The shape of the front of the RED POWER piston head has been designed to further reduce the stress due to the impact with the PAD of the cylinder head also to R.O.F. high. The RED POWER head does not have the double sealing / centering O-RING, but has a small gap that decreases the contact surface with the inside of the cylinder, to minimize friction. The total height of the TopMax piston head is standardized to the size of the other piston heads on the market. The ERGAL and DELRIN insert for fixing the piston head on the piston is slightly shorter than the standard market size, in order to use the TopMax piston head on any piston on the market.

The RED POWER piston head, in the compression phase, exploits the Venturi principle, thus generating a more homogeneous compression of the O-RING for any configuration in which it is installed. The compression chamber is sized to allow an optimal compression opening time of the O-RING and to avoid that more power than necessary is not supplied in FULL AUTO mode, creating increases in the shot trajectory.

Usable on any configuration, from low-R.O.F. at high-R.O.F., we still recommend the use of the RED POWER head on configurations with R.O.F. above 25 bb / s, to take advantage of the early compression that derives from the position of the anti-vacuum holes. The STRESS-TESTS carried out on the RED POWER piston head have been carried out with springs higher than those required by law, so the product will guarantee reliability and performance even with more demanding configurations. For maximum performance, we recommend pairing with the TopMax piston and cylinder head.Compared to the WHITE piston head, in RED POWER the size and position of the radial holes is different to obtain even more stability, constancy and precision in the shot. IN PLACE OF THE THRUST BEARING AXLE, MOUNT A THICKNESS IN ULTRA RESISTANT DELRIN. THIS ALLOWS TO USE THE CT IN MAXIMUM STRESS CONDITIONS.
