Default 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:

Awesome
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?

I'd have to lose a little more weight, go to some 75-83lb injectors and change the exhaust to get in the 5s safely/consistently. I'm happy the way it is, I just need to get the 60' down a little. Thats 50/50 tires/tuning right now.

I have AFR 225s on it.

I'm going to leave it for now, if anything I'll put a flowmaster 3" to 4" merge and run a 4" muffler, that was good enough for 8s on my other car.

Cool. Good luck with the rest of your fine tuning.

Nice runs! But I have to ask...why did you put all the effort into building a car, then selling it, then turning around and building an almost identical car? Just curious

The other car did a really big wheelstand and came down and did some serious damaged to the chassis and he decided to not fix it

Said 3560 with me in it at a truck stop scale which seems a little heavy, I'll have to wait to I get a track with a good sale and see for sure. 13.5-14psi at peak is what I seen on the logs.

I raced the old TA for 3.5 years and I got my money's worth out of that car, I had nothing against it, was just sick of looking at it. I didnt put that much effort into either of them really and the TA pretty much paid for this one.

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.

It didnt hurt the chassis on the other car, it broke the oil pan/engine block, bent up some intercooler pipes and the headers. The old TA is getting a BBC and will be an 8.50 index car in Wisconsin.
