Titanium Valve springs

Oddly they are, I checked , confirmed and double checked (with the NHRA), since there is NO mention of allowed or disallowed material, its allowed......

Hey Mike,

You are correct about the weather. As usual, it SUCKS this time of year. I went to Cincinnati yesterday to pick up my son from U of C and the wind was really tough. It was like driving a B/ED at Indy in a 20 MPH cross wind when you get past the grand stands at half track. HANG-ON!!

Hey Aaron,

I appreciate the respect of Mr. Merrick, but racer to racer, please call me Gary. Even if I am old, bald, and fat, my Dad (rest his soul) was Mr. Merrick. <G>

As far as getting back to the topic, good luck with the valve springs.

I don't know of any Fuel Teams still using Titanium Valve Springs. On Jim Head's Car we found they were either good or bad, no in between. They either broke on the first run or they lasted a while, but we checked them every run, and they'd check ok, then break. We couldn't "see" them going away with loss of pressure. And with a nitro car - that's bad.
We use Manley Springs, as do many teams, of course I cryo and rem finish them. But seeing we ran the same springs all year without a broken one, that speaks for itself. And our installed pressure at the seat is around 600# and 900 - 1000# open. Pac Springs are the other spring of choice in Fuel. I've been told, Pac uses Cryo in its manufacturing process, therefore it's done when you buy them..(trade secret)...ha. JB
