i have been given a copy of dynosim to have a play with and am curious how you proceed to allow for a twin turboset up i can get the specs for a single turbo which is island flow, surge flow, pressure ratio, and peak efficiency and boost - now for twin turbos do i just double one of these cos that seems to lose power any help?

 

In theory you should just double the flow rate if you are using 2 of the same turbos in Parrallel.

 

Why don't we move this over to the turbo forum where the experts hang...

 

I like the "experts" bit Eric...

 

triedthat but i seem to lose power

 

That seems rather odd.
So you maintain the same boost pressure etc. and just double the flow rate and you loose power... hmm...
I have never used dynoism, so I am not really sure. The only virtual dyno program I have used is Virtual 4-Stroke...
Anyone else used the program, or have any ideas?
