Bean Posted November 14, 2005 Report Share Posted November 14, 2005 Just wanted to start a thread on finding a good software program that might help us build and evaluate our engines. This cam grind talk got me thinking so I figured I'd post some links for you guys to check out. Might be worth to check out... http://www.performancetrends.com/ea-PLUS.htm http://www.virtualengine2000.com/ http://www.engineprosoft.com/ http://www.auto-ware.com/software/es/eswin.htm http://www.proracingsim.com/ Quote Link to comment Share on other sites More sharing options...
Bean Posted November 15, 2005 Author Report Share Posted November 15, 2005 Update - I received replies back from several of them that claimed that they would have no problems with replicating a SOHC Turbo 4 with whatever parameters we specified... After reading V-M's last post - I'm curious if building a "virtual" N9te would be beneficial first to forsee any issues. From what I've seen - these are very accurate simulations if you put the detail into them... Only thing I'd be wary about is how it simulates turbo upgrades - but it should still be valuable to calculate compression ratios, valve clearances, optimum cam specs etc.... Any comments? Anyone? Anyone? Bueller? Quote Link to comment Share on other sites More sharing options...
Trevor Posted November 16, 2005 Report Share Posted November 16, 2005 Sounds pretty cool! What about the jetronic-effect ? does it simulate random power loss due to shorts in the wiring harness? ahah.. sorry i had to. building a virtual N9t does sound like an awesome idea. that would be a lot of fun to play with. I assume we'd have to purchase the software? Quote Link to comment Share on other sites More sharing options...
Bean Posted November 16, 2005 Author Report Share Posted November 16, 2005 I'm definitely curious - and it's so much nicer playing on the computer building an engine than it is in the garage! I'm mostly curious about working out displacement options, proper injector sizing, turbo sizing (hopefully), timing map changes, cam profile changes, piston ,valve clearances etc etc. I'm guessing that if I put the stock engine in as best I can and it comes out with decent results - it should be a nice baseline for building up a theoretical motor - which you can then go directly to build. It would be great to put in the rod specs as well and then toss in piston dimensions as the variable to see how everything is affected. Doing one option by hand isn't a problem - but making multiple changes and seeing how everything is affected would be very cool. Just not sure which one to go with now... (I'm thinking it could be a Christmas present... Rabin Quote Link to comment Share on other sites More sharing options...
Bean Posted November 18, 2005 Author Report Share Posted November 18, 2005 I think I found the sim I want... http://www.proracingsim.com/enginesimfeaturetable.htm The Sport Compact Advanced sim is likely all I need - but check it out for yourselves and let me know what you think... After the exchange it's likely a $200 CDN touch at least so this will definitely be after India trip country for me... Rabin Quote Link to comment Share on other sites More sharing options...
august Posted November 18, 2005 Report Share Posted November 18, 2005 looks good, how about some screeshots! Quote Link to comment Share on other sites More sharing options...
Bean Posted November 19, 2005 Author Report Share Posted November 19, 2005 http://www.proracingsim.com/dynosimSCmainpage.htm I'm thinking that it'd be pretty cool from a theoretical building standpoint... One of the cool things I'm hoping would be to input rod specs, and piston specs into the software so that I could find combinations that would require the least amount of machining with the best displacement increase. (I'm hoping just increasing bore, and if possible offset grind the crank with a longer rod to get a bid of a stroker happenin... OK - I've gotten a little crazy... Hopefully I'd just be able to find stuff that would allow to keep the engine as close to stock dimensions with other OEM parts to replace the stockers... Piston only upgrade would be great - but if you needed to spec out matching rods - or figure out the changes needed to existing rods to make it work - then it'd be super handy to figure it all out. That's what I'm thinkin anyway... Quote Link to comment Share on other sites More sharing options...
Guest Posted December 13, 2005 Report Share Posted December 13, 2005 I've used Mathcad to make some calculations for my car. It's very handy, because you can enter the equations, and just change the parameters and it automatically calculates. I think it would be easy to figure out the bore/stroke problem with it. E: Btw. the formula for the displacement would be as simple as pi * r ^2 * h + Volume of the combustion chamber, so if one is trying to determine whether to increase bore or stroke, he should just try different values for the r & h to see which leads to the biggest displacement... or am I ignoring something? E2: Increasing bore by 1mm leads to more displacement than increasing the stroke by 1mm, so i'd go for the bore. Quote Link to comment Share on other sites More sharing options...
