I took my new combo to the dyno over the weekend and things didn't go as I hoped. Its a 8.5 to 1 331/AFR 205/ Victor 5.0 and a small s-trim. I have the full Aeromotive fuel system 42lb injectors and a prom-m 83mm mass air.
I could only get 441/433 safely out of it and this is pushing it. The air/fuel was great until about 5200 then it went from 12 to over 14 at 6000. My timing was only 14° with 1/2° on the btm. At first fuel pressure was 40psi so I turned it up to 42 and a/f didn't change much.
Whats going on? Are the 42's just to small or do I have another problem else where? Will try to get the chart scanned in and posted. Thanks for any help.
