I just bought two pulleys. A 4# and a 6# I have heard that there really isn't a big differance in gain with the 6 over the 4 Has also If I get the chip burned for a 6# and run the 4# will I be ok?

 

If you install the 6# you will put the 4# up for sale shortly. Many guts on L forums have started with a 2 then went to 4 and then 6. So I just went directly to 6 and am extremely impressed with the results.
You know power is addictive- once you start there is no where to stop- everything is more, bigger, faster!!! so I recommend the 6# and good chip. You also should install the boost pypass if you do not have it yet. $4 asnd 5 minutes makes a big difference.
just my .02

 

Thanks man! yeah I have the bypass kit already. I guess Ill go with the 6#

 

I can't imagine why one would further overdrive the already overdriven supercharger for only 3 more HP?!!! 15 HP for the 4 lb. vs. 18 HP for the 6 lb. 3 HP!
Leave the spare at home and your power-to-weight ratio improves more and does not threaten to blow the motor.

Just look at the chart below. Now imagine that it extends to 16,000 RPMs. It's your funeral.

 

Tim,great charts.I wish I would have had those charts for explain some past conversations I've had.I hope you don't mind but I just ripped both charts to save.Thanks for posting.

 

Actually torque is what you gain most with the 6.. The second Eaton graph has been around for 4 years that I know of...When Gen 2 Lightning's first came out in 99 EVERYONE said it's not worth it to go bigger on the lower pulley....well guess what? It is..Take a look at allot of your quickest Lightning's and they are running 4 to 6 lbers.. How many Eaton's have you heard of that have blown up? Freedom of choice makes this country great..

 

Since you have 3 post I feel I should warn you about Detenation. Cool weather will break a plug or a rod!! Enjoy!

 

Yes detonation is bad That is why it is essential that you have a good working relationship with your tuner and run good fuel. There are a few high 11 low 12 second Lightning's out there with stock internals and no N2o and M90 Eaton's as daily drivers.

 

Ive ben a member to nloc for some time now, I just joind here thats why my posts are low. I hae a chip and run 94 octane. I just hard that people were hving better luck with the 4# over th3 6#? Thnks for theCharts! and thanks for your guys help!

 

Hmmm... I think it's time for a new keyboard...leaving out some leters

 

I have ran all size pulleys and will tell you that the larger pulleys work. All the pulleys I have used, the 5# - 6# pulley would be the one you should use. Make sure you get your chip program right. The torque and the instant boost off the line is what is giving better times. I now have a 8# pulley and it seems to work. Will be pulling some times down on Sunday @ E-Town.
