Desktop Dyno help
Does anyone have Desktop Dyno and could run a combination through it? I just bought Virtual Engine Dyno and ran my combo on it and came up with 702 hp @ 6250 rpm and I know there is know way it's making that kind of power.
400 SBC 2 bolt with splayed 4 bolt caps 4.155 bore
3.75 eagle forged internal balance crank
Scat Pro Comp 6.0" rods
Keith Black forged flat tops # KB755
Dart Pro 1 230 cc heads. Angle milled to 56cc chamber 13.1 comp mild porting
Comp solid roller .630 lift Dur. 264I 270E @.050 part# 12-908-9
Harland Sharp 1.5 full roller rockers
Vitor E manifold #2978
Holley 850dp
Unilite dist 38 deg total timing on race gas
Hooker super comp full length headers - open
I haven't put the motor in the car yet. I thought it would be 575 to 600 max but if this thing is true I may have to rethink the rest of the drivetrain.

Re: Desktop Dyno help
If you're talking about a 700HP small block you're well beyond what DD can accurately predict. At the 300-500HP level it's resonably accurate, but when you get into the really crazy combos it just doesn't have the intelligence to give you a good estimate. There's only so much you can do with half a meg of simulation code.

Re: Desktop Dyno help
Head flow is:
Intake 308cfm at .700"
Exhaust 207cfm at .700"
I know it's not going to be exact. Just looking for a rough ballpark even just to see if comes up close to what Virtual Dyno said
Thanks
