I just Wonder, have anybody tried to "build" a Engine in Dyno 2000/2003 and built it afterwards and tested it on a Real world Dyno?

I mean how correct is it? any experience?

how close is the result?

I find it a wery nice tool, but I am not shure how much to trust it. after all its just teory and formulas.....

Hi Tom;

I built a magnum headed 360 inputed as much info on cam spec. as I could. The simulation predicted 360 hp with 390 p ft of torque, after getting it tuned as best as I could. I called Westech (one used in CarCraft) set up a appointment. The guy running the dyno asked what I thought it might make I guessed 265-275 hp. The car put out 282 hp first pull. The fuel curve was stable. He suggested a drop base air cleaner that one change brought it up to 294 hp on the next pull. We tried to get more but no other changes made more. This translated to 371 hp and 430 p ft of torque.

your mileage may vary

I used stock magnum heads with a dual plane intake 625cfm Demon carb, the cam was the mopar performance .450/.455 268/272 cam installed straight up. Mopar M1 dual plane. The valve train was swapped for 1.6 roller rockers, use the crane guide bar ones, the compcam ones will break all the time. The Mopar stuff works, all the rockers and pushrod are ~$110.00 not adjustable though. Head gaskets can use either LA or Magnum. For pistons I used C-116P speedpro and moly rings. Fairly simple set up really. The biggest things to watch for are total timing no more than 34 deg. E-mail me for more info.
