Anyone monitoring this thread that has experience with modeling software? I used the early version of Desktop Dyno for several years with the small block Chevy and it worked fine. I wasn't as much interested in pinpointing a torque or horsepower number as I was seeing a general torque curve for various cams/heads in street engines. I'm a believer of a long flat torque curve for the street

Then I tried it for my first LS1 engine and it just didn't work. The software couldn't handle the LS design as it had not been programmed to do so. It generated far off numbers. So, my question is do you have experience with more modern software packages than can accurately model the LS engine? What are your experiences and what package did you use and what are your suggestions? The latest version of the old original Desktop Dyno that I was using is version #5 and although it's been updated I'm not sure if it handles the LS properly.

I don't want to spend a huge amount for a onesie or twosey use of package so I am looking for reasonably priced and accurate for the LS.

Before someone jumps in and tells me that modeling software is trash I can tell you from experience that it works, is reasonably accurate and is especially helpful in modeling various combos like heads/cam and for choosing the best (based on desired usage) cam for a given combo. It's a better predictor than a wild a** guess or what Homer down the road or on the net put in his car. OK, now that discussion/debate is avoided.

I realize a lot of people are going to the cam designers for cam selection which is great but I enjoy "rolling my own combo" to convince me I'm going in the right direction. Of course, once I feel like I have a good combo nailed I would next talk to a good tuner for input.

So, anyone with any info on modeling software please speak up.

Thanks

Rather than experiment or roll your own... you could give Tony Mamo a call, he's been there done that...

Don't understand your comment. I'm looking for modeling software to predict HP/Torque outcomes of various engine combinations. Works like the old Desk Top Dyno software but for LS engines. Has nothing to do with tuners or tuning software.

Not to take anything away from professionals such as Tony, but I enjoy doing my own thing - that's how hot rodding moves forward. How do you think Tony got the experience he has? I'd guess "rolling his own and testing".

 

Occasionally... Ok, fairly often... Honestly, it's most of the time... rather than letting someone think I'm as idiot... I just do something to remove any doubt...
Your obviously in deeper water than I am prepared or knowledgeable enough to venture into... good luck with your project sounds like your going to have some fun

 

No problem. I've been a computer programmer and really enjoy working with the simulation software. Amazingly accurate (most of the time). Been to Chevys for years and enjoy being hands on (brains on?) in creating good engine packages.

Thanks for the reply.
