RPM’S New Track-Focused CSR Special 350hp 996 Carrera-based CSR EVO is RPM’s most track-focused Porsche ever A more modern take on the modded 911 theme. RPM’s CSR EVO mixes track prowess with road ability and includes engine mods with longevity in mind. Look out for a full test in the October issue.
The restomods are coming thick and fast this month. Next up is a more modern take on the modified 911 theme courtesy of RPM Technik’s latest CSR model. Enter the new 996 CSR EVO, said to be RPM’s most track-focused Porsche to date.
Based on a 3.6-litre second-generation 996 Carrera 2, RPM says the EVO has undergone extensive re-engineering to produce a highly dynamic package targeted at customers who require out-and-out performance without compromising day-to-day usbability. Achieving that balance involves an extensive list of components and modifications.
First up, the revised suspension system is based on a bespoke version of KW’s Clubsport coilovers with custom valving and spring rates. To that are added CSR-specific corner weighting and geometry, adjustable lower arms and roll bars, and finally poly bushes. As for the engine, it gets the CSR preservation pack plus a Stage 1 power kit. Key components include hotter cams, flowed and ported heads, an induction upgrade and a centre-exit exhaust system. All told, power is lifted from the 320hp of the standard 3.6 to 350hp.
The preservation pack, meanwhile, entails a third radiator conversion, IMS bearing upgrade and a deep sump. Together, those changes address the most important weaknesses of the M96 engine in 3.6-litre format. Next up is the drivetrain. That benefits from an RPM-developed lightweight flywheel and clutch, the first application of CSR’s in-house mechanical limited-slip differential and a short shift mechanism with a modified throw and weight. Braking power comes courtesy of signature CSR orange four-piston calipers, CSR floating discs and high performance pads and brake fluid.
Visually, the EVO has its own character, too. The interior includes a subtle mix of CSR signatures and safety features, including a deepdish steering wheel, CSR tachometer, and CSR EVO gear lever. For driver comfort, a half roll cage is fitted, plus a driver harness, custom CSR harness bar and deep race bucket seats.
On the outside, the launch model is presented in custom Merlin Purple and sports a full aero kit. The new CSR EVO front bumper with aero vent and angled third radiator is said to increase downforce in combination with the CSR carbon ducktail and side skirts. Finishing touches include a lightweight carbon CSR bonnet, custom rear bumper with vented exhaust trim and colour-coded lightweight 18” OZ wheels on Michelin Cup 2 tyres. All in, the CSR EVO is said to be 45kg lighter than a standard 996.2 Carrera. RPM says the aim of its extensive development and testing has been to achieve “perfect track and road balance with the EVO.” As with all current generation CSRs, the EVO received its final shakedown and sign off by 1992 BTCC and 2008 Porsche Carrera Cup Champion Tim Harvey at Castle Combe.
According to Darren Anderson, RPM’s Commercial Director, “For the EVO we have concentrated on building our most circuit capable 996 CSR to date without reducing any of the character and day-today driver ethos of the CSR. The engine, drivetrain and suspension have been significantly re-worked and custom front and rear bumpers have been developed to complete the package. The feel and driver feedback from the EVO is all about performance. The bespoke CSR centre-exit exhaust not only stands testament to the unique engineering in this vehicle but sounds glorious and unlike any normal Carrera.”
For the record, the first 996 CSR EVO is chassis number 22 of 28 cars either built or currently in build by the dedicated CSR division of RPM Technik. For more information, head for rpmtechnik.co.uk.
