    About Cylinder Pressure

    Brian I said "never ignite the engine less than 8 degrees BTDC" means (ingition <8 ) I generally tune up more than x>8

    Java - IDE NetBeans - Upgrading excel-like spreadhseet to the windows-like desktop application

    You should you com+ objects to access the office libraries and directly use background side of the office products. You can access everything with DCOM++ to excel worksheets.

    About Cylinder Pressure

    ATDC between 12* and 16* degrees but this can change by engines. But the most mechanical stress occurs when the fuel ignited not after it burned. never ignite the engine less than 8 degrees BTDC, after that it starts to erodes the conrod bearings

    VVT tuning

    you are retarding your intake cam too much and sudden. you should increase your exhaust timing a bit at higher rpm range. I am sure you can achieve more power higher rpms! you have advance your intake camshaft timing over oem parameters, and retarded the exhaust timings to achieve the similar...

    high hp/cylinder engines...

    it's related with the materials, the atmosphere and the usage, You can not have any prediction about this question I though. You can pass: 1000 passes without any trouble with reduced cylinder charge, reduced and cooled cylinder pressure, good lubricants, good mechanical stress and etc. 10...

    Radiator Cooler Design

    I checked that radiators should be designed for engines needs. not for cooling the water for more efficient way.

    Effects of Air Temperature on Turbo Diesel WHY lower than Turbo Gasoline Engines?

    Generally, the newest model engines equipped with direct injection systems are better on performance output and better on loss of power related with Air temperature. I tested lots of engines with multiport, single port and direct injection systems and can easy say that, DI all the way better for...

    Effects of Air Temperature on Turbo Diesel WHY lower than Turbo Gasoline Engines?

    So can we generally say like this. Turbo diesel and GDI Turbo Gasoline does not get much effected on power output from Normal Port injection Turbo Gasoline engines! Is that right?

    Effects of Air Temperature on Turbo Diesel WHY lower than Turbo Gasoline Engines?

    How can we explain the charge air temp does not effect the power on Turbo Diesel Engines not more than Turbo Gasoline engines and WHY?
