I think it's pretty rare that someone is running this setup, that's why the zero response. I'd love to run it someday.

I know a man that ran a 3.1 in his Ultra Van. I believe he ran it on an engine dyno, I have seen the figures, but, I can't locate them now. PM me with your contact info and I will forward it to him.

Here's a few big bore dyno runs:

This is Kent Sullivan's engine in his 66 coupe, you can read about it here: http://www.corvairkid.com/190cid.htm
The graph is a bit awkward to read as the vertical scales are different

Here's Duane Cartwright's engine:

Duane designed and produced the Cartwright Fuel Injection system

3.1 with modern turbo

I'm pretty sure this was built by Ray Sedman at American Pi http://www.american-pi.com/corvair/corvhome.html
