After calling around for pulley sets, I decided to use LET. Erick is a great guy who answers the phone everytime you call and answers all your questions. The best part is if he doesn't know something he states "good question I don't know, but I'll find out". His pulleys are a little more money but they are a fluid balanced design vs a hard rubber dampener design of the factory one, which should eliminate the potential problem of the rubber dampener falling out and causing a misfire code. After considering my three choices of 178/181/185, I chose the 181.

 

What were your reasons for the 181? What are the biggest differences between the 3? Pully virgin wants to know! Thanks.

 

Haywood, 178=3lb boost 181=5lb boost and 185=7lb boost. 185 will require ECU remap and puts the ECU outside of it capabilities in stock form. 178/181 will run within ECU capability and you can reprogram ECU at a later time for optimum HP/TQ. You can still run the 185 it's just that the ECU will start to retard timing to correct for that much additional air. I hope that made sense.

 

hm.. wondering how needswings intake + plus 185mm pulley + an ecu tune would work out...

 

Correct - but only above 5000 rpm. (per Erich)

Still - you will need to tune with the 185 pulley installed

I will let you know how the 185mm pulley + ECU tune + sl55 intake works out

 

BrianBrave, are you going with the complete SL55 set-up? I though someone said the bigger air boxes don't fit on the SRT cars, at least that was the last info I got from the search.

 

why not go with the needswings intake?

 

Not true - just need a small adjustment to make em' work and feed all the air you could need.

To expensive and I don't like the look - and if I did I could make my own for less with off-the-shelf parts and the local powdercoater. Lots of threads on this forum on that.
