I don't have a G-Tech, Bob. I doubt I'd get one since basically I don't care enough. It is what it is and if I can weasle an allowance to hit a drag strip I'll find out. Otherwise, if/when I let me sensibilities slip and dice it with somebody on public roads, I'll report the outcome.

I did ask my fabricator buddy who has built some racecar chassis and cages/roll bars to think about what a removable rules-compliant roll bar would look like.

I think I have "apps" on my iphone that can give me G-Tech type info. One is "Harry's Lap Timer" and I just looked at that and it seems to do all that's required. I also have Bosch "Light 'Em Up Dyno" but I'm not sure what it can do.
