Accessory drive recommendations?

[roguegeek]

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.

Makes sense. Now I just need to decide between Drive Junky and Wegner. 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.
