Get one of these. It's got all the parts you need, and the larger hoses and fittings will allow the increased airflow you'll need to be able to cycle both the R/T and the Cyclone at once.
One thing to pay attention to, though. In the kit, there's a tiny cylinder made of aluminum with a hole down the middle. Install this cylinder inside
the hose that goes to the Cyclone. This stops excessive airflow reaching the Cyclone which could cause violent over-rotation issues. Also, it ensures that you feed buttloads of air to the R/T, which is a good thing.
