    Other than the start, what speeds are driven in an EMod prepared car on a Solo course? Generally what's the slowest one would expect to drive? What's the fastest? What's the average?

    In other words, how do you gear an EMod car for Solo?

    It depends I suppose, my car will go zero to 85 in 3rd gear. EM torque is so cool, and I'm too lazy for shifting. I would aim for gearing that works up to 80 and still gives you some pull out of a 25 to35mph turn.

    I generally run my CM car in 2nd and sometimes 3rd. The low end of my 2nd is around 38mph(80% of max power). Since most EM cars make up for less than excellent suspension(CM) with lots of power, you will probably need to slow to around 30mph. To really figure out the gearing you would need a dyno run for your car(I have no idea what motor we are talking about here). Let us know what you figure out.

    What top speeds do you see in CM?

    Can't speak for EM either, but I can tell you that 30-80mph is a good working range to look for in FM. Given that EM is more power & weight, you're probably going to want a slightly larger window as you'll be going slower in the slow parts, yet faster in the fast parts.

    70 mph is a very fast autocross in any class.

    x3 on the 30-80mph range. I have 82mph in 2nd and have never shifted to 3rd on real course or because I was out of speed. I have shifted a few times to try to pass sound (before i added larger mufflers) and was all over 3rd at the recent Gateway Road Course tour, but the speeds there were not normal and uniquely suited my cars strength.

    Thank for everyone's replies up to this point.

    I contacted Jeff Kiesel via Email and he responded:

    It's all dependent on how fast the driver is. The other factor is chassis set up. Our car is geared to top out in second at 80mph

    Not to quibble but top speed is 78 mph. We have plenty of low speed torque to pull out of most autocross turns nicely.
