The lead actually reacts with the valve seat and valve face to form a hardened surface. After this has taken place no more lead is necessary as far as valve seat wear is concerned. A valve job will remove this hardened surface. Kevin, the current trend in $50 LEGAL fuel is the use of additives that ...

Relaxing the DC is going to reintroduce the now $45 a gallon exotic race fuels. They are good for 1-2 HP. It would seem much more practical to leave the rule as is. Most competitors are never going to have their fuel tested, they can use illegal unleaded pump gas if they wish. The front runners will...

So the rule is being changed to allow unleaded pump fuel? Ethanol in gasoline has a much higher DC value. This would seem to be a re-introduction of the "rocket fuels".

Here is a table of gasoline dielectric constants: http://www.ridgecrest.ca.us/~hideseng/dc_list.htm

Why are the fuel rules being changed? Have they been hard to enforce? Are they ineffective in preventing the use of expensive special fuels? What is the long term objective of the fuel rules?

Dave is right, the quality of the input is very important. This is a political process. You have to convince the CRB and Brd of your position. No changes just for the sake of maintaining tradition is not a strong position.

Jim The F1 teams manufacture and have certified there own models for individual drivers. I don't know if the need permission from the original manufacture. They have to meet the FIA spec which is based on the original HANS. You have to use a unit that meets this spec, but not necessarily the origina...

Butch is right. Without a spec and tolerance how does tech know if the horn is bent. What about bending it by hitting a curb? Learning and keeping up with how the rules are applied is a part of all racing. Its a moving target. Kevin...did you formally apply for the weight change? Maybe a thread test...

There is no consideration of brain energy in the design of the HANS. The body and the neck must move as a unit to prevent neck injury. Adding a damper is not practical. How much distance is available for the damping function before you cause a neck injury, 2-3 inches? The F1 teams build their own HA...

Your belts, if properly installed, are not going to fall off a HANS when used with any current SCCA formula car. Your upper body just can not move that much side to side. I would say this is the case with all new racing seat systems used in sprints or stock cars. There is no lateral body motion. No ...

Is it interesting that the HANS has been around since 1985 and it has only recently found acceptance. The cars must be much faster and the drivers much more safety conscious, but then they were pretty fast in '85 and we had J. Stewart and others on a safety kick. I guess we can thank Dale and the ta...

The HANS will work fine if you get the right angle for your driving position. You have to get the tethers as close to horizontal as possible, or parallel to the forces being applied. This is not always easy to do with all seats and headrests. In rear impact your head will spring off the headrest whi...

Derek Harding from S. California will be running. Yes it is a long tow, so we hope to do 2-3 other races around the Birthday weekend.
