Cagnazzi and Gray Motorsports joining forces (1 Viewer)

If the comparison is what Warren said versus what Morgan said, the majority of the difference is likely the fact that Warren was running 2 cars out of his stable. The balance could've likely been simply the amount of R&D.

Having dabbled in the performance spring arena, I can tell you that there's a reason they're so expensive. The material composition required to make the valve train act the way racers need it to has gotten pretty exotic. To start with, the base material isn't readily available. Plus, the material is very hard, making it difficult to work with on the coiler and exponentially harder on tools than run-of-the-mill spring grade wire. Add to that the multitude of post coiling processes still required on the springs and you've got an extremely high price part, no longer than they last with the aggressive camshaft/rpm applications of Pro Stock and blown alcohol.

They could always go to a Rotary. No valve springs to worry about

At what point does pnuematic make more sense.

30 years ago in F1 LOL.

Pretty sure conventional (mechanical) valve trains are required by Pro Stock rules.

You beat me to it, Chris! LMAO!!!

Steel valve springs with the current valve train design have reached the point of diminishing returns a long time ago. Titanium is entirely too risky to use, so with the exception of a startling discovery of some sort of miracle steel, it is what it is. For applications like this, anyway.

All of this talk of Pro Stock valve springs reminded me of this thread from the days of way back. Still a good story.
