3.7 underdrive pulley installed
 
So I finally got around to installing my ASP underdrive for the 3.7. Took a while to figure out how to get it installed without paying the dealership $250.

I have to say,no other mod has improved acceleration as noticable as this,particularly in the lower rpm ranges of idle to 4000 rpm!! I'm not saying it's like a hemi now, lol, but it is noticably better. I'm also running a flyin Ryan ported throttle body, K&N CAI and custom tune. She finally gets off the line smartly,where before it always felt like i was dragging the brakes for the first 40 feet.

No problems with charging or overheating,although the weather hasn't been very warm the last few days to test.

Bang for the buck,this is THE mod for a 3.7

ASP= the brand
a underdrive pulley is smaller,so it takes less energy to turn the accessories,(alt,a/c compressor,steering pump) thus letting it accellerate faster :)
I have one on my hemi & i like it alot also :thumbsup:

ASP Racing - Mopar/Dodge Performance Pulleys

It lists it for 4.7/3.7. Be aware that you'll also need a shorter belt. I bought one about 2.5 inches shorter and that worked perfect.
