4lb or 6lb pulley for stock Eaton?

[Poon Pounder]

I'm comtemplating whether or not to get a 4lb pulley or just go straight into the 6lb. I heard its safer to go with a 4lb, but what other modifications would i need for a 6lb? Right now i have a AEM cold air intake, LFP single blade throttle body, and flowmaster exhaust. I have heard that the 6lb pulley causes the eaton to get overheated; if this is the case what do you guys Recommend?

Thanks for the help,

Mason

Welcome to the site.......

I don't think a 6# will overheat the Eaton. It will make a little more heat than the 4# will, but I don't think it'll be an issue. What year is your L? It wouldn't be a bad idea to upgrade to a 90mm MAF or get a MAF extender. Other than that, just re-gap your plugs to .034". A DYNO TUNE IS MANDATORY!!!

I have a 2001. I was thinking about just getting LFP Stage 1 SCT X3 Power Package with the 6lb. That Sct handheld tuner would that be maybe equivalent to a dyno tune, becuase I live in Twin Falls, Idaho and the closest Dyno is two hours away.

I'd go 6 with the proper supporting MODS and ditch the canned tune from LFP.Do yourself a favour and get a good dyno tune from a reputable tuner, a 2 hour drive is much easier than putting a hole in your block.

4lb is safer w/o internals but if u go with a 6lb its border line. but both u will have to change plugs and get a trust worthy tune.

 

[MJG]

4lb can be just as dangerous as a 6. People seem to forget that running anything that isn't stock can lead to problems if not properly supported/tuned. Many 4lb trucks blow too. Again, thats why I'd recommend a GOOD dyno tune.
Just because you get a 4 instead of a 6 does not mean your 'safe'

im with MJG.....also if you get a 4lbr i can almost guarantee that you are going to want a sixer down the road soon after you get it on...

good point but its exactly what i said except more in depth. i was saying u can get way without internals with a 4lb. im sure most people knows if u change the air flow u definitly have to get a tune. or you will be running to lean. but your right and i am to just i didnt get much details.

Just go with the 6. That's what I did and the truck is still too slow. Now I got a KB sitting in the garage. Dyno tune + supporting mods, your good to go.

 

[tribalightning]

lol my 6lbr isnt even on yet and im thinking about a KB or Whipple

 

[MJG]

I did have a 4lb'r, then ported my blower and got a 6 lb. MUCH better. but good tune and supporting mods it's sweet.

 

[Poon Pounder]

Okay I know what i shall do. Thanks for all the input guys

why arent u in the 400's?

 

[kidlightning5]

Get the 6# with supporting mods and tune because if you go with the 4# you'll want to go to the 6#.

go get em poon pounder

 

[tribalightning]

^^^^ lol that sounds awesome

That's a very good question. Don't mind those, they are just #'s. I think the dyno I went to measures low.

I have yet to run at the track. Hopefully it can be done this year, if it is even open
