Ok first a disclaimer. I'm waiting to hear back from Greg as to how he wants to handle these parts. Possibly group buy, possibly Fab Marketplace. I won't be releasing any details about pricing until I get his blessing.
What's all the hooplah about?
Now on to the good stuff. I have two awesome products that should be back from the CNC Machinist shop in about 4 weeks. Over the past 2 months a good friend of mine and I have been talking about manufacturing parts. He's been in the performance scene selling Nissan and Infiniti parts since I met him 5 or 6 years ago. We both have pretty intimate knowledge of the VQ/FM platforms and wanted to make something that similar to the grounding kits in that it was affordable, effective, and could be made using high quality materials.
And this is what was born
AND
Lightweight stock diameter pulleys for the G35 Coupe (03-07), G35 Sedan (03-06 and 07-08), G37 (09-present), G25 (?). This will also fit the 350z and 370Z. FX35 (both engines), M35 (both engines), EX35.
Weight loss is between 4 and 5 lbs depending on the application. Computer engineered and CNC lathed and milled from 6061 T6 Aluminum. These pulleys are very strong and very light.
Rumors
Just to quickly disspell some rumors and myths. Modern crank shafts have been internally balanced for at least 20-25 years. Due to the manufacturing process, these pulleys are also balanced by default. Grenading an engine is not really a worry here.
Performance
On to the performance aspect. Reducing rotating mass is not as clean and simple as saying "X HP increase." Will changing out your cast pulley out for one of these Aluminum ones free up power? Yes. Will your engine rev faster and drop faster? Yes. Lightweight crank pulleys are like lightweight flywheels, they don't truly make any more hp, they just reduct parasitic losses allowing you to get closer to that 300ish HP that the manufacturer advertised (to the wheels).
Instead of going on and on, I'll just answer questions as they come about and add them to this post.
FAQ
Are these pulleys underdriven?
No. But I do have another set that are and can include lightweight accessory pulleys too.
When will these be available?
Target date is June 15th. I'll update this if anything changes.
