unit on the Drive Junky. I'm sure both are fine, but not a lot of the Speedtech cars were using the Wegner and I like the idea of trying something different to see how it works.

Thanks everyone for your help.

How did this accessory drive work for you?

Wegner Automotive no all the way.
Excellent quality, fit and finish

I might mention mine is a Speedtech equipment car. Not the xtreme but the original pro touring sub up front and torque arm rear.

Has anyone used an accessory drive from CVF? Considering the LS mid mount for a late second gen firebird.
