Running a bigger injector won’t want tax the fuel pump as much, plus it will give Brian more room as 36’s are maxed out at 114-115 MPH. Trying to compare a N/A LSx V8 with 10.5:1 compression and two additional cylinders to a forced induction V6 isn’t an apples to apples comparison, as the compression ratios we are talking about at 1.0 bar to 2.0 bar boost on a Buick V6 are in the 18:1 range which is Dodge/Cummins turbo diesel territory. To support those kinds of cylinder pressures and airflow, you’ve got to have fuel, and enough of it. On my 10-second GN I ran a PT-70 turbo and 72 pound injectors using a modified stock ECM and stock MAF, and that car still passed the chassis-dyno smog test, and no, I do not mean the “$250 to a friend” kind (this was the car that I let Brian drive back when he had his learner’s permit.)
