Damn mate nice work, going to do the S&S 106 next year for mine.

is that turbo lag 2000-2750 rpm??

Nice power indeed. Still pulling over 100tq at redline, and HP only just starting to slow !

She'd be a fun ride from 3k up !

Here you go !

Great job Davo, Be nice to have the dyno access to make and check changes the way you can. Us mere mortals just get 1 or 2 goes. Your a lucky man indeed but access is no good if you don't know what your doing I guess.
Look forward to the final result

Have heard a lot of great feedback for S&S 640G's, what cranking pressure are you running?

Nice one Dyno, bet she pulls like a train. 200 Hp with a turbo, would like to see that graph when your done.

Why would you want .7 lift on a 4 valve head?

I always thought that half the reason for the 4 valves is that you can run lower lift cams and still get the same flow as a high lift setup.

What fuel did you use on the 106 run above?
Nice work on gettin 1.25 HP per CI
