BUT given the real Under pulley done by people who know what they are doing then you can really increase ur BHPPLUS you need to change the whole cooling system to be electrical and that will reduce the need for the engine to turn those fans...Im no expert but this is a fact i guess...but look at these...<img src="http://www.turnermotorsport.com/image/engine/engine_udpullies_lg.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Kit includes water pump, power steering, alternator pulleys and belt. The T-6061 hard anodized aluminum pulleys account for a 10 to 20-percent decrease in accessory speeds, reducing the load on the engine but still maintaining a safe margin for reliability on all components. Installation involves removing the fan for easy access to the front of the engine. The main drive belt comes off easy and each pulley is mounted with Allen head bolts. Typical installation time is 1.5 hours. New main drive belt is included. The pulleys were good for 10.7hp at 6960 rpm and 8.1 lb-ft of torque at 5550 on the 1995 M3. <img src="http://www.turnermotorsport.com/image/engine/engine_pulley_dyno.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
