DanG,I've reworked your file with all the right numbers...and I'll send it to you on the email address you've quoted in the file...if that's ok..?

What kind of turbo are you simulating..? Usually that happens if you have a turbine or compressor spec really off...or serious restriction somewhere...

By the way guys...the files that was converted to text files work just fine in the Pro if you save it to their respective "User's Spec"-folder... Heads to "User's Head-files" etc...Just remember to save them to your own name,or they'll suddenly disappear from your libraries...if you open another file without saving the "texted" file first it'll be gone.

NZ: What i like to know is this, when you started this thread, you entered the combustion design to be a Hemi Design. I then responded by saying that the combustion design is not a Hemi design, which referes to the cylinder head being "half spherical" or "dome" shapped. You didn't update the info there at all, that is untill Skunk chimed in and helped out.

What i am trying to say is that you started this thread and posted some incorrect data (one being the combustion design), what makes you 100% sure that the rest of the data is correct? So far, only Skunk tested the data, it would be nice that if someone also tested the data (according to what spec you have) and gave us more input (and no, i am not saying Skunk is wrong about anything, you just can't have enough information).

Secondly, just how accurate is this program? i recall you mentioned:

I really like the software some of the 951-engines I have modelled doesn't really turn out as good/correct as I wanted.

But I suppose the main strength is to compare different parts with eachother in the program and see the difference in powerband and peak power. The calculated numbers will however not be the exact numbers of a dyno.

I've only tested 1 (one) stage 3 head. No two heads are alike. It could have been a bad one. **** DOES happen once in a while. But then again...I have a St2 head tested too,and the trend is the same....

I've done that on several types of engines. Given that you get the exact specs for every input,you'll get within a couple percent...but it doesn't take into account a few things it should.

No, but its my problem!!

Nice thread! Keep up the good works.
