I have the ASP under drive pulley and felt it was a GREAT mod. I did notice a difference both times I installed it. I had to remove it to have it modified by ASP and it felt like a slug with the old pulley back on... as soon as I received my modified pulley I noticed the power was back. It rev's noticeably quicker and I gained approximately 2+MPG when I installed it. I have NO charging issues what so ever with over 40,000 miles on my pulley.

I have another ASP under drive pulley that I would sell to you for $190.00 BUT the only catch is it needs to be sent back to them for a modification due to a recall. All they did was increase the ID of the HUB so it clears the cam sprocket ledge on the crank shaft snout. No big deal ... they had mine back to me in less than a week. All you will need to do is contact Lee at ASP and tell him you have purchased a USED unmodified pulley for the 4.7L, he will modify it for free... I just have not had the time to send it in to him.

Let me know... If I send it in and have it modified I will charge $200.00 ... and it will go in a heart beat.

it sounds like a worth while mod. who is ASP? do they have a web site? thanks

 

anyone else have one on their 4.7 ram truck?

 

air ram in your bio it looks like you have cams in where did you you get it from and how do you like it comparied to stock

 

I got my cams from FAST MAN....

I have the 212 cams and because there is NO programer or program for these cams I recomend the 206 cams instead... the 212 cams need a torque converter to get the RPMs up to where these cams make POWER. Call Dan and talk to him about what he has to offer you and your 4.7L... Tell him AIR RAM sent you, he will take care of you.

I wonder if an underdrive pulley is a good idea for my hemi...

 

Do you race your truck? Cause that's the only reason to get one.

 

Street-race... I know it's such an immature thing to do... But I also have the need for speed, I like to accelerate quickly. :P

 

Go for it Rob! Every little thing helps...you won't notice any performance...but it's gotta be doing something.
