Anyone had any experience with this software?
 

ProRacing Sim software has a dyno simulator available that has the capability to tailor an engine build and provide accurate dyno simulations. There is a demo version available that lists a LOT of engines, including the Porsche 911.
Anyone used it? The URL is below;

I would not get my expectations to high on the accuracy of the software. We have tried some expensive software and have yet to be in the ball park software projection vs actual dyno results. We worked with Performance Trends feeding them data from the dyno and it really never went anywhere.

That is why we dyno our ideas to see what they did.
