| 500-525hp with good EFI tune on fuel only.
PPE 220/Edge stack wont get you close. Hot+2 maybe 460-480hp
You will need a lift pump
Stock IHI only make 30-31psi, after that it will blow up.

| So right know my turbo is at the 31psi level. What will happen when she blows up? Now I'm scared to death.

Dont waste your time upgrading your IHI for 550ish HP. Get a 66mm and make 600hp with cool egt's:cool | |

| Get rid of the LB7 IHI.
The downpipes suck and even if you put a bigger compressor wheel in it the turbine wheel will be to small and you will have high drive pressures. | |

debris usually get stuck in the intercooler
