what would happen if i ran 72lb. MSD injectors with a stock ecu and safc?

im just curiouse if it would even run. i have the stuff waiting to go on, i just need a tuned ecu or some form of tuning.

would i be like shooting 10 foot flames or what?

should be ok dude.. seriously, get a fuel pressure regulator, and a fuel pump, and play with the safc!! =D

With an sc61 turbo I would be worried about timing as well. Which MAF are you running? Get an ecu ASAP before you even run it.

would a safc even manage 72lb injectors? I thought you could only go a maximum of 50% over stock with stock ecu and safc?..

im running stock ecu, z32 maf, safc, stock injectors rail and regulator, walbro 255.

running now at 10psi. im probobly destroying the engine. been running like this for a while now though.

SAFC can't go that high on injectors, like mentioned the correction factor is a maximum 50%.

If you ran those injectors without any kind of boost, on a stock KA , you'd be running super fucking rich. It'll probably run but you'll get shitty gas milage. The s-AFC can only adjust so much, and you'd want to tune it carefully as not to go to lean. Just wait and do it right with tuning and setup. And yes a FPR is a good idea , with a gauge.
