Nitro Star F4.6 V2 Monster Truck Engine w/Pull Start by HPI Racing
This product was added to our catalog on March 14, 2014.
This is the HPI Nitro Star F4.6 V2 Pull Start Monster Truck Engine. This engine is the stock replacement for the HPI Trophy Truggy and Savage X 4.6 vehicles. The F4.6 is the powerplant responsible for the immense speeds and raw torque in the Savage X 4.6, and now it's available to fit into any Savage or big-block monster truck! It features all the race tuning you could ever want in a big-block monster truck engine, fantastic good looks and plenty of attitude! With 2.9 horsepower on tap, it really is true that there's no replacement for displacement!
With 8-port race tuning, you get a huge powerband through the entire rev range, all the way up to 32,000RPM! The composite 7.5mm carb is heat-resistant for consistent tuning as the engine warms up. The F4.6 V2 also features a redesigned crankcase and heatsink with larger heatsink fins for improved cooling. This design also makes the engine 37g lighter and 12mm shorter. An updated pullstart utilises a one-way bearing encased in a large 14mm hex for increased durability.
