It seems like it would be a very worthwhile investment for any rotary engine. It is basically a sealed canistor that you would fill with something cold like Ice water, with a fuel line spiralling from the top of the can to the bottom. You would plug your sending line to the top of the can..... then you would plug another line from the bottom of the can, to your fuel rail. What it does is it dramatically cools the temperature of the fuel entering your combustion chamber, increasing HP/Torque, and decreasing the likelyhood of detonation.
I don't know how drastic the deference would be on rotaries(especially turbo) but I think it would be a worthy of some investigation. Just a thought. Sorry for the Vague explenation.

Not many in this forum have a drag-only RX-7. You'd be better off trying this in the RACE forum.

What keeps it cool??? The water in your can would soon get to the ambiant temp, which is what the gas in the tank already is.

I heard of people using dry ice, not water though in these. If you dont understand hes trying to say you run a fuel line through this can to cool the fuel before it enters the engine.

It's really a drag-racing oriented thing. Chaneg the ice water between runs.

However, I guess you could run a pump and a small rad to cool the water temperature.

I've mentioned this before. You can do it w/ a coffee-can and dry ice.

It's good for short bursts, like runs at the drag-strip. It's along the same lines as icing your intake. All it does it cool the intake charge.

I would probably do these if I were REALLY close to a mark ( 15.02 or something ) but otherwise... I wouldn't even bother.
