Help me choose pulley combo

[joes03cobra10thann]

Over the last week I have been doing some research on different pulley combo's so far I am leaning towards a 4lb lower and a 3.1 upper or a 4lb lower and a 2.93 upper what one would you recommend?

My only mods are magniflow o/r xpipe and magniflow catback.

Here is one of the sites that I got the information from:

I'd wait until you get a port before you get that aggressive. I run just an 8 lbs lower and have never had any problems.

One of these days when it's nice out we'll have to get together.

If you are set on doing a lower go with the 8lb. Keep the stock upper or a 3.4 with the stock Eaton. Switch to a 3.1 upper when you get a port

With either of these combo's I am thinking about going with will I have to get a new alternator pulley or any other pullies?

What does a 4 piece ideler set do? I know nothing about pullies.

4lb lower or larger will require a larger alternator pulley.

4 piece Idler set replaces the stock idlder pullies with new, higher quality pullies as well as an Aux pulley

If you go with just a lower you won't *need* idlers. They do look nice though.

Also, and I know I am going to get flamed for this, I don't run an alternator pulley. I've run about 10K miles like this. Someday I will add one. When I had my kit put on my tooner at the time (who is a notorious dipshit) said I didn't need one. My alt my crap out tomorrow it may last another 2 seasons. Who knows??

Just a reminder though, maintain your idlers regardless of mods. This weekend I took my car out and noticed a squeak. I went home and took my stock idlers off and spun them by hand. They would rotate about 1 turn with moderate force. I cleaned them up and lubed them up with some bearing lube from my RC truck (very high quality lube). With about the same force they turn about 10 times. Big difference and it eliminated my squeak.

If I could do it all over I would have gone with a 8 lb lower to start with and no upper. That way you still get the higher boost level but theres alot better chance for no belt slip with the lower :biggthump

That's why I did it that way. It cost a little more than doing just an upper w/idlers but zero chance of slip. And it's more stealthy (if you're into that). You could still run with your pulley gaurd on and people would never know what's up unless they knew to look down and see the flying saucer.

That's funny ha ha I agree with ya I love the stock ones but that's the way I bought the car. I am currently biding on a pair now on eBay I hope I win. But surprisingly a lot of people have complimented my on them to each their own I guess.
