Dauntless

anybody have this? how accurate/effective is it? i'm kinda interested in getting it. it'd seem to give me more information at ease than anything else. of course, i'm still in the researching phase of my modding. and i'm kinda in the "getting money for modding" phase as well. probly gonna be here for a while. hehe.

I've been using a version of performance trend's software and prefer it myself. It seems to be a lot closer to real dyno pulls either I or customers have had done in the past.

edit - Performance Trends seem to reflect the entire rpm scale better,, especially at low rpm. Both versions do a good job at estimating peak power.

i use it all the time and is about the most usefull tool i've ever used, i use it mostly for cam selections, and the cams i come up with on the D.D. i've run and had fantasic results. one guy i know put in every exact spec of his new engine into the DD (head flow, all cam specs,...etc) and then built the engine and dynoed it and it was within 3 HP from the dyno to the desktop dyno, that sold me on it and i really like this program

Almost every dyno estimation I've ever seen DesktopDyno 2000 do has been within 5% of actual numbers, so it is very useful, in my opinion. In one of the latest Muscle Car Review mags they did an estimate of an Olds W30 engine and came up with 310 hp. On the actual dyno it gave them 310 hp. Pretty hard to beat that, eh?

I fyou just keep in mind that it can run 5% either way, you won't be disappointed.

The accuracy depends on how accurate
your input is. If you tell it lies It'll
lie right back to ya....lol
I find it very accurate when used properly but, by its very nature tends to over estimate bottom end torque. The program always assumes perfect air/fuel ratios and a perfect exhaust design (header). Neither of which happen in the real world. Also a lot more accurate if you use the actual "running seat duration" of a cam instead of the advertized duration or .050" specs. Read the instructions carefully and have fun...

Yes, you want to get Desktop Dyno 2000, its Windows based and a LOT better than the older DOS version. Here is their website: http://www.motionsoftware.com/ You can get it from Jegs or Summit for about $40. I think its worth the price.

I've put both my engine combinations into it, and both times it was within 10 HP. However it way underestimates TPI's torque. Both times, the number it showed as being flywheel torque is what I made at the rear wheels.

Do a search on this board, you'll find other people's opinions as this has been posted many times before.

I have it, and it is as accurate as you can get without actually doing a dyno. You can input everything from actual flow results of your heads to custom cam profiles, gasket thicknesses, etc.. The more accurate information you enter, the more accurate it will be. I have built engines I've seen in several Chevy magazines that had actual dyno results, and it seems to be right in line with the actual results within a few HP or FT/LBS. I recommend it for use in changing where your powerband will be with different cams or setups especially. Order it, you won't be disappointed. It's fun to play with.
