I have a stock 5.3 with an Ls6 cam, Comp 918's and ARP rod bolts with an intercooled Maggie. 112 I believe. I am currently running a 3.2" pulley and its making about 7#s or so. I am hoping to go to the dyno for a tune next week and would like to get up to around 10#s before I take it. Anyone have a recomendation on pulley size for my combo that would yield about 10#s? BTW no meth.
Thanks

 

Rule of thumb is about 1 psi increase for every 0.1" drop in pulley size with the Radix. But remember, as you pulley these down, heat goes up. And remember, boost is a measure of resistance, so you will lose boost with LT's or a cam with more overlap, but you will be making more power.

 

Thanks. I guess about a 2.9" pulley should get me there. Maybe I'll just go with a 3.0". This setup is in a mud truck and I have the exchanger mounted in the bed with two small but badass e-fans. However I'm not sure what IATs are gonna look like until I take it out and really beat on it. What IATs are considered ideal for my setup? Around the house it seems to be in the 120 F range, but that is on pretty short trips. Thanks again!
