First passes with the new D1SC/347 firehwk Weather wasnt that great, 2400' DA, but it was only 67 degrees. The DOT QTP tires I have on there are a couple years old and not the best but I was happy how it ran for th first time out with the car.
First pass was a 6.83/108 with a bad missfire (plugs were crapped up from a lot of idling the last few days), changed the plugs, ran a 6.42 and a 6.37 @ 110mph. Leaned it out a little and finally got the shiftlight set right and ran a 6.29 @ 111.4 with a pretty crappy 1.420 60 foot, figured that was enough for the day. Need to put it in the air and make sure I didnt forget to tighten anything up, change the oil etc. I'm on a 10 minute hacked MAF tune as well so switching to a 2 bar SD should help out some, hard to get the fueling consistent on the PE table.
With some slicks on the car and a 1.35 or so 60 foot it should run in the 6 teens (9.50s 1/4), 6 ohs (9.30-9.40s) in good weather and thats good enough for me. Tune is super conservative and I was using 50/50 93 pump and 104 unleaded, 60lb injectors are about 96% so I cant go much further unless I step up the injectors anyhow. Thats also through a Y-pipe and single 3" muffler, I'm purposely choking the exhaust to keep me from going too far lol.
few passes from today:

Its 7.25/3.7 pulleys, at 6800rpm thats around 55K impeller, max is 62K so it has a bit to go.
So with maxing the blower out and with a better tune you'll have another 5 second D1SC LS1 car, lol.
What heads you running this time around?

Sometimes starting with a clean slate isnt a bad thing, the two cars really arent identical, lot of things I dd different on this one to make it easier to work on and more reliable.
