If lash is accounted for when converting lobe lift to valve lift on a solid tappet cam, is plunger depression on a hydraulic lifter accounted for? E.G., I have 7/16"-24 rocker arm studs on my SBC. I preload the lifters 0.025" (1/2 turn). When the engine is operating the internal piston of the hydraulic lifter is compressed until a check valve is employed to close the oil inlet orifice. Since fluid is not compressible the lifter then behaves like a solid tappet, until the pressure is relieved on the closing flank, back to the base circle. Is that moment of compression accounted for in the formula?
I've tried to contact you via e-mail several times and gotten no reply, with questions about engine parameter options for the Classic Mini/Midget 1275cc. *siamese intake/exhaust ports, twin SU carbs, etc.
So when comparing hydraulic flat tappet to hydraulic roller cams with the same lift/duration specs is it better to not use the 10 point modeling as the roller has more high lift duration (0.200"+ lift range) and hence more area under the curve that 10 point modeling won't see ? To more accurately model a roller lobe would you not need 7 instead of 5 profiling points ? I bring this point up because i find that when modeling and comparing similarly spec'd flat tappets and rollers the rollers don't make any more power and that just seems counter intuitive to me , Please Explain how best to compare flat tappets and rollers . thank you
I observed that when the Summit cam card data was entered, the lift at .006 was clearly stated on the card to be at tappet lift, however it a was entered as valve lift in the simulator input... Also does this mean that Summit is not using SAE standard or am I confused about the standard? Am I missing something here? Thanks, great video!
Dynamic compression would be an extremely valuable thing to determine with this program as well as cranking compression psi . Actually there are many things to be learned with this information in hand .
This really expanded the possibilities for me using Dynomation .......Thanks Larry !!!
How do we get this? I have a old 2000 I like to use on my old windows 98 . Still works! This is the only thing that I have it for. I have a Mac now. Is there any way could get a new one for it? You have a lot of new stuff in this compared to my old 2000.
You can find more about the software at www.motionsoftware.com. Our latest version six simulations require Windows 7 or later. Thank you very much for watching the video and for using our old Dyno2000!
Good stuff Larry. Really enjoying these videos. Many thanks for making them. Regards Greg
Thanks Greg! I really appreciate your comments.
You guys need to make a version compatible with MAC OS for apple users
I honestly thing DynoSim6 is worth it even for hobbyist like me. I am located in EU and engine builders with knowledge about American V8s other then windsors are very hard to come by. Ability to compare cams and figure out if you did not go too far for street use or if you are limited by carb, valves ... quite amazing.
Thank you very much for sharing this information. Really a very good video. I'm seriously thinking to invest in yours simulation program. I'm Italian , can you see problem to ship here in Italy, and have assistance and consult with you?
Thank you very much. I’m glad you enjoyed it. If you purchase our software, we can ship to Italy without any issues. And I’m always available at support@motionsoftware.com. Thanks again!
I can verify that Larry is always very quick to respond to any questions or problems I've ever had ! ..... Rick Miller
Very good video. I used to build a lot of Cleveland's, and I always got my best results with custom ground cams. Without realising it, I was selecting more suitable LSA's than was being specified by the cam manufacturers. Canted valve heads respond differently to inline valve heads, as far as overlap goes. It wasn't until I read DV's books that I understood why I was getting the result. Thoroughly enjoying your series. Looking forward to your next instalment.
Thank you very much for watching the video and for your comments. I really appreciate the feedback.
@motionsoftwaresim i was looking at your product range and see that you ship your products on cd. I don't own anything with a cd drive any more. What alternatives can you offer?
Hi, all our software is available either on CD or as a download. Just click one of the blue buttons on our purchase page on our website and it will take you to our online store, where you can select CDs or downloads. Thank you.
Great video, Larry! In 2023, I am puzzled why cam card info. is STILL not identified properly - can be confusing!
Interesting video. I would buy DynoSim6 as soon as possible
Crazy question: I’m thinking of getting your program to help me with my Harley build: with the exhaust/header part how do I make sure that it’s simulating the proper 45* with a shared con rod.
Thanks for your question. The cylinder centerline included angle is not directly modeled in the engine simulation. Changes to block design have little effect on the thermodynamic properties that are modeled by our simulations. So, our simulation will model your engine with good accuracy.
@@motionsoftwaresim I’m not as much worried about the thermal properties and the timing of the exhaust pulses/pressure waves. Mainly for scavenging and collector design.
The timing of exhaust pulses and pressure waves is established by the valve timing, not crank/rod relationships.
Ive been following you since the overview. love what you push out there. buying denotation6 soon. cannot wait to learn this.
Thank you! I appreciate your comments.
Thoroughly enjoying this series. Does your software include the ability to model flat plane vs 90 degree crankshafts? Or other odd angle cylinder bank vs crank phase situations?
Yes, both DynoSim6 and Dynomation6 will model any crank design. However, there are no options to select different cranks; the simulation model primarily performs a thermodynamic and frictional analysis, so is not very sensitive to crank phasing differences.

I still have a lot of your programs, but unfortunately I don’t have anything with windows anymore and you guys were mainly based on windows platform, hopefully in the future I can put this stuff on my iPad! I usedused it a lot and it’s really good information to have for designing and building engines
Windows 10 laptops can be found used for $100-200 online auction or pawn shops. Cheap machine compared to $150-$600 powerful software.
Can someone point me to free simulation software 🤔
None that will do what this will do. (Accurately predict minute changes to 1% of outcome in reality). This is the ledge between <$1000 software a professional shop can use, to $25,000+ engine design CFD software the big-3 utilize to develop new modern engines.
I suggest HPwizards Horsepower Estimation tool (online) it is simple but effective for basic estimates. As long as you know Stoichiometry, Lambda, horsepower, and fuel flow rates you can find Volumetric Efficiency. Once that is found, you can hold VE constant, and manipulate other parameters. Or change VE by an estimate of what you expect an upgrade to make (e.g. +3% or 0.03 VE for long tube headers, +0.01 for high flow air filter. Also can play around with Boost, etc.
In the early 2000s, I bought Desktop Dyno 2000, then bought Dyno2003, Drag2003 & FastLap2003. I later got the matching Sim upgrades and trialed DynoSim5. I messed with FL the most, but found the track design implementation very frustrating.
Thanks for the comments regarding our early software development. Sorry you had issue making custom tracks for Fastlap. I wrote the track-building explanation in the FastLap Sim5 user manual, and I thought came out pretty well, but That was quite a while ago, and it may need some improvement. Thank you for being a customer.
MORE!!!!!
Thank you for the encouragement! The next video is a few days away.
Never saw a spinning valve spring. Lol. Bv
Yes, a lot goes on in high speed dynamics. Also, the valves rotate which helps keep the seats clean. Thanks so much for watching!
$499.95 U.S on special, $650 + shipping Canadian funds. No Thanks
Wow, that is a lot! Exchange rates! Send an email to support@motionsoftware.com and I may be able to provide some suggestions. Thanks for watching the video!
Chassis Dyno time is $500/day everywhere in the free world. The best tuners for MoTeC and ProEFI charge $1,000 per day. Plus actual cost of airline ticket and hotel. New turbos are $3,000. If it's the wrong size, you will be lucky to get $2,000 for a used non-returnable item. -$1,000 mistake, plus weeks of time to instal and attempt to tune. Now you gotta hire a pro tuner and Dyno AGAIN to make the new turbo work. With software, the mistakes will be small. Like 0.5" too short of runner length. Or 1% fuel flow difference than expected. Or 5hp less than you thought it would, on a 550hp build. $600 is a bargain, when you can use it to get everything right the first time. I see people spending $600 on aftermarket tuners that are flashed with half a dozen canned tunes that aren't even optimized for their own specific car and mods. Like, wtf?
Had desktop dyno for years until my computer blew up. Just bought the bundle package, dyno/drag/roadcourse and have been wearing out this computer!😂😂
I have been trying to replicate modeling results using 10 point data and comp lobe profile data. (TK lobe profile solid rollers) I assumed that the lobe profile data would provide a more accurate simulation, but in most cases, the hp and torque differ more than 10-15hp/ft-lb between doing the sim with 10 point cam data and the same imported lobe profiles. Should the results be the same? Which is more accurate? Where can I get help online without having to wait on hold for a long time?
In general lobe profile simulation should be more accurate. But there are quite a number of factors that come into play. Send me an email at support@motionsoftware.com and attach the engine file you’re working on and any other cam data that would be helpful. I’ll be happy to look at your set up and see if I can offer any suggestions.
OMG...blast from the PAST, I had the book and DT Dyno (Windows 95).
A video idea. Go through all of your available software package and give us a buyer's guide if you will. Thanks
That is a good idea. However, I wanted to keep the RUclips videos as “commercial” free as possible. However, over time, I’ll discuss most of the features of the software. Thanks again.
Back in the 90's I bought your book, Desktop Dynos, which I found to be very interesting and informative. Also had software back then that I think might have been from Motion Software. It was on a 3 1/2" diskette!! Just this morning this video showed up in my suggested videos. Glad that it did and will be looking forward to more videos in the future.
Thanks so much for your continued interest in our software. I really appreciate it!
So glad your doing video’s Larry
Great video
🇦🇬 After watching video 1 as per your suggestion, am now back. ⭐️⭐️⭐️⭐️⭐️ 🙇🏾♂️
I thought y’all went away. I haven’t been able to update my simulator for several years. I always get “unable to connect to server”.
Hi, thank you for leaving a comment. Please contact me at support@motionsoftware.com and we’ll try to figure out why you can’t download updates. Thanks again.
@motionsoftwaresim, we Need many other video like this. Many thanks for sharing your knowledge
Larry, you were correct. I did garner a lot of information and understanding just in the viewing. So the software can simulate the performance results from varied cam specifications. Can it also recommend the optimal cam specifications or is this obtained through running multiple simulations with incremental changes? Thank you
Thank you for watching the video! The software also has a feature that will run multiple simulations while varying cam timing to find an optimum result. We call this the Iterator. It will be discussed in an upcoming video. Thanks again.
@@motionsoftwaresim you left out/forgotten the dodge 5th-gen vipers v10 cam-in-cam so yes LCA ( and VVT ) cam be changed ( and technically you could use the cam design/core for a 1:5 to 2:0 rocker's ratio or down to 1:1 / less than 1 not sure why'd you do it though ) on the fly as i own a 4-th gen cam core but phasers and or manufacturing limits the maximum range the computer or you could command it's about 10* to 20* LCA ,90* probably could have been made but it's not all that useful i got to copy/learning it for my V8 dodge did you remember the multi-air system from dodge? as some people are tuning for more power ect
outstanding i've been looking for a video on this subject
Thanks for the feedback, I appreciate it!
