Like the topic title says anyone ever use any kind of engine building software or anything like that?

 

hm.. interesting.

bumb for an interesting question

 

yep, ive used desktop dynos and it is pretty acurate w/ my set-up.

 

i bought the desktop dyno book at barnes and nobles for about 30 bucks about 2 weeks ago. it's a previous version that runs on dos. there's a new version out and it's more expensive. i don't know if cartech or motion software have a website but if they do, you can probably get information off their site.

any how, the desktop dyno is a good way to learn the basics.

 

Im thinking of getting this softaware from Reher Morrison. It will calculate all kinds of stuff for you. I may also get the engine building books from them also. They may not be building the fast Imports but they sure can build a fast NHRA Pro Stock engine.

 

back up for curiosity on the newest products.

I use Engine Analyzer Pro. v 3.3

and I love it. It has a preloaded engine library and it actually has both low and high cam dynos for a 00 integra type r engine. All the specs are dead on and you can actually control, graph and view so many differnent aspects of the motor its mind boggling.



A friend of mine has used this program to design a 615ci (10.2L) pullin' truck engine and everything was so close he made within 45hp of what the program said it would. Not bad when its a 8500rpm big block breathing through a single 4bbl carb.

It was within 5% and once he went through and changed the variables for the different headers on the dyno and the fact that it went through mufflers and also that the temp conditions were slightly different it was damn close.

It's very helpful when designing an engine. If you have the air flow #s of the head/ intake/ exhaust you will be able to dial in the precise camshaft for producing the kind of power you want. The program will also let you know if you are going to be having valve-valve/piston or piston to head clearance issues as well.

only are the cost of the program and that its not for noobs.

oh yea I almost forgot to say that it has many turbo and supercharger designs in its library as well. It is about 2-3 years old now but Nascar engine builders still use the program.

Yeap, I use a version of engine analyzer also. It can be pretty accurate if you have parts available for measuring dimensions.

 

so you guys use the import version?

what about the highest-end one that costs 600$ or so. it has a few features that no other version has, but is it catered to 4cyl. engines as well?

They claim that if you have every variable correctly adjusted in the program then the margin of error is less than 1%.

The version I am using is several years old but it was over $500 when it was new. I read in a Competition Cams publication that they have come out with a completely new program that is supposed to knock everyone's dicks off. At least as far as modeling and simulations go.
