Okay speedy, I'll do this the right way. Clear cut case, here you go. When I dynoed before I had gotten the nitrous, I was pushing 1bar of boost at dangerous lean levels. This was not because of the fuel pump however, because matt was using a stock pump with larger injectors for quite some time. This means that the injectors simply cannot give me any more fuel. Now that I have the nitrous in, 100hp worth of fuel is being used for that, which I can imagine will start stressing the pump out. I am putting in a walbro 255lph to give the nitrous and the injectors the abillity to use the same amount of fuel as before, but this time with no danger of burning out the pump. I will not be able to increase the boost, since 1 bar was too lean on the dyno, it would still be too lean to boost that now. Now do you understand? Any more questions or qualms?
