You can download a shareware version of a dyno program that will allow you to kinda build an engine,then Kinda build a car to put it in.It will tell you gross and net HP,1/4 mile times and where you are increasing you ET,it will give you trap speeds,and a bunch of other stuff.The program seems to be biased toward Carbs.I have no connection to the web site or the software,and make no claims of it's accuracy.I just found it one night and downloaded it,I played with it some and figured I'd pass it along.Heres a link to the first page,scroll down till you see Dragplus software on the left.click it ,then click on shareware version of Dragstrip plus to download.Have fun.
