Hi

Let me say Thank you for all the amazing helpful threads. I have a 06 RL Tech (95k) and am doing a complete timing belt service this week and have read on here about installing a aftermarket Crank Pulley. Can someone please help me, Im not sure which one to get. Ralco is fine Im just not sure if I should get the Underdrive Crank Pulley or the regular Crank Pulley, I am assuming the Underdrive is the lower and the other is the top pulley? Which one will give me added performance?

Also any suggestions of additional maintenance I could do at the same time as the timing belt kit.

I am using these parts:


Timing Belt Honda -14400-RCA-A01


Idler Roller / Pulley Koyo OE -14550-RCA-A01


Tensioner Roller / Pulley Koyo OE - 14510-RCA-A01


Water Pump & Gasket Honda -19200-RDV-J01


Hydraulic Tensioner AISIN OE - 14520-RCA-A01


Front Camshaft Seals x 2 Honda - 91213-R70-A02
Front Crankshaft Seal Honda - 91212-R70-A02


Serpentine Drive Belt Honda - 38920-RCA-A03


Thermostat Tama - 19300-PR7-A02 with gasket

Silicone Sealant Hondabond - 08718-0004

No.

Under drive means it will under drive the crank by using a smaller sized pulley. It still is a crank pulley. (Lower)

The stock diameter aftermarket pulley will give the same benefits because it's lighter. 1lb vs the stock OEM 10lb pulley.

Every one purchases the stock sized aftermarket pulley because they don't want to run into problems under driving the engine

Thank you for explaining it. Anyone that has purchased one please send me your feedback.

Plenty of people have purchased and documented it. Find the "search this forum" toolbar in the forum to do a search.

Like justn said, you want the stock size. The RL electronics are already hard on the charging system. You don't want to cut into that any more.

in theory, lighter rotating mass will make your car quicker, thats the whole reason why people use lighter pulleys
