Boost levels and Tune ???'s
so, now that my car is not breaking up under boost (improper gap on plugs, .40x1, .36x2, .34x2, and .30x1, break up was most likely blow out at higher boost on that .40 plug, and a little on thos .36's), what is the norm for boost upping?
i know on stock SR ECU's, people run between 12-14psi on stock injectors, tune, maf blah blah blah...
SO, since a stock SR is at what, 7psi? and people are jumping to just over ten, would that mean that since my car is tuned at around 13psi, i can run it up conservatively at 16.5psi, give or take .5psi?
i mean, it's only a 3psi jump... at 13psi, my AFR's read around 11.5/6, did a 16psi pull and it read like 12.0-1... i know target AFR's are 11.5/12.0 at full boost WOT, and 14.7 cruising...
now, my car, at 16psi is at 12.1, holds pretty steady, maybe drops to 11.8/9 in the mix... so to me, from all outward appearances, that's safe right? or am i pushing the limits with timing as well?
i know my tuner usually does boost increases in incriments on the dyno, and adjusts per boost level accordingly, so just a 3-4psi jump shouldn't really be all that bad right? considering that a lot of people running SR's, myself included, have ran 5psi+ over stock tuning...
i prob already know the answer, but i'd like the people here who know what the hell they're doing to chime in.... just to confirm or debunk my ideas here...
thanks in advance...
oh, and also, if the car made 416whp @ "14.3PSI" (not proper as that's what's displayed on the Blitz SBCid with the WG function on), and it made 408 @ 14.0psi, would that in effect mean that for every .3psi, i gain/lose 8whp?
