[Land-speed] Landracing.com & Engine Analyzer Software

[Dave Dahlgren]

Well Neil what did you pay for it???

I used a long while back a program I think called dynomation and it was 
pretty good gave pressure volume graphs and wanted to know everything about 
the engine. funny I don't think any of them ask about the oiling system and 
there is a lot there. Wet sump vs. 5 stage dry sump is a big deal all on 
it's own..
Now the current stuff is the Ricardo software though you may want to rent 
some time on it rather than buy it. Personally I wish the Fluent CFD package 
for cylinder heads would come down a little bit and I might be a player for 
it. I already have a solid modeling package so it would basically be a take 
the model and have Fluent blow some air through it and tell me the bad or 
good news..
