Which cam best suits my needs?

Piper Torquemax
Like the name suggests, this camshaft aims for torque at the bottom to mid rev range, making it the perfect choice for four wheel drive applications such as Land Rovers and Range Rovers (especially if used for towing), as well as heavier saloons such as the Rover P5, P6 and SD1 which are still on standard heads

Piper 270
A power increase in the mid rev range with a good increase in usable torque to boot, the Piper 270 is great for light 2wd cars in standard form such as MG B's and Morgans, or saloons and Land Rovers which have been upgraded to stage 1 heads or beyond. Those of you with automatic gearboxes on standard engines will also find the Piper 270 suitable, as the slip of the torque converter naturally pushes the RPM of the engine further to the middle, where the 270 comes into its power band. ECU remapping is recommended when using the 270 camshaft, please see the fuelling section of this website for more info.

Piper "Storm"
This is our stage 3 camshaft, bespoke to RPi Engineering. Set up for more power at the top of the rev range, while still keeping a smooth idle and driveability at low revs and low speeds and no noticeable loss of torque. Stage 1 or above cylinder heads and ECU chipping are recommended when using the Storm camshaft

Piper 285 
The power band gets shifted even further up, please contact RPi to discuss this camshaft before purchasing.

RPi Advice

  • Shim kits for setting tapped pre-load are available and essential for all work involving camshaft, valves or rocker assemblies
  • Never re-use your original tappets - doing so will cause accelerated wear of the camshaft
  • Always inspect your oil pump gears, and replace them if there are signs of scoring or damage
  • Push rods are low-cost and should be replaced if at all worn
  • Rockers and rocker shafts should be inspected for signs of wear or breakage
