Engine dyno software. Anything good on the Internet?
bet you don't get the updates .They added quite a few new parts to the program list of parts
3.9 is the latest version and it was free so I'm not complaining. To my knowledge the only updates they have done are to include more preset parts to choose from, for example when choosing cylinder head specs, instead of putting in all of my own dimensions that i've measured from an actual part. I may be able to select that part from a list.
ie. selecting "hemi 6.4 apache cylinder head" will bring up it's corresponding port volume, length, cross sectional area, valve size, combustion chamber shape and overall flow numbers.
However most of these files included in their updates are estimates anyhow and not intended to be 100% accurate, if you want to make the most of this program, you need accurate data that is based on the very cylinder head you plan to use. The same goes for other parts.
On the occasion that I have a serious go at trying to calculate a combination's output it seems to be highly accurate. but it's a lot of work to obtain accurate date to enter into it.
Hence why I say "I muck around" with this program, because it is beyond the scope if my needs. I just like to make comparative calculations to see what effect it would hypothetically have on "changing x component on an engine".
It's pretty intensely detailed, if you want to get serious you can even weigh your valve train components and it will give you an indication as to if/when valve bounce will occur.
It can also give you base jetting estimates for holley 4bbl carburetors, but clearly states that they are an estimate and should not be relied upon in absense of a dyno.
You can compare ignition advance curves or any shape, or lock the curve out completely.
If i was responsible for building serious competitive motors I would gladly pay the price to buy a legitimate copy of this product.
