LT1 to Gen I Dyno numbers... Well I got my tune updated for my new injectors by MadZ28 (Ion) and put it back on the dyno. Before the tune I put down 322rwhp and 316 rwtq. This time with the tune I put down 338rwhp and 325rwtq. This is on a Land & Sea dyno, reads a lot like a mustang dyno. The guys there said multiply my numbers by 1.13 and that would be about my dyno jet #'s, so about 382/367 if thats right. Not real happy with the # was expecting more out of it. Here's the dyno sheet and graph. What do you guys think?
Specs: 355 C.I. LT1 to Gen I Conv.
Hyd roller LT1 Regrind 561/573 lift, 230/236 Cam, 1.65 Roller Rockers, Patriot 195cc Port/polished Alum heads 2.02/1.60, 58mm TB, Weisco Forged Flat top Pistons, Balanced/blue printed, 36# SVO, MadZ28 tune, HOOKER Long tubes and 3" Catback, 4.56s...

Far right column in the top pic. It gets richer and richer as the rpms climb. At around 5000 rpms he's at 11.2:1 then it goes down to 10.8:1 by 6500 so the answer is yes...it is too rich. Lean it out and you'll pick up some HP. As for your conversion to DJ numbers, I wouldn't be upset at all if it's putting down 382/367. Looks like you're going through a 12 bolt too (can't imagine running a 4.56 in a 10 bolt)...that will rob some power too.

LOL!! Right there where you see " O2 x 10 " it is reading on the graph at about 160.00 which equals 16.00 AFR. Follow the graph on across and you see it fall on down in the 110.00 to 105.00 range. OR.....
Look at the text printout and it you will see the AFR column like Red99TA said.

And yes it starts out good and gets rich as it goes up. I've been working with Ion (madz28.com) and he's helping me out on getting it tuned correctly. This is a one-of-a-kind car that no one has ever tuned and he's doin a bad *** job.
