Link Dead, Please Fixy
Here's an online dyno: Speedwaybids.com
I know, I know, but I've "tested" this using real dyno results from several different builds -- for each one it was very, very close to the actual results (and the differences can easily be marked up to the fact that it doesn't allow "turbo" for boost sources, so is stealing a bit out of its calculation for spinning a cent s/c).
It's also fun to play with camshaft specs and see what happens. You know, like putting in funny car .006 specs with daily driver .050
Unfortunately, this link is dead

Could you give me the necessary specs for an LQ9 (stroke, rod length, volumetric efficiency, and % drivetrain loss for a 99 4x4 rcsb), if you know that info, so I can plug some numbers in and see what it says about my future LQ9? (I know I'm asking a lot...sorry). I have the cam specs and head flow data. Thanks man...I'm curious to try this thing out. I've heard that some of these simulators are more accurate than people give them credit for

It won't actually let you change the VE -- you change it, it changes it back.
LQ9 stroke = 3.620
bore = 4.000
rods = 6.098
I'd go ~21% driveline loss.
If I do 30000psi and 16.5 CR on my truck it says it will do the 1/4 in 42 seconds

Hey, does anybody know the ICL of the Vinci Trucker cam? The LSA is 115, and I'm *assuming* that the cam has 4* of advance ground in, which would make the ICL 111*, but I don't know for sure...
Here's what I came up with
364 cid
10.5:1 compression
303 cfm@551 intake lift
278 advertised duration - 216 duration@.050
.551 valve lift
111 ICL
4700 lbs.
501 HP
396 RWHP
Shift RPM 6163 (I was thinking 6200...pretty darn close)
Max RPM 9038
1/4 mile ET: 13.44
When I hit submit, a window popped up that stated "The heads you have selected may be large for your cam compression numbers". I tried the calculator at 11:1 cr and 12:1 cr and got the same message. Maybe I'll try some different lifts just for kicks.
I was actually concerned about my WCCH stageII 317's outflowing my cam choice, but Richard at WCCH assured me that I'd be fine, and I'll take his word over the online calculator. I noticed on WCCH's website that the StageII 317's flow the best between .550-.575 valve lift, and my cam has .551 lift, so I'm thinking that it's a good match
This calculator is pretty cool...
*EDIT* Lowering the head flow CFM down to 267 made that pop up window go away...
