It saw 225 for awhile on 91 octane...yikes! It was just junk thrown together to have something to race. It ran 12.90s NA and it was way out of gear on the nitrous.

Quick update on this one. I ran it at Roadkill Nights a couple weekends ago, it did great there and I did spray it for 2 of those passes but I had a mild ramp in the progressive, and it also was on the street so I didn't get any times. I drove it the 40 miles to Milan Dragway last night and got 3 passes in. 1st all motor pass was a 12.58 @ 107, the air was much worse (3000' DA, 80+ degrees out) than when I ran a 12.46 at Norwalk last year, so I was happy the car was performing like usual. Tried to make a nitrous pass for my second one. Purge worked, but the WOT switch didn't make contact and it slowed down to a 12.64. Whoops! Third pass, we fixed the WOT switch, and I was rewarded with a 11.37 @ 118.5!!! Straight up stoked it picked up 1.2 seconds with a 180 shot, I wasn't expecting it to run that well, I was going to be happy with an 11.80 or better due to the weather conditions, and I think I startled the timeslip lady when she handed it over. I was watching the wideband in the car and it was not going lean going through the traps, so that gives me hope that the mechanical pump is keeping up with the fuel demand, and I have some margin to jet it up just a smidge more. Now I'm already thinking about what I can do to get just one 10.9x timeslip out of it. Figure that's plenty quick for no rollbar, stock lap belts, a column shifter, and 4300 pounds!!

NICE ! Congrats So happy you hit that goal.....AND almost exceeded it !! By the looks of that mph and 60foot , there is plenty left in it What was the wideband reading?? Looks like that nitrous bug got you now

Thanks Jerry! NICE ! Congrats So happy you hit that goal.....AND almost exceeded it !! By the looks of that mph and 60foot , there is plenty left in it What was the wideband reading?? Looks like that nitrous bug got you now Totally hooked!!! Thank you so much for the advice both here and in PM's, and the congrats. I couldn't be happier with it, although I'll say that again when I get it in the 10's, lol It's so heavy I think it still needs more gear to get off the line. I might step down to a 275 pro to shorten the final drive up some and help it out. It didn't really spin and I don't have a trans brake so I'm not sure how I can get it to launch any harder besides giving it more gear ratio or swapping the converter. I have the wideband reading in lambda so it was 0.80-0.82 when I looked at it at in 3rd, so 12.05-ish to 1 air fuel. I was so happy I packed up and didn't bother to check plugs after the pass, but I did at Roadkill Nights after a nitrous pass and they looked great, the timing mark was about where it needed to be. I ran Roadkill on straight 93. Timing is 38* on motor, and then I had the timing retard pull 9* when the nitrous is activated. It's got a 73 jet in the plate and to be safe I ran it on a 50/50 mix of 93 and 100. I'm guessing I could've pulled a degree or two less timing on the race gas and it would've still been ok.

Remember to approach your tuning in baby steps, easy to get greedy and hurt it Optimize what you have before going to a bigger jet, then you know what A/F and timing the engine likes so you close when going to a larger jet First thing i would look at is the AF, 12.0 is a tad rich im sure. Leave the timing low and lean it out 1/2lb at a time ( Induction Solutions has flow gauge on sale right now) Or just reduce the fuel jet .02 or so at a time Once you get the AF good , what to look for, drop in fuel and it picks up MPH, you went the right way Once the AF is good, add a .5 degree or 1.0 degree at a time, Again if it picks up...its good, if not go back. Check a plug or two, at least look for heat on the straps. On a BB mopar no heat is good, or just on the edge of the strap thats it you will be surprised how much these two things will pick the car up, i bet you can go over 120mph. As far as that 60 foot....have you been purging before a pass?? IF not you will see a big difference for sure. Even if you bang it through the engine it will help a lot. Happy ET hunting

Thank you Tony! I need to print this off and paste it in my track toolbox as a reminder how to not hurt it. This is great info, especially about the timing. It makes total sense to not bother advancing it if it doesn't pick up any mph. I did purge before that pass. I was originally going to just bang it through the motor but with how the mini progressive is set up I would've had to add a few diodes to the circuit I wired in, and figured it was easier to just put a purge solenoid on it. I drilled out the antenna and ran the line through the antenna hole. Thinking about the launch further, I could've left a little further up against the converter. I was only at 2500 or so when I left, my car is heavy enough it probably will benefit from it. I have the nitrous set up on a window switch from 3500 to 6500 plus the WOT switch, so it shouldn't be a big deal if I get it to 3500 footbraking. I've watched the video of my car a few times and I'm thinking I need to ditch my air shocks for sure as well, I don't think they're controlling the rear well enough. Thanks to you guys I have a few things to try next time out, and I hope I can get a couple more tenths and 1-2 more mph out of it without upping the nitrous jet yet. Jeff - it's just a good angle, lol. It would pick up 1.5 tenths just with you driving it, but I think your head would explode at my shifter setup! Wes, thank you, really appreciate that. I've put about a thousand miles on it this year. It's just a fun car to cruise, and I'm having even more fun with it now that it's getting to be decently quick. I really hope 10's are just around the corner!

3.5" pipes, 2 chamber Flowmasters, and no tailpipes. Not terribly classic of a sound but I love it.... and my neighbors do not. lol Saw you on the live feed! Next year I'm definitely going to try spraying it out of the hole out there, the road was surprisingly good. They missed my one good, close run against an early Nova. I lined up against Jim for all of the others, and his Charger made it look like the Fury still had a 318 in it... especially with my naps for reaction times.
