Answer 1

Go buy cream of tarter or risk messing up your cake.  I know baking powder is a combination of cream of tarter and cornstarch, but a chiffon cake is very delicate, so I would be afraid to suggest this substitution, but if you want to be brave.... Also, you can substitute all purpose flour, but cake flour usually makes a more tender product.

Answer 2

for the cake flour you can use  

  1 3/4 cups all-purpose flour

   1/4 cup cornstarch

This is equal to 2 cups of cake flour

Substitute the cream of tartar for an equal amount of lemon juice or vinegar. The amount for substitution should measure about 1/8 teaspoon per egg white.
