I have 16g evo 3 turbo, that is considered a big 16g,15psi,3 inch turbo back, noo cat, k&n filter,new side mt intercooler STOCK,3 inch intercooler piping,gm maft with translator, SAFC2,450cc injectors with a 255 walli,forge bov, stock mani and internals, no tune "meaning dyno tune" i have 2 maps, one at 15 one at 23psi, at 15psi im sure i make atleast 300whp bro..
You will not hit 300 with those injectors. The rest is good. You do need some injectors to get 300. I would get some 880cc injectors. The fuel pump is the only thing that will get you what you have. You will have very good tq numbers but, your hp, which is a function of tq, will fall off around 6000 or so and, you will be short of 300 by a fair amount. If you get some injectors, you can reach 300 or so with a decent tune and the boost your are running for high boost.
The guys on here are right that you are not running 300hp. You may be running close to 300 or so lbs of torque but not hp. You are on your way with this car, you just need a few more things though. Take it to a dyno and see what is going on and go from there. That is the best advice I can give you.
