Stock computer as well!Some folks think you're fibbing, but I don't. Apologies not necessary, especially when I specifically asked for your results. Anyone who's upset has their own problems, although I can definitely understand the BS flag. A simple explanation: the Dyno was wrong. Corrected values when the atmospheric conditions aren't properly implemented can be WAY off, as they would have to be here. Also, a dubious dyno operator can really skew results badly if he's trying to impress.
Someone else in here stated the stock 88 LPH pump is done at 230 rwhp. The math backs that experience up, too: on an N/A motor, an 88LPH calculates to 280hp, ~238 rwhp. More fuel pressure helps injectors but hurts fuel pumps. There's no band-aid for that. If you're right about your stock pump, then the dyno is reading about 50 rwhp high. Your combo would max that pump out and we'd see it leaning out up top, but the AFR curve is nice, flat, and rich the whole way.
A full Performer headed combo is good for 290-300 rwhp. I'd guess a stock cam and 55mm throttle body would cost about 25 rwhp. So, a 265-275 rwhp guesstimate, even with the ability to feed it the fuel. That still feels optimistic, though.
I don't know man. Another thing that strikes me as odd is how perfectly flat and conservative that AFR is. How was it tuned? Is it just the stock computer? I assume you didn't play with fuel pressure since you didn't even know its setting earlier. That's just another odd thing to see. Just one more part of the equation that doesn't work out.
Sure would be nice if you could take it out to the track, or pair it up with someone that has a known combo. You don't travel out near me in Cali, do ya?
