I bought Virtual Engine 2000 ($40) and found it was a lot different than Dyno 2000... it is easier to enter the cam data, but now my 333 HP LM7 is only rated at 215 HP (SAE Standard) .

I was messing with my desk top dyno with the tr220 112 it said about 380 horses. but i dont think the torque curve is correct it said over 400lbs

Thats pretty weird with the change in output power you are seeing supra... As far as converting regular cam data to what DD needs, I am just as lost as you. Jeff i get about the same as you with the MTI C2 profile i have... its pretty crazy..

There is no formula to calculate valve events from durations @ .050. If this was the case, every cam with the same durations would be exactly alike. The only way to get the valve events is from the maufacturers cam card, or by using cam doctor on an existing cam.

Thanks Tdrumm, I was afraid of that, I'm sure my educated guesses are off by a bit on DD2K.

I found that on Virtual Engine 2K by changing the exhaust from stock to "high flow single", the HP jumped to 324 @ 5000 & the TQ is 367 @ 3500. I still need to figure this program out, but it is easier to use for bench motor building since you don't have to guess at valve timing.

I found that Crane Cams has Gen III cam card info on their website, and entered a few as DD2K files. I zipped them & have attached the file.

I've run several combos w/ VE2K and am getting the hang of it, still a good bit of variation between the two for some reason.
