The Story
The Skunk Ultra BMF TLRC Camshaft System for H-Series engines is a roller cam and rocker combination that represents the latest in H-Series valvetrain and cam profile design. At the core of the system are lightweight steel roller rockers and billet steel camshafts with CNC precision ground advanced lobe profiles. Skunk2 Ultra BMF roller camshaft profiles open and close the valves much quicker than what is possible with an OE sliding-style valvetrain, which is key to improving power and efficiency. Designed to be stable at 12,000rpm, the Ultra BMF TLRC is the ‘missing link’ needed to open new levels of H-Series performance and efficiency.
Results will vary from set-up to set-up, but the real-world feedback we commonly receive includes: increases of +100whp, a broader power band that carries higher, a dramatically improved VE table, faster to the 1/8th, the ability to utilize larger exhaust housings and turbines. Racers switching to the Ultra BMF TLRC System have all experienced massive gains in engine efficiency and vehicle performance.
*Cam Oil Rail needs to be clearanced for cam lobes. Minimum clearance needed: .020
FEATURES:
Lightweight Steel Roller Rockers
Billet 8660 Alloy Steel Camshafts
Advanced BMF Roller Profiles
Higher Efficiency with Wider Power Band
12,000 RPM Capable
REQUIRED FOR USE:
Ultra BMF TLRC Rocker Set H-Series - PN 348-05-0500
CAM SPECS:
Intake Camshaft
Lift: 0.520"
Duration: 300° @0.1mm / 0.004"
263° @1mm / 0.0394"
257° @1.27mm / 0.050"
Exhaust Camshaft
Lift: 0.503"
Duration: 304° @0.1mm / 0.004"
264° @1mm / 0.0394"
257° @1.27mm / 0.050"
NOTE: 12,000 rpm spintron validation was done using the S2 ProXP springs, Skunk2 spring bases, and Skunk2 Titanium Retainers. Other combinations maybe be used, but results may vary.
