The PDR camshaft upgrade is primarily designed for towing and daily driving. This cam will also work for trucks that see occasional drag racing and sled pulling. It features higher lift, longer duration, and better lobe separation. These improvements have shown a 30% increase in air flow during flow testing on the bench. Best of all the design is mild enough to not require fly-cut pistons or other modifications.
Typical improvements reported by many who have installed this cam upgrade are:
Longer HP & torque curve
1-3 MPG increase in fuel economy
100* drop in EGT's
Reduced turbo lag, faster turbo spoolup
Improved throttle response
Approximately 20% reduction in smoke
Our brand new marine cams start from a semi finished core, custom made to PDR specifications. The core features the cam lobe for the 12V lift pump.Each cam is checked and inspected, then precision ground to PDR specifications. This cam can be used in a 24V grind and allow a 24V engine to adopt the 12V style lift pump. Each kit includes a: PDR camshaft, gear retainer, and bolt. The kit does not include lifters (sold separately).The new marine cam is designed for the 1989-02 5.9L CTD only.
The marine cam shaft uses a retainer and bolt design, this stregthens the gear end of the cam shaft and decreases the chance of having the gear "walk" off on high HP applications.
The retainer bolt ties into the second journal in the cam shaft thus increasing the torsional strength of the unit.
This new marine camshaft is recommended for high HP trucks (over 450HP) but can be used in trucks with under 450HP.
A PDR camshaft can be installed in house or customer installed. Installing a new camshaft is a 10-12 hour job and should be done by a professional mechanic. An experienced do-it-yourself-er with good mechanical skills and tools can complete the install. Some special tools are required for removing the lifters.
No exchange or core charge on cam shaft applies.
A $75.00 refundable core charge will be applied to the cam shaft shipping box.
New or re-ground lifters can be used with this cam shaft.
