well, kinda.......

i found my copy of desktop dyno 2000. i know its not completely accurate but it'll give you a real good idea of where you are at the flywheel. if anyone wants to know thier numbers just list 'em in a reply and i'll run em for ya.

i need to know the following....

bore
stroke
which heads your using / are they ported / larger valves? (using air flow charts i can get pretty close on the heads)
cam specs (the more detail the better)
intake
compression ratio
exhaust system

should be fun to see what we come up with, and it'll give ya an idea of how many HP that new cam or head swap will give ya and show at what RPM your making the power

heres mine, bare with me while i try to figure out how to post a clickable thumbnail...... ok i have no idea how to do it [&:] anyone wanna tell me how to post thumbnails that you can click and show you the pic fullsize?



i cant add things like a windage tray, roller rockers, multiple spark ignition, port matching, or balancing (all of which i have) - so i substituted my ported performer rpm dual plane intake with a knocked down center web for a single plane unit. should be about right

can you do this for my 4 banger?

my77stang

i believe so, as long as you know the specs i can sure as hell try

r.barn

This should be good.

I know my engine made 465-475hp at 6,000rpm on a "real" engine dyno

Lets see what the computer says.


bore = 4.03
stroke = 3.5
heads = AFR 185's w/ 145 springs
cam = .579/.579lift, 236/248 duration at .50, 112 LS, roller cam
10.2 compression
intake = VicJr.
carb = 750
exhaust = 1 3/4 LT's

i'll have an answer for ya in a few it would help if you know where i can find a flow chart for the AFR's, what valve sizes? \
nevermind i found flow charts

Foxbodyforever

well this isn't whati have now, cuz right now im stock :P but my engine's going to be this

bore = stock
stroke = stock
heads = GT40-P's unported
cam =if you know the specs of the stock cam jsut use those, or if youdon't i can find em probably
9.5 compression
intake = GT40
carb =na
exhaust = 1 5/8 headers, 3 inches headers back, no cats, with flowmasters

thanks man
PS whats the name of this program?

r.barn

2.02 intake , 1.60 exhaust

I think AFR says the 185 flows like 277 at .600 lift

CrazyCobraSpeed

that pretty cool program... ill see if i cant get hte specs for my custom cam... and the specs for hte porting on my heads and get bak with u

my77stang

r.barn, here is yours....



peak HP 502.... so its only approx 5 HP per 100 in this case - which is pretty damn good for a PC software dyno
