engine specs for dyno2000 program

[Jay eS Iye]

a friend of mine sent me the Dyno2000 program, which is a program that you enter the specs on your engine and you can modify things such as cam profiles, bore, stroke, etc and it will tell you what power changes you can expect. i'm trying it out just to see what its like, but i'm needing some specs. if you can help me out that would be great.

The specs i need are for the d16a6:

bore and stroke (inches)
intake and exhaust valve sizes (inches)
induction flow (cfm) @ something (inHg)
manifold type (single-plane, dual-plane, tunnel-ram, individual runner (I.R.), tuned point injection, sequential-fire injection)
type of lifter (hydrolic flat-tappet, solid flat-tappet, roller solid or hydrolic)
intake and exhaust lift@valve (inches)

there is also this section at the bottom that says:
IVO (BTDC), EVO (BBDC), IVC (ABDC), EVC (ATDC)
when Stock Street/Economy camshaft is selected, the values are:
IVO (BTDC): 12.0, EVO (BBDC): 66.0, IVC (ABDC): 62.0, EVC (ATDC): 10.0
any idea what that is and if its correct?

wow, lots of views but not posts...

well i don't need the bore, stroke, or valve sizes, i searched and found them, but i still need the rest. any help at all???

I use the dyno2000 program, but I use it for my v8 build, not the honda, i doubt this program would help at all with a honda motor. There's not a whole lot of things that can be done with a honda motor short of forced induction, this program is mainly for choosing between the thousands of heads and cams out there for v8s and such. try asking around the forum, chances are anything you wanna do has already been done by someone on this forum

i'm actually just wanting to do it just to do it, my buddy sent me the program so i'm interested to see how well it works

[Autocratic_1st_Gen]

induction flow (cfm) @ something (inHg)
-need a flow bench, flow @ x intake manifold vacuum

manifold type (single-plane, dual-plane, tunnel-ram, individual runner (I.R.), tuned point injection, sequential-fire injection)
-sequential, but for it to be accurate it should need to know what cross section, length, and plenum volume

type of lifter (hydrolic flat-tappet, solid flat-tappet, roller solid or hydrolic)
-solid flat tappet

intake and exhaust lift@valve (inches)
-Advertise Duration: Int=222 / Exh=224
-Duration @ .050: Int=194 / Exh=196
-Lobe Separation: 110
-Gross lift: 333/362

My guess is that the program will be WAY off, it does not ask for some very important variables.

well i've already entered alot of info, that was just what i couldn't find. we'll see once i get everything in tho. as for hte flow bench, what is that? is there a stock number that i could use?

[chopstick1981]

well the flow bench is the machine that measures airflow through cylinder heads... Im guessing that might be a little difficult to find for honda heads. but you might want to try and find some *.dyn files on the net, which are dyno2000 files other people have created, i have ran across a couple of v6 hondas and eclipse files myself. then you could use all the airflow and cam specs from it. I've never tried this program for my honda, but i've tested it against some v8 dynos i've found and it has always come within about 20 hp/tq of the value, so it seems to me to be pretty acurate.

my experience with the program is that you can use it like a G-Tech.. for comparison only. In order to get the stock numbers from a honda (B18A1 = 130hp, B16A = 160hp, etc.) i had to use the "single plane manifold" and run with "hp manifolds & mufflers". It also puts the torque figures very high, but usually the peak numbers @ rpm is usually pretty accurate (the correct peak horsepower rpm)

[Jay eS Iye]

alright, i'll play with the manifolds then. but i still need:
induction flow (cfm @ inHg)
intake lift@valve (inches or mm)
exhaust lift@valve (inches or mm)

and if anyone has them, the IVO, EVO, IVC, and EVC and if they know what the hell than means.

Im guessing IVO=intake valve open, EVO=exhaust valve open, IVC=intake valve closed, and EVC=Exhaust vavle closed, but don't know what they want for the numbers there
