Thanks! That cam is interesting because of the big duration split between intake and exhaust. I'd think if you're running headers and a good exhaust system you wouldn't need so much extra exhaust duration.
I agree.
Yes, the LCE Pro Torquer profile is interesting. I don’t fully understand the design?.... my lack of knowledge.
It has a large split duration – 12 degrees. Why? In my early research days, I was always confused (uneducated) about the cam specs that LCE published compared to the other 22R aftermarket cam suppliers.
The LCE ProTorquer profile indicates a 4 degree advance in total cam timing.
The Schneider 244-50F has a 14 degree split, but indicates straight up cam timing degrees.
Schneider offers two Lobe Separation Angle options, one for carb and one for EFI. The EFI LSA is 112 degrees, the carb profile is 106 degrees.
For Peak HP, in the Engine Analyzer, the Schneider 210-216 out performs the CC252S at 5,000+ RPM producing 7 more HP (132 HP), and only 2 more HP (130 HP) at 5,000+ RPM above the 261C. The LCE Pro Torquer shows 117 HP at 5,000+ RPM.
For the 22RE, if a split duration profile adds performance – torque or HP, specifically for the EFI, why didn’t the Toyota engineers design it in?
Why does Schneider have a different LSA for the 22RE?
After emailing several cam suppliers with questions, only CompCam support has responded.
