Check your helmet

[crossbonesdennis]

It looks like NHRA is dropping the Snell 2000's next year. That means your helmet will have to be a 2005 or newer.

Another stupid rule, just like new belts being required every two years.

You're supposed to get a new helmet every 5 years anyway. The linings don't last forever.

How can you tell if you distributor is "Locked out" or not? What advantage do you gain either way?

Easy way, hold the cam engagement (small end of distributor), and try to turn the rotor, if it doesn't turn, timing is locked out. Some people feel that it eliminates a possible run problem.

Easiest way if it's still in the motor is to grab the rotor and twist it liked you're trying to advance and retard it. If it moves more than a 1/4 inch then it's not locked out, if it doesn't it is locked. The best way to describe any advantage would be to say that while you are making your pass distributor timing can fluctuate several degrees and cause a significant difference in ET's and performance. By locking down the dist. you eliminate that element out of the equation.

I will new to racing next year and want to know if I need a snell m rated or a snell sa rated helmet. I have s10 that will probably run at best mid 10's. There are no power adders on it. Any help would be appreciated.

[crossbonesdennis]

Either one will work. Snell M tends to be less expensive than the Snell SA. The main difference is a Snell SA is fire retardant and the Snell M isn't. The SA will have a yellow chin strap. A M is usually DOT rated also. A SA isn't. M's usually have larger eye ports for better peripheral vision. If you were to run 9.99 or faster you would need a full face helmet.

99.99% of the racers (Jr dragster to Jeg's super quick) I've sold helmets to choose the Snell M. I wear a M in the altered. My dad and brother also wear m.

If you have some time to kill, here's a good article on helmet ratings.

If you run fuel, or a center steer car with the engine in front, no floor over the transmission, you need the SA helmet.
