Re: Asp crank pulley A crank pulley is a great mod! I gained 18rwhp on the dyno with the addition of a ASP crank pulley and ported MAF ends. You can also get the alternator pulley, but if you have an A4 I wouldn't. The lower idle speed of the A4 cars doesn't allow the alternator to spin as fast ( charge ) as with the higher idle M6 cars.

Be sure to check it after you install it. Some have had problems with the pully wobbling (sp?), which can throw off the harmonics off the engine. But I think that was a problem early in production.

Re: Asp crank pulley I agree with Justin. The ASP pulley is an excellent mod for the money. I have had one on my car for almost 2 years now with no issues.
As long as the pulley is installed correctly, you should be just fine.

Re: Asp crank pulley Yep, everything Justin said is dead-on. People have reported up to .1 in the 1/4 from the ASP. I never do just one mod, so I can't say exactly how much it added. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Asp crank pulley Yes, you do need new two new belts. You also need a new crank bolt.
The install is easy IF you have the correct tools. You will need a 3-jaw puller and a 24mm socket. A flywheel lock and a torque angle meter are also recommended.

Re: Asp crank pulley Mike, yes, you do need to replace this bolt anytime the pulley (stock or otherwise) is removed. The bolt is torque-to-yield and once stretched, it cannont be reused.
Here is the process for installing a pulley on an LS1:
-Remove bolt and pulley
-Install new pulley and use the old bolt to seat it by torqueing the bolt to 240lb-ft.
-Remove old bolt and install new bolt.
-Torque this bolt to 37lb-ft and then an additional 120 degrees.

Re: Asp crank pulley Call Thunder Racing. They include the bolt and will tell you exactly what belts you need. I went with a crank under Alternator over with my A4. I needed 2 belts. Order online though, it's 5 % discount.
Re: Asp crank pulley Is it a bad idea to do the crank pulley mod if you are powering an amp for the stereo? Will it slow everything down too much?

Thats what I did when I did mine and when I did the cam. Then just leave it there and it will hold up to torqueing down the bolt as well
