So I need a new alternator. My question is, which one? The 145A or should I get a 160A off of a police intercepted tahoe?

The only thing stopping me from the 160A is that I will have to change out all my wires to thicker ones so the alt. wont melt the wires and blow up my truck lol.

Let me know what you guys think

 

145A does just fine for me..
I am running LS1 fans
a transmission cooler fine, and an Amp, stereo, fog lights and headlights, and it doesnt even dim the lights when my 10's hit..

 

you need more power then...hehe...

 

I gather my '01 Suburban came with the 145A (based on what I've read here), and I have ZERO problems with voltage draw from the fans.

As for upgrading your wires, it wouldn't even be that much. A larger ground and a larger primary will only set you back an additional $40 and that is including a fancy gold plated fuse block and 200A fuse

 

the 160 amp won't melt any wires unless you're useing that much juice more than intermittently. If you can get it for the same price and with the same warranty, I'd go for the 160

 

LOL
More important things to worry about then how much I can push the 10's with
I just wanted something I can here over the motor

 

Im Also Gettin Lt1 Fans, So Will I Need To Get A Biiger Alt Too? I Dont Run Any Real Accessories Like Amps, Extra Lights , Etc. Also Can I Run Them With An Asp Underdrive Pulley? Options?

 

No u shouldn't need a bigger alt, not sure with the pulley though...

My stock alt runs things just fine.

 

My stock alternator runs them just fine too.

I was wondering though, has anyone tried to hook up one of those 1 farad capacitors to stop the dimming problem?

 

I have a 1 farad cap, but my lights still dim a bit. maybe I need to charge it
