Cheepy Three-Sixty build

I think in a standard compression eng, (7.5 to 9.4) factory eng, has no place for gap-less ring. aka waste of money.
When you start turning past 6000 rpm......(.actually probably more like 7000 rpm)and have to use racing fuel/Methanol.....(because you have compression!!!!) This is were gap-less ring could shine!
I realize these/this, are builds on the "cheepy"
RAMM, just how much HP can you expect on a factory build? Because most of these kinda builds will have stock to less then stock(318/w 360 head for an example) compression.
My guess would be 5Hp at 5500 rpm........................ I know the "selling" point of these ring are like 25 Hp but i don't think it was was a figure that can from ANY eng in stock form.
An i wrong?
