I've heard similar cams (only about 5*'s off) and they have a nice rumble to them. by Marc Mon May 12, 2003 11:38 am, Post Do you know what the best lobe separation angle for your car engine is? It provides a spark plug with the high voltage needed for combustion. But, after comparing these two LSA based on a few mechanical aspects, such as maximum Torque, RPM, powerband, oil consumption, and many more, you will find the 106 LSA with better performance output. The taller lobe seperation will have a longer powerband but will have to rev higher to make the power than the lower lobe seperation! Comparison Table Between 106 Vs 110 Lobe Separation Angle. So, without wasting any moment, lets find out the answer. I think you are asking a lot of a cam . I will be running an Edelbrock Performer RPM, with a Quick Fuel 750cfm with a screw adjustable vacuum secondary; it's called the Pro-vac. by Kdub Sun Dec 07, 2008 1:20 am, Post I would have to say that your cam choice sounds like a winner to me. by 3V Performance Sat Dec 06, 2008 4:38 pm, Post Lobe Separation or Lobe Centers is another way of expressing the Valve Overlap, which was the term formerly used by cam manufacturers before industry standard verbiage changed. Typically, narrower lobe separation develops peak torque at lower rpm and widening the separation tends to build peak torque higher in the rpm range. Lobe Separation Angle "LSA " | Yellow Bullet Forums in some cases,, the average torque can equal out. Camshaft Kits - 108 Lobe Separation (degrees) - Summit Racing I'm surprized at these questions as well as some of the replies. " somthing to that aspect. The 114o lobe will add a lot more vacuum at idle. The 110o will make more power overall. 110 LSA) and Crane's #341191 (238/248, .563"/.587", 114 LSA), display considerably different characteristics. Torsion Beam Vs Multi Link: Who Wins the Battle? Lobe separation angles, he continues, are influenced by the camshaft grind. "Ninety-nine percent of cranking compression is dictated by static compression ratio and intake-valve closing point," said Comp Cams' Billy Godbold. Nitrous engines, which make plenty of power and torque, often run wide lobe separation angles to moderate cylinder pressures and temperatures. Lobe separations gives lots of overlap and lobe centers just happens when the grinder decides how the peak of the lobe will arrive on a specific grind by their tooling. Simply put, the lobe center of the camshaft controls where the power curve is applied. 106 LSA: There is an increasing chance of engine knock at the 106 lobe separation angle. My duration will be about 230 degrees. Simply put, the lobe separation angle (LSA) is a measurement of how the intake and exhaust lobes are phased with each other. The piston and cylinder damage possibility is pretty low at 110 LSA. Do you like to go fast? Compression willl be 9.75:1. Mistakes that weaken a supercharger's performance . Cam Advise - 332-428 Ford FE Engine Forum If you shift at 7500-7800 add 4-6 degrees to both intake and exhaust and spread the lobe separation to 108-110. Thanks. *If you do not have enough vacuum, you can in some cases install a vacuum canister or reservoir, which works by storing the peak vacuum in the reservoir. The lobe separation angle in a natural car engine conveys a considerable impact, especially regarding the maximum torque. What Is the SBC Header Bolt Torque? Brul slid the 113-LSA cam, the widest of the test, into the engine's heart and set about putting all the pieces back in place. Noah knows a lot about whats happening in the car industry with the latest piloting productions thanks to his professional experience.
