Which A/R will be best for me on this turbo??

[Foster#17]

Hi everyone, I currently have a BD S366/80/0.80AR turbo. I am in the process of getting the piping rounded up for twins with that turbo and I am ready to order the other turbo! I will be using a Borg Warner s488 with 96/88 turbine wheel. Now my question is, What A/R will be best for me? I can get it with a 1.10A/R or 1.32A/R but im not sure which one? I am shooting for 1000+hp. I daily drive the truck and tow pretty often! Any help would be great! Thanks!

That's a big compressor for that turbine. Don't go any smaller than the 1.32ar. Personally, I'd step down to the s484 or step up to the s588sx.
