DeskTop DYNO: How accurate are the numbers? Given decent cylinder head flow data, and realistic cam specs; How close to real world flywheel HP and Torque numbers can one expect from DeskTop Dyno program ?
Are we in the 4 to 5% realm, with good input data?
In modelling some LS motors, I am getting some really HIGH torque numbers,even at modest boost levels.
Example: 4.8 LS, stock truck heads, 212/218 low lift cam, Roots @ 6PSI holding 415 Lb ft at 2000 rpm, rising to 481 Lbft @6000 rpm,
550 HP @6000 and climbing.
.
2nd example, 6.0 with truck heads, 10 psi Turbo, 750 LbFt at 3500,
700 HP @ 6000 rpm, and climbing.
This close, optimistic, or way out left field ?

Numbers seem a bit high, but if it rates them as Gross HP engine dyno numbers, then its probably not far off.
Like I said before, almost every combo has been done. If you want real life HP numbers, just do a search.
