Divide the flow number by 8, then multiply that number by 7. If it works it was just a lucky guess.

Email Charlie I think he has the formula. Randy Malick may have it too.

This is very easy to figure:

Flow at first test pressure X the square root of the second test pressure divided by the first test pressure equals the flow at the new test pressure..

In your case multiply by .935 to go from 32 to 28 inches of test pressure.

I just use the Superflow conversion chart and it does not show 32"; (just 28", 30" and 35").

http://www.lindseyracing.com/LR/Parts/TGHEADS.html Scroll down, the SuperFlow chart is in there, you will have to wing it, as 32 is not in there as Randy said.

Why on earth would you have to "wing it"? All you have to do is multiply your flow numbers at 32 inches by .935 and you'll have your numbers at 28.
