Does anybody have a mockup of the northstar engine on Desktop Dyno 2000? I'd like to model some different cam profiles... Thanks for any help!

...I mean I have in the past used the 3.4 DOHC file with 2 extra cylinders, but I'm not sure how accurate it is.. (but it does put it in the 275hp/300tq range)

Which intake are you picking?

I have yet to be able to use the stock cam profiles and get anything resembling a correct curve. Typically what happens is the 275 HP cams outperform the 300HP cams. I wish it were different but until they address the one size fits all intake and the optimum at all rpms exhaust you just won't be able to get realistic numbers. The cylinder filling premise is sound but the application is a bunch of garbage in = garbage out.

I'm using the tunnel-ram manifold.. I agree with you completely though... Somebody needs to redesign it.
