Peach blonde Ale... HUGE ABV

I'm brewing a peach blonde ale in bit and I was curious to see how much of the fructose in the peaches would effect the OG and FG. After some research I found that the fructose has a PPG of 46, plugging that into a calculator that would give me a OG of 1.167 and a FG of 1.043. Is this right?

Recipe:

12lb 2row
11lb peaches
1.25lb Honey malt
.5lb carapils

WLP005 with 74% attenuation

Peaches will be going in at flameout

Thanks

Nevermind... figured out where my numbers were off.

What form of peaches are you using... Also I assume you'll make a starter for the WLP005?
