G'day folks, I was wondering what your collective thoughts are on at what boost levels should one use low compression pistons

sorry bro, still learning to navigate here. I just posted in the build.TractorTruck,
Pleas start a build thread. The more info everyone can see helps everyone learn. Even the Einstiens can enjoy reading what they already knew, because they learned it at some point also-reminiscing is great!
long story short a better turbo would do great for that motor. IMO a T3/T40B Turbo is just what the doctor ordered. This is the about the same as the turbo on the Dmax now and is a bolt on. No need to modify and is rated at 400hp at 10 psi and you only need 8 psi of it. It comes with the option of a built in waste gate set to order. Now forgive the long way around, a lower compression ratio is a good thing for high boost on this motor if your doing high power mods and what not. It is not really needed to get good power out of a stock motor. Despite what might be said, really a better turbo is a first stop. I don't recommend treating your engine the way I do mine as I can build mine anytime, and it is what I do for a living. Now, at 16.5:1 you can go as high as 45 psi for short hard romp. 30psi is good and safe for a hard long romp, and 15psi nonstop. 18;1 25psi short romp, 20 psi long romp, 10-12psi nonstop, after that you are back to stock pressures. When I find it there is a good read on how all this works with all the math and everything, I just don't remember where. Hell, I have to dig through my file cabinet and other stuff to find it cause I did print it.G'day folks, I was wondering what your collective thoughts are on at what boost levels should one use low compression pistons
