I applaud Steve Weinstein and his com. efforts to revise the slalom rule, however I strongly disagree with considering after market ignition modules as a performance upgrade, counting as 1 mod and possibly bumping people into full fledged modified.

Basic Crane and MSD system do not offer any performanace improvement over stock ignition, they are only a reliability upgrade. External Rv limiter and timing adjustment ... maybe... but not a basic ignition module.

If we allow HE ignition in stock class on non HE XJS, why forcing V12 E-type owner to keep their unreliable Opus module. electronic ignition may (and that's a stretch) make a difference vs points on an 6 cyl E-type but not on a V12.

I did some 0-60 test before and after installing my MSD a few years ago , and did not observe any change. it is purely a reliability upgrade.

I think that's a mistake...

btw, whatever happened to the experiment to run the Slalom in a different order. I was under the impresson there was a strong interest in that last year to balance tire wear?

I installed a MSD basic on Silver and the car seems to start a little quicker, this was severalyears ago.
Re tyre wear ( tire wear ) surely people are aware that tyres are supposed to be ROTATED from one corner to the other, if rims are the same size then surely rotating the tires is a simple solution.
Slalom racing wears out tyres, if you cannot stand the tyre wear stay away from it, that is the same as buying a house next to an airport, then complaining about the noise from the Jets.

Pascal,

Sorry for the delay in responding, but I've been on vacation.

Your comments on the MSD and Crane ignition systems is noted. The problem, as I see it, is distinguishing between those after-market systems that enhance performance and those that do not. In making a major revision to the rules, we had to look at the big-picture times first. Hopefully, next year we will be able to get down to the closer issues and fine tune the rules a bit, when we see how things shake out this year. Hopefully, you will raise this issue again next fall so that we can examine it in more detail next winter.

As for running the course in a different order, again, with the major re-write, undertaking that change seemed too radical. I also think it needs a bit more testing. The problem I've seen is getting people to understand the sequence and, as importantly, keeping track of what someone is doing when running it. The current format is easy to follow, from an observer's point of view, and therefore easier to determine if someone is "off course" and therefore DQ'd. The idea is not dead. It's just not happening for this season.
