Get a JDM flip chip and a JDM ADJ lower pulley with a 4LB and 6LB pulley and then you can have whichever you want whenever you want! If you can only have one I say go with the 6LBer. More power is always better. -Mat-

 

get the 6lber, i'd go cageless, but whatever floats your boat

 

Get a 5# and you would be set.

 

Im pretty sure WHICH VENDOR Im gonna use for the pully ,i might even buy one used but it wont be an interchangeable one.Im looking for differences between generic 4lb and 6 thanks guys ,keep um coming and reasons WHY..........

 

6lb and go cageless, don't waste you time or money on a caged pulley cause they arn't worth it and they really don't help anything that anyone has noticed.

 

6lber and a good Flip Chip is all you need for some GOOD fun.... Plenty safe and plenty of power...

 

I have a JDM 4pounder and flip chip on my truck and i have driven my friends with a JDM 6 pounder and flip chip. You can tell the difference between the two but i like the 4lber for overall long lastig fun. His truck is not a daily driver also. He will pull me a 1/2 car length by the time we get to 100.

 

I went interchangeable...so far though I have only run it with the 6#.

If I could only do one or the other...I probably would go 6#.



Rocks

 

This is a no brainer, if you buy a 4#, you will eventually buy a 6#...so save a little cash and go straight to the 6#

 

Greg,
LOL If that isn't the truth!

 

I have a chip/filter/4lb pulley. I thought about the 6lb but my truck is a daily driver and I just felt like the 6lb crossed the line of safety in my own personal judgement. I would much rather have a 4lb and run high 12's and not have to worry about it, then have a 6lb, run a couple tenths faster but worry about blowing something up. It was a personal thing. I'm sure you can't go wrong with either one.

 

i think the real question hes asking is, will he notice the difference between 6 and 4 on in his normal daily driving routine. You guys telling him to get both or thats hes gonna upgrade it isnt his question. Im not sure but thats the way i read it, in which case, Latemodel racer answered it best, your gonna gain half a truck at 100 and yeah you can tell the difference, i think if you guys elaqborate more on that it would be helpful. I might be way off here but it just seems some of the answers are misdirected, no offence.

 

i habe a 4# no chip for 5k miles
runs like a top and since no one will mess with me now i se no reason to make it faster

 

you still have to get some colder plugs. id go with the number 4
