i got some test runs last October at a track rental and it had a shake to it then so i didnt turn it up past 20psi and only went 130mph with a 72P turbonetics, no grip with 1.55 60s spinning well through 1st gear,then a map sensor failure ended the day (xfi and alky were caput)
first pass this year with many changes since then , pulled the 72P and setup a 71hpq with a 4 bolt 81 housing that i changed ffroma 3"to a 3.5" vband flange , 15x10-15x6 alumastars, 275 mickey pros / 15x6 mickey SR's , ic relocate setup, fuel cell w/weldon pump, tr6. trimmed some weight ... kirkey pro driver seat , strange discs in rear, ac deleted , deka battery, trz rack n pinion , cm trans xmember , frame notch to tuck in the 5" backspace 10" alumastars , and some other stuff
was just looking for a test pass tonight to feel the car out so only planned to run the 1/8th ,
didnt touch the msbc-1 boost controller .. launch set at 2psi run at 14psi (+spring) and forgot what spring i had in gate so i wasnt going to mess with it
felt a little uneasy coming to the line not knowing what to expect
forgot to start the log on laptop with space bar , knock gauge was quiet , didnt trip the internal logger so no data .. didnt even look at boost gauge
only data was the time slip
1.43 soft launch slipped a little ..
6.29 110.73
10.46 @90mph ..... hit brakes hard after 1/8
so i went back for another pass with everything the same as the first run so i could get the data . figured it should be a low 10.0 so i was going to stay in it
1.475 ..
4.112
6.305 @ 111.76
8.209
9.829 @ 139.04
reviewed the logs
slipped back off the pedal on the hit and it had to pull back up from a tps at 21%, boost at 5.4psi and A/F dropped to 9.3
20deg timing
af 10.6-10.8
injectors at 62-63%
alky 125 psi
air temp in intake 61 Deg F very steady after 1st gear through entire run
base fp 45, running FP 65 steady
bat 14.2 no v-booster ,hotwired the xfi, 200A powermaster
shifted 1-2 5950, 2-3 5900 trapped 6050
converter slip is only at 5.0% with 666 hp to the wheels
running boost was only 20.6psi !!
i also spent sometime over the last week getting some weight out of murphster's T type . he was there tonight andshot a video of the run (looks slow to me) and he went to get his ttype on the scales .. maybe he will post the results
have a feeling when he gets down the track even without turning it up any from his last passes no one is going to believe the slip
