The 104 had a distinct torque and power advantage from the get go while the 110 pulled ahead toward the end of the rev range. Jump to Latest Follow ... Fifth, while a narrow lobe sep may make a tad more mid a wider can maintain power into the top end. I should've went with a 110/112. Do you like to go fast? ... 3.75" stroke= 108 LSA 4.00" stroke= 110 LSA 4.25" stroke= 112 LSA 4.50" stroke= 114 LSA I can see exactly where his theory is coming from. ... Bad idea in my view. Well get out of that stocker and build a hipo motor for your VW. ... Lobe Separation (degrees): 110 Intake Valve Lash (in): 0.016 Exhaust Valve Lash (in): 0.018 Computer Controlled: No Also, the jump in manifold vacuum between the 104 and 110 grinds is pronounced, especially Anything with a 112, 113 or 114 degree lobe separation is great for blowers and nitrous. Alright, I bought a hyd. Can you use a performance cam with a 110 or a 108 … Hot street camshafts usually have 110- to 112-degree LSA, while high performance and racing camshafts will often run between 105 and 108 degrees. Although both wide (112-116) and narrow (102-110) lobe-separation angles do have some effect on overlap, it's still possible to get tons of overlap with a very wide lobe-separation angle. The lobe separation angle is a comprise of what the engine needs depending on the compression, combustion chamber, rpm, engine size, head volume, and many, many other variables. If you advanced the 110 LSA cam 4* to a 106 installed center line (ICL), the 110 … lobe separation angles. 108 vs 112 lobe seperation. If you tighten the lobe separation angle from, let's say, 112 degrees to 108 degrees with no other changes, that will increase overlap, making that little triangle area larger. Although both wide (112-116) and narrow (102-110) lobe separation angles do have an effect on overlap, it’s still possible to get a lot of overlap with very wide lobe separation angle cams. A camshaft consists of intake and exhaust lobes, and a key consideration when designing a cam is the lobe separation angle, sometimes also called the lobe displacement angle, or lobe spread. The basics of what you want in a nitrous (or supercharger) friendly cam is a wider lobe separation than what most “performance” or “race” cams have. 106 LS vs. 108 LS vs. 110 LS cam for 383. The dyno plot however, shows how different each cam really was. All specs identical, if you had a cam on a 110 lobe separation installed at 110 intake centerline, it would have less compression than a 108 lobe separation installed at 108 centerline. Effect Of Changes In Cam Timing And Lobe Separation Angle The following tables illustrate how variations in lobe separation angle and cam timing will effect the behavior of the engine in which the camshaft is installed. ... A smaller lobe separation increases overlap, so a smaller lobe separation angle causes the engine's torque to peak early in the power band. Well I didn't want those because to get lope out of a hyd roller you either have to 106-108 or you have to go BIIIG duration. It’s the scavenging effect of the high velocity exhaust gases rushing out that pulls the fresh fuel/air charge into the chamber.
