I had one on my last 1983 RX7. That was the second stage that I built that car. I went with the 7" Camden on my large street ported 13B (carb).
First, the good:
The sound is awesome of a supercharged rotary. It provided the low end grunt that most rotaries lack. I first had it installed with a RB lightweight steel flywheel and had to change it back to a stock flywheel to get traction. It would break the rear loose even in 4th. The fitment was great, although I would recommend you replace the 4 intake manifold bolts with studs for ease of install. The serpentine pulley/belt setup is fantastic...far better than a dual belt pulley.
The bad: THE HEAT! At the time I had the Camden, I lived in South East Alabama...about 80 miles north of the coast. The summer days are brutally hot with temps and humidity being almost the same. I ran a brand new OEM radiator, new (not reman) water pump, and dual 10" pusher e-fans and it would still want to get hot. Water wetter made little difference. Thermostat, no thermostat, hollowed out thermostat....all made no difference. The Camden breathes the hot air from the engine compartment, compresses that (creating a hotter intake charge) so the heat was a constant that I had to watch. Cooler times of the year were never a problem. The only other thing is that the Camden seemed to run out of steam above 7000-7500 rpms. It felt as though it was being over revved, which rendered it inefficient. Just grab another gear and that was solved. The aggressive porting that I had on that engine really pulled hard till 8500-9000 though.
All in all, I think the Camden is a great product. As with any major power adder, many things need to be addressed. I already had my fuel system (fuel cell, Aeromotive A1000 pump, -10 supply lines and -8 return lines, Mallory 4309 regulator), so that was of no concern. My ignition was ready with dual Crane HI-6s and LX92 coils, RB wires, no ignitors (the ignition was hot). I ran a cooler plug due to the ignition being so hot, but it didn't seem to matter. Summer, I was just about watching the temp gauge more than the road.
Let me know if you want to know more.
