Went to the track - Results
I thought my 94 Firehawk was slow this weekend and still do. My best time was a12.38 @ 109 with a 1.79 60'. I ran consistant 12.40 and .41s I've been tuning this OBD1 for 5 days. Using Tunercat I can't get it to richen at idle (17.5:1) and WOT at 14.7 with the MASS connected open or closed loop. Without the mass it idles at 14.7 part throttle down to 11.5 and wot at 13.5-14.87. I'm running 60# Dekkas running at 27% duty cycle. This is a fresh built 383 12.5-1 motor with a 700r4 full manual and a 3500 stall. I fully believed I'd be into The mid 11s on the motor and 10s with a 150 shot. I'm sure my tuning is the problem. Does anyone have a base tune I can work with? I had a bad NOS feed line so I couldn't use it. Without the mass running lean I got the 12.40s and with I ran 12.8s

We are going to make a few more runs untuned to get that 12 second slip as it sits. Planning on adding a cam and a small shot and a dynotune at Speedinc

We'll see how my immediate budget likes modding the car more
Look like good numbers to me! I bet some 1.6 rockers and spring along with an electric water pump would pick it up some on the top end. That's what i'm recommending to my brother along with some headers as his car pulls hard through the first two gears and then falls off up top.
