I have been obsessing over camshafts lately, lol.  I have been studying them thoroughly and reading all the debates.  I have been playing with the Cam Quest feature provided on the Comp Cams site, but it only uses their own cams.  Is there a software I can buy or download where I can enter every number of an engine right down to the last detail, including camshaft data.

I want to "build" different engines and try different cams in them.  Unfortunately, I cannot afford to do that in reality, too expensive, LOL.  I would love to play with it and try different things.  I want to enter actual camshaft data as well as made up cam data just to experiment and learn.  What do you guys use?  How can I get it?  Laugh

If some software included vehicle aspects, like weight, converter stall, trans gear ratios,  rear gears, tire height, etc...  That would be cool, too!

Thanks, 71.  I remember picking through that site in my searching.

Which package do you use, and would you recommend that?  It looks like some of the upper $$ packages include aftermarket parts you can enter into the simulation and there is maybe a little more intimacy.  I would imagine that this software is more geared towards Chevy products.  That said, I am thinking maybe unless you're building SBC's every single day, maybe the 40$ package is suitable?

I use the same program that My71 has, I think I paid about $100 for the version I have. If you have Jim Hands book the flow rate for D-port heads comes in handy because you can enter specific head data to get the most accurate simulation possible.

69,
Like Steve, I bought the full on package. It has several different manufacturers and you can also enter specific data and customize each section.

if you want to dream drag racing, there is the 1/4 mile sim, by patrick hale, called 1/4 jr. it estimates 1/4 mile times and speeds based upon car weight, traction, gearing, power etc. his desk top dyno, as it was called ,was the first virtual dyno, way back in the 80's.

I have used Dyno 2000 for years and really like it.
Here is a free one, in case you missed my first link.

Thanks guys.  I ended up getting the "standard version" for $35 or 40.  It was okay.  I wasn't all the impressed.  It looked like it was designed in 1998 or so.  Maybe the 100 dollar version is much better.  I will consider upgrading.

I only got to spend an hour or so with it. I only had it for a week or so, then my computer crashed! I got a new comp, but trying to get them to allow me to redownload it on my new machine.  Still waiting to hear back from them on that...

Curious - those of you who are experienced engine builders, have you found the Virtual Engine simulator predictions accurate compared to actual results at the dyno or the track?

Really?  No-one uses this program to design an engine, then build it and test it?  I hope to build another engine or two in the next 4, 5 years, so I really am curious how the pros do it.

pro builders use sims bro, they even have data banks, or at least some do.

Bro, what I really wanted to know was do the experienced engine builders who said they like this program rely on it to plan their engines, or do they use something fancier.  I see the pro packages online, probably more than a hobby builder (like me) should spend.  I did buy the $89 package of VirtualEngine 2000 and played with it for a couple hours, it's a lot of fun.  I thought I'd input a couple engine builds from published articles that did get to the dyno and see how the program holds up against those results.  Since I'm also doing an autopsy on my own motor in the next couple weeks, I'll try that, too, and see what comes of it.  All part of the learning experience...

there used to be a guy posting at these forums [went by the handle budnicks] and he said... fill your library BEFORE you fill YOUR garage... a WISE MAN !!

For those of you who use the $89 version of the VirtualEngine2000 (or better):

I've modeled a couple motors that were built and dyno-ed in various articles, and so far they come out pretty close to the published results.  Close enough to think this is a good tool to use for comparisons of cams, compression, head mods, etc.  But, once I have a model built, it doesn't seem to accept changes to piston compression height, deck height, block or head changes when you make them in the library.  Anyone else run into this?  In order to change compression ratio, the only thing I can get to work is changing the combustion chamber volume or gasket thickness.

Thanks for any feedback.
