[750hp]

Andy, the V3-J is the closest to what's available there. My peak power figure should be about lineball with the J, but the lowend torque figures will show low rpm losses as compard to the V7 YS Trim

The belt gear ratio is a mystery. I assumed that the ratio would be the ratio of crank pulley teeth to blower pulley teeth ie. 74 & 28. The 1000cfm still looks a little low (but can't change), Pressure ratio ???? - I found out that boost pressure as mentioned is only a peak pressure level (where wastegates in a turbo would be set for example), the pressure ratio is the key to telling the program how much airflow is entering the motor (I think) What happens if you enter 26 in the Pressure Ratio field?

I just found a small review, and they weren't all that complimentary about the forced induction side of the program, but they liked the naturally aspirated side of it....


"However, we did input the data for a well-known single turbo engine (the program won't accept twin turbos) and the power and torque graphs were fairly close to the manufacturer's specs for this engine. However, there was almost no power gain at all when boost was then lifted - a patent absurdity to those who know factory turbo cars. The program having lost credibility in this area, I did not experiment further with forced induction engines.

Conclusion
Costing just US$54.95, we think that the Dyno2000 package is excellent value for money. On naturally aspirated engines, especially when cam changes are being considered, the results are consistent and accurate. The Iterative Testing feature (apparently a first for cost-effective engine simulation software) works well, and the results achieved on all naturally aspirated engines appeared to be very close to the mark. However, we think that the forced induction side of the program leaves something to be desired."

Thanks again,
