Stage 4 - Drag race or radical street strip use. Rough idle. Requires upgraded valve train and ECU upgrade. 1500-8500+ rpm.

Stage 5 - Race. Rough idle. Requires ECU upgrade as well as upgraded valve train components. 2000-9000+ rpm.



DPR - F1 Touring Camshafts

DPR F1 Touring Camshafts are a result of years of racing touring cars, drag cars, rally, and formula cars. The profiles are proprietary and are specific to the nature of the required application of a given sport compact engine design. They are designed to provide optimal peak power, fuel efficiency for the given application, and the most usable torque throughout the entire RPM band. Cores are cryogenically treated, then machined to finished specs, then treated again to strengthen the surface metal, and properly orient the metal grain to fight metal fatigue and wear.

  Cams are available for most makes and models of bikes and cars. If a cam is not available for your specific make/model and application, send us the original cam, and we can have it re-ground to a custom profile! DPR Cams are the only cams with radiused lobes and Microlon anti-wear and anti-friction treatment.

Note: Honda B-Series VTEC Fitment Only! Requires Valve Train Kit and High compression pistons for maximum performance.


We've boasted about our DPR "Custom Subaru Cams" since 2008. Watch this video of a DPR modified Subaru WRX/Sti running the quarter mile in 9.40 seconds at 148 mph and get your own opinion of what they can do!!!

!!! Warning Race Use Only !!!

Due to the aggressive profile of these camshafts, we recommend that they are only tuned by a Professional Engine Tuner that fully understands their limited cam timing adjustment. Failure to comply with these limits may result in Engine Damage or Failure.
