RenaultSport Clio 172 and 182 owners can now benefit from a proven, road-friendly drop in power upgrade that won’t break the bank!

The new upgrade from Belgian performance valvetrain specialist Cat Cams NV features a pair of billet steel 5502438 camshafts, which incorporate a revised design to specifically enable them to be used with the standard (remapped) RenaultSport ECU.

The full technical specification of the Cat Cams 5502438 profiles is here

Extensive rolling road dyno testing in conjunction with an ECU reflash has shown an impressive power gain of 18 bhp at 6250 rpm, with a torque increase of 10 lb.ft @ 5250 rpm.

The peak figures produced by this RenaultSport Clio 182 were a healthy 185 bhp @ 6500 rpm, allied to a substantial 164 lb.ft of torque at 5150 rpm. (NOTE: This test 182 already featured an ECU remap, so owners of standard 172 / 182 Clio’s should benefit from an even larger power increase.)
