i was able to get a couple of pulls today on a dyno-jet dyno.....
2000...100...230
2500...120...240
3000...150...250
3500...180...270
4000...220...280
4500...240...270
5000...245...260
5500...250...240
these are corrected numbers.
the curves are so smooth. the torque curve is nearly dead flat. the hp curve goes upward in such a nice arc.
the sound on the dyno was awesome.
i have some sort of problem, though. the air/fuel ratio was 14.5-1 at 1800rpm, then shot down to less than 10-1 at 2200rpm and was off the charts down there for the entire run. there were some eyebrows raised when the air-fuel was shown on the monitor. i think i should be afraid!
you think that would be taken care of with tuning, or is there another issue that may cause such a rich condition? funny thing is, this is with the STOCK fuel pump! i would've thought the stock fuel pump would've given up by now, but, instead, i'm rich! go figure.
for those who care, here is an exhaustive run-down of the exact mods...
thumper heads (stock valve sizes)
steeda #19 cam
crane 1.7 roller rockers
cobra intake
65mm FMS t-body
stock upper intake tube
75mm Pro-m for 19# injectors, hooked to open air element
underdrive pulleys (not on alternator)
