New Dyno numbers for the Mach and GT
I just got back from this mornings dyno runs. I took the GT for a baseling run before I start modifying it and ran the Mach1 to see how it was running. I hadn't dyno'd the mach since Sep last year.
For the GT w/ K&N filter:
222 rwhp / 222 rwtq
I was really happy with those numbers. I was expecting it to be a little less, around 210-215 range since its an automatic.
For the Mach1 w/ SLP shorty headers, magnaflow catted x-pipe and CB, and C&L CAI:
302 rwhp / 322 rwtq
I've got mixed feelings about the Mach1 runs. The first run was done without the Diablopredator and I was really happy with the numbers, the bad part was that it ran way too lean. The A/F was like 13.8 - 14.3, which I kind expected it to do, but not that high. We did 3 more runs with the Diablo and just kept dumping fuel into it, finally got the A/F curve down to 12.5 - 13.4 ish range, but its not a nice flat even tracing. It looked like a Fn rollercoaster. Next week I'm going to go back to the shop and rent the Dyno room and bang on the mach for a while and tweak it a bit better. I'm also going to switch to Bassani Mid-length headers, x-pipe and CB and put the Magnaflow x and cb on the GT (I'm kicking myself for going with Shorty headers).
Final numbers on the Mach1 w/ diablo:
300 rwhp / 320 rwtq (after 4 runs with around 10 mins inbetween pulls).
I'll probably get a wideband 02 sensor for the mach as well, for peace of mind. The shop emailed me the Dyno sheets, but not in a format that I can use or open. So, hopefully he'll send them to me again soon in a format that I can use.
