Grinding down the base circle of a cam is a traditional tuning technique, it increases valve lift and gives longer opening. The key is to make a smooth transition from the new base circle to the lift segment and have a progressive lift. People complaining about loss of cam hardness forget that the base circle is not under load, so not subject to wear. Note the very large oil feed holes in the base of the cam - it's not likely that this cam is starved of oil.

The naysayers on here need to rethink...this guy is the real hotrodder, not someone who can only order from the "comp" catalog and barely know what the specs mean. I bet Ed iskenderian, vic edelbrock, and David vizard tried this sort of thing. The lift is easily measured, and the LCA/LSA didn't really change. Opening/closing and duration could be easily measured, too. He only altered the base circle and opening/closing ramps, so spring pressure is low when rockers are even in contact with the lobe. Flat tappet cam lobes are often slightly conical, to promote lifter rotation, so we know some misalignment is tolerable, his eyeball work in this area doesn't look too bad. This is probably from a little OHC motorcycle, the lobes are giant for the little valves and light spring pressures they have to deal with, I bet they'll have a reasonable life if no valve-piston contact occurs. This clever guy probably owns 5 cheap little motorcycles for the price of the cheapest billet part on your street rod that was built by someone else, with money and a catalog, rather than clever craftsmanship. Again..this guy is the real hotrodder. You should be embarrassed. (I do feel sorry for the leadscrew and ways on that lathe, I'd have covered them!)

Grinding down the base circle to increase valve lift and maybe duration is how performance cams have been made from standard camd for a very long time. Much cheaper than starting from a new blank, but limits the cam profiles that can be used, and smaller base circle can cause issues with hydraulic lifters.
@lelandlewis72072 жыл бұрын
@@ferrumignis It can cause issues with any flat tappet lifter in a few ways. If the diameter of the lifter is too small for the profile, the edge can catch the lobe and destroy everything. Mushroom lifters or larger diameter lifters can cure that. On a solid lifter, you need an opening ramp that takes up the lash clearance or the shock can chip and destroy the cam and lifter and a closing ramp to soften valve landing on the seat. Hydraulics also have ramps, but not as pronounced since there is no lash. By cutting the base circle flat, as is done here, the lifter would no longer spin, causing premature wear and failure of either type of flat lifter. A cam that is reground also requires a surface treatment, usually parkerizing.

@@robertking1032 I was pointing out that a grind not only affects hydraulic lifters, but is more critical for solid lifters. The advantage of increasing lift to probability of cam failure would make this method very debatable. Cams are the most amazing part of an engine due to the abuse they take with hundreds of pounds of spring pressure on the lobe at lift happening hundreds of times per minute, but, they are also one of the easiest parts to destroy. A professionally reground cam is as good as a new cam, but i think done this way, a flat tappet cam would have a very limited life.
@stevenbelue54962 жыл бұрын
@@lelandlewis7207 you hit on the things I had in my mind. I could see this working on a roller setup maybe but not a flat tappet. The wear pattern on a flat tappet would be hard to get right, might could get the circumference smooth enough but the profile across the width of the lobe that aids in lifter rotation would be hard to get right, the taper on the lobe has to mate up with the convex shape on the lifter seat just right in order to spin the lifter and in most applications keep the camshaft seated in one direction of another against a thrust. In the well known sbc the tapered lobe keeps the cam seated to the rear of the engine and the timing gear has a thrust to keep it centered and off the pressed in plug at the rear of the cam tunnel. If one didn't get this profile right it would ride up towards the front of the engine causing timing chain issues, distributor gear issues, and issues keeping the lifter centered on it's lobe. There is more to it than many would think as Mr Lewis has pointed out. A roller cam would negate some of these issues but it's just mite near impossible to do it manually or free hand.

Даже если это не его станок то это не повод насрать на него сверху.

Eine Methode, die vielleicht in den 50ern Jahren des letzten Jahrhunderts funktioniert hat. Ich habe selber Nockenprofile berechnet und Nockenwellen Für Rennmotoren gefertigt. Wenn schon keine neue Profilberechnung, dann aber die Erhebungskurve über den Faktor berechnet, der ruckfrei über das ganze Profil funktioniert. Dazu wird das Profil der alten Nockenwelle in 5° Schritten übernommen, mit dem korrekten Nockenfolger, und dann mit dem Huberhöhungsfaktor multipliziert. Anschließend auf einen Meisternocken übertragen und auf eine Profilschleifmaschine geschliffen. Anschließend gasnitriert um eine Mindesthärte 58 - 60 HRC zu erhalten. Alles andere ist Schmiedetuning!

I wonder what the spintron has to say about this?
@hiperformance712 жыл бұрын
The Spintron is a machine used in motorsport to study the valvetrain of a racing engine, it spins the crankshaft and all the internal parts moves like the motor is firing regilarly, but there are not cilinder firing, just spinning. They can film the movement of the valvetrain at the max. Revs permitted by the engine in study, they can collect measured data of various kinds. Probably, the spintron will ask, "what engine are we testing today, 1904 ford model T?"😂

@@didhasalim2686 dengan pemangkasan tinggi klep justru posisi bukaannya jadi lebih rendah.

@rafaellastracom64112 жыл бұрын
By grinding material off the opposite side of the land you can bring the valve closer to the camshaft using shim kits. This way you add lift to the camshaft profile.
