The French Connection: Turbosmart BOVs and Wastegate Actuator for Renault Clio RS

Turbosmart - Engineered to win

The RenaultSport Clio has built a reputation as being one of the most fun-to-drive small cars money can buy. The latest iteration of Renault’s pocket rocket introduced turbo power to the Clio RS for the first time, and Turbosmart have been working to give the turbo Clio a boost. The result is Turbosmart’s Kompact EVR07 blow-off valves and IWG-75 Internal Wastegate Actuator developed specifically for the Clio RS.

Turbosmart’s new Kompact EVR07 Dual Port and Plumb Back blow-off valves for the Clio RS replace the Clio’s standard plastic bypass valve with a billet aluminium unit, designed with performance in mind. The standard valve can bleed boost, and if you’re chasing more power, it will struggle to keep up. The plastic construction means that it becomes brittle over time, and can eventually crack, causing significant boost leaks.

You’ll have no such problems with Turbosmart’s Kompact. Machined and assembled in Australia, the Kompact provides race-bred capability in a compact, bolt-on replacement for the Clio’s factory BOV. A lightweight piston, precisely matched to each individual valve body, ensures excellent response and reliability. Because of the fine tolerance between the piston and bore, the Kompact does not need an O-ring between the body and piston to seal the BOV. This enhances response, reduces required maintenance and improves long-term durability.

The product includes a Turbosmart Boost Reference Adapter, which provides access to a boost reference without any destructive methods, such as tapping into the manifold. This means the modification is completely reversible, important when the time comes to sell your car. The Boost Reference Adapter has two pressure ports, allowing you to run a second manifold pressure operated accessory such as a boost gauge. The Boost Reference Adapter is also available separately.

For those seeking some extra kick from the Clio’s turbo throughout the rev range, Turbosmart’s IWG-75 Internal Wastegate Actuator helps the turbo reach its full potential.

The Clio’s standard wastegate actuator provides a relatively weak boost curve, with slow boost build up, and it fails to hold closed as the revs rise, causing a drop-off at the top end. Turbosmart’s IWG-75 for the Clio RS is performance-focused: it has stiffer actuator springs and a larger diaphragm, which helps the wastegate stay closed when it should – meaning boost builds earlier in the rev range and holds on all the way to the redline.

The result is power gains throughout the rev range, but a serious boost in the ‘seat-of-the-pants’ feeling that makes the car feel faster in everyday driving. The IWG-75’s bulletproof billet construction is combined with a versatile locking collar design, so it’s easily serviceable and customisable.

As a bolt-on modification for the Clio, the IWG-75 is an awesome ‘bang-for-buck’ power boost that all owners should consider.
