Just curious, always nice to see new ideas come out, wondering what the purpose is.
That's a good question Jacob. Its about control, lighter weight, better harmonics and less abuse of parts in the upper rpm (otherwise known as more power).
I had seen a few years back a couple of side by side videos of the "standard" valve spring vs the beehive. You could see the "standard" spring bouncing around a lot more and the top of the valve "shimmeying" while the beehive maintianed much better control. I can't find that one right now, so I'll have to post up a sales video to give you an idea of what I am refering to;
With starting to work the 16 to 1 engine, I took a look at beehives for our cars. I couldn't get Kevin (Kiggly) to make a retainer for ours (said he was just too busy with family stuff. I understand that but its too bad because he already has the springs. We use 4G63 springs in our engines for an easy upgrade) and I sure wasn't going to approach our buddy DCR for them (I know Kiggly's are expensive enough. I'd hate to see what DCR would want for them, lol).
So I did some researching and a buddy happen to mention that I should look at the numbers on the stocker 4.6 springs. Because if they worked, it would be a cheap alternative to.....well, I guess it would be our only alternative, haha
Agreed on the Crower springs etc, doing fine all along. But think of it as a titanium retainer vs a stocker. While the stocker will do fine, the titanium will net you a little bit more. I guess its about getting that little bit more out of the set-up.
