Interesting Day at the dyno...
We took my step bro's 93 mustang GT (mild heads/cam car) to the dyno. His car had run a best of 13.6 @ 104.xx on street tires with ~2.4-2.6 60's. Well, he makes his first pull and he is in the mid 15's A/F, so we shut it down. I adjust the regulator from 40psi to 47psi...he re-runs again and puts down 248rwhp/278rwtq. Dissapointing, but we kept playing. I richened it up some more so he was at 12.7-13.3 across the board (his A/F profile wasnt quite linear). I also turned his timing up from 13 degrees to 18 degrees. When all was said in done, he ended up with 270rwhp/301rwtq. His peak gains were 22rwhp/23rwtq. He also gained 47rwtq @ 2500rpm and averaged around 30rwtq gain for most of the curve. Good day...his car is alot peppier down low now.
