Stock KA-T's with proper tuning, and fuel can hold 350, Dennis from Unstable Hybrids has been running 15 psi and 350hp for a couple of years now, no problems. Your biggest killer is the KA timing curve, you will need something to control your timing otherwise it will pop. We generally run a MSD6BTM on our KA-T's to give the ignition system more voltage, and a boost refrenced timing retard. A good tuning option is the Greddy E-manage, works like the SAFC2 but unlike the SAFC2 the emanage can control the timing just like the MSD unit can.

What are the specs of the turbo, exhaust and compressor AR? I was running a T3/T4 .48AR 50trim making 238 at 6 psi, running my old Holset of a Cummins Disel at 12 psi I made 342, we did another KA-T with a T3/T4 .63AR 50 trim, and it made 296 at 10psi. So number vary depending on the turbo size. What manifold, fuel, management you using?
