Introduction
The development target for TOMEI's camshaft PONCAM was "The new performance in all stages". Without giving partial character to the engine or relying on the setting after it is put on, it enables gaining power only by changing camshaft itself. Not like the performance of wide angle-high RPM camshafts that gives special but partial character to the engine, PONCAM gives smooth output character and quick response which is required in today's tuning scene. It provides the performance of tuning camshaft in every kind of driving situation, though, it won't make you feel stressful by falling into the unstable idle.

Valve Timing Adjusted
Valve timing is opening and closing timing of intake and exhaust valve that are linking to the piston movement, and it is expressed with the crankshaft angle from TDC or BDC of the piston. When installing new camshaft, idle stability or low-mid range torque are dramatically charged by 1 degree of valve timing adjustment that controls overlap or valve closing timing. Valve timing is usually adjusted by engine-tuner who is working on with the test driver. So as PONCAM, the best duration timing and the valve lifts are decided from torque characteristic and acceleration data that is based on huge numbers of tests both on the bench actual running. Accordingly, dowel pin is shifted to the proper position at the same time. You'll get the best valve timing without any adjustment but just a replacement of the factory camshaft with PONCAM.

Easy Installation
Not to mention that easy installation of lash adjuster type, also in the solid type of RB26 engine, shim adjustment was almost made unnecessary according to the super-high precision of the size of a cam base circle.

Not Necessary To Replace To A High Performance Valve Spring
In the profile design of a camshaft, Tomei succeeded in reducing the burden to a valve spring sharply by enlarging the acceleration of opening valve, while compressing the acceleration of closing valve. There is no necessity for exchange of a valve spring, if stock spring is in a usable statement at the moment of cam installation.

The Performance In All Stages
The biggest development target of PONCAM was acquiring the high power in all stages. In the past, gaining power at high RPM might be too persisted though; we suggest that the real tuning car should run quickly and smoothly from low RPM to high RPM. In development of PONCAM, Tomei have tested every each models of vehicles both or the bench and actual running for the best results. It is all based on the progress of technology when has not beer realized in the past.

Extra Ordinal Acceleration Performance
Tomei used acceleration G sensors in the test to measure the performance of trial camshafts, and succeeded in giving the best profile that realized quick acceleration response. Installation of PONCAM lets blown engine to have quicker boost response, NA engine to improve combustion efficiency in low RPM, and any car to run much quicker.

Stable Idle
PONCAM is thoroughly designed to give engine stable idle with its suitable duration timing, lift height, and the amount of over lap. Neither an engine stole nor hunching also happens by stability of an idling.

Making A Good Use Of VVT
Variable Valve Timing is the electronic system that controls opening and closing timing of the valve to get a ideal combustion, such as NVCS of NISAN. Consequently, gaining high out put in high RPM and realizing big torque and long mileage per gas in low RPM at the same time. TOME PONCAM is also designed to make a good use of the high performance of the VVT, and enables to give engine the Surely power up from low RPM to high RPM to high RPM combined with the VVT system.

With IN 126 degrees of valve timing, it shows more stable idle and more out put in high RPM. And with 106 degrees, engine performs more torque at low-mid RPM. VVT takes advantages of both of the above and shows most ideal performance.

The Best Performance For "Drift" Driving
As mentioned before, the development target of PONCAM was raising performance in all stages. In "drift" driving, driver controls the vehicle's sliding angle with a delicate accelerator work, and installation of POCAM enables "drift" drivers to control the vehicle much easier with its sharp response to the input. Moreover, according to its better controllability, driver can raise the entering speed at the corner that succeeded in gaining sliding angle distance at the same time.

The Best Fit With Bolt On Turbo
Usually, installation of bolt on turbine without changing camshaft will result in the reducing torque at low RPM since there is not enough combustion occurred at low RPM with stock camshaft. With PONCAM, on the other hand, it will send enough Exhaust gas to rotate turbine ever from low RPM. (And keeps delving power until rev-limit.)

PONCAM + ADJUSTABLE CAM GEAR
Although PONCAM has given suitable valve timing, it is also possible to adjust the valve timing more specifically. Since PONCAM had been set at certain initial valve, adjustment of the valve timing can be done only by shifting cam gear along with the dial to the desirable direction, instead of using lots of measuring instruments and taking lots of times. This user adjustable character would be one of the biggest reasons to install PONCAM.

It is available to adjust the valve timing and change the engine out put characteristics by change the valve closing timing according to the initial value.
- Crank pulley left turn (Advance Valve timing) > Low end boost
- Crank pulley right turn (Delay Valve timing) > High speed gain
