Well I was toying with the airflow & jetting on the old 89 yesterday so I took it down to the local 1/8 mile last night. I picked up a little power on the big end neeed to go back to the 1/4 now to see how its really running. 1st pass RT .071 60 ft 180 ET 7.277 @ 98.63 2nd pass RT .020 60 FT 1.746 ET 7.295 @ 95.23 MPH 3rd passs RT .015 60 FT 1.700 ET 7.247 @ 94.68 probably gonna go back to the 1/4 next week.
