RPM’S NEW TRACK-FO­CUSED CSR SPE­CIAL

350hp 996 Car­rera-based CSR EVO is RPM’S most track-fo­cused Porsche ever

911 Porsche World - - News And Views -

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, Ims­bear­ing 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 deep- dish 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.
