Tom, You are about right on snowmans intake temps, his turbo is sized perfect for 15 psi and 400 HP. right in the 80% range.
Snowman, remember a CARB is a poor mans intercooler, the fuel cools off the intake charge in the intake manifold a lot, on a turbo you set the A/F ratio for max HP first (11.0 to 1) then make it driveable after you know the amount of fuel you need for max HP. You need to control the cyl, temp because the fuel amount and the ignition timming effects all of this in the end. Only change your jets it get your fuel set for max HP then you can fine tune it after you know how much total fuel you need.
Did you up grade the fuel system? this needs to be done first.
