Which cam best suits my needs?

Piper Torquemax
Like the name suggests, this camshaft is profiled 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

Kent H180
We now offer the Kent 180 camshaft as an option on our camshaft kits for earlier Rover V8 engines with distributor driven ignition systems. The Kent H180 sits between the Piper Torquemax and Piper 270 in terms of driving characteristics, and is a great choice when you can't quite decide between the two. We have also found it great with Hotwire EFi systems with Lambda loop enabled, where the Piper 270 camshaft might give a slightly lumpy idle.

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 heavier saloons and Land Rovers which have been upgraded to stage 1 heads or beyond.

Piper 270i

The 270i camshaft has similar characteristics to the 270 detailed above, however the profile is altered slightly to suit a Rover V8 engine fuelled by an injection system, which require more intake vacuum than a carburettor setup to get the correct air/fuel mixture at low engine RPM.

Piper 285
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 especially recommended when using the 285 camshaft

RPi Advice

  • Never re-use your original tappets
  • Timing chains are normally badly stretched and will always need replacing
  • Push rods are low-cost and should be replaced if at all worn
  • Shim kits for setting tapped pre-load are available and essential for all work involving camshaft, valves or rocker assemblies
  • Rockers and rocker shafts should be inspected for signs of wear or breakage
