The flagship model of SPower’s “魂” (SOUL) series is entering the world of RC high‑speed machines with the new factory hand‑modified 1/8 On‑Road racing engine: the P7HP EUii.

Based on the renowned OS Speed Euro II on‑road engine, Spower has taken performance to the next level with a series of precision modifications. The 7‑port Euro II–spec cylinder and piston now feature a redesigned layout, including cooling holes at the bottom of the exhaust port, paired with a newly engineered crankcase.

Every port has been hand‑modified by the Spower design team to maximize efficiency.
The strengthened DLC‑coated crankshaft now includes three tungsten counterweights, delivering stable idling and lightning‑fast RPM response with every throttle input.

The engine also comes equipped with Spower’s newly developed 1/8 On‑Road Boost rear cover plate, ensuring exceptional stability across the entire RPM range—from blistering top speeds down to low‑speed transitions.

A new racing‑inspired cooling head, produced with advanced printing technology, gives the engine a striking, colorful appearance that integrates seamlessly into any high‑end setup.

Paired with the factory‑recommended combination of the latest OS MR05 exhaust manifold and EFRA 2196 pipe, the P7HP EUii delivers tremendous power along with outstanding fuel efficiency—perfect for all your 1/8 on‑road racing needs.
