Pacs 1207x dual valve spring is part of their rpm series spring line up, and it has a max valve lift rating of .700quot this is an excellent setup for any customer running aggressive lift with their hydraulic roller camshaft, as well as those running factory gm rocker arms with a low-lash solid roller camshaft
The 924 weighs a little over 142 grams with an install height of 1.8 plus another 10th of an inch on top for the retainer. setting the spring tester to 1.9 inches, the amount of preload this spring produces is 140 lbs. at .625 of lift, the over the nose pressure is right at 350 lbs. and that is very close to coil bind.
Oct 15, 2013nbsp018332spring b would probably provide better performance above 6000 rpm especially with relatively heavy valves because of its higher open pressure of 328. spring a would probably idle a little smoother with higher vacuum, especially if a high pressure oil pump or thicker oil is used. this is a result of spring as higher seat pressure of 125.
Mar 23, 2011nbsp018332now the springs listed below are for a hydraulic flat tappet cam but have a little more pressure than the com cam. so what will i need for my hydraulic roller. this a pretty small cam even for a roller. i have new hydraulic roller lifters just need some
Sep 15, 2014nbsp018332so, you may know the weights of solid flat, solid hydraulic, solid roller and hydraulic roller lifters, steel and titanium retainers. we could compare the effectiveness in weight reduction from changing components. even so, i think the most important effect of roller lifters on spring requirements is the more aggressive cam profiles they allow.
Nov 01, 2010nbsp018332the open pressure is the pressure at the springs specified compressed length, which may or may not equal the actual valve lift on your engine installed height -
Jun 16, 2013nbsp018332theyre really solid flat tappet springs, in my opinion. the 987s are better for a healthy roller, but they still have a lot of mass due to the big diameter dual-coil design. if the 8019s arent collapsing the lifters over the nose of the cam spring pressure too high for the internal hydraulic guts to tolerate, id leave them in.
Valve spring tech. as is widely known, the most important aspect of selecting a valve spring is to get a spring with the correct seat pressure, open pressure, and spring rate for the cam in the engine and with the rev limit that will be used kept in mind.
Hydraulic roller lifters also have needle bearing rollers, but they are not subject to severe impact loads like a mechanical lifter because the valvetrain has preload and there is no clearance to be taken up. hydraulic roller lifters are often criticized for not being able to handle the higher spring pressure required for high rpm operation.

Apr 23, 2019nbsp018332spring pressure needs to be different for various cams and lifters because the different materials require different spring loads so they are able to last. valvespring pressure has a far-reaching effect across the entire valvetrain.
Use only the valve springs that will give the correct spring pressure with the valve both on the seat and at maximum lift. 2. the outside diameter of the recommended valve spring may require that the spring pocket of the head be machined to a bigger size. 3.
Chatter is often caused by insufficient valve spring pressure or by the valve closing too aggressivelydespite, sometimes, the lifter following the cam lobe faithfully. seat pressures used with flat-tappet camshafts are usually in the 120lb to 140lb range.
The open pressure was about 100 lbs less than the edelbrock springs in most cases. unfortunately quotbecause roller camshafts have more aggressive ramps.quot doesnt address the question why edelbrock spring specs are different. im sorry, but i dont consider an increase of up to 40 of open pressure a quotlittle extra pressurequot.
Im trying to get a feel of how radically the valve spring pressures need to increase per amount of additional lift. my follow question to this will be at what point do i worry about longevity of the hydraulic roller lifters might be the limiting factor here and roller rockers.
