Turning cake flour in to High gluten flour

I'm sitting on about 40 lbs of cake flour that has a protein content of 8.2 and I would like the try make it 14%. At what percent of the total weight of the cake flour should be vital wheat gluten in order to make it that high. I am horrible at math.

And I use Bob's red mill vital wheat gluten which is 75% gluten

about 3.8 lbs if I've calculated it correctly

40 * 8.2% = 3.28 lbs gluten

3.8 * 75% = 2.85 lbs gluten

43.8 * 14% = 6.13 lbs gluten

6.13 / 43.8 = 0.14 = 14%

Thank you @Pepijin. So let's say I just wanna have a total weight of 500 Grams flour. How much vital wheat gluten would that be?

collapse;width:300pt">

	Gram	% Gluten	Gr. Gluten
Cake Flour	456.59	8.2%	37.44
Vital Wheat Gluten	43.41	75%	32.56
Total	500.00	14%	70.00

To calculate this*:

You need 'x' amount of Cake Flour and 'y' amount of Vital Wheat Gluten.

x + y should be 500, so y can be restated as 500-x (since x+y= 500 => y = 500-x)

Now we only have one unknown we can solve for x; fill in the values for x to find y.

x*0.082 + y*0.75 = 500*0.14

x*0.082 + (500-x)*0.75 = 500*0.14

0.082x + 375 - 0.75x = 70

305 = 0.668x

x = 456.59 = 456.59 gr. Cake Flour

y = 500 - x = 43.41 gr. Vital Wheat Gluten

*or use solver in Excel

You can also use Wolfram Alpha to calculate these things for you. Click

The notation here is x * 8.2% + y * 75% = 500*14%; (x+y)=500

'x' is the Cake Flour
'y' is the Vital Wheat Gluten and in this case
(x+y)=500 is the restriction that Cake Flour and Vital Wheat Gluten should total 500 grams.

Perfect. Thank you very much
