Hey guys we have the 6 blade design Billet High PR Thumpers now ready to go. We are making them from 88mm -115mm in Billet. All wheels are designed for max pressure and flow, with slimmed hub lines. We can build them with Non-MWE and with MWE covers for the class rule guys. This is the next level up from the GT55, S500, S510 series units. A lot more power and a lot less drive pressure. Turbine wheels are 130mm.
