Crane HI6-R
Ordered it yesterday because I like the low minimum operation voltage... (7 Volts vs. 10 Volts on the MSD 6 AL).
Does anybody use that ignition box? Any experiences with it would be appreciated...
Hopefully, the install will be straight forward..
If anybody has experiences with the box and the install, any input would be appreciated...
I hope to be able to race my car without the alternator belt if I use that ignition.. (I have electric fuel and water pump).
That might give me a tenth or so at the track...

I run a Crane HI-6 on my 302 Z/28. I have it triggered off points but it can trigger with just about anything. The box is mounted where the radio speaker used to be so it is out of sight when looking under the hood but still gets ventilation. The instructions are excelent IMHO. The soft rev limiter works well and can be adjusted with a screwdriver and that is a very good feature. I have it set for 7500 RPM 
Probably don't need it but it is there. 
BUT...I apologise because you are looking for track experience and that I can not help you with, sorry

I have had one in my car for 5 years now. It works great. The rev limiter works very well. I have it set at 7000 rpm and have bounced it off many times. I have it triggered off the points and never had a problem. I wanted to see how well the rev limiter worked so I set it at 5000 rpm and just left my foot in it. It stayed right at 5000 rpm. It is a good unit.

Is anyone actually using the Hi-6R or just the regular Hi-6??
The Hi-6R is the racing version of the Hi-6 which is designed for lower voltage and higher RPMs...

The HI6R comes with a vibration mounting and a couple of minor differences. Mine is good to 9900 rpm. I doubt you are going higher. Check out Cranes website for the HI6DSR. Now your talking race ignition. With multi rev limiters and there is another one that has a retard in it.

Oliver - I have had the HR-6 for about 4 years now without a hickup. What i really love about the Crane system is the nice jacks. If you suspect the box of having a problem. You just pull the input and out put jacks from your car and plug them together and the box is instantly out of the system.
Using a deep cycle battery and no alternator might gain a little time. But then your hooked to a generator between rounds.

I'm not going to run without belt during events, just when I'll try to go for a new best ET...

You do understand that alternators use more HP as amp demand goes up? So if you go to the track with a big amp capacity fully charged battery the alternator HP loss is decreased.
I run a smaller damper pully and a larger alternator pully just to keep the ACC. items rpm down.
I also ran 12 gauge wire to the + on the Crane box - No brown outs

I'm not gonna mess with the pulleys... It shouldn't be neccessary for me to mess with the pulleys. When bracket racing, it really doesn't matter if I'm a few hundreds faster...and when I go for best ET, I'll just remove the belt...

For ignitions, I'll stay with my Accel 300+ as Echlin Corp has been in vehicle electronics long before Crane or MSD were around. I think MSD and their "pills/chips" SUCK!

Launched above 2000 RPM and spun (2.280 - 2.4 60' time)
I don't want to try slipping the clutch on launch considering that stock C5 clutches are POS and might not hold up to abuse.. Planning on going with a Z06 clutch when it's time to change..

I have been using the Hi-6 since I built my 406 and it has always worked well. The sequential rev-limiter is great as it does not induce the popping that the MSD boxes do. I am going to be getting the optional ignition control module for my box which lets me have a start retard, boost/map retard, switched retard, and high gear retard. It's a pretty slick little unit.
I mounted mine on the drivers side fender above the wheel well.
I am using the LX-92 coil.

Glad that everyone seems to like the Hi-6... so I'm sure that I'll be satisfied with it too!
