Bore x Stroke. Share. Even after the piston reaches BDC (bottom dead center) and starts back up on the compression stroke the intake valve is still open, allowing more air/fuel to enter. Performance will improve with improved induction, i.e., carburetion or a more efficient injection (ported/polished throttle body) and exhaust system (headers). Nevertheless one should always check valve spring squareness, free height and installation height spring force. As the piston goes over TDC and starts downward, the velocity of the air/fuel mixture increases as the intake valve reaches maximum lift. 13502-AE871. *These figures are not actual power ratings but ones posted in catalogs at the time of sale. This will establish the base line from which tests can be made and the cams advanced, retarded, separation increased or decreased as desired. of the lifter (bucket).

Sharing time with others who are ca. The heat from the header can cause these to fail over the course of time. Head with slightly different porting configuration. The exhaust valve is left slightly open as the piston is once again brought up to top dead center. Using quality parts is the key to an engine which not only makes big power but is reliable. Today we still host for a fourth generation of fans, and have proudly kept intact for over 25 years. Now this depends on the weight of the vehicle, momentum changes (acceleration and deceleration), gear ratios, track conditions, etc. Note, when adjusting the cam sprocket, make sure the ignition timing is corrected between each cam adjustment. Ground on new billet cams. The placement of both events has a significant effect on power, i.e., exhaust valve opening determines the beginning of the exhaust cycle and cylinder blow down, and the placement of the intake closing event fixes the balance between cylinder filling and intake reversion. Used as an exhaust cam with 304° intake in TRD rally car (max lift @ 98°BTDC). 4AGE 20v Piston Rings. With that said, it is also recommend that you follow all the recommendations the manufacturer of the cams has to offer. My conclusion is that there's as many bad tuners out there as there are rattly old 20V's at the importers. Some cams work with the VVT and others can either utilise the VVT or you can use adjustable gears if you wish to set fixed timing. One of the many tricks that early hot rodders used to do (and still do) was to grind camshafts to the lift and duration desired. (courtesy of Toyota Corolla Himeji Dealer Japan.). The lobe center is usually between the opening and closing angle, but not necessarily so, especially if the opening and closing ramps are not symmetrical to each other. -- Moto Miwa - Webmaster/ Founder, CLub4AG. The intake charge can be visualized as being “parked” in the port waiting for the valve to open.
