How to Destory a Thread ...was...The Truth About Valvesprings!

And thank you...

for yet another content-laden post!

That's the FIAT MultiAIR engine...

and it's getting engineering kudos all over! But then, I don't think upgrading to them will be a simple swap......


Oh, and from SuperTechs website (to check the press releases, click on NEWS in the lower left corner of the home page)

Dated: 8/20/2009

SUPERTECH's New line of Beehive spring and kits has hit the warehouse. After much demand for them we are starting with a few application, however we have others in R&D.

The benefits are:

1) Beehive springs have smaller top coils and retainer. This means that the alternative moving mass (weight) of the spring and retainer are lower so you can run at higher rpms or you can lower the pressure of the spring for the same rpms.

2) The beehive spring has a variable rate. The rate increases as the spring is compressed and the lower coils that have a lower rate start binding before the top coils with a higher rate, do. Since they have a variable rate, they also have a variable natural resonant frequency that is changing constantly as the spring is being compressed.

A single cylindrical spring has a defined natural resonant frequency that may fool the operation of the valve if not well designed to that application and a Dual spring has two defined natural resonant frequencies that help dampen each other if well designed, but is heavier than a single spring.

Our Beehive springs have also been manufactured using high quality chrome silicon vanadium oval shaped wire for optimal distribution of the wire stresses and better durability.

So if this is Lucas tech, SuperTech, Ferrea, Comp Cams, Crower and on and on are really screwing up big time! Hay folks, it's time to get ON the bus! It's leaving the station!

So, let me get this straight.....

while you've been crapping all over the offering of Beehives using PAC springs WHILE you were working to get them yourself? That's freakin' priceless! Why not say "Yes, they are good tech, but my supplier doesn't stock a good fitting for the MINI yet."

FWIW, it seems that many of the companies are offering the PAC Racing spring. They have the ovate wire and the tech down. It's just a question of which spring for what app.

Glad you decided to get on the bus.

I read you posts...

I read you posts. Including

you just said that all that stuff about they why's and the theorys about thier improved engineering didn't matter... While you were persuing Beehives yourself.

You just said that what works on a V8 has no bearing on an I4, even though an I4 is just half of a V8... While you were persuing Beehives yourself.

You say that you have been going after Beehives from SuperTech for over two years, and NOW it's official? the press release was from August 2009...

You say that you only offer the best tech on your parts, and then igorned that you could have sourced springs direct from PAC Racing for a long time...

Jan, this one is for the books. You didn't have to slander by implication and just stuck with the "Beehives ARE good tech. I'd love to see more data" or "that article on valve train technology has some good information, I loook forward to when all the technology is available optimized for the MINI" and we would have been in complete agreement. Most of the pissing contest would never have happened, we would have had a more constructive conversation, and then when your product was ready, you could have offered it to the masses.

Instead, we get pages of craap; dilution of technical information; the standard inflamed pissing contests... All for what... To learn that you're working on the very same tech that others are offering.

Great....
