Hey all,
I am selling my Dinan Underdrive Pulley Kit for M3's built after 5/2008 (both the double sided power steering / AC belt and the alternator / water pump belts are included). Manufacturer claims +11 HP and +7 TQ and I can confirm that the engine reving is definitely freed up when over 4.5k RPM. I noticed ZERO reduction in air conditioning effectiveness and a slight increase in steering feel under 1500 RPM. Aside from that, no negative side effects and a GREAT product!
Pulley Part Number: DINAN D562-0006 D
PS/AC Belt Part Number: 6DPK1050
ALT/WP Belt Part Number: 6PK1435
Retail Price: $399.99 ($499.99 when I purchased it)
The pulley has approximately 1,500 miles with no problems. I am selling because my recent engine mods required the stock pulley. I am the first owner and have all of the original paperwork, receipts, etc.
I am asking $300 picked up in Los Angeles, 90049 (I can meet someone within 25 miles). I am willing to ship and buyer will pay actual shipping costs (or negotiated total cost).
Please PM your questions and/or offers! Thank you!
