The Thunder 330 is our latest effort to achieve performance perfection. The Thunder 330 was designed to handle multiple fueling upgrades and comes equipped with an extended tip 62mm compressor wheel and 6 pad 270-degree thrust bearing. The Thunder 330 utilizes the 74mm turbine wheel and has an appealing compressor housing. The Thunder 330 uses a .80 A/R exhaust housing in which we modify the angle of the exhaust nozzle, maximize the wastegate ports, and enlarge the wastegate chamber for full wastegate travel. The Thunder 330 can support over 600hp and is the best all-round performance towing turbo on the market.
