i know that...i meant how much boost with the 310s until they max out....i know the calculation is with horsepower, so with 9.6 compression, i will have more horsepower....would i be safe with 10-12psi with those injectors? after that im putting in 450's, water injection, and upping the boost}( ....i heard someone say with 8.8 they were maxing the 310s out at 15....so i figure 12 might be the same as that...im just going to do whatever the 1g wastegate actuator opens up at...i thought it was anywhere from 7-11psi....
