Hey guys just wondering which pulley to use, a 4 or 6 lb lower?
My trcuj is mainly street driven, so sort of looking to see which one is better on the street. Ho wmuch did you pick up going from a 4 to a 6#?
Also, if I run the 6 lb. lower, would I need a larger heat exchanger and thermostat?
Also what other mods, would help get the power of the 4 or 6# to the ground?
Thanks,
Simon

 

Just stick with a 4lber, make your life easier, from what I have read a 6lber just produces more heat than its worth, some will disagree but thats just my opinion theres a reason why some call our blower a Heaton...

 

assuming you take the time to dyno and get a safe tune...

the only disadvantage that I can see to a #6 lower would be the extra tire wear!



I run a 6lower on my daily driver. i've got a built motor now, but I ran the 6 lower for 13,000 miles without the new motor.

I ran a 6lower and 1.5upper on my '01 truck with no problems.

good luck.

later,

I could not decide between a 4 or 6lb pulley so I got a 5lber.

 

I have a 4lb but with a ported s/c. IF you plain on porting the sc go with the 4lb if not then its your call but id go with the 4lb since it helps on heat on a street driven truck.

 

go with a 4 man, you dont gain enough with a 6, and any gain is downgraded because of the extra heat

 

lol, I like how you think

 

i've got a #6 on my daily driver with no problems so far...I ahd the 4# and eventually wanted something new, so the choice was obvious...I just wish I would have done the #6 in the beginning and saved myself some moeny...
